A building energy model is a simulation based on building design, envelope, orientation, weather, schedules, controls, and energy-using systems to project comparative energy consumption and costs. Using building modeling, Entegrity can prioritize energy efficiency measures by first cost, rate of return, and environmental impact. Our team utilizes the most advanced modeling software, including IES Virtual Environment, Trane Trace, and Energy Plus.
Building modeling provides the most value early in the design process when design decisions such as orientation, floor plan, and HVAC systems have yet to be determined. Analysis can include:
- Energy Conservation Measures
- Net Zero Energy
- Sustainability Rating Systems
- Load Checks
- Access to Views
- Hygrothermal Movement
- Life-cycle Cost
- Utility Incentive Potential
- Code Compliance
- Measurement & Verification
The cost of building modeling is based on the amount of time necessary to produce the simulation results. Our team develops a range of scenarios, runs simulations to determine how these will perform, and prepares recommendations for improvement. More unique space types, ventilation/HVAC zones, number of desired iterations, and amount of desired feedback will affect time and cost.
The average payback for modeling is 1.6 years, with larger projects paying back faster. If we remove buildings less than 25k ft2, the average payback is less than six months.
