Leverkusen, Germany - Bayer MaterialScience says its "emissions-neutral" office building in Greater Noida, India, has generated a positive energy balance in the year since the building was inaugurated.
A photovoltaic system installed on the roof helped generate 72 000 kilowatt hours (kWh) of energy, whereas the building used nearly 64 000 kWh over the same period, BMS said in an 8 Feb news release. The net result is a surplus of more than 8000 kWh.
"The building is designed to use 50 percent less electricity than comparable buildings in our region," said Ram Sai Yelamanchili, head of Bayer MaterialScience's EcoCommercial Building programme in India.
The ECB programme's objective is to support the construction industry with the planning and erection of particularly energy-efficient buildings.
"The building meets 100 percent of its energy needs via the photovoltaic system on the roof, which is aligned with the path of the sun. This enabled us to avoid the emission of 67 tonnes of carbon dioxide last year, which corresponds to the CO2 emissions of around 20 vehicles," added Yelamanchili.
The 900 sq.m two-storey building was designed and optimised for the region's sub-tropical climate on the basis of comprehensive computer simulations. Polyisocyanurate thermal insulation shields the building envelope against the heat, reducing the amount of energy required for air conditioning, Bayer said.
