Energy rating system can be considered as a key policy instrument that will assist government to reduce energy consumption. Existing rating systems in the world only considered limited factors related to energy consumption, and to provide more accurate rating system, it is proposed that a more sustainable energy rating system should be developed co...

... Similar research proposes the concentrating on green BIM, and suggests that with the utilization of a decision-making process when executing BPA to get design proposals with enhanced environmental effectiveness based on climatic condition of the location (Ebrahim and Wayal 2019). Another study was conducted which analyzed energy efficiency of the building properties and the asset rating methodology was utilized, where modeling is performed and energy consumption for thermal comfort and lighting is estimated (Pathirana et al. 2020). ...
Large amount of energy is being consumed by the buildings at its operational phase and it is one of the significant source of carbon discharge throughout their service life, which directly affects global warming. Therefore, it is essential to optimize energy use intensity (EUI) as well as energy cost with the utilization of the building information modeling technology (BIM) to perform energy analysis. Objective of the study is to study modeling software for energy simulation and to evaluate different measures by altering design criteria’s and thereby reducing energy consumption for achieving best energy-efficient building in terms of EUI and energy cost. In this study, an attempt has been made to evaluate the EUI and energy cost of a commercial building located in Vadodara City, Gujarat, India. Modeling of the building is performed by utilizing Autodesk Revit Architecture, and further for energy analysis, Autodesk Insight is used. These study targets are to provide energy-efficient building by varying different design strategies with respect to EUI and energy cost based on ASHRAE 90.1 standards. It is observed that with the minor variation in design strategies causes large percentage of difference in the EUI as well as energy cost. Present work concludes from the energy analysis that energy cost can be reduced up to a great extent by implementing BIM which is helpful to implement better design options prior to construction of building by optimizing annual energy budget incurred compared to traditional methods which may involve errors in computations.
