These guidelines provide a proven strategy for major energy efficiency retrofits, which includes benchmarking with ENERGY STAR Portfolio Manager.
The guidelines will help you to:
■ Assess the opportunity for energy improvement in your building and determine which energy efficiency measures are most appropriate.
■ Develop a plan, incorporating appropriate timing with a compelling business case.
■ Understand how to implement major energy retrofits.
■ Maintain the post-retrofit performance to maximize the return on investment.
Since major retrofit projects are often driven by a desire to improve energy efficiency as well as regular asset renewal, they are best implemented using a systematic approach – to eliminate waste, improve efficiency and right-size equipment.
Major energy efficiency retrofits involve several energy retrofit measures across more than one building system. They typically lead to energy savings of 15 to 40%.
