About us

We are a team of energy specialists, engineers, designers and consultants who combine strong expertise with a practical, hands-on approach. We help cities, municipalities, companies and private investors design efficient, sustainable solutions — often supported by grants — from energy audits and Energy Performance Certificates (PENB) to expert assessments, Sustainable Energy and Climate Action Plans (SECAP), local energy strategies and funding advisory.

About us

With more than ten years of experience in design, energy performance and savings, we deliver solutions that are technically precise and easy to understand — with real impact. We improve comfort, reduce costs and help protect the environment. Clients across the Czech Republic place their trust in us repeatedly, return for new projects, and recommend us to others.

We work nationwide and are ready to be the partner you can rely on — from the first calculation to the final documentation needed to draw down your grant.
