AMERESCO CUSTOMERS MINNESOTA STATE UNIVERSITY, MANKATO AND THE CITY OF MANKATO WIN ENVIRONMENTAL INITIATIVE AWARDS

The university is awarded with the Sustainable Leadership (Large Employer) Award and the City is recognized in the Energy Climate and Change Category

FRAMINGHAM, MASS.– August 5, 2019 – Ameresco, Inc., (NYSE: AMRC), a leading energy efficiency and renewable energy company, today announced that the 2019 Environmental Initiative Awards have recognized Ameresco customers Minnesota State University, Mankato and the City of Mankato for their leadership in sustainability initiatives and efforts to pursue sustainable business practices and offer climate change solutions.

As part of the university’s drive to reduce its carbon footprint, it entered into an $8.1M energy savings performance contract with Ameresco in the fall of 2017. Through this budget-neutral financing model, Minnesota State University, Mankato pursued energy efficiency upgrades for 31 campus buildings as well as sidewalks and roadways.

On behalf of the university, Ameresco completed a variety of measures, including: extensive LED lighting retrofits, LED interior and exterior lighting improvements, campus‐wide building automation controls optimization and central plant boiler plant system enhancements. Combined, these efforts are expected to result in more than $400,000 in annual energy savings.

In addition to the university, the Environmental Initiative Awards also recognized Ameresco customer the City of Mankato, Minnesota. The City of Mankato earned an honorable mention in the energy and climate category. Since 2017, Ameresco has partnered with the City to upgrade facility LED lighting and LED street lighting; pursue water conservation; improve building envelope, mechanical insulation and building automation; and replace boilers. Additionally, the City of Mankato and Ameresco developed a strategic capital plan that measured levels of deferred maintenance and risks associated with aging infrastructure. The City’s strategic capital plan is now a dynamic plan via Ameresco’s Asset Planner^TM software platform and provides a Decision Development Framework^TM for the City. Asset Planner^TM enabled the City to enhance its decision making capabilities by intersecting Capital Planning (predictive life cycle forecasting data) with Operational Expenditure savings information to optimize its investment strategy.

The City of Mankato is generating more than $259,000 in energy savings annually due to these Ameresco-led initiatives.

“Minnesota State University, Mankato and the City of Mankato have both taken bold steps to reduce their carbon imprint,” said Louis Maltezos, Executive Vice President, Ameresco. “The foresight to pursue an energy savings performance contract has already proved economically beneficial, and now it is a pleasure to see both the university and city recognized for their broad, long-standing commitment to sustainability. Congratulations to the Mavericks.”

Minnesota State University, Mankato and the City of Mankato were formally recognized at the Environmental Initiative Awards ceremony, which took place in May.
