„The residential house was already a passive house at the beginning of the project. This means that the structure of the building envelope stores the heat inside the building and thus requires little additional heating. Our plan was that the family could generate their own electricity by installing the photovoltaic system and thus become even more independent of their energy supplier,“ says Kim Schneck, Project Manager Energy Systems, HUMMEL Systemhaus.

„This project demonstrates the proven modular principle of K2 Systems, which enables simple, cost-effective and fast installation. Despite the different covering of pantiles and sheet metal dormers, the same mounting rails and the same module clamps are used. The reliable CrossHook 3S roof hook was used for the pantiles and the standing seam clamp for the sheet metal dormers,“ says Stephan Klopfer, K2 Systems project manager.

Due to the compatibility with a few basic components (e.g. universal clamp OneMid and rail SingleRail/SolidRail) and a matching roof fastener, different applications can be realized with relatively little effort and extremely quickly. Overall, fewer different materials are required on the construction site and in the warehouse, resulting in lower costs for transport and storage. Likewise, the employees are more experienced in setting up and thus faster in the design of a system during assembly.
