Bayer has opened its first emissions-neutral office building in Asia, in Greater Noida, near New Delhi, India. The building, approximately 1,000 m2 in size and accommodating around 40 workstations, draws 100 % of its electricity from a photovoltaic plant and needs some 50 % less power than comparable buildings in the region. It cost around EUR 5 million to build and is a project for Bayer’s EcoCommercial Building (ECB) program, a specialist global network for sustainable construction.
The two-story, cube-shaped building was designed using extensive computer simulations and was adapted effectively to suit the local sub-tropical climate. The building is aligned according to the path of the sun. The walls, roof and floors are insulated with polyisocyanurate (PIR) rigid foam to keep the heat out. Over its service life, this material helps save some 70 times as much energy as is needed to produce it. The ratio of windows to walls has been calculated with great precision, with transparent surfaces making up a good third of the total area.
Energy consumption for heating, cooling, ventilation and lighting is covered in full by renewable energy. A photovoltaic system on the roof generates some 120,000 kWh of renewable electricity each year. That is equivalent to a reduction of approximately 108,000 kg of CO2 emissions.
Taken over the year as a whole, the building is CO2-neutral.
Bayer has previously built a climate-neutral company child daycare center at its Monheim site in Germany and an energy-optimized office building in Belgium.
