Energy Efficiency of Housing Buildings
Energy efficiency of housing buildings means the wise use of electrical and heating energy at home or working place. Energy efficiency directly concerns the decrease of losses in electrical and heating networks as well as the efficiency increase of equipment that produces energy. The impact from the implementation of energy efficiency measures results in diminishing the household expenses, increasing the quality of life and achieving better external view of buildings. There are different energy efficiency measures that depend on concrete needs and planned results for various buildings. The renovation of housing buildings is one of the main methods to achieve energy efficiency. Refurbishment is a renovation of buildings or parts of them that includes all necessary actions to put the energy characteristics of housing buildings in accordance with regulatory requirements as well as the expectations of residents. The best and guaranteed effect from the housing renovation and respectively the most economically profitable package of improving measures is achieved after preliminary detailed investigation of the building and energy expenses. This is the basis for analysis of each concrete case and implementation of several packages of energy efficiency measures with guaranteed results at different price levels. It is not compulsory to perform an overall renovation in order to improve the energy characteristics. The selection of technical measures depends on the preliminary energy audit and analysis of each concrete case. A special instruction for the effective use of the building or equipment is prepared together with the plan for renovation.
