4. Elementary school in Buštěhrad – case study
Design of four new classrooms including supporting facilities form teachers and extension of a capacity of dining-hall and kitchen;
Creation of a multipurpose space for meetings with parents and friends of school, presentations, school displays etc.;
Emphasis is put on increasing the quality of internal environment – external shading in summer time, system of mechanical ventilation etc.;
Effective energy and sources management and utilization of renewable energy resources that might have strong educational potential.

ENERGY CONCEPT (PV)
Total yearly electric energy consumption model (profile used for design of energy system). Energy consumption during summer holiday is minimal which means for example that produced energy from PV system in these months is hard to be consumed.
Installed output of PV system [kWp]
Yearly production of energy of PV system
[kWh]
Yearly usage of energy from PV system in the building
Coverage of yearly consumption
[%]
Yearly delivered energy into the distribution network (not used for own consumption)
Yearly take-off from the distribution network [kWh]

19. CONLUSION
School refurbishments overreach with their social aspect the scope of building engineering and architecture
Investigation of users‘ needs is essential
Participation and involvement of all stakeholders are important for successful completion
Subsidy system setup can negatively influence the whole refurbishment process
SBToolCZ serves as a quality assessment tool for school buildings and a guidline for thier renovations
