Redesign of a 1970's multifamily home in Bonn, Germany.
The goal of this work is to create an energy efficient architecture that reduces energy consumption up to 50%. Passive as well as active measures are combined to reduce the overall energy consumption and to improve living comfort.
The technical components correspond to a redesign of the facades as well as a refined organization of the individual unit floor plans and their relationship between inside and outside spaces. Two maisonette appartments are introduced on the lower floors; thus creating a new connection between the garden and the existing building with its increased density.
Greenpeace informs us that a residential building built in Germany in the 1970's typically requires 12 to 15 liters of oil per square meter for heating and warm water. In 2003, a standard family home still requires 9 liters. In the same period, a residential building with Minergie-P-Standard requires 3 liters and a Passive House as little as 1.5 liters.
If as of the year 2012, all newly built as well as renovated residential buildings would be designed according to the Minergie-P-Standard, energy consumption could be reduced for 30% until 2035 and up to 50% until 2050.
It is time to act now, everybody can save energy and help reduce global warming.
