Buildings or developments that are verified and certified as “net zero operational energy and/or carbon.” The building should demonstrate the highest levels of energy efficiency with the use of either renewables generated onsite or renewable energy procured offsite.
The office is served by a Daikin Heat Recovery VRV system which is comprised of 11 fan coil units and 2 heat recovery VRV heat pumps. Ventilation is provided to the office by a dedicated outside air fan. Each zone has a schedule depending on operations. Only a portion of the building is utilized 24 hours a day. The garage is unconditioned.
Ventilation air is provided to the office by a dedicated outside air fan with variable speed drive. Ventilation air is filtered, but not conditioned. The air is ducted directly to a mixing box on the intake side of each fan coil unit.
A combination of LED lighting and sky light tubes (Solatube 750 DS) are used for lighting the office. Occupancy sensors are located in every room and are connected to lighting control system, which varies the intensity of lights and light switches if needed.
The building occupants were engaged in a series of meetings to make them aware of the strategies being used to improve the performance of the building. it was important to inform them why these changes were being made and ensure that the changes would not adversely effect the operations of this critical facility.
