Building energy simulation uses a mathematical model, as a description of the behavior of a building and its systems, to estimate the energy usage and demand of a building. The simulation provides valuable information that empowers designers and owners to make informed decisions.

The two approaches for building energy simulation are the Data-Driven Model and the Forward Model. The Data-Driven Model approach is used for developing a baseline on an existing building with known data. The Forward Model approach is used as a prediction of a future building. The approach that is selected depends on the project’s starting point.

Building EnergetiCx has successfully provided several building energy simulations to comply with LEED®, municipal, and federal requirements. Our team will become an integral part of the design team and will prepare the building energy simulation model required to demonstrate the whole building energy savings. Building EnergetiCx can also provide the required supporting

report to compare the proposed building to the ASHRAE Standard 90.1 ”baseline building”.

The building energy simulation process should begin as early in the design as possible and be an iterative process which evaluates the interdependencies between the different building elements (e.g. lighting, envelope, and HVAC) throughout the design. The building energy simulation process consists of four main components: load analysis, system analysis, plant analysis, and economic analysis.
