Quality control of Stuttgart's retrofit standard realised by the city's energy consultancy office

The City of STUTTGART's RETROFIT STANDARD comprises various steps to achieve the energy-efficient retrofit of both residential and non-residential buildings. This includes the construction supervision, for which the City's Energy Consultancy Office (EBZ) provides qualified experts. In this process, mainly the interfaces between the different trades/works are checked and documented. Moreover, EBZ-trained craftsmen are introduced who are able to install state-of-the-art energy saving measures according to the respective manufacturers' instructions. This ensures high quality of implementation and durable buildings.
