An Assessment of Potential Energy Savings for
a Model Building in Relation to its Age and
Construction Technique
The project analyses heat losses through the external envelope of a building in
relation to both its age and the application of heat and energy efficiency regulation
requirements during its construction. This information is used to assess potential
energy savings that can be achieved by increasing thermal insulation.
Today’s residential and public buildings with inadequate heat insulation dominate
new ones. By comprehensively increasing energy savings in buildings, one aims
to create adequate prerequisites for systematic improvements and reconstructions
of the existing building stock. Another goal is to increase the level of mandatory
heat insulation within new buildings. These processes are in conformity with
the EU Directive 2002/91 on the energy performance of buildings.
The study analyses construction techniques for buildings erected before 1970,
i.e. before thermal protection and energy savings were regulated in Croatia. Next,
it analyses construction techniques in the period between 1970 and 1987 and
after 1987 when existing regulation on thermal protection and energy savings in
buildings was enacted. Heat losses can be reduced up to 60 - 80 percent by
increasing the level of thermal protection of the external envelope.
