In the recent years, there is growing interest with building owners for reducing energy costs and GHG emissions. The first step for any significant energy efficiency initiative is an Energy Study to identify the right solutions for a specific facility.

There are four levels of energy studies outlined in the attached paper.
Building a business case for energy efficiency initiative does not have to be expensive.
