We get lots of inquiries about solar cells on roofs – a very popular topic. At CEJ, we are passionate about solutions where sustainability goes hand in hand with sound economics and great aesthetics. Bricks with built-in solar cells is a good example of such a solution.

Healthy indoor climate

At CEJ, we see a direct connection between the health of a property and its residents. And you can actually get too much insulation.

As we improve our skill for insulating, sealing and optimising climate screens, new needs for sufficient airing and ventilation arise. CO2, moisture, mould, radon and draft highly affect resident comfort and well-being.

Green partnerships

Non-profit member organization set up to disseminate sustainability in construction. Mainly through certification of both buildings and urban areas and education of consultants based on the DGNB standard.

Energispring is a partnership between large building owners, managers, and interest groups in Copenhagen. The members work together to reduce energy consumption in the municipality’s buildings.
