One of the very few net-zero (site) energy buildings worldwide, the SunCarrier Omega Net-Zero Energy Building has been operational for a year. The facility was designed and constructed with a focus on five key areas of building sustainability:
Rationalizing energy usage and generation is one of the key features of this facility. Extensive use of daylighting, daylight sensors and occupancy sensors determining the switching on and off of lights, use of low consumption-
To implement supply-side energy sustainability practices, the SunCarrier Omega building has an integrated sun-tracking solar photovoltaic generator, the SunCarrier, coupled with large capacity energy storage and management system, the vanadium redox flow batteries, the Cellcube. This generates, stores and supplies the total electricity required by the building.
The relatively scarce water recourse has been marshaled carefully. A 100% rain-water harvesting system ensures that all the rainwater is trapped and utilized. Sensor-based low-flow water dispensers and controlled-discharge toilets help conserve water, and in-house waste water treatment facility ensures proper reuse of water.
Indoor Air and Environmental Quality
Improving the quality of indoor air and the work environment has a direct impact on the health and productivity of building occupants. Highly efficient, low-noise air-conditioners have been installed at SunCarrier Omega, which uses ozone friendly refrigerant, HFC R 410, with VRV with remote sensors for each indoor unit to optimize energy consumption. Use of carbon dioxide sensors, coupled with a building automation system, ensures that adequate ventilation is maintained automatically, and that carbon dioxide levels in the building are well within the safe limits.
The design of the building site and its maintenance and management plan for its exterior are important components of this sustainable site. Adequate paving and landscaping with an extensive use of native species supports local habitat, and prevents air-pollution, soil erosion and water sedimentation. Reflective roofs and double-glazed glass walls ensure proper thermal insulation.
Materials and Construction
Recycling and reuse are essential elements of sustainable design adopted wherein the grounds and roads were paved with high recycle content pavers and the broken bricks and mortar leftovers from the construction of the building. The building material, itself, has a large local content. Moreover, the ergonomic furniture used is made of wood from specially grown trees (rapidly renewable material) and the wood used in the building is according to FSC guidelines. The adhesives used release no harmful fumes.
Energy is a vital ingredient for the growth and development of any economy. India suffers a power deficit of about 25%, which seriously impairs the ability of its citizens to contribute to its economy and welfare. Innovative deployment of technologies, as seen at the SunCarrier Omega NZEB, helps create proof-points of feasible, robust and demonstrable application of appropriate technologies that create sustainable energy sources, and combat environmental degradation.
