“When building energy-neutral homes, all stakeholders must simultaneously harness their individual disciplines in order to achieve the ultimate product. Installation consultant, Breman Hasselt, was directly involved in the project for precisely this reason. With traditional building projects, you work step by step. First the architect does his job, followed by the consultant and then the contractor, etc. The installations are a sort of add-on, so to speak. With energy-neutral construction, the shell and installation requirements determine the actual design, and everything has to be integrated with this.”
