Standard energy retrofitting of buildings in Slovakia has over the last decades led to an increase of thermal insulation of
the building envelope. In order to provide more benefits to building users, considering also other, non-energetic aspects,
an increased interest can be seen on the improvement of indoor acoustic comfort.
Our everyday experience shows, that when it comes to the assessment of the quality of building façades, many
shortcoming can be seen in the design, realisation and even in legislation. Decisions on criteria and requirements in
building acoustics and thus also on requirements on the building envelope, are based on the recommendation of World
Health Organisation that uses large scale studies on noise effects on health. Standards typically suggest minimum sound
insulation properties of the building elements for exposure to exterior noise.
The most typical examples of the standard energy retrofitting of buildings in Slovakia, involve dwelling houses (usually
massive façades with External Thermal Insulation Composite System ETICS), administrative buildings (light-weight
façades – single leaf or double leaf) and industrial buildings (insulation of noise generated inside buildings).
This contribution is listing the weak points and crucial parts of façades’ design, typical for Slovak architecture.
