What others are saying.

I am looking forward to convening a group of my retail sector peers in Building Energy to use the full range of its apps so that we may learn from each other’s data in a protected setting. The DOE adds a dimension of data so that we will be able to quickly and easily compare building performance across our own portfolios and the DOE portfolio to identify optimal measures for energy savings and GHG reduction.
