Investment Costs of the Building Envelope Reconstructions

The article is aimed at the design of the measurements improving the thermal-technical properties of the building envelope from the point of view of the economic evaluation. The starting point for the evaluation of economic aspects is the quantification of the partial and total costs according to the individual constructions of the building envelope in relation to the earlier requirements. The result is the determination of the minimal thickness of the thermal insulation i.e. the determination of the corresponding properties of the building envelope. Described procedure represents the first step for the consecutive modelling of the potential investment options while comply with the optimal level according to Directive 2010/31/ES (EPBD II).
