ECONOMIC ASSESSMENT OF INCREASING THERMAL PROTECTION OF MUNICIPAL BUILDINGS TO MODERN EUROPEAN REQUIREMENTS

Abstract

According to the plan to reduce carbon dioxide emissions in Ukraine, there is a need to replace traditional energy sources and, accordingly, types of fuel. The paper highlights the main differences between the current regulatory documents in the field of energy efficiency of buildings, analyzes the dynamics of the energy demand of a public building during its thermal modernization to the normative indicators in force in Ukraine and Europe, and the regulation of the heating and ventilation schedule. The energy consumption assessment is based on the results of calculations in accordance with the current standard DSTU A.2.2 - 12:2015 and the building model in the DesignBuilder software environment. Using DesignBuilder helps evaluate new and existing building environmental performance, energy and comfort, HVAC, daylighting, cost, design optimization, CFD, BREEAM/LEED credits and reports that meet multiple national building codes and certification standards.

The influence of the economic indicators of Ukraine and Europe on the overall sensitivity of the project to increase the thermal protection of a public building is studied, taking into account the historical increase in energy prices in the countries under consideration. The work is the basis for further analysis and development of the concept of buildings with almost zero energy consumption in Ukraine.
