Preserve the fabric. Gain efficiency.
Refurbishment of residential and commercial buildings with a focus on energy efficiency, heritage compatibility and eligibility for BEG and KfW funding.
Six levers for a future-ready building.
We see the building as a system — envelope, building services and use. From that we develop economically viable refurbishment roadmaps.
Insulation
External walls, roof, top floor slab, basement ceiling — we calculate the most economically and energetically sensible solution per component.
Windows and doors
Replacement or refurbishment. For heritage buildings we work with interior insulation and heritage-compatible glazing.
Heating system
Heat pumps, solar thermal, hybrid systems, district heating — sized to suit building condition and funding landscape.
Renewable energy
Photovoltaics with storage, solar thermal, tenant-electricity schemes. We evaluate viability and funding options.
BEG and KfW funding
Eligible refurbishment under BEG single measures or full retrofit to Efficiency House. We handle the application.
Heritage-sensitive retrofit
Preserving the substance, careful energy modernisation, coordination with the heritage authority. Focus on Berlin.
