Smart energy solutions for lower costs

We help you lower energy costs, from ventilation inspections to duct sealing and geothermal energy. Up to 70% savings.

We are your complete partner for heating, cooling and ventilation

When heating, cooling and ventilation are not working as they should, it shows fast, both in the indoor climate and on the bill. Warm radiators but cold apartments. Smoky air in the stairwell. Energy bills that keep rising without anyone really knowing why.

We help you reduce energy consumption, lower costs and create sustainable solutions with modern technology and proven methods. Since OVK ventilation inspections are a legal requirement for many properties, we often start there, often combined with an energy declaration that shows where the problems actually are. Based on the results, we propose the right measures, from small adjustments to larger installations.

We handle everything from OVK inspections, energy declarations and duct sealing to control and monitoring systems, ventilation, cooling systems, Smart VVC, solar energy and geothermal heating. With duct sealing, we renew the ventilation without tearing out a single duct, which can cut heating costs by up to 70 percent. Within geothermal energy, we combine district heating with borehole heating and have delivered solutions for over 250 housing associations and property companies, with savings of up to 50 percent.

The result is a property with lower operating costs, a more even indoor climate and a partner you can rely on throughout the process, from the first analysis to the finished solution.
