The article discusses the influence of big glazing facades on the needs for heating and cooling energy.
Three ways of modelling the needs for energy were chosen. The influence of the orientation of the glazing facade and different heat – optical features of glazing on energy needs was established. The paper analyzed the influence of the measures of passive energy saving on the needs for heating and cooling.
A comparison of calculation results applying two methods suggesting the needs for cooling energy was made and energy costs of actual and normal heating were examined.
