In 2002, the second edition of the International Performance Measurement & Verification Protocol (IPMVP) said that whole building energy modeling, also known as Option C, should only be used for energy efficiency projects expecting to save greater than 10% of baseline consumption. However, the only data available for whole building modeling in 2002 was monthly billing data. Since 2007 AMI data has been revolutionizing the energy efficiency industry. IPMVP has kept pace with AMI deployment with...

With all energy efficiency program designs, the company makes changes to consumption and then calculates savings. Deemed savings estimates allow for engineers to make comparisons between equipment that was previously installed and estimate lifetime savings for new equipment. Whole building modeling gives programs the opportunity to do non-intrusive monitoring to look at the facility from a holistic view. One of the major benefits of using whole building approaches with utility data is the ability to monitor...

For many commercial customers, a slight shift in operational activity can result in a substantial reduction in energy costs each month. Electric demand is the rate at which a facility is using electricity at any given point in time, and utility companies will often charge customers based on the highest demand during any 15-minute period in a billing month. Any unpredictable spike in electricity usage can drastically impact your peak demand charge, and it is important...
