Study Results and Obtaining High Ventilation Air Quality in Architecture for an Old Shopping Centre Public Utility Building with Modernised EL. Heating in Warsaw, District, Poland

The subject of this paper is the study of a public utility building, a shopping centre in Warsaw/Targówek, carried out as part of the programme of “Research for obtaining high air quality in architecture. The purpose of the study of the building is to utilise a new technology which will lead to reductions in electrical and heat energy consumption and cuts in CO₂ emissions in the modernised Shopping Centre Public Utility Building in Warsaw. The building is equipped with systems for obtaining heat and cold from groundwater and is adapted to a low electrical energy consumption level with the lowest primary energy ratio in Poland. It is located in Warsaw and, in addition to the energy sourcing system, features a highly modern control system (BMS). The objective of the study is to demonstrate operating costs for a building with low exterior wall and roof insulation parameters. In addition, the building uses a heating system based solely on electrical heating due to its lack of access to gas and district heating. The conducted studies and analyses allowed a comparison of the operating costs of old buildings following modernisation with those of new buildings.
