Abstract


Building energy performance evaluation depends on several energy performance indicators. Estimating the total primary energy, the balance of renewable and non-renewable primary energy, the CO2 emissions or the energy labeling are now a requirement to several buildings. A detail insight into the total energy delivered to buildings, the partial energy supplied for heating, cooling, ventilation, humidity treatment, hot water and artificial lighting as well as the evaluation of thermal insulation of building envelope, its average heat transfer coefficient and the specification of the efficiency of the building service technical systems are ways to assess and improve its performance. Overall the optimization of energy renovation of buildings is based on cost/performance analysis of building energy efficiency and sustainability.

This paper presents a study of the energy evaluation of several school buildings in Central Europe region. The buildings are representative of different types of school buildings constructed during the 20th century. The studied buildings are considered energy inefficient. Possibilities for buildings’ renovation promoting energy savings and indoor climate comfort are summarized. Main strategies focused on improving the building envelope, their thermal properties and window retrofit.
