Abstract - The design of energy efficient buildings is becoming a need to reduce environment impact. Hence it has become necessary to design or plan the buildings in different forms with different parameters to make it energy efficient. This research report presents quantitative study of energy performance effect due to building morphology in five different climatic zones. Using four building parameters (i.e., relative compactness, orientation; window percentage; sun shading) an optimal building morphology has been suggested for specific Indian climatic zones i.e., Hot and Dry, Warm and Humid, Composite, Cold and Temperate.
The software to be used for energy Analysis for buildings is AUTODESKINSIGHT360 software.
Key Words: ENERGY EFFICIENT BUILDING, ORIENTATION, OVERHANG SHADE, CLIMATIC ZONES, BUILDING MORPHOLOGY, HEATING AND COOLING LOADS, REVIT, INSIGHT 360
Thebuildingsectormakesasignificantcontributiontototal energyconsumption.Thisisoneofthereasonswhyenergy efficiency measures in buildings are increasingly being demanded. Worldwide, the issue of energy efficiency has gained relevance in the last decade with the objective of reducing energy consumption that would impact the buildingperformanceaccordingtotheInternationalEnergy Agency(IEA).Thegrowthofnewtechnologiesbroughtmany changesinbuildingdesignandenergyanalysisprocess.Itis now more crucial than ever to choose from a variety of solutionstoincreasecomfort,cutcarbondioxideemissions, andmaximizebuildingprofitability.Theincreasingdemand for more energy efficient buildings led scientists in the worldtoengageinbuildingenergymodelingtoimplement the strategies that would affect an overall reduction in buildingenergyconsumption.Buildingenergymodelingisa process of creating an architectural and energy model throughcomputersoftwaretopredictenergyconsumption and improving building energy performance during occupancy.Comparingthepredictedenergyconsumptionto theactualenergyconsumptioncanhelpbuildingownersand

1. Relative Compactness (0.6)
A modular geometry system was derived based on an elementary cube(5x5x5m): To generate different building shapes, such elements were used. These elements were aggregated in different ways to create 70 morphological variationsamongwhichninewereselectedonthebasisof geometric index and relative compactness. The "relative compactness" (RC) indicator was employed to define compactness.TheRCofashapeisderivedinthatitsvolume tosurface ration iscomparedto thatof themostcompact shapewithsamevolume.
According to relative compactness of each building shape theyweredividedintoninegroups0.6,0.65,0.7,0.75,0.8, 0.85,0.9,0.95,1.Theshapesofbuildingswhichwerehaving commonrelativecompactnesswereclubbedintoonegroup among nine above. Then one shape from each group was selected and then analyzed through software (Autodesk Insight 360)Analysis.
Following are the examples of different building shapes grouped according to relative compactness among the 70 woodenmodels.
