Assessment and Remodelling of a Conventional Building into a Green Building Using BIM

Abstract

The demand for sustainable buildings has been highly increasing over the past few years. To meet the sustainability requirements of a building, changes or decisions must be made to a building during the design and preconstruction stages. This can be possible using Building Information Modelling (BIM). To demonstrate the use of BIM in sustainable design, a villa is taken for model study. The conventional building performance is analysed using Autodesk Revit which included various parameters like energy use intensity, lifecycle energy use/cost, annual carbon emissions, monthly heating and cooling loads, monthly peak demand and monthly electricity and fuel consumption. By employing the use of green materials in the conventional building model, the conventional building model is modified into a green building model. Using BIM, the use of artificial resources can be greatly reduced by replacing them with the use of renewable energy resources thereby saving energy. To show how efficient BIM is, the results of the performance of the conventional and green building models are compared. BIM has proved to be efficient in achieving sustainability with earlier decision making and rectification of errors.
