In the undergraduate thesis, the production of the calculated energy performance certificate
for the specific building is undertaken. This is done with the emphasis on recommendations
for energy renovation of the duplex residential building, which is located in Medvode,
Slovenia and was built in 1985. When the building was constructed, energy efficiency was
already gaining importance. Consequently many buildings constructed in this period were
moderately thermally insulated. An energy performance certificate is legally required when a
building is offered for purchase and when it is leased for a period longer than one year.
Furthermore the certificate is mandatory for newly built properties, as a basic requirement for
the project plan. The thesis initially examines the current legislation, which regulates the area
of energy efficiency in buildings. Next the energy performance for the considered building will
be produced. This will be done with TEDI and TOST computer software. After that, individual
technical measures will be analysed. The viability of these measures will be assessed in
consideration of technical complexity and estimated energy savings potential. For the
considered building, the greatest energy savings can be realised with exterior joinery
renovation and installation of heat recovery ventilation. The implementation of booth
measures accounts for about 50% of energy savings. With the comprehensive renovation,
more than 80% of the annual heat required for the building would be preserved. In this case
the specific heat transfer coefficient would decrease by about 60 %. On the contrary the
requirements for cooling would increase, which is the common downside of a well-insulated
building.
