Abstract: In order to lower the emissions of green-house gases it is necessary to explore the wide range
of the energy efficiency options. This thesis attempts to analyse the effect of thermal
insulation installed in the multi-family apartment buildings during the period of 2006-2012 in
the Czech Republic. We also investigate whether providing governmental funding further
improves energy performance of the insulated apartment buildings. In addition, we examine
the collective decision-making processes of members of the multi-family apartment building
associations, including their attitudes towards thermal insulation of their houses. The basis of
this thesis is the econometric panel data model (with 45 apartment buildings and their energy
consumption before and after the insulation) evaluated by the fixed effects method with
cluster confirming that the insulation, investments and public funding had all significant and
negative impact on the energy consumption in the buildings, when energy consumption was
adjusted for weather conditions. After the analysis it was concluded that the more the owners
invest in thermal insulation, the more they will save in the long run. The governmental
funding led to even greater energy savings and the grants that offer better interest rates on
loans are more efficient than the others. Our evidence also supports the notion that the energy
savings are lower in those apartment buildings that were insulated at a later stage, as opposed
to the apartment buildings that were insulated earlier. The more time passed after the
insulation, the less the owners typically saved for heating and that may point at rebound
effect
