GEG in transition - planning security through building physics

Energy-efficient building design with thermal image analysis, Ingenieurteam Trebes GmbH & Co. KG.

The current debate in the Bundestag regarding the Building Energy Act (GEG) and the draft bill under consideration makes it clear once again: Good planning not only makes buildings energy-efficient, but also economically viable and livable in the long term—whether in new construction or existing buildings.

Particularly against the backdrop of increasing requirements and statutory regulations, planning reliability through sound expertise in building physics and energy efficiency is becoming a decisive factor.

We prepare thermal insulation certificates and develop individual refurbishment roadmaps (iSFP) as well as holistic refurbishment concepts. As energy efficiency experts, we provide support for KfW and BAFA funding programs - especially in the refurbishment of existing buildings. In addition to specialist planning, we also support projects during implementation, thus ensuring consistent quality.

We offer special added value in particular through:

Thermal building simulation for realistic evaluation of comfort and thermal insulation in summer

Life cycle analysis (LCA) and life cycle assessment for a holistic view of sustainability and economic efficiency

Thanks to the close cooperation between structural design and building physics, we often support projects holistically and practically from the early planning phases onwards.

The aim: economical, eligible and sustainable solutions - with maximum planning security right from the start.
