Building energy modeling provides a visual representation of building energy consumption to identify where, when, and how much energy is being used. Energy usage is broken down and quantified, allowing for extensive analysis of conservation opportunities. Energy efficiency measures can be modeled individually or comprehensively, allowing for customized projections of energy savings. Any proposed retrofits or controls modifications are analyzed to weigh the costs and benefits of such modifications.
The engineers at ERI have extensive experience with whole-building energy modeling for both retrofit and new construction projects. ERI staff work daily with building codes and bring this knowledge of design procedures to the design team. ERI has modeled a wide range of energy consuming systems including building envelope, HVAC, controls, lighting, motors, variable speed drives, transformers, insulation, windows and other building systems. All energy models are calibrated within 3% of the historical energy use for the building to ensure accuracy in the model. In addition, ERI ensures that all energy models are subject to an internal peer quality control review to allow for a consistent and thorough approach. After a baseline is established, the model is used to investigate various energy efficiency measures (lighting upgrades, HVAC retrofits, controls, building envelope, etc.) and cost effectiveness of projects is thoroughly evaluated.
Building owners and designers benefit from energy modeling by understanding the options available for optimizing building design to achieve energy savings and carbon reduction. The information provided by accurate energy modeling assists decision makers with a strategic energy reduction approach to pursue investments that have the greatest impact.
