Energy modeling

Definition

Energy modeling is the process of creating a computational representation of a building's energy performance to evaluate and optimize energy use, efficiency, and sustainability. By simulating how a building interacts with its environment, energy modeling helps engineers and architects identify opportunities for energy savings, assess renewable energy options, and comply with building codes and standards.
