Frequently asked questions
What is renovativ?
It is a machine learning model that calculates the physical equations around the building model. It creates optimal building energy retrofit plans in minutes, rather than months. Our artificial intelligence uses more than 50 building parameters to deliver personalized renovation recommendations. You get a baseline model and 2–5 optimal retrofit packages with cost, savings, payback, EPC impact, and CO2 reduction for each building at the city scale. We serve municipalities, engineering consultancies, and building owners across Europe.
How is renovativ different from traditional thermal engineering?
Traditional thermal engineering can take months and cost thousands of euros for a single building assessment. Renovativ AI works 5,000 times faster, generating thousands of renovation scenarios in minutes. We've cloned physics-based simulations into machine learning models, making professional-grade retrofit planning accessible and scalable at city-wide levels.
Who is it for?
Municipalities, large portfolio owners, housing providers, and engineering firms that are planning renovations at the portfolio scale.
