1.1.2 Seal air leaks located in all cavities present in the building Description Air leaks can be located in all cavities present in the building. It is not simple to find all points of air infiltration, which are not limited to doors or windows, so sometimes it can be necessary to carry [...]
1.1.3 Close windows and doors when HVAC systems are operating Description Make sure windows or doors are not open unnecessarily, especially when heating, cooling or air conditioning systems are operating. To ventilate the room it is sufficient to have the window open for 10 minutes. In addition, keep it opened for longer [...]
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 [...]
1.2.4 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 [...]
1.2.12 Place the condenser unit in a ventilated area without solar radiation Description If possible locate the condenser unit in an area of the building with shade, that it is not blocked by fences, shrubs and other buildings, or any other obstruction around about 50 cm from the unit. The unit [...]
1.2.19 Cleaning heat exchangers of chillerssent in the building Description HVAC heat exchangers are critical to resident’s comfort in the building. Regularly scheduled heater exchanger cleanings will maintain clean waterside surfaces and ensure superb operation and efficiency. Benefits Reduce heat losses and air infiltration Decrease [...]
1.2.21 Installation of motion sensors for HVAC systems Description As part of a HVAC energy management system, occupancy sensors enable facility managers to automatically control HVAC operation based on room occupancy. If the room is physically occupied, then the system will allow occupants to control the climate. Once a room is [...]
1.2.22 Installation of humidity sensors Description A humidity sensor and fan control detects excess humidity in a room and automatically activates the ventilation fan to reduce excess condensation. The device features an easily adjustable setting for sensor sensitivity, humidity level and automatic time out which can be set to meet the [...]
