Energy modeling, or simulation, is a method for predicting building energy consumption in order to understand a building’s energy performance, guide informed design practices, and generate savings opportunities. When utilized early in the iterative design process, an energy model can be used by designers and engineers to help make decisions to maximize system efficiency while not compromising performance. The model is based on the building’s thermal characteristics including the building envelope, wall materials, size and orientation of the building, building occupancy, and operations and maintenance practices. The models are always normalized by weather in the local climate.
Healthy Buildings’ engineers utilize a wide range of energy modeling software, including eQuest, Energy PRO, Trane Trace, and more, depending on which is most suitable for the project. Energy modeling software allows our engineers to utilize local weather data and reasonable utility consumption information to build complex building system models in the design process. Furthermore, energy modeling may be utilized during the energy audit process to develop a base case scenario and compare with the predicted consumption levels associated with energy conservation measures identified by the engineering team. In this manner, the modeling is integral to determining the cost-effectiveness of each measure.
