Abstract
Prefabricated housing estates represent an important urban, architectural and historical phenomenon in the Czech Republic. Most people prefer to live in prefabricated buildings because of their central location, good transport services and a lot of amenities in their vicinity. Owners or tenants of flats prefer prefabricated buildings after revitalization, as they are more affordable than new developments and at the same time do not have such high energy consumption costs as prefabricated buildings without revitalization. The paper aims to focus on the energy savings of a specific prefabricated building. The heating consumption and the resulting monetary savings are addressed. The aim of the research is the performance of economic and life cycle analyses of the building. Firstly, the original condition of the prefabricated building and the extent of the revitalization carried out in 2001 were specified. Secondly, an energy assessment of the apartment building was carried out, where the heating consumption before and after the revitalization of the apartment building was determined and the resulting heat savings for each year of the assessment were determined in the appropriate units (GJ, kWh/(m2/yr)). Economic indicators and life cycle costs were determined based on the modelling of the heat price development and possible energy savings. Currently, there has been a huge increase in energy prices. The reason for the price increase is the current situation in the wholesale market, where the prices have been reaching extreme amounts for several months and their further development is difficult to predict. The energy crisis has deepened as a result of the geopolitical situation. Customers are expected to experience a further increase in the electricity and gas prices since the prices can increase by up to tens of per cent.
