1.2.1 Turning off air conditioning systems when rooms are empty Description When leaving the room, even if it is for a short time, the air conditioning should be turned off. If possible, turn off the air conditioning 20 minutes before leaving, the air will stay cool during this time and there will [...]
1.2.2 Upgrade and maintain the filters of the HVAC system Description Air filters are used to reduce the amount of dust that reaches the wet coils, keeping the HVAC system clean. Dust can make mold to grow on the wet coils and ducts and can reduce the efficiency of the coils. Clogged [...]
1.1.3 Adjust the temperature of the thermostat properly Description Each degree the thermostat is raised above 21° (recommended set point for winter) implies an unnecessary waste of energy of up to 6-8%. While in summer, each degree below 25° (recommended set point for summer) implies an overconsumption of around 6-8%. [...]
1.2.4 Adding or repairing HVAC distribution system insulation Description A correct thermal insulation of HVAC distribution ducts and pipes (including corners) reduces energy losses in distribution and improves the performance of the systems since the equipment works with fluids at temperatures close to the design temperature. Benefits The [...]
1.2.5 Verify the appropiate operation of timers of the ventilation system Description Verify the correct operation of timers in terms of control system depending on the level of occupation of the building. For example: stop during evenings and holidays, change the mode of operation depending on the occupation level and change the [...]
1.2.6 Use of free-cooling Description Free cooling consists in using the outside air cooling capacity to renew and cool the inside air of a room, reducing the energy consumption of the cooling equipment. As consequence, the system only switches on extraction and air conditioning fans, avoiding starting up the compressor of the [...]
1.2.7 Analysis of the combustion and maintenance of heating boilers Description The efficiency of the combustion of a heating boiler is defined by the air-fuel ratio. This ratio is fitted in the regular maintenance of boilers through the adjustment and cleaning of the burners. It is necessary to perform fume analysis periodically [...]
1.2.8 Replacement of the refrigerants fluids in heating and cooling equipment Description Refrigerants are fluids used for exchanges of energy in refrigeration systems. This measure consists in the replacement of the current refrigerant of the air conditioning equipment by a new refrigerant based on HydroCarbons (HCs) which is manufactured based on natural [...]
1.2.9 Adding or repairing boilers insulation Description Insulation of boilers is necessary to protect people against contact with hot surfaces and to ensure an acceptable working temperature in the boiler room. Insulation of boilers is a very efficient way to keep water hotter for longer, especially if the equipment is exposed to [...]
1.2.10 Proper operation of the regulatory systems of the temperature of the heating and cooling equipment Description A control system is a device or set of devices aimed at maintaining a variable at a certain value, or between certain limits set previously. This measure consists in the proper operation of one [...]
