The municipality submitted the application for funding to the national Operational Programme Environment 2014-2020, with the support from the Energy Agency of the Zlín Region. The application succeeded and the project was approved for funding. The final share of the subsidy from OP Environment was 30,4 % from the overall investment costs.
The facade was improved by 16 cm of EPS with λ= 0,039 W/(mK). The ceiling was insulated with 200 mm mineral wool with λ= 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 to U = 1,2 W/(m²K)).
The air recuperation for the whole school was projected with the overall power of 1 475 m3/h because of the inadequate indoor environment.
