For the construction or conversion of residential or non-residential buildings, a proof of energy-efficiency is required as part of the application for approval. An essential criterion is primary energy consumption. In addition to the energy efficiency of the building envelope itself, engineering system parameters also play a role. By opting for renewable energies and premium systems engineering, any shortcomings in the building envelope can be compensated and vice-versa.
Even if the approach may seem conservative at first sight, since the building itself will outlive its technical systems, we recommend opting for a high-quality envelope.
Besides energy-conservation documentation and energy certificates, our office provides calculations to avoid potential surface and other condensation as well as thermal simulations for rooms and buildings with a high solar energy input.
