Energy Modeling

What Is It?

Energy modeling predicts the energy cost and performance of a building compared to code requirements, based on data input into a computer program for simulation. Inputs into the program include site location; R- and U- values of the walls; roofs and window assemblies; occupancy schedule; mechanical equipment; lighting power density; and process load percentages. Energy modeling should be used to inform design decisions and as an integrated design tool. Each decision should contribute to the optimization of the design in the context of project parameters and all other decisions. The goal of the energy model is to demonstrate performance of the design with the intention of reducing demand, harvesting available free energy, increasing efficiency, and recovering waste energy.
