Honeywell Conducts Campus-Wide Energy Audit
In 2012, Honeywell, a global technology leader in energy efficiency, performed an energy audit of the Colby-Sawyer campus to evaluate building efficiency and reduce the amount of energy consumed.
Honeywell began by collecting three years' worth of raw consumption data to establish a baseline average usage for electricity, LP gas (the predominant heating fuel used on campus), and fuel oil, which is in a handful of the smaller, more residential buildings. Honeywell then worked with Colby-Sawyer to establish an agreed upon cost per energy type by looking at what the college was spending and how much the college was willing to invest.
The company surveyed over thirty buildings and installed data loggers that kept track of lighting usage, heating/ventilation motor function, and temperatures. They also inspected water and sewage devices to evaluate potential opportunities for increased efficiency and savings.
Colby-Sawyer and Honeywell discussed additional factors that might be contributing to low efficiency, such as poorly insulated windows and timing lags in the computer monitoring that switches building systems to unoccupied mode after periods of inactivity.
Initiatives Save Energy and Money
After months of planning and meetings between Honeywell, Colby-Sawyer's Director of Sustainability, Jennifer White '90, and Vice President of Administration, Doug Atkins, the college was able to purchase and implement new, more sustainable equipment.
Over the course of the project, Colby-Sawyer spent $1.1 million on improvements, which will pay for themselves in under ten years through the amount saved on energy costs. Monthly expenditures also remained the same and the savings helped offset project payments. A portion was also covered by a $150,000 New Hampshire Pay for Performance grant. According to the Pay for Performance, the program comprehensively addresses the energy efficiency needs of the commercial, industrial, and municipal government sectors by working with participants, such as developers, building owners and their representatives, to improve energy efficiency of commercial and industrial buildings.
It was the largest buildings on campus that received the most investment in energy conservation. Hogan Sports Center received new light fixtures, ballasts, and lamps that reduced lighting power by 35%," explained Jim Lucy, Energy Solutions Leader for Honeywell. "Colgate Hall received over 1,000 square feet of new insulation.
With the help of Honeywell and New Hampshire Pay for Performance, Colby-Sawyer transformed many buildings into more energy efficient and sustainable spaces that should save the college close to $150,000 annually. While the initial cost may be daunting, the long-term benefits of investing in energy efficiency, renewable resources and sustainability are undeniable and vital to ensuring the environmental stability of the planet.
