Assessment of the Energy - Efficient Modernization of Residential Historical Buildings in Kiev

Abstract

Abstract. Most of residential historical buildings in Kyiv, Ukraine are in need of energy efficiency modernization. The present research exposes the assessment of warming effectiveness for the certain enclosing structures in historical residential buildings, considering the overall thermal balance of building. Heat losses through certain enclosing structures considering actual thermal resistance were estimated, also in compliance with standard requirements for thermal resistance of enclosing structures according to the standard DBN В.2.6-31:2006. It turned out that the warming of the whole building envelope and the replacement of transparent enclosing structures allows to reduce the heat flux of the heating system for compensation of thermal losses through the building envelope in 3 times.

Energy efficiency of industrial facilities as a factor of sustainable development of the country's economy

“…Technical innovations lead to more efficient use of energy resources in the organization, but their streamlining makes the process of energy saving and energy efficiency more sustainable and predictable, and improve the functioning of the company as a whole [7][8][9][10]. The introduction of EMS allows the implementation of a systematic approach into energy management.…”

Architectural possibilities of using PVC window units in historical buildings

“…Due to the fact that they have a smaller thickness (8.5 mm) compared to standard insulating glass units (minimum 14-16 mm), they can be used instead of common glass in old window units after the milling of window glass holder. The following technical issues of design and operation also require detailed study [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]: -providing thermal protection of buildings when replacing window units in historical buildings during winter operation which was caused by a change in the thermal conditions of the junction of window units to the exterior walls.…”
