Project description
The existing building has three storeys and is located in Neufahrn near Freising. Heat generation was designed using renewable energy plus electric back-up. The heat was delivered to the individual rooms via underfloor heating. Following coordination with the municipal drainage authority, the drainage design for rainwater and foul water was prepared. The entire house was designed to HEA equipment level 2 (RAL-RG 678). At the clients' request, the installation was drawn individually unit by unit. The steps in the stairwell were built with integrated lighting. In addition, a photovoltaic system was designed to generate electricity efficiently.

Grandfathering provisions combined with the requirement for state-of-the-art technology
