To enable more energy retrofits for deeper savings, owners/managers and retrofit practitioners need to fully understand their value through case studies—or "true stories." Below is a summary table of recent deep energy retrofits. Select the the project or building of interest to you to see details, photos and downloadable PDF case studies.
It is important to note that the reported capital costs for most of these projects are gross project cost, not the incremental cost for efficiency.
Unfortunately it is very difficult to accurately account for the cost of efficiency. To date, only one project has done a good job of documenting these costs—and that is Empire State Building.
