Energy Modeling (BEM) sub-program is an important part of BTO and its Emerging Technologies Program. BEM is a versatile, multipurpose tool that is used in new building and retrofit design, code compliance, green certification, qualification for tax credits and utility incentives, and even real-time building control.

Energy-modeling is the virtual or computerized simulation of a building or complex that focuses on energy consumption, utility bills and life cycle costs of various energy related items such as air conditioning, lights and hot water. It is also used to evaluate the payback of green energy solutions like solar panels and photovoltaics, wind turbines and high efficiency appliances. 

Energy-Analysis or Energy-modeling is used to:

• Predict the monthly energy consumption and bills
• Predict the annual energy cost
• Annual CO2 emmissions
• Compare and contrast different efficiency options
• Determine life cycle payback on various options
