Alternative perimeter cladding compositions for nearly zero-energy buildings.

A building with zero energy consumption is characterized by significantly lower energy consumption than the corresponding mandatory requirements of building energy regulations at the beginning of the 21st century. Energy-efficient buildings place high demands on the quality of thermal insulation. It is important to characterize the parameters of the building envelope, i.e., envelope construction of the perimeter cladding, roof cladding, floor on the ground or ceiling above the unheated basement, and infill structure (windows, doors), which acts as a thermal envelope of the building. The aim of this paper is to design and compare eight perimeter cladding compositions and evaluate alternative perimeter cladding compositions using the methods used to evaluate the complex quality of buildings. Main criteria define the area of possible solutions and exclude solutions that, for example, are in conflict with legislative requirements. Optimization criteria are used as the basis for the multicriteria evaluation of complex quality. The traditional approach to building assessment requires a reduction in the number of criteria and a focus on the current essential design criteria. Perimeter claddings are designed as multilayer structures insulated with two methods of insulation with different materials based on the infill structure and thermal insulation. [ABSTRACT FROM AUTHOR]
