MULTI PARAMETER ANALYSIS FOR CALCULATING MINIMUM EUI OF A BUILDING USING GREEN BUILDING STUDIO AND REVIT

Abstract

A zero energy building (ZEB) or net zero energy building is a general term applied to a building with zero net energy consumption and zero carbon emissions, calculated over a period of time.The most important parameter in the analysis of a zero energy building is EUI. EUI stands for Energy Use Intensity;the EUI expresses a building’s energy use as a function of its size or other characteristics.The EUI is expressed as energy per square metre per year. It’s calculated by dividing the total energy consumed by the building in one year (MJ) by the total gross floor area of the building. In the analysis of a zero energy building our main motive is to minimize the EUI using different parameters.

So, the concept of Zero Energy Building has been analysed for different shape of buildings. Three different shapes were taken 120 shape, hollow cylinder shape, plus shape and out of these three shapes it was found out that hollow cylinder shape has minimum EUI, after that detailed analysis of G+10 Hollow cylindrical shape building considering material and glazing has been done. Seven cases has been analysed by changing the material and glazing. The minimum EUI case will be the best for the building to be considered as a zero energy building.The analysis is done in Autodesk Revit (2017) using Green Building Studio.
