INTRODUCTION
Existing inefficient building stock contributes high volume of energy consumption, and 85% of the predicted building stock in the year 2050 is already built [36]. Many governments and relevant communities make a lot of effort on the decarbonising in the construction industry, and BIM is at the center of controversy. BIM based technology to enhance the energy performance have improved in short period intensively over the last decade [39][43], mainly been used in the early stage of design and construction phase [3]. Efficient ways for contributing retrofit and refurbishment project still lies behind in practical implementation [39], where has great potential for the buildings to be extension their life or to return to 2nd Gradle …show more content…
