Wege zur Plusenergieschule

Ways of realizing energy-plus schools.

As pilot projects energy-plus schools could play a key role in the exit from nuclear and fossil-fuel energy. Therefore the practicability of energy-plus schools was examined and a definition as well as a calculation methodology developed. In addition the calculation methodology was vetted regarding three schools using sensitivity analyses in which final and primary energy were evaluated.
Calculations show that all three schools could meet the energy-plus standard provided that they have very good insulation and efficient building technologies paired with a photovoltaic system. Heat must be generated primarily via sources of renewable energy. Whether a roof-top photovoltaic system is sufficient to generate the required energy depends on the massings of the school and the ratio between rooftop capacity for PV modules and energy requirements. If necessary multi-level buildings must be optimized by installing PV units in façades. Other methods of producing electricity (e.g. wind energy on school ground) cannot provide a significant contribution.
