German Demo

The project is located in Ostfildern near Stuttgart. At an altitude of approx. 410 m above sea level the climate is classified as warm and temperate. Ostfildern is a city with a lot of precipitation. The annual average temperature in Osfildern is around 10 °C. The annual rainfall is around 877 mm, and the climate is classified as continental.

The demo consists of a single building owned by Wohnbau Studio GmbH (private real estate). With a mix of different floor plans and sizes, an attempt is made to appeal to a wide range of prospective tenants. The residential units will be realized as rental apartments. A large part of the lighting design will be pre-installed on-site in order to ensure energy-efficient lighting. The kitchens are also made available to future tenants, including energy-saving appliances.

A “power-saving switch” in the entrance area enables the tenant to switch off all secret stand-by electricity consumers centrally when leaving the apartment.
