About Termavia
The data a mandatory building document needs is already public, yet specialists still copy it by hand. We build the platform that does that part, and then checks whether renovation delivers what was promised
Out of every 100
Spain
residential buildings were put up before 1980, around 5.5 million of 9.8 million
Housing stock data from the 2021 census and Law 10/2022
Why we started
When a building needs an energy certificate, a building book or an evaluation report, an accredited specialist spends between 3 and 22 hours on it, and around seven tenths of that time goes on finding and re-keying data the state has already published
Geometry, year of construction, floor areas, orientation, previous certificates and climate series sit with five agencies in five formats. We connect them, so the technician starts from a complete record and spends the visit on what actually needs professional judgement
Then we go one step further than the industry does today. We calibrate the model of each building against its real consumption, measure the result after the works and publish how close our forecasts came. Every building processed makes the next one of the same type easier to document
What the state already publishes should not be typed in by hand again
We work within accreditation. The technician visits, judges, signs and stays responsible
Forecasts come with an interval, and we publish how accurate they turn out to be

Where we are going
Each certificate register is connected one community at a time. The order follows the maturity of the rules, the reuse of what is already built and the size of the market
Step 1 of 6
The home market, with the most mature regime of mandatory documentation in Spain and the densest target stock. The first register to be connected
Why it matters for Spain
At these volumes the bottleneck is the speed at which the technical justification for each property can be prepared. Without an existing building book or an evaluation report, access to a support programme stays closed
primary energy use of the housing stock by 2030 and by 2035, against 2020
National Renovation Plandwellings, the comprehensive renovation equivalent needed by 2030
National Renovation Plandwellings a year to be renovated with public support
State Housing Plan 2026–2030for renovation within the State Housing Plan
Royal Decree 326/2026Building books and evaluation reports ready sooner, so owners can apply for support
A database linking building typology, the works carried out and the measured result, with anonymised indicators shared with public authorities
The profession now opens to vocational qualifications. The platform takes the data work, so new specialists focus on judgement on site
