Zero Energy Building Features
The Zero Energy Building concept of this building applied both combination of advance and currently available Energy Efficiency, EE and Renewable Energy, RE technology integrated into the building early during design concept stage. By lowering and keeping the buildings energy load as low as possible through the implementation of these energy efficient elements, less energy requirement for energy generation by the BIPV system is needed.
As the result, this will not only reduce the building's' energy load, but also reduce the cost for BIPV installation indirectly. In the ZEO building, BIPV was the RE technology of choice since it can be integrated as part of the building and does not requires batteries system if compared with standalone PV system.
Energy Efficient (EE) Technology Used
- Daylighting (almost 100%)- EE lighting with T5 tubes and LED task lights
- Double glazing windows. The lower windows or called as Vision Windows -> (heat and accoustic insulation). 50 percent daylight penetration.
- Double glazing windows with integrated blinds. The upper windows or called as Daylight Windows -> (heat, glare and accoustic insulation). 70 percent daylight penetration.
- Mirror Lightshelf, Rooflight and Skylight system (also BIPV Package C) respectively.
- Roof and wall Insulation (reduce outside heat gain)
Active System.
- EE office equipment (laptops, LCD monitors, networked printers)
- EE IT Network & server room (75% wireless network)
- EE air conditioning & ventilation
- Floor slab cooling (For radiant cooling and thermal storage)
- Chilled Metal Ceillings (For radiant cooling)
- River Roof (For Condenser/ Heat Sink side)
- Ice storage cooling system (minimised air-cond chillers capacity)
- Controls & Sensors (VSDs, VAVs, CO2, BMS / Energy monitoring)
Renewable Energy (RE) Technology Used
