Case Studies: Commercial Energy Savings in Iowa

Iowa has a long and successful history of investments in energy efficiency.  To demonstrate the positive economic impacts energy efficiency has to Iowa businesses, MEEA has created a series of case studies showcasing businesses that have benefited from the financial rebates and guidance offered by the utility sponsored programs. These one-pagers highlight the savings and positive return on investment achieved by these Iowa businesses.

Springboard Engineering—Insulation Upgrades

After moving into their 1970’s era office, Springboard Engineering realized that in order to improve the comfort of their workplace environment and lower their operational costs, they needed to increase their building’s efficiency. After submitting their proposal to Black Hills Energy’s Commercial Custom Program, they qualified for an $8,100 rebate to help offset the cost of the project. With help from Black Hills energy they applied polyurethane foam to the roof as well as a reflective coating to reduce the roof’s temperature. Together, the upgrades saved Springboard Engineering $11,000 in annual energy costs.
