ABSTRACT
ABSTRACT: The content of paper is energy analysis where the impact of accumulated effect of building construction on operative temperature trends in analysed room is evaluated. In this case study of classroom with sloping roof and roof windows was selecting. There are compared two types of building constructions, so called lightweight and heavyweight construction. There is taken account with natural and mechanical ventilation in analysed room for booth construction types. The results from energy simulation show positive impact of heavyweight construction on max operative temperature in room for booth ventilation regimes. The results are output from dynamic energy simulation was elaborated by tool DesignBuilder. This simulation programme uses calculating tool EnergyPlus.
