Real-Time Energy Management: A Case study of Three Large Commercial Buildings in Washington, D.C.

This case study found that Tower’s real-time energy management initiative achieved a 13.2 percent reduction in electricity use in the three buildings, showing that substantial gains are possible when building owners operate their buildings with attention devoted to reducing the amount of energy wasted.

The energy management initiative that produced these strong results focused on operational improvements—measures that do not require construction, disruption to an occupied office building, or substantial capital investment. This case study provides building owners, tenants, efficiency programs, and others with a model of an energy management initiative with proven results.
