Thermal renovation and installation of air recuperation in Special primary school Turkmenska
Vsetín, Zlín Region, Czech Republic
With the support from the Energy Agency of the Zlín Region the municipality submitted the application for funding to the national Operational Programme Environment 2014-2020. The application succeeded and the project was approved for funding. The final share of the subsidy was 23,6 % from the overall investment costs.
The outer walls were improved by 16 cm of EPS with l= 0,035 W/(mK) (U-value were reduced to 0,189-0,217 W/(m²K) depending on the initial construction). The roof were insulated with 280 mm mineral wool with l= 0,037 W/(mK). The existing windows with an average U-value of 2,7 W/(m²K) were replaced by new plastic windows with a U-value of 0,9 W/(m²K). The doors were improved with U = 1,2 W/(m²K)).
Because of the inadequate indoor environment air recuperation the air recuperation for whole school was projected with the overall power of 7 100 m3/h.
Nowadays, the heating demand of the building is 87 kWh/(m2.a), which means C-class for this type of building. The building wasn´t reconstructed to the A-class because of the inadequate cost for the material and the benefit is too speculative.
Energy management has been implemented on this building for ten year and EM is carried out by the Energy Agency of the Zlín Region.
Benefits
Overall reconstruction of the school has positive effect on the energy consumption and long-term sustainability of the whole project.
Project has generally improved visual appearance of the whole building.
Mechanical air-ventilation is necessary for the suitable indoor clime. Visible Benefit is the comfortable place for the teachers and students.
