Energy Audit of a Community Center

Abstract

The aim of the study is to conduct an energy audit of the cultural center and museum at a community center in town of Mizia, Bulgaria. This audit includes a detailed analysis of existing condition of the building, as well as the energy systems used - heating, lighting and cooling. Energy-saving measures have been proposed such as installing thermal insulation on buildings’ enclosing structures, replacing windows and doors in the building, installing high-efficiency VRF air conditioning systems, replacing old lighting fixtures with high-efficiency ones, installing a PV system for generating electricity. The total energy savings from the measures amount to 89273 kWh/year of electrical energy, with the environmental equivalent of the energy savings amounting to 51.64 t CО2/year. After the audit, the building falls into class "B" on energy consumption scale. After implementing the prescribed energy savings measures, it can be summarized that it will meet energy consumption class "A" on the energy consumption scale.
