Energy Models provide information on the current energy consumption and costs at a facility as well as a breakdown of consumption by end use. Energy Data Services utilizes the eQUEST building energy modeling software package. An eQUEST model takes into account the building geometry, orientation, construction materials, schedules, and conditioning systems as well as annual local weather data, in order to generate a viable estimate of the building's annual energy profile. Energy Data Services has completed Energy Models on a wide range of facility types, from multi-family properties to casino resorts and large industrial facilities. Energy Models are a useful tool for Energy Audits on existing buildings as well as an essential step in pursuit of Green Globes or LEED certifications for new construction.
