Energy-optimised building construction

Energy-optimised construction requires consideration of numerous aspects relating to the shape and orientation of the building, thermal insulation and avoidance of thermal bridges in the building envelope, as well as their airtightness, and also includes the use of controlled ventilation with heat recovery and the particularly efficient heat and power generation technologies that use energy sources that are as regenerative as possible. Thanks to legal requirements, energy-saving construction is a matter of course today. In research projects we deal with ambitious energy concepts and demonstration projects, whereby we are always particularly interested in the area of ​​conflict between energy saving and user acceptance.

However, the focus of energy optimisation in building planning is expanding more and more: on the one hand, the neighborhood scale has to be increasingly taken into account, on the other hand, the sole consideration of the operating phase does not meet the requirement of an energetic evaluation, a necessary extension offers consideration of the resource-efficient building life cycle in understanding of circular value creation. When working on the differently addressed questions of energy-optimised construction, we use various multi-dimensional, stationary or dynamic component, room and building simulation programs that evaluate variants, e.g. with regard to energy and resource requirements, user comfort and costs for new construction and renovation projects.
