Optimizing Envelope Design and Window Performance for Energy-Efficient Buildings Through Integration of Building Information and Energy Modeling (BIM-BEM)

Building energy efficiency is an important consideration for both new and existing buildings. Windows play a significant role in the energy efficiency of buildings, as it can be a major source of heat loss or gain. The window design can have a significant impact on a building's energy performance, as it affects the amount of solar radiation that enters the building and the amount of heat that is lost through the envelope. Therefore, it is an important consideration in building design, particularly for energy-efficient buildings. To reduce a building's Energy Use Intensity (EUI) and energy costs during its construction process, energy simulation and optimization models can be used in combination with window design (window-to-wall ratio, glazing properties) through a Building Information Modeling (BIM) and Building Energy Modeling (BEM). Using Autodesk Insight 360 with BEM is a powerful tool that can aid in the optimization of building designs and the reduction of energy consumption. The integration of these techniques can assist architects and building managers in evaluating the window design to improve the energy efficiency of buildings.
