Impact of the Shading System Properties on the Overall Energy Performance of Office Buildings
Abstract
The cooling energy consumption in buildings is becoming a crucial point the national energy end uses. The trend is continuously growing, while is decreasing for other energy uses. Legislative bodies took note of this situation and included a number of cooling efficient solutions in latest standards. Shading devices are one of the mandatory solutions. Nevertheless shading devices affect not only the cooling energy uses but also the heating demand and the power consumption for artificial lighting. This paper present the results of a wide numerical analysis campaign performed with the objective of demonstrate the global energy benefits (heating, cooling and artificial lighting) in office buildings located in different Italian areas a function of: shading system properties, position respect to the glazing unit, glazing properties, control strategy.
