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 [...]
1.2.23 Installation of an efficient destratification fan system Description Thermal stratification is caused by hot air rising up to the ceiling or roof space because it is lighter than the surrounding cooler air. The same applies to cool air falling to the floor as it is heavier than the surrounding warmer air. [...]
1.3.5 Installation of a timer for the DHW recirculation pump Description It is recommended to install a timer that disconnects the recirculation pump during the hours in which there is no demand of DHW in the building. Benefits In addition to saving energy, the lifespan of the [...]
1.3.6 Installation of a timer for the DHW boiler Description The measure consists in installing a timer (digital or analogic) which turns off the boiler when there is no demand of DHW (e.g. in residential buildings during the night there is no relevant demand of DHW). Benefits [...]
1.3.7 Installation of mixing valves in the outlet of the DHW tank Description A thermostatic mixing valve mixes cold and hot water, generally with a temperature differential of at least 7°C, in order to obtain mixed water at a stabilized temperature, avoiding in this way losses of hot water while adjusting the [...]
1.4.1 Change to task lighting method when required Description The measure proposes the installation of task lighting to give the possibility of concentrating light only in working areas or, in general, where and when it is needed through the combination with general lighting. Benefits In offices, energy [...]
1.4.2 Change to accent lighting when required Description The measure proposes the installation of accent lighting to provide concentrated light on areas with specific requirements of luminosity. Benefits Important energy savings can be achieved since the light is just concentrated where and when is needed Increase [...]
1.4.5 Reduce the number of luminaires Description The measure consists in removing luminaires in spaces where the light levels are higher than the acceptable working lighting level and the entire luminaire could be removed. Benefits The number of luminaires can be reduced and thus their associated energy [...]
1.4.9 Programming different scenarios for the same place Description If different activities (e.g. screening, meeting) with different required lighting levels are developed in the same space (e.g. in a conference room, classroom), it shall be given the possibility of adapting easily the illuminance levels to the activity through switches or touchpad controls [...]
