Sustainability isn't marketing. It's how we work.
For us green building is a consequence of common sense — not a fashionable label. Here's how we approach it.
Energy-efficient buildings
We target energy classes A0, A1 and A+. Where it makes sense, we design buildings with on-site energy production, heat recovery and heat pumps. Lower operating cost = higher property value and better tenant comfort.
Natural materials
Wood, stone, clay, natural insulation — materials kept as close to nature as possible. Where it pays off structurally and economically, we prefer materials that will still look and perform well decades later.
Green vehicle fleet
All our passenger cars are already fully electric (BEV only), and the majority of our vans too. We're finishing the electrification of the rest of the company fleet.
Tree-planting initiative
For the projects we deliver, we give back to nature — through regular tree planting in the regions where we operate. Not as a symbol, but measurably.
In practice this means
- Photovoltaics and battery storage on new projects
- Air / water heat pumps instead of conventional boilers
- Heat recovery and managed ventilation for air quality and energy savings
- Hot water storage from surplus on-site electricity
- Rainwater capture for WC flushing and technical uses
- Smart metering and intelligent zone control
- EV chargers as part of the project, not a retrofit
- Elimination of single-use packaging and toiletries in our operations
The principles behind every decision
Savings first, then technology
The best kilowatt-hour is the one we don't need to produce. Before adding technology, we deal with the building envelope, insulation and thermal bridges.
Economic logic
A sustainable solution must also make economic sense for the building's owner. Otherwise it won't survive in real operation.
Materials that age well
Wood, stone and clay often look better after 20 years than on the day of completion. Plastic and cheap surface finishes do not.
