Summary
The project was focused on renewing an old building of nursery school, built in 1978. The aim was to build 4 new flats (for teacher's families) and to realise new, innovative and environmentally positive system of energy concept created by solar system, biomass boiler for wood chips and underground heat exchanger for heat recuperation. The part of energy concept for the building was solved in the frame of research project of the Ministry of Environment CR.
Results
The energy consumption for heating before reconstruction was 220 kWh/m2.year, after the reconstruction the consumption is 46 kWh/m2.year. The energy produced by renewables are 100 %, it means 75 % of solar contribution to hot water preparation (25,7 MWh/year) and 89 % contribution of biomass to heating (51,9 MWh/year). The economic benefits are 100 % independence of outside suppliers of fuels. The environmental benefits are that the application of renewable energy will save about 30 tons of CO2 per year.
Two jobs were created in the process of biomass chips production. The behavioural changes achieved were the strong educational impact to small children that it is possible to live in building heated by the sun.
