Energy Efficiency and Individual Housing

energy efficiency

Why is it important to improve the energy efficiency of existing buildings?

Residential buildings built before the second half of the twentieth century are clearly differentiated by geographical, climatic and regional conditions. Also, there is a difference between urban and rural areas.

After the second half of the twentieth century, we noticed that local elements in individual housing were weakening. The application of materials according to geographical conditions is no longer current, and uniformity in architectural expression is a basic feature. In most residential buildings, the materialization of the construction of masonry walls is dominated by brick or brick blocks. While in most of these buildings constructed before 1980, the thermal insulation of the facade was not represented. Also, many houses do not have a finished facade or any insulation in the later period

Since the implementation of the rulebook on energy efficiency of buildings, the use of thermal insulation has been noticeable, mainly in the minimum thickness of 5 cm, which still does not meet the requirements for quality insulation of the building. As the greatest energy losses occur through the openings of the building (windows and doors), their adequate replacement with more energy efficient elements greatly affects the better efficiency of the building.

In order to achieve adequate replacement and application of materials, it is necessary to determine the energy class of the facility when designing an energy efficiency study of the facility and, after the proposed measures, to influence the improvement of the energy class by at least one energy class.

What improvements to the facility can we influence and make the facility more efficient:

Exterior wall insulation

Choosing adequate windows

Roof insulation

Insulation of floors, ceilings

Possibility of using solar energy

Possibility of applying a more efficient heating system

Implementation of new lighting systems

Possibility of using heat pumps

There are many factors that influence the result of successful energy remediation of a building, starting with the current existing condition of the building, its geographical location, proposed remediation measures, and quality implementation of the foreseen measures.

Certainly, successful implementation requires analysis of the existing state, preparation of energy efficiency studies of the existing facility, as well as re-calculation, with adopted energy remediation measures that will influence the improvement of the energy class of the facility.
