Energy conservation measures are often combined into larger guaranteed Energy Savings Performance Contracts to maximize energy savings while minimizing disruption to building occupants by coordinating renovations. Some ECMs cost less to implement yet return higher energy savings. Traditionally, lighting projects were a good example of "low hanging fruit" that could be used to drive implementation of more substantial upgrades to HVAC systems in large facilities. Smaller buildings might combine window replacement with modern insulation using advanced building foams to improve energy for performance. Energy dashboard projects are a new kind of ECM that relies on the behavioral change of building occupants to save energy. When implemented as part of a program, case studies, such as that for the DC Schools, report energy savings up 30%. Under the right circumstances, open energy dashboards can even be implemented for free to improve upon these savings even more.
