The carbon footprint is three times lower than that imposed by current Danish regulations. This is a successful bet by Velux, roof window specialist and Effekt Architects, through 7 models of wooden houses visible in Copenhagen entitled Living Places: 5 open prototypes and two closed model houses, one with a timber frame and one made of cross-laminated timber. The carbon emissions of a Living Places wooden house are 3.8 kilograms of C02 per square meter per year, compared to just over 11 kilograms of C02 per square meter per year in a traditional Danish house. If all single-family homes were built according to the Living Places model, one million tons of C02 could be saved every year, knowing that the construction industry accounts for 1/3 of the world's energy consumption and C02 emissions. Living Places thus has the lowest carbon footprint in Denmark.
