The Revit model can be utilized in conjunction with Autodesk EcoTect analyis to conduct detailed Energy analysis. creating models suitable for day lighting analysis, solar shading studies, computational fluid dynamics (CFD) modeling, energy analysis etc. It is often required to use different models and different tools for different types of analysis, at different points of time in the process. In early-stages, conceptual energy modeling helps you to answer big questions about the building’s form. Later-on, detailed energy models can help to answer questions about the systems that meet the building’s energy demands (HVAC, lighting). Revit simplifies the process of Energy analysis from the conceptual stage making the attempt to attain Green Points easier.
In energy modeling, the results are based on:
The building geometry (i.e. shape, layout, wall constructions)
The thermal performance of that geometry (i.e. thermal and visual properties of wall and windows)
The building services used to meet energy demand (i.e. HVAC and lighting systems)
The occupancy of the building (i.e. building zones and operation schedules)
The properties of the climate (i.e. location, sunlight and cloud cover data)
The energy sources available at the building’s location (i.e. energy mix, energy costs)
This information can be accurately conveyed to the simulation software using BIM.
An example is the CFD analysis of the stadium roof for Outdoor Cooling in Al Arabi Stadium
