It’s not just about obtaining a return.
After reviewing the significant rate of return possible, the more prudent question is: Why have we not looked at and implemented this technology in the past?
Quantifying the rate of return is no longer a mystery; software and energy assessment procedures are proven and readily available.
It has been estimated that a building’s initial construction cost represents only 20 to 30 percent of the building’s entire cost over its 30- to 40- year life. So the life-cycle cost of the total project deserves consideration, rather than focusing solely on the initial capital cost.
