Bim-Based Energy Analysis Of Conventional Residential Buildings In Hot-Humid Climate
As the campaign to raise international awareness towards saving the environment is growing, the need for
studies to assess the building performances in terms of energy efficiency for Malaysia as a developing country is perceived
more than ever. In line with the growing global trend toward energy efficiency in buildings, this paper makes attempt to
estimate and analyse the performance of conventional buildings in terms of the associated dominant load; cooling load for
the context of Malaysia through innovative workflow of Building Information Modelling (BIM). A double storey bungalow
located in Kuala Lumpur was modelled in Revit Architecture and exported to Autodesk Ecotect Analysis, which both of
them are the epitome of BIM tools, for energy analysis. The properties of the components including walls, roofs and
windows were input into Ecotect and the simulations were run by varying the orientation and monthly climatic data. Total
numbers of 48 simulations were conducted to calculate the monthly cooling load of the building for four orientations and 12
months. It was observed that throughout of the year, cooling loads are constantly required to maintain the comfort band
however north orientation seems somewhat energy efficient rather than the others. The present study took a step towards
more energy efficient buildings by providing succinct information regarding the performance of buildings in hot-humid
climate and aimed at examining BIM-based building energy simulation.
