  • Over 1.4 million properties in Switzerland are more than 40 years old. The current renovation rate is around 1% (= far too slow).

    The greatest lever for reducing CO2 emissions lies in the built environment.

    We are looking for a committed partner for a pilot project and later scaling of the Openly building system for renovations.

    Our spin-off, Valley-Architects.com, which has extensive experience and in-depth expertise in refurbishment and renovation, will take care of the architectural and approval aspects.

  • Which materials and construction variants have which CO2 footprint and which operating energy?

    How can existing development or renovation projects be optimized taking into account biogenic building materials and PlusEnergy?

    What additional monetization and financing opportunities arise in this context?

    We see ourselves as a complement ("extended arm") to established consulting firms such as Studio Durable, Lemon Consult and Drees & Sommer

    Excerpt from a current consulting mandate for OOS Architects.

Our guiding principle: Avoid CO2 emissions.

CO2 neutral construction

Thanks to the use of low-CO2 building materials, some of which also store CO2, Openly engineered houses are already low in CO2 during construction.

The Danish market has set itself the target of 6kg CO2 / m2 for 2029. Openly is already achieving this today.

Zero emission operation

OPENLY's achieve KfW 40 or PlusEnergy and Minergie P.
This is achieved by the good insulation values, the high storage mass, reduced window areas, the use of photovoltaics and an intelligent energy management system (OPEN SYSTEM©)

Durability
with value retention

For a planned service life of 100 years, based on a consistent cradle-to-cradle (C2C) approach.

This is why openly constructed buildings are valuable raw material depots.

Openly components are plugged or screwed, offering remarkable flexibility for future customization.
