Envelope Life Cycle Costing of Energy-Efficient Buildings in Ukraine

Abstract

The article describes main points and characteristics of the building envelope design considering life-cycle cost and compliance with the codes for energy efficiency parameters in Ukraine. This article contains of the problem analysis of the requirements development for the energy-efficient buildings parameters in Ukraine considering life-cycle cost in the walling design. The structural concepts for the thermal insulation of building exterior walls and roof coatings and their impact on energy efficiency are considered. Designing rational structural concepts for thermal insulating envelope of energy-efficient buildings. The role of the life cycle cost criterion in making decisions on the choice of building envelope is clarified. Analysis of activities, publications and regulatory documents in Ukraine and the EU-countries for the design of rational thermal insulating building envelope considering life-cycle cost to reducing energy consumption. The requirements of regulatory documents on the design of energy-efficient buildings in Ukraine are systematized. The variants of construction solutions for building envelope are considered in terms of the life-cycle cost and energy saving requirements. The tasks of choosing optimal solutions for enclosing structures of external walls and building coatings are multicriteria of a cardinal choice of alternatives with different important measures from a finite set of feasible solutions when considering a weakly structured problem with clearly defined separated parameters. Thermal insulating building envelope using modern insulation systems should be used in all types of buildings.
