In 2017 we set a goal for energy reduction in our 400 meter office space. We lowered the ceiling height by installing a cassetted false ceiling without affecting the aesthetics or reducing climate comfort. We also installed fibrous insulation above the ceiling to further reduce heat loss.
These efforts reduced the energy consumption in our office by 37.000 kWh a year. By comparison this reduction equals the yearly consumption of natural gas in 4 households or 7500 kg of carbon dioxide. The same amount of carbon dioxide can be sequestered in two Oak trees over their 80 year lifespan.
