Businesses’ energy intensity – measured by kWh per square foot – declined by 8 percent from Q1 2009 to Q3 2011, according to customer data from energy management company Ecova.
Big box retailers, those with floor space of 25,000 square feet or more, saw their energy intensity fall by 10 percent over that time period, the largest percentage fall of any sector, according to Ecova’s white paper, A Big Data Look At Energy Trends: 2009-2011.
Fast food restaurants saw their energy intensity fall by 3.8 percent over that time period, the smallest percentage fall of any sector.
Leveraging data such as that in the white paper holds the key for large organizations wanting to prioritize energy efficiency improvements, the company says.
In January, Ecova announced that it was buying LPB Energy Management. The acquisition grew Ecova’s client base to nearly 700 commercial companies and gave it new offices in Dallas and Houston.
In December Rite Aid selected Ecova to provide utility expense and energy management services for its 4,700 U.S. locations.
