Astrid Müller | Energy concept Aachen Richtericher Dell

An ecologically and economically sound urban planning concept was developed for this project in order to set conditions related to planning law and contractual obligations that would ensure energy-efficient construction. Energy standards, energy supply variants, and building envelopes were analyzed for relevant building types.

Peter Lückerath | Interface management in Passive House buildings

Excellent cooperation between designers and tradespeople is essential for Passive House, more so than for all previous construction standards. To this end, the City of Geldern and the Environmental Center within the Düsseldorf Chamber of Small Industries and Skilled Trades worked with partners to develop a short course on "Interface management in Passive House buildings."

Ingo Höffle | Integrated design and cost-effectiveness of Passive House office buildings

The task the investor set forth was to build an office building to the Passive House Standard, rather than the EnEV standard, at a maximum cost premium of 1% over EnEV. To achieve this, every design issue had to be fundamentally questioned and optimized, which led to intense interaction among everyone involved in the planning and improved the overall quality of the building.
