Where are efficient houses located in my vicinity? What savings were achieved through which measures and which materials? Which architect offers such services? Anyone considering an energy-efficient refurbishment or constructing an energy-efficient new building will certainly have a lot of questions. dena's Efficient House Database makes successful examples visible. It contains more than 1,000 buildings that are each presented on their own page with numerous images and facts. Many profiles also indicate which experts were involved. An entry in the database is possible with the consent of the owner for all exemplary buildings, and is free of charge. The requirement is that they fulfil the KfW efficient house standard: Refurbished buildings need to satisfy at least the efficient house 115 standard, and new buildings at least the efficient house 70 standard.
The database compiles successful examples of energy-efficient construction and refurbishment, and makes them visible. This results in a unique collection of efficient houses which is expected to continue to grow in future. Private clients, but also municipalities and public institutions, can inform themselves and be inspired. For planners and architects, it offers a platform for them to present their own work. Politicians and association members can find out how many efficient houses already exist in their local community.
