Emissions-neutral office building – A first of its kind in India

Posted on March 4, 2011 by

Bayer has recently unveiled its first emissions-neutral office building in Asia. This is a part of their systematically established group- wide sustainability program. The building in Greater Noida, near New Delhi will house Bayer MaterialScience’s office. The building will draw 100 percent of its electricity requirement from a PV plant. The building at the same time needs 50 percent less power than comparable buildings in the region. Bayer has a specialist global network for sustainable construction by the name EcoCommercial Building (ECB) program. This project will become a significant reference point for the ECB program.

Dr. Wolfgang Plischke, member of the Bayer AG Board of Management responsible for Innovation, Technology and Environment and for the Asia-Pacific region says “Our new office building represents the link between innovation and sustainability. We want to use our skills and products in the field of high-quality materials to boost energy efficiency in buildings, as this approach offers enormous potential for cutting CO2 emissions.” Energy consumption in buildings accounts for around 30 percent of CO2 emissions. “That is why we will continue to expand the EcoCommercial Building program as part of our sustainability strategy – both in Asia and worldwide.”

The earlier energy efficiency projects operationalized by Bayer include approaches such as combining efficient insulation with renewable energies .These as a combination help to dramatically reduce a building’s energy consumption and therefore its CO2 emissions. Such projects have been in the developed countries such as Germany and Belgium. The Noida project shows that the concept can also be applied in sub-tropical climates. While maintaining constant and comfortable temperatures is objective in both the places, building insulation in the temperate European climate zone is used to protect against cold, while in countries such as India is to protect against heat.

The said building costed around EUR 5 million to build. On the emission front, over the year as a whole, the building is CO2-neutral. The energy consumption for heating, cooling, ventilation and lighting is covered in full by renewable energy. The PV systems installed on the roof generates more than 110,000 units (kWh) of renewable electricity each year. The equivalent reduction of CO2 is more than 100 tonnes of of CO2 emissions. One of the key elements of insulation is the polyisocyanurate (PIR) rigid foam to keep the heat out. Highly efficient air-conditioning and lighting systems used in the building help reduce the overall consumption. It will be worthwhile to see when Indian players target to build ’emissions neutral’ building.
