The Minister of Economic Affairs and Communications Taavi Aas, and representatives of Timbeco, KredEx, Saue Rural Municipality, and Tallinn University of Technology attended the opening.

The factory reconstruction was quick and smooth, and disrupted the daily life of residents significantly less than regular external wall insulation work with scaffolding. Buildings are normally renovated in the same way they are constructed. In this case, with the support of the KredEx and Horizon 2020 project DRIVE0, the experts of Timbeco Ehitus first constructed the necessary modules in the factory. Ventilation pipes were integrated into the modular additional insulation elements and installed in the building together with the exterior walls.

These modules can be used to fully renovate many of the typical apartment buildings constructed in Estonia before the 1990s, many of which can also be found in other countries in Scandinavia and Central Europe. The first building that was renovated in such a fashion was the Akadeemia 5A family dormitory of TalTech, which the French housing minister was intrigued by and visited in the beginning of February.

The building located at Kuuma 4 is very special and serves as an example for the reconstruction of other apartment buildings. The apartment buildings constructed in Estonia before the 1990s all have quite similar problems: high energy consumption levels, poor ventilation and indoor climate, and uneven indoor temperatures. Many apartment associations have plans to renovate their buildings. The Kuuma 4 building shows that renovations can be done conveniently and efficiently.

The construction scientists of TalTech were advisors in the reconstruction of the apartment building in Saue.

The Akadeemia 5A family dormitory of TalTech was the first apartment building in Estonia that was renovated to a nearly zero-energy building, in 2018. The family dormitory of the Tallinn University of Technology served as a template for the reconstruction of the Kuuma 4 building.
