Among the \nfour dimensions of IEQ, the climatic quality of the building - understood as the com-\nbination of thermo-hygrometric conditions and air quality - is taken over by the HVAC \nfunctions and is of fundamental importance for its energy implications.\nHVAC with Ekinex®\nEkinex®, the Italian company specialized in the realization of KNX devices, offers \nadvanced solutions for the control of room climatization.

This \ninnovative standard was born from the merging of three European systems (EIB, \nBatiBUS and EHS), developed and brought to the market in the early 90’s. The diffusion \nof the system was facilitated by an intense work of cooperation at normative level in \nthe standard committee at European level. For this reason, too, KNX is a standard \ncharacterized by a total conformity with norm EN 50090 on electronic systems for the \ncontrol of homes and buildings (HBES, Home and Building Electronic Systems).\nThe presence on the market of this standard since 1991 offers the best guarantee \nin terms of reliability and consolidation of the technology used. The openness of the \nstandard and that of the KNX Association, on the other hand, ensure availability of \nproducts in the long run and a constant development, both in terms of technology and \noffering of products, functions and applications.\nThe vitality of KNX proposals is witnessed by the sustained expansion of the association,\nseeing the entry of manufacturers, coming from many different areas, and from the tens\nof thousands of technicians who chose it to specialize in the field of building automation.\nAchievable savings with the adoption of the KNX system for Home & Building control:\n• 40% over shutters control\n• 50% over individual ambient control\n• 60% over ambient lighting control\n• 60% over ventilation control\nFor customers, the variety and availability of KNX products has no comparison in other \ntechnological areas, and the system openness translates into the highest free choice, \nthereby avoiding the disadvantageous dependence of having to buy from a single sup-\nplier. Thanks to the modularity of the system, a project can be extended in time, starting \nwith a basic configuration and adding more functions later. The native interoperability of \nKNX products is fundamental to technicians, as it allows to design a system by always \nchoosing the most suitable technical options, reducing compromise and ties caused by \nproprietory systems which do not communicate with one another.\nMoreover, the system offers new professional opportunities to designers and system \nintegrators, making it possible to receive a consistent and high-level technical training \nand become certified KNX Partners.\nThe KNX standard\nThe KNX standard is entirely compliant with\nnorm EN 50090 on HBES (Home and Building\nElectronic Systems) systems)\n6\n7\n",4,{"image":30,"text":31,"number":32},"\u002Fmedia\u002Fimages\u002Fcd\u002Fc5abf5967dca696a45458fe77a3ccc-26fdbc40ba.5.png","HVAC APPLICATIONS\nHVAC APPLICATIONS\n4-fold pushbutton with room thermostat function (FF series)\n4-fold KNX pushbutton (max. 8 independent bus functions), with \nintegrated temperature sensor and room thermostat function, for \ncontrolling loads, dimming luminaires, controlling blinds and shutters or \nother programmable bus functions.

If necessary, a weighted average between the temperature \nvalue measured by the sensor integrated in the room thermostat and the value received \nvia bus from another device (e.g. from an Ekinex® pushbutton or multisensor) can be \nused for adjustment.\nEkinex devices\nA) Time \u002F astronomical digital switch  EK-TM1-TP \nB) GPS module EK-GPS-1 \nC) Actuator-controller for electrothermal drives EK-HE1-TP\nD) Room thermostat EK-E72-TP\nE) Server Delègo EK-DEL-SRV-...\nF) Touch-panel Delégo EK-DEL-xPAN...\nOther system components\n1) Thermal generator\n2) Run \u002F stop contact\n3) Zone valve with ON \u002F OFF servomotor\n4) Distribution manifold\n5) Radiator\n6) Towel warmer\n7) Access point LAN Wi-Fi\n8) Switch\n9) Smartphone with Delégo App (Apple iOS or Android)\nHeaters system\n1,50 m\n0,30 m\nExamples of applications\nHeaters system \n15\nFan-coil systems \n16\nRoom control in hotel building \n18\nAccess control \n19\nControl of a mixing group \n20\nFloor radiant system in residential buildings \n22\nCeiling radiant system in residential buildings \n24\nCeiling radiant system in functional buildings \n26\nAir renewal with energy recovery ventilation units \n28\nAir renewal with VAV boxes \n29\nInterfacing VRF systems \n30\nConsumption monitoring \n31\nDelégo supervision system \n32\nControl with home speaker \u002F voice assistants \n33\nFurther information\nIndoor Environmental Quality (IEQ) \n34\nThermo-hygrometric comfort \n35\nAir quality \n35\nBuilding automation and European directives \n36\nEnergy classification of buildings (EN 15232) \n36\nEnergy classification of radiant systems (UNI \u002F TR 11619) \n37\nSustainability certification \n37\nHVAC WITH EKINEX®\nZon� 1\nZon� 2\nE\nDig\nK-\nit\nT\nal\nM\nt\n1\ni\n-\nme\nTP\n \u002F Astronomical switch\nLine\nDev.\nArea\nbus KNX\n1A\n3\n4\n1\n2\n7\n8\n5\n6\n1B\n2B\n2A\n3A\n11\n12\n9\n10\n3B\n4A\n4B\nL\nN\n15\n16\n13\n14\nL\nN\nN\nN\n1\n2\n3\n3\n4\n4\n5\n5\nA\nB\nC\nD\nD\nIP\nE\n6\n7\nF\n8\n�������Supervision\n9\n6\nR EK-DEL-SRV\nDelégo Server\nExample\n15\n",8,{"image":46,"text":47,"number":48},"\u002Fmedia\u002Fimages\u002Fcd\u002Fc5abf5967dca696a45458fe77a3ccc-26fdbc40ba.9.png","HVAC APPLICATIONS\nHVAC APPLICATIONS\nEkinex devices\nA) Time \u002F astronomical digital switch  EK-TM1-TP \nB) GPS module EK-GPS-1 \nC) Room thermostat EK-EP2-TP\nD) Actuator-controller for fan-coils EK-HA1-TP\nE) NTC temperature sensor (contact) EK-STC-10K-3435\nF) NTC temperature sensor (immersion) EK-STI-10K-3435\nOther system components\n1) Fan-coils units\n2) Valve with ON \u002F OFF servomotor\n3) Heat exchange battery\n4) Fan group\n5) Contact for condensate drip tray\n6) Window contact\n7) Thermal generator (warm fluid)\n8) Thermal generator (cold fluid)\n9) Boiler room manifold (flow)\n10) Boiler room manifold (return)\nFan-coils are terminal units that are widely used in offices, shopping centres, hotels and \nhospitals and, in general, in medium-large buildings. \nFan-coils are used in hydronic systems for room heating and cooling, using small \nterminals for convection heat exchange (with prevailing forced effect). One or two \nbatteries for water-air heat exchange, a fan unit and the actuating devices (2 or 3-way \nvalves with electrothermal actuators or servomotors) to regulate the flow rate of the \nheat transfer fluid to the exchange battery provide for this. Some versions can be \nequipped with an auxiliary heating battery powered by electricity. \nIn addition to the units with the traditional 3-speed fans, there are also versions with \nbrushless motor and inverter board that allow a continuous control of the fan speed by \nmeans of a 0-10V control voltage.\nFrom a construction point of view, the fan-coil units can have different shapes, such \nas cabinets for ceiling or wall mounting; the ceiling versions can be stand-alone or \nconnected to air ducts installed in the plenum. \nControl with Ekinex\nThe application examples show two different and very common system configurations. \nIn the first case (example I), the fan-coils (1) are equipped with a 3-speed fan unit \nand connected to a 2-pipe heat transfer fluid distribution system. In the heat exchange \nbattery (3), warm or cold fluid circulates alternately and the flow is controlled by the \nvalve (2).  \nThe room air temperature is controlled by room thermostats EK-EP2-TP (C) and \nactuator-controllers for fan-coils EK-HA1-TP (D). The room thermostats (C) are \nconnected to the window contacts (6) and contact temperature sensor EK-STC-\n10K-3435 (E), while the actuators (D) are connected to condensate drip tray contacts \n(5) and immersion temperature sensors EK-STI-10K-3435 (F) installed on the inflow \npipe of the heat transfer fluid. \nIn this application, the switchover between heating and cooling can be carried out \nautomatically, by measuring the temperature of the fluid arriving from the distribution \nby means of an immersion temperature sensor (F) connected to an actuator input (D). \nAlternatively, Ekinex® devices can receive the switching control via bus (centralised \nmanual switching mode).\nFan-coil systems\n2\n1\n3\n4\n5\nIN1\n4\n3\nC\n1\n1\n2\n1\nV1\nV2\n3\n1\n4\n1\nV3\n5\n1\n6\n1\nDO1\n7\n1\n8\n1\nIN2\n7\n8\n5\n6\n9\n0\n1\n1\n2\nL\nN\nDev.\nLine\nArea\nbus KNX\n230Vac-50\u002F60Hz\nR\nEK-HA1-TP\nFan-coil actuator\u002Fcontroller\n6\n9\n10\n7\n8\nT\n2\n1\n3\n4\n5\nIN1\n4\n3\nC\n1\n1\n2\n1\nV1\nV2\n3\n1\n4\n1\nV3\n5\n1\n6\n1\nDO1\n7\n1\n8\n1\nIN2\n7\n8\n5\n6\n9\n0\n1\n1\n2\nL\nN\nDev.\nLine\nArea\nbus KNX\n230Vac-50\u002F60Hz\nR\nEK-HA1-TP\nFan-coil actuator\u002Fcontroller\n6\nT\nEK-TM1-TP\nDigital time \u002F Astronomical switch\nA\nB\nC\nC\nD\nD\nE\nE\nZone 1\nZone 2\nT\nT\nF\nF\nBoiler room\nExample I (2-pipe distribution)\n2\n1\n6\n7\nEK-TM1-TP\nDigital time \u002F Astronomical switch\nA\nB\nC\nD\nIN1\n4\n3\nC\n1\n1\n2\n1\nV1\nV2\n3\n1\n4\n1\nV3\n5\n1\n6\n1\nDO1\n7\n1\n8\n1\nDO2\nIN2\n6\n5\nIN3\n8\n7\n0-10V\n9\n0\n1\n1\n2\nL\nN\nDev.\nLine\nArea\nbus KNX\n-\n+\n230Vac-50\u002F60Hz\n3\n1\nR\nDO1\n2\nDO2\nEK-HC1-TP\nFan-coil actuator\u002Fcontroller\n3\n4\n5\nT\nE\n8\n9\nRoom or zone\nF\nBoiler room\nExample II (4-pipe distribution)\nIn the second case (example II), the fan-coils (1) are equipped with two heat \nexchange batteries (3, 5) and a fan unit with brushless motor controlled by an inverter \nboard. The units are connected to a 4-pipe heat transfer fluid distribution system. With \nthis kind of distribution, if both fluids are available from the boiler room, there can be \nheated and cooled rooms simultaneously in the same building; the flow is controlled by \ntwo valves with ON \u002F OFF servomotor (2, 4). \nThe room air temperature is controlled by room thermostats EK-EQ2-TP (C) and \nactuator-controller for fan-coils EK-HC1-TP (D) which have an output with the \n0-10V voltage required for a continuous control of the fan speed, obtaining all the \nadvantages of these terminals: more precise response to the variation of heat loads, \nbetter temperature stability, reduced noise and high efficiency even at partial load with \na consequent reduction in electricity consumption. Temperature attenuations can be \ncalled up automatically in the absence of people, thanks to the presence sensor EK-\nDF2-TP (F). \nIn this application, an automatic switchover between heating and cooling, based on \nmeasured temperature and setpoint values, can be advantageous. Alternatively, and \nwith both transfer fluids available, the switchover can also be performed locally on the \nroom thermostat in manual mode. In both cases, several utility functions for comfort, \nenergy efficiency and system maintenance can be added according to the needs of \ncustomers and end-users: a few examples are given below.\nComfort\nThe contact temperature sensor (E) installed on the heat exchange coil allows the fan \nunit (4) to be started only when the temperature of the heat transfer fluid is comfortable \nfor the users (warm-start function). If the sensor (E) is missing, the function can also be \nperformed by setting a simple start-up delay. \nIn rooms with big height and volume (atriums, gyms, commercial rooms), air \nstratification can occur, with energy waste and discomfort for the end-users. To limit this \neffect, a temperature sensor (E) is connected to the thermostat (C) and a maximum \ntemperature gradient is configured that must not be exceeded.\nEnergy saving\nThe window contact (6) connected to an input of room thermostat (C) automatically \nswitches the operating mode from comfort to building protection, avoiding the loss of \nheating and cooling energy to the outside. \nMaintenance\nThe actuator-controller (D) is provided with an operating hours counter which increases \nthe count when the fan unit (4) is set at least at first speed. When the set time interval \nis reached, a signal is activated to replace the filter of the fan-coil unit.\nEkinex devices\nA) Time \u002F astronomical digital switch  EK-TM1-TP \nB) GPS module EK-GPS-1 \nC) Room thermostat EK-EQ2-TP\nD) Actuator-controller for fan-coils EK-HC1-TP\nE) NTC temperature sensor (air) EK-STL-10K-3435\nF) Presence sensor EK-DF2-TP\nOther system components\n1) Fan-coil unit\n2) Valve with ON \u002F OFF servomotor (warm fluid)\n3) Heat exchange battery (warm fluid)\n4) Valve with ON \u002F OFF servomotor (cold fluid)\n5) Heat exchange battery (cold fluid)\n6) Contact for condensate drip tray\n7) Window contact\n8) Thermal generator (warm fluid)\n9) Thermal generator (cold fluid)\n16\n17\n",9,{"image":50,"text":51,"number":52},"\u002Fmedia\u002Fimages\u002Fcd\u002Fc5abf5967dca696a45458fe77a3ccc-26fdbc40ba.10.png","HVAC APPLICATIONS\nHVAC APPLICATIONS\nAccédo software suite\nSoftware for the integrated management of technological systems, \nparticularly suitable for accommodation and hospitality structures (hotels, \nresidences, guest houses or bed & breakfasts).

Alarms from anti-condensation probes can be managed.\nThe digital outputs, not used to activate a circulating pump, can be configured to \ncontrol a zone valve servomotor located on a circuit dedicated to fan-coil units or \ndehumidifiers.\nTo create automation logic, the device is also equipped with 2-channel logic functions \n(16 inputs per channel) with exclusive AND, OR, NOT and OR blocks and delayed \nactivation of the corresponding output.\nTerminal no.\nLabel\nConnection\n3-4\nIN1\nInput 1 (fl ow temperature sensor)\n5-6\nIN2\nInput 2 (return temperature sensor)\n7-8\nIN3\nInput 3 (outdoor temperature sensor)\n9-10\nIN4\nInput 4 (confi gurable as AI or DI)\n11-12\nIN5\nInput 5 (confi gurable as AI or DI)\n13-14\nAO1\n0-10 V control output for servomotor\n15-16\nPOWER AUX\nTRIAC power supply (230 Vac o 24 Vac)\n17\nCLOSE\nControl output for servomotor (closing)\n18\nCOM\nControl output for servomotor (common)\n19\nOPEN\nControl output for servomotor (opening)\n20-21\nDO1\nUscita a relè comando circolatore\n22-23\nDO2\nRelais output (additional functions)\n24-25\nDO3\nRelais output (additional functions)\nInputs and outputs\nSwitching the seasonal conduction mode\nThe seasonal (heating \u002F cooling) mode can be switched in three ways:\n- from the KNX bus; \n- via the front keypad of the controller;\n- by means of a switch connected to an input of the controller.\nIf switching from the KNX bus is selected, the controller receives the conduction mode \nfrom another bus device (via a communication object), such as an Ekinex® room \nthermostat, which has been assigned the master function for seasonal switching. \nSwitching can be carried out manually using the keypad and the display on the front of \nthe device: in this case, it is the EK-HH1-TP controller that performs the master function \nof seasonal switching for all Ekinex® devices (sensors, actuators) that are on the same \nsystem or part of a system served by the controller.\nSwitching via a switch connected to input IN5 (configured as DI) is suitable for stand-\nalone applications in which there is no need for integration between the boiler room \n(primary adjustment) and the rooms or zones (secondary adjustment). The switch can \nbe the same as the external selector used in the boiler room for switching the operation \nof heat generators or shut-off valves of fluids.\nThe current operating mode is stored in the non-volatile memory of the controller. \nActivating the mixing group\nThe mixing group can be activated in three ways:\n- from the KNX bus;\n- from a controller input;\n- from a controller input and the KNX bus.\nBy selecting the activation from the KNX bus, the controller connects in logical OR the \nflow requests coming from a maximum of 16 Ekinex® room thermostats. To activate the \nmixing group it is sufficient that a single room thermostat requires flow. \nThe activation from an input is suitable for stand-alone applications in which there is \nno need for integration between the boiler room (primary adjustment) and the rooms \nor zones (secondary adjustment). A time programmer can be connected to input IN4 \nto activate the group according to scheduled time slots or the request of a stand-\nalone room thermostat. In systems with distribution manifolds, the limit switches of the \nelectrothermal drives mounted on the individual valves can be connected in parallel.\nAn intermediate solution, on the other hand, involves activation both from the binary \ninput and from the KNX bus. The input can have priority over the flow requests coming \nfrom the zones via bus (for example an external time zone programming device) or it \nbehaves as an additional zone (without priority). \nIn all cases it is possible to set an activation delay (from 1 to 255 seconds) for the \nstart of mixing; in fact, it is advisable to wait for the electrothermal drives to bring the \nvalves into the open position to prevent the circulating pump from exerting pressure on \nhydraulically closed circuits.\n20\n21\n",11,{"image":58,"text":59,"number":60},"\u002Fmedia\u002Fimages\u002Fcd\u002Fc5abf5967dca696a45458fe77a3ccc-26fdbc40ba.12.png","HVAC APPLICATIONS\nHVAC APPLICATIONS\nThe floor radiant system is a widespread hydronic system for heating and cooling rooms. \nThe heat transfer fluid circulates inside circuits made up of plastic pipes placed under \nthe surface covering of the floor; in the most common version, the pipes are laid on \nan insulating layer and embedded in the cement base. The system is invisible and uses \nthe whole surface of the floor as a large terminal for the heat exchange prevailing at \nradiation. In both seasons the system works with a very limited temperature difference \nbetween the heat transfer fluid and the room air; for this reason it is also defined as \na“low-temperature difference” heating and cooling system.\nThe system shown in the example is intended for a residential building. It is a combined \nsystem, i.e. it combines the radiant floor panels with one or more fan-coil units, mainly \nfor the integration of sensible loads in cooling conduction mode. \nControl with Ekinex\nThe EK-TM1-TP time \u002F astronomical digital switch (A) ensures that the system is allowed \nto operate according to predefined time scheduling and is constantly synchronised with \ndate and time by the (optional) GPS module EK-GPS-1 (B).\nThe need to produce heat transfer fluid at two different temperatures for the combined \nsystem (consisting in floor radiant panels \u002F fan-coil units) is solved by controlling a \nmixing group with the EK-HH1-TP controller (I). The device controls a mixing valve and \na circulating pump; by means of the EK-STI-NTC-3435 sensors (M, N) it can measure \nthe flow and return temperatures of the heat transfer fluid. On the unmixed circuit it can \nalso control, as required, a circulating pump (7) or a zone valve.\nThe room air temperature is controlled by room thermostats EK-EQ2-TP (E), measuring \ntemperature and relative humidity, in combination with actuators-controllers for \nelectrothermal drives EK-HE1-TP (O) and actuators-controllers for fan-coils EK-HC1-\nTP (C). The thermostats are able to calculate and send to the bus the dew temperature; \nif the thermo-hygrometric conditions of the room are close to those critical for the \nformation of condensation on the cooled surfaces, it is possible to implement one of \nthe several protection strategies provided by the Ekinex® thermoregulation system (see \ntable on the right); for example, recalibration of the flow temperature of the heat transfer \nfluid through the EK-HH1-TP controller (I).\nThe optional supervision by means of the Delégo Server (G) allows you to monitor and \ncontrol the home automation system by means of an App for mobile devices (9) and\u002F\nor a Delégo touch-panel (H).\nTwo-stage system (main \u002F auxiliary)\nIn the system configuration of the example, the room thermostat EK-EQ2-TP (E)\nallows you to easily realise a two-stage heating \u002F cooling system. When the main stage \nconsists of a radiant panel system, the high inertia (especially typical of the version \nwith cement base), makes it rather slow in the start-up phase to achieve comfort \nconditions. In this case, it is possible to configure the fan-coils as an auxiliary stage; \nthanks to their much lower inertia, they contribute in the initial phase to quickly heat or \ncool the room and then stop their action when the difference between the measured \nand setpoint temperatures can be satisfactorily addressed by the main stage alone. The \nauxiliary stage works in automatic mode with a configurable offset with respect to the \ntemperature setpoint set for the radiant floor (main stage). \nPrevention of condensation in cooling conduction mode\nIn summer cooling operation, the latent loads (due to the increase in the humidity level \nin the room) are taken care of by the air handling integration.\nIf this is not done satisfactorily, or in the event of a sudden change in thermohygrometric \nconditions (e.g. due to accidental stopping of the machines or opening of windows), \nadditional safety measures must be taken to prevent or limit the formation of \ncondensation on cold surfaces.  The EK-EQ2-TP (E) room thermostats provide various \nactive and passive protection strategies depending on the system configuration and the \npresence of home automation devices.  \nActive protection is always preferable, as the intervention tends to prevent the conditions \nof formation of condensation, while passive protection intervenes when the formation of \ncondensation has already begun.\nSurface temperature limitation\nIn some cases it is advisable to limit the surface temperature when the radiant floor \nsystem is used as an auxiliary stage for heating; the dispersions to the outside of the \nbuilding are handled by the main heating system, while the auxiliary stage works only to \nmaintain the temperature of the floor at a pleasant level in the bathrooms of residential \nbuildings or in the rooms of sports centers, spas, etc. This limitation is also included in \nthe EN 1264 standard (Underfloor heating, Part 3) which defines the maximum allowed \ntemperature (TSmax) for the surface of the floor from a physiological point of view as \nfollows:\n- TSmax ≤ 29°C for areas of normal occupancy of the rooms;\n- TSmax ≤ 35°C for the peripheral areas of the rooms.\nFloor radiant system in residential buildings\nMain\nheating system\n \n(high inertia)  \nAuxiliary stage  \n(low inertia)  \nThermal power supplied [W]\n  \nt\n \nT\nT\nT\nT\nT\nzone 2\nzone 1\nzona 1\nzona 2\nBoiler room\nLow-temperature distribution\nMixing substation\nAir integration\nA\nB\nC\nD\nE\nE\nF\nF\nI\nL\nM\nN\nO\n1\n2\n3\n7\n8\n9\n10\n11\n12\n13\n13\n14\n15\n16\nIP\nDelégo supervision system\nG\n4\n5\n6\n�\nExample\nEkinex devices\nA) Time \u002F astronomical digital switch  EK-TM1-TP \nB) GPS module EK-GPS-1\nC) Actuator-controller for fan-coils EK-HC1-TP\nD) NTC temperature sensor (contact) EK-STC-NTC-3435\nE) Room thermostat EK-EQ2-TP\nF) NTC temperature sensor (air) EK-STL-NTC-3435\nG) Delégo server EK-DEL-SRV-...\nH) Touch panel Delégo EK-DEL-xpan...\nI) Mixing group controller EK-HH1-TP\nL) NTC temperature sensor (external) EK-STE-NTC-3435\nM) NTC temperature sensor (immersion, flow) EK-STI-NTC-3435\nN) NTC temperature sensor (immersion, return) EK-STI-NTC-3435\nO) Actuator-controller for electrothermal drives EK-HE1-TP\nOther system components\n1) Window contact\n2) Fan-coil unit\n3) Valve with ON \u002F OFF servomotor\n4) Access point LAN Wi-Fi\n5) Switch\n6) Smartphone with App Delégo (Apple iOS or Android)\n7) Circolating pump for unmixed circuit\n8) Mixing group\n9) Mixing valve with servomotor\n10) Circolating pump for mixed circuit (floor radiant system)\n11) Distribution manifold for low-temperature circuits\n12) ON \u002F OFF electrothermal actuators\n13) Condensation sensor\n14) Thermal generator (warm and cold fluids)\n15) Boiler room manifold (flow)\n16) Boiler room manifold (return)\nType\nMode\nAction\nPassive\nWith condensation sensor (13) connected \nto an input of the room thermostat (E)\nClosing of the circuit serving the involved room \nby means of the actuator (O)\nWith condensation sensor communicating \nwith the thermostat (E) via KNX bus\nClosing of the circuit serving the involved room \nby means of the actuator (O)\nActive\nComparison between fl ow temperature \n(fi xed design value, ETS parameter) and \ndew temperature calculated by the room \nthermostat (E)\nClosing of the circuit serving the involved room \nby means of the actuator (O) when the fl ow \ntemperature is lower than the dew temperature\nComparison between fl ow temperature \n(measured value received from the KNX \nbus) and dew temperature calculated by \nthe room thermostat (E)\nClosing of the circuit serving the involved room \nby means of the actuator (O) when the fl ow \ntemperature is lower than the dew temperature\nThe dew temperature from the thermostat \n(E) is sent via KNX bus to the mixing group \ncontroller (I)\nCalibration of the cold fl uid fl ow temperature \nby the controller (I) and maintenance of the \nopening of the circuit serving the involved \nroom by the actuator (O) \n22\n23\n",12,{"image":62,"text":63,"number":64},"\u002Fmedia\u002Fimages\u002Fcd\u002Fc5abf5967dca696a45458fe77a3ccc-26fdbc40ba.13.png","HVAC APPLICATIONS\nHVAC APPLICATIONS\nThe ceiling radiant system is a hydronic system for room heating and cooling, which \nwas added to the floor version over time; in common it maintains the characteristic \nof having a low temperature difference between the heat transfer fluid and the room \nair.

The system is invisible and uses the entire surface of the ceiling as a \nlarge terminal for the heat exchange (prevailing as radiation). As in the case of the floor \nsystem, the ceiling radiant panels only handle the sensible heat loads; in general, the \nceiling solution offers a higher yield in cooling.\nThe ceiling radiant system shown in the example is used for heating and cooling the \nrooms of a functional building. The distribution is made with a 4-pipe system that make \navailable both fluids at the same time to heat or cool the room.

As an alternative to the diffusers, and in the \nabsence of insulation towards the plenum, the microperforation present on the metal \npanels can be used for the diffusion of renewal and dehumidified air in the rooms.\nControl with Ekinex\nThe room air temperature is controlled in each zone or room by means of an EK-ET2-TP \n(F) multisensor in combination with the EK-HE1-TP actuator-controller (C) that controls \nthe servomotors of the zone valves that regulate the flow of hot or cold heat transfer \nfluid to the series of radiant panels. Thanks to the relative humidity measurement, the \nmultisensor (F) is also able to calculate the dew temperature and send it via bus to \nhigher level systems (BMS) through appropriate gateways. \nWhere necessary, the multisensor (F) can receive a measured temperature value \nfrom an Ekinex® pushbutton (E), normally used to control other bus functions such as \nlighting or shading, to control with a weighted temperature value. This can typically be \ndone in large or high rooms, where the temperature value measured by the multisensor \nis not fully significant of the general temperature conditions in the room.\nThe input interface EK-CD2-TP (H) provides for the acquisition of signals from \ncondensation sensors (5) and window contacts (6).

Two independent thresholds for relative humidity and \nthree thresholds for CO2 and TVOC concentration can be configured. To implement \nautomation logic, combinatorial functions such as AND, OR, NOT and exclusive OR are \navailable; thanks to these functions, it is possible to use the information available on the \nhome automation system to control air renewal according to the actual need (DCV or \nDemand Controlled Ventilation).\nVersions\nEK-ET2-TP with temperature, relative humidity and CO2 eq. measurement\nEK-ES2-TP with temperature, relative humidity, TVOC and CO2 eq. measurement\nLED\nColour and meaning (EK-ES2-TP version)\n1\nwhite (heating mode) or red (heating ON)\n2\nwhite (cooling mode) or blue (cooling ON)\n3\nblue (dehumidification ON)\n4\ngreen (humidification ON)\n5\nred blinking (CO2 eq. concentration > threshold 3)\norange (CO2 eq. concentration between thresholds 2 and 3)\n6\nyellow (CO2 eq. concentration between thresholds 1 and 2)\ngreen (CO2 eq. concentration \u003C threshold 1)\n7\nred blinking lampeggiante (TVOC concentration > threshold 3)\norange (TVOC concentration between thresholds 2 and 3)\n8\nyellow (TVOC concentration between thresholds 1 and 2)\ngreen (TVOC concentration \u003C threshold 1)\n1 \n2 \n3 \n4 \n1 \n2 \n3 \n4 \n5\n6\n7\n8 \n26\n27\n",14,{"image":70,"text":71,"number":72},"\u002Fmedia\u002Fimages\u002Fcd\u002Fc5abf5967dca696a45458fe77a3ccc-26fdbc40ba.15.png","HVAC APPLICATIONS\nHVAC APPLICATIONS\nThe VAV (Variable Air Volume) systems are designed for room ventilation according \nto the actual needs, having inside the appropriate boxes (2) motorized dampers (1)\nthat act as a regulator of the fresh air flow. In combination with the home automation \nsensors installed in the room, the system guarantees high energy efficiency, since the \nroom can be ventilated according to one or more parameters measured in the room. \nThe use of an EK-TM1-TP time digital switch (A), possibly with optional GPS module \n(B), allows not only to define the operating time scheduling for the ventilation system \naccording to the expected occupation of the building, but also advanced functions like, \nfor example, the activation of a washing cycle of the room air before the beginning of \nworking hours. \nThe use of a presence sensor EK-DF2-TP (D) is indicated when you want to make \nan automatic control of simplified type with opening of the damper of the VAV box in \nconditions of occupied room and setting the minimum flow rate to save energy when \nthe room is not occupied. Higher efficiency is achieved by using a multisensor (C) that \ncan adjust the flow rate of incoming air according to the measurement of air quality and \nthe predefined thresholds.\nThe signal of a window contact (5), detected by an input interface EK-CC2-TP (E), allows \nto temporarily deactivate the ventilation so as not to waste unnecessarily energy; the \nreactivation takes place automatically when the window is closed. \nControl based on CO2 or TVOC values\nThe choice of the control parameter depends mainly on the intended use of the rooms. \nWhere the variability in the occupancy rate is very high or unpredictable (such as \nin meeting rooms, classrooms or small commercial environments) CO2 is the most \nused indicator because its concentration is directly related to human activity and, \nin particular, to breathing. Although CO2 is not harmful to human health (except in \nvery high concentrations, which are difficult to achieve), it has a direct impact on the \nconcentration capacity and productivity of the occupants. When the number of people \nin the room is predictable and limited, the detection of volatile organic compounds (or \nTVOC), a set of organic chemicals continuously emitted from furniture, paints, cleaning \nsolvents, adhesives or other synthetic materials due to their high volatility, may be more \nsignificant.\nAir renewal with VAV boxes\nAir extraction \nAir supply\n \nM\nM\n1\n1\n2\n2\n3\n4\n5\nEK-TM1-TP\nDigital time \u002F Astronomical switch\nA\nB\nC\nD\nE\nExample\nEkinex devices\nA) Time \u002F astronomical digital switch EK-TM1-TP \nB) GPS module EK-GPS-1\nC) Multisensor EK-ET2-TP\nD) Presence sensor EK-DF2-TP\nE) Universal interface EK-CC2-TP\nOther system components\n1) KNX servomotor for dumper (not delivered by Ekinex)\n2) VAV (Variable Air Volume) box\n3) Air supply outlet \n4) Air extraction outlet\n5) Window contact\nThe high level of insulation and the high-performance windows and doors used in new \nbuildings or in buildings that have undergone major renovation to meet the energy \nefficiency requirements of EPBD directive (91\u002F2002\u002FEC and following releases) have \ngreatly reduced heat losses to the outside and, at the same time, have in many cases \nmade it necessary to use mechanical ventilation units for air renewal with energy \nrecovery. The manual control of these units alone is inadequate to ensure energy \nefficiency in their operation and even a simple time scheduling is not fully satisfactory. \nAs pointed out by EU Regulations no. 1253 and 1254 of 2014, for these ventilation \nunits it is necessary to use an environmental control by measuring one or more \nparameters to automatically adjust the flow of fresh air to be introduced into the rooms. \nControl with Ekinex\nThe EK-ET2-TP multisensor (D) measures three environmental parameters that are \nrepresentative of the ventilation requirement: the main one is the air quality (as CO2\nconcentration in ppm), together with the relative humidity (in %) and the temperature \n(in °C). Other useful environmental parameters are the detection of the presence or \nmovement of people inside the rooms by means of the EK-DF2-TP sensor (E) or \nsignals due to the activation of other home automation functions, such as lighting \nswitching by means of the pushbutton (F) of 20venti series. The EK-TM1-TP (B) digital \ntime \u002F astronomical switch (B) also provides start \u002F stop command for the ventilation \nsystem according to predefined time scheduling and is constantly synchronised with the \ndate and time by the (optional) GPS module EK-GPS-1 (C).\nThe EK-BO1-TP-RMA interface (A) for RDZ mechanical ventilation units with energy \nrecovery provides bidirectional communication between KNX devices and the control \nboard (2) of the unit. The EK-CC2-TP universal interface (G) acquires signals from \ntraditional components, such as a manual switch for seasonal changeover (3) or a \nwindow contact (4).\nDemand controlled ventilation\nThanks to the many environmental parameters made available by the Ekinex® home \nautomation system, it is possible to carry out ventilation control according to the actual \nneed for air renewal (a strategy known as DCV or Demand Controlled Ventilation). This \nallows to constantly adjust the air flow rate to be introduced into the rooms to the \nreal needs with the aim of maintaining a constantly high air quality, while minimizing \nthe energy consumption. Air quality can typically be controlled by measuring the CO2\nconcentration. With this kind of control, energy savings are twofold: the operating time \nof the fan units is reduced and the flow rate of fresh air to be handled, before release \ninto the rooms, through heating, cooling, humidification and dehumidification processes. \nAir renewal with energy recovery ventilation units\n \n \n \n \nGeneral consensus\n(EK-TM1-TP)\nTemperature\nAir quality\nRelative\nhumidity\nPresence\nof people\nManual\ncontrol\nOther\n(EK-ET2-TP)\n(EK-ET2-TP)\n(EK-ET2-TP)\n(EK-Dx2-TP)\n(EK-E12-TP)\nVentilation\nsystem\nAdditional information from ekinex KNX devices\n(communicating real needs)\nDomotic system (environmental parameters)\nEK-TM1-TP\nDigital time \u002F Astronomical switch\nB\nC\nTVOC\nCO2\ntraffic\nR\nError\nModbus \u002F KNX interface for\nRDZ air handling units\nEK-BO1-TP-RMA\nModbus\nPower\nRX\nTX\ngreen\nred\nA\nB\nKNX\nProgr.\nRS-485 Modbus\nA\nD\nE\nF\nCOMFORT\nOFF\nECONOMY\nBOOST\nG\n3\n4\n1\n2\n5\n6\n8\n7\nExample\n6\n7\n6\n7\n5\n1\n8\nEkinex devices\nA) Modbus \u002F KNX interface for RDZ air renewal units\nB Time \u002F astronomical digital switch EK-TM1-TP \nC) GPS module EK-GPS-1\nD) Multisensor EK-ET2-TP or EK-ES2-TP\nE) Presence sensor EK-DF2-TP\nF) Pushbutton Serie 20venti\nG) Universal interface EK-CC2-TP\nOther components\n1) Mechanical ventilation unit with energy recovery\n2) Control board of RDZ ventilation unit\n3) Two-position switch\n4) Window contact\n5) Fresh air (from outside)\n6) Stale air (from inside)\n7) Pre-heated air (to inside)\n8) Exhaust air (to outside)\n28\n29\n",15,{"image":74,"text":75,"number":76},"\u002Fmedia\u002Fimages\u002Fcd\u002Fc5abf5967dca696a45458fe77a3ccc-26fdbc40ba.16.png","HVAC APPLICATIONS\nHVAC APPLICATIONS\nVariable Refrigerant Flow (VRF) systems are used in the summer and winter air \nconditioning of buildings and in the production of domestic hot water.

This \ncorresponds to the need to make users more aware of their behaviour and to trigger a \nvirtuous process to reduce the waste of resources in buildings. The inspiring principle of \nthe European Union’s measures is that energy efficiency should be equated with a real \nsource of energy; in other words, increased energy efficiency and better management \nof demand should be put on an equal footing with generation capacity.\nAs far as the thermal part is concerned, the measurement of consumption and local \nenergy production is particularly important, since in residential buildings space heating \nand domestic hot water production account on average for about 80% of final energy \nconsumption. \nDirective 2006\u002F32\u002FEC initially identified the widespread use of smart metering \nsystems as an essential action to improve energy efficiency. Directive 2012\u002F27\u002FEU \nthen required that final customers of electricity, natural gas, district heating, district \ncooling and domestic hot water receive individual meters of actual consumption; its \ntransposition by Legislative Decree No. 102 of 2014 led in buildings with centralised \nheating generation (or served by a district heating network) to the installation by the end \nof 2016 of individual meters or heat energy meters. Finally, Directive 2018\u002F2002\u002FEU \nrequires newly installed heat meters and heat cost allocators to be remotely readable \nfrom 2020. By 10 January 2027, already installed meters and heat meters that do not \nhave remote reading capability must also be equipped with remote reading capability \nor replaced with devices that can be read remotely. To this end, it is advantageous to \nexploit the infrastructure of the home automation system, where present, not only for \nits numerous monitoring and visualisation possibilities, but also for its ability to control in \nreal time and intervene on all the system functions that may cause waste.\nConsumption monitoring\nEkinex devices\nA) Electricity meter with KNX communication module EK-MC1-TP\nB) KNX \u002F IP router EK-BC1-TP\nC) Supervision software\nOther system components\n1) Solar panels\n2) Heat meter (solar system)\n3) Hot water storage tank \n4) Thermal energy meter (domestic hot water)\n5) Central heat energy meter (heating\u002Fcooling)\n6) Domestic hot and cold water meters\n7) M-Bus power supply\n8) Photovoltaic solar panels\n9) Photovoltaic inverter\n10) Electricity meter (delivery point)\nExample\n2\n4\n1\nBoiler room\nEK-MC1-TP\nPOWER\nSTATUS\nPROG\nR\nEK-ME1-06T\n3\nA\nReception\nbus\nstatus\ntraffic\nGA\nfunction\nPA\nR EK-BC1-TP\nIP router\nIP\nTP\nB\nRS485\nCO\nCON\nCONTECA\nEASY\nT\nT\nRS485\nEASY\nCONTECA\nEASY\nM07 1259\n07185865\nT\nT\nT\nT\n1\n5\n9\n6\nRS485\nUSB\n5\nRS485\nEASY\nCONTECA\nEASY\nT\nT\n������������������\nUtilities����\n5\nRS485\nEASY\nCONTECA\nEASY\nT\nT\nAFS\nACS\nAFS\nACS\n�������������\n��������������������\nA\n7\n8\n=\n~\n9\n��������������\nEK-MC1-TP\nPOWER\nSTATUS\nPROG\nR\nEK-ME1-06T\n��������������������\n�������\nEK-MC1-TP\nPOWER\nSTATUS\nPROG\nR\nEK-ME1-06T\nEK-MC1-TP\nPOWER\nSTATUS\nPROG\nR\nEK-ME1-06T\nA\nA\n10\n6\n6\nC\n10\nHeating and cooling\n���������\n����������\n�������\nHeating and cooling\n��������������������\n�������\n����������������\n����������\n30\n31\n",16,{"image":78,"text":79,"number":80},"\u002Fmedia\u002Fimages\u002Fcd\u002Fc5abf5967dca696a45458fe77a3ccc-26fdbc40ba.17.png","HVAC APPLICATIONS\nHVAC APPLICATIONS\nControl with home speaker \u002F voice assistants\nIn recent years, voice assistants integrated into home speakers have become firmly \nestablished, not only for interaction with the web, but also as an easy and intuitive \ncontrol interface for a smart building. \nVoice control offers the ability to control several room functions in the most natural and \nimmediate way.

The European Union has drawn attention to the fact that buildings are \nresponsible for 40% of final energy consumption - and 75% of them are still energy \ninefficient - requiring Member States to make a major recovery of efficiency through \nmandatory transposition directives. On the other hand, this action must not decrease \nthe comfort and well-being of the end-users of buildings, also considering the high \nproportion of time spent indoors. The concept of Indoor Environmental Quality (IEQ) \nhas therefore been affirmed, underlining the importance of ensuring high environmental \nquality within confined spaces, together with the recovery of energy efficiency. \nThis is a comprehensive approach in four dimensions:\n- thermo-hygrometric comfort;\n- air quality;\n- visual comfort;\n- acoustic comfort.\nThe first two dimensions are representative of the Indoor Climate Quality (ICQ) and are \ndirectly influenced by the heating, cooling, dehumidification, air renewal and ventilation \nsystems and by the functions carried out by the building automation and control system. \nIn 2008, the IEQ concepts were recognised with the publication of EN 15251 standard, \nwhich was replaced in 2019 by EN 16798-1 standard.\n  \nReferences\nEN 16798-1:2019 Energy performance of buildings.

In moderate thermal rooms these \nparameters do not have an impact on human health.\n- CO2 is mostly produced by breathing people and animals, but it is only harmful above \nvery high concentrations that are usually not reached inside buildings. However, a high \nconcentration of CO2 in confined spaces negatively affects people’s productivity and \ncognitive abilities; this parameter is often used as a reference for evaluating the quality \nof the room air mass.\n- The actual pollutants can instead have consequences on human health; the extent \nvaries and ranges from simple olfactory stress and headaches, through biological \neffects such as irritation and allergic reactions, to serious diseases in case of very \nprolonged exposure. Pollutants can be divided into two categories according to their \norigin: internal or external. Due to the inevitable exchange of air between outside and \ninside, external pollutants are generally also detectable inside. Indoor pollutants are \nnumerous and heterogeneous, but particular attention should be paid to Volatile Organic \nCompounds (VOCs) and airborne dust (PM or Particulate Matter).

Some home automation devices allow this zone to be defined by means of \nfive parameters (minimum and maximum temperature, minimum and maximum relative \nhumidity and absolute humidity), informing system supervision when the combination \nof measured values is outside the comfort zone. \nThe EN ISO 7730 standard offers the design tools to assess not only the overall \ncomfort experienced by occupants of moderate thermal environments using the PMV \n(Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied) indexes, but also \nany local discomfort using four indexes that consider respectively the air currents, the \nvertical air temperature gradient, the temperature, the floor temperature and the radiant \nasymmetry.\nReferences\nEN ISO 7730:2005 Ergonomics of the thermal environment - Analytical determination \nand interpretation of thermal comfort using calculation of the PMV and PPD indices and \nlocal thermal comfort criteria\nThermo-hygrometric comfort\nWhen we talk about air quality, we generally think of the outdoor air, due to polluting \nand climate-altering emissions caused by production activities, vehicle traffic or winter \nheating of buildings. But today we are aware that problems of poor air quality can arise \neven indoors, due to pollutants from both inside and outside the building and by the \nincrease in the concentration of CO2 produced by human presence. \nThis is not to be underestimated, since in Europe, on average, more than 90% of one’s \ntime is spent indoors: in Italy, for example, 55% in the home, 33% in the workplace, \n4% in other environments, while only a residual percentage of time is spent outdoors. \nIn addition, 10 to 20 m³ of air are inhaled every day, depending on age and activity: \nthis corresponds to an air mass that varies between 12 and 24 kg, much greater than \nthat of food and drinking water consumed every day. \nIn this case we are talking about air quality in confined spaces (IAQ, or Indoor Air \nQuality), a topic that has come back in recent years when we began to build and \nrenovate buildings in accordance with the provisions of the law following the directive \non energy performance in buildings (2002\u002F91\u002FEC). With the aim of minimising heat \nloss to the outside, buildings are now strongly insulated and fitted with sealed doors \nand windows; this increases energy efficiency, but still makes them airtight. In these \nconditions, air renewal by manual opening of windows alone is inadequate and people \nare exposed to the risks of increased concentration of slowly but constantly emitted \npollutants from the synthetic products used in the construction sector and from the \nconsumer products present in all buildings. \nIf exposure to pollutants becomes very prolonged over time, the problem is no longer \njust the well-being in confined spaces, but can also seriously affect people’s health. It \nis therefore clear why it is important to take all the necessary precautions to ensure \nhigh air quality.\nSeveral studies show that adequate ventilation in the workplace leads to higher \nproductivity and fewer absences for health reasons. In school environments, high air \nquality helps students to concentrate, while in commercial buildings it makes shopping \ntime more enjoyable. On the other hand, the room ventilation means an energy cost that \ncan become relevant. The control of air renewal by the home automation system makes \nit possible to reach the best compromise between high air quality and high energy \nefficiency. Using home automation for this purpose also means reducing the number of \nsensors to be installed and making multifunctional use of the devices and signal wiring \nalready provided in the building for other functions, such as air conditioning, lighting \nor shading control. \nAir quality\nAir temperature [°C]\nRelative humidity [%]\ncomfortable\ntoo humid\ntoo dry\nmedium \ncomfortable\n12\n14\n16\n18\n20\n22\n24\n26\n28\n0\n10\n20\n30\n40\n50\n60\n70\n80\n90\n100\nBuildings constructed or renovated in accordance with \nthe latest legal requirements offer considerable potential \nfor increasing energy effi ciency, but to fully exploit this \npotential it is necessary to optimise the operation of the \nvarious technical systems. Building automation systems \nprovide for this; the control functions of the heating \nsystem are a fundamental part of it. According to the EN \n15232 standard, during the design phase it is possible \nto evaluate the energy savings obtained by adopting increasing levels of automation and to \nplace the building in one of the four energy effi ciency classes defi ned: from A (more effi cient) \nto D (less effi cient). The functions of HVAC systems contribute signifi cantly to energy \neffi ciency: heating, cooling, ventilation, humidifi cation, dehumidifi cation and production of \nhot water for sanitary use. \nThis European Standard specifies also:\n• a structured list of control, building automation and technical building management \nfunctions which contribute to the energy performance of buildings; functions have \nbeen categorized and structured according to building disciplines and so called \nBuilding automation and control (BAC);\n• a method to define minimum requirements or any specification regarding the \ncontrol, building automation and technical building management functions contributing \nto energy efficiency of a building to be implemented in building of different \ncomplexities;\n• a factor based method to get a first estimation of the effect of these functions on \ntypical buildings types and use profiles;\n• detailed methods to assess the effect of these functions on a given building.\nClass A: includes buildings with high energy performance, equipped with control and \nautomation systems (BACS) and technical plant management (TBM) characterized by \nhigh levels of accuracy and completeness of automatic control.\nClass B: this includes energy advanced buildings, with control and automation systems \n(BACS) and technical plant management systems (TBM) that allow centralised control.\nClass C: includes standard buildings from the energy point of view, equipped with control \nand automation systems (BACS) with basic functionality. It is also the class used as a \nreference for calculating effi ciency factors.\nClass D: includes buildings that are not energy effi cient and have only traditional technical \nsystems, without any automation.\nThe Italian Interministerial Decree of 26 June 2015 (“Minimum Requirements” decree) \nprescribes for non-residential buildings a minimum level of automation corresponding \nto Class B for the control, regulation and management of building and heating system \ntechnologies (BACS).\nReferences\nEN 15232-1:2017 Energy Performance of Buildings - Energy performance of \nbuildings - Part 1: Impact of Building Automation, Controls and Building Management\nEnergy classifi cation of buildings (EN 15232)\nIn recent years, the interest in building control and automation systems has considerably \nincreased: now they are considered by directives and standards as a fundamental \nelement to achieve the ambitious energy efficiency objectives of the European Union, \nwhile maintaining a high level of comfort in all situations. \nThe energy efficiency and performance of buildings has been a focus of attention for \ndesigners, builders and end-users since 2002, when Directive 2002\u002F91\u002FEC on the \nenergy performance of buildings was published. The second revision of this Directive \n(2018\u002F844\u002FEU) aims at spreading intelligent technologies as much as possible inside \nbuildings. This latest version is therefore particularly important for the sector of home \nautomation and building automation, as it actively promotes the widespread use of \nthese systems. The directive requires that non-residential buildings with heating (or \nheating and ventilation combined) systems with an effective rated output of more \nthan 290 kW must be equipped with automation and control systems by 2025, while \nfor residential buildings there is a requirement for continuous electronic monitoring \nto measure the efficiency of the systems and inform owners (or administrators) if \nsignificant efficiency drops or need for maintenance occur. To these must be added \neffective control capabilities to optimize power generation, distribution, storage and \nconsumption. \nThe Directive also introduces the Smart Readiness Indicator (SRI), which provides \nsummary information on the intelligence of the building to all interested parties: end-\nusers, designers, builders, investors, operators and service providers. The indicator \nsummarises the ability of the building to maintain energy efficiency and its functioning \nby adapting its energy consumption using, for example, available renewable sources. In \naddition, the building must adapt its operation to the needs of end-users, ensuring ease \nof use, the thermo-hygrothermal comfort of the interior and the ability to communicate \ndata on energy consumption.\nThe Directive also recognises that building automation and monitoring is a cost-effective \nalternative to technical inspections, particularly in large non-residential buildings and \ncondominiums.\nThe way in which certain articles of Directive 2018\u002F844\u002FEU are implemented has \nbeen described in more detail in the recommendations subsequently drawn up by the \nEuropean Commission, which serve to support Member States in preparing national \ntransposition measures. The recommendations definitively recognise that the use \nof intelligent systems in buildings is essential to achieve the targets set for energy \nefficiency by 2030 and decarbonisation of the building stock by 2050.\nReferences\nDirective 2018\u002F844 amending Directive 2010\u002F31\u002FEU on the energy performance of \nbuildings and Directive 2012\u002F27\u002FEU on energy efficiency\nRecommendation 2019\u002F786 on the renovation of buildings\nRecommendation 2019\u002F1019 on the modernisation of buildings\nBuilding automation and European directives\nA\nB\nC\nD\n36\n37\n",19,{"image":90,"text":91,"number":92},"\u002Fmedia\u002Fimages\u002Fcd\u002Fc5abf5967dca696a45458fe77a3ccc-26fdbc40ba.20.png","HVAC APPLICATIONS\nIn 2016, the CTI (Italian Thermotechnical Committee) published the technical report UNI \nTR 11619, which defines the normative references and the calculation methodology \nfor determining the energy efficiency index of radiant systems for heating and cooling \nwith low temperature difference, in the floor, wall and ceiling versions in compliance \nwith the EN 1264 standard, combined with strategies for regulating, balancing and \ncontrolling the circulation pumps.  \nThe index defined by the technical report considers the performance of:\n- emission of the radiant system (ηe)\n- thermoregulation of the ambient air and the heat transfer fluid (ηrg)\n- balancing of circuits (ηbal)\n- circolating pumps (ηcirc)\nRSEE index\nThe energy efficiency index, called RSEE (Radiant System Energy Efficiency), is \nexpressed as a product of the yields of the various systems and components of the \nsystem:  \nRSEE = ηe ∙ ηrg ∙ ηbal ∙ ηcirc\nThe overall efficiency of a system can vary considerably: the most significant factor \nis the choice of temperature control devices (the values vary from 0.91 to 0.99). \nηrg represents the control efficiency and is directly influenced by the design choices \n(such as the independent control for zones or single rooms, the climatic compensation \nfunction) and by the configuration of the devices (ON \u002F OFF or PI proportional-integral \ncontrol). Depending on the value of the index, the radiant system can be placed in 5 \nclasses, from AAA (> 0.98) to D (\u003C 0.88).\nSimulations (source: UNI \u002F TR 11619)\nAs time goes by, more and more projects of buildings are submitted to sustainability \ncertification. The concept of “sustainability”, which is now common in many sectors, \nwas defined in the “Our Common Future” report (known also as Brundtland Report) \npublished in 1987 by the World Commission on Environment and Development. \nSustainable development is a process that ensures “that the needs of the present \ngeneration are met without compromising the ability of future generations to meet \ntheir own needs”. In this sense, sustainability must ensure compatibility between \ndevelopment and environmental protection. \nBuildings are major consumers of resources and therefore this principle also applies \nto them; for this reason, certification schemes have been developed over the years to \ncertify their sustainability. Building projects that are subject to sustainability certification \ncan receive points in different categories: in the case of LEED* (Leadership in Energy \nand Environmental Design), for example, they include location and transport, site, water \nefficiency, energy and atmosphere, materials and resources, indoor environmental \nquality, innovation and more. Based on the number of credits obtained, a project \nobtains one of the levels of assessment provided for in the certification scheme. \nBuilding automation plays a very important role in achieving sustainability certification. \nThe use of the KNX system can contribute to obtaining up to 54 credits** out of a \nmaximum of 110 provided for by LEED certification. 80% of the credits to which KNX \ncontributes relate to three LEED categories: water efficiency, energy and atmosphere, \nand indoor environmental quality. \n*) Developed by U.S. Green Building Council (USGBC)\n**) KNX for LEED, 2013, Jesús Arias García, Miguel Ángel Jiménez Ibiricu, KNX Association cvba (Bruxelles)\nIn order to better define the concept of sustainability with reference to the construction \nsector, the ISO 15392 standard was also published in 2008, which sets out sustainability \nobjectives and general principles. The standard defines sustainability as “the condition \nin which the components of the ecosystem and their functions are maintained for the \npresent and future generations”. To complete ISO 15392, the technical specification \nISO\u002FTS 12720 has been published, which provides guidelines for its application. In \naddition, ISO 21931-1 identifies and describes the factors to be considered when \nassessing the environmental performance of new or existing buildings in the design, \nconstruction, operation, maintenance, renovation and decommissioning phases.\nReferences \nISO 15392:2008 Sustainability in building construction - General principles\nISO\u002FTS 12720:2014 Sustainability in buildings and civil engineering works - Guidelines \non the application of the general principles in ISO 15392\nISO 21931-1:2010 Sustainability in building construction - Framework for methods of \nassessment of the environmental performance of construction works - Part 1: Buildings. \nSustainability certifi cation\nEnergy classifi cation of radiant systems (UNI \u002F TR 11619)\nControl\nDescription\nηrg\nOnly zone \nON \u002F OFF\nThermostat in living room, setpoint temperature: 20°C ± 1°C.
