Spend $600 now and SAVE $238 each year... ROI = 39.7%
Since about 40% of your small business energy costs go toward heating and cooling, you can save between 5% to 15% of that cost by sealing ducts and also insulating them from losing the warm heating air or the cool air conditioning as it travels to each office. The average US cost per employee for heating and cooling is $238 per year.
So, an average 2,500 sq. ft. office with ten employees spends about $2,380 per year on heating and cooling. Increase the insulation on your ducts to a minimum of R-6. It is important to conduct a thorough air sealing before adding insulation, as the new insulation may make some air leaks difficult to access. The insulation itself typically will not stop these leaks. Air flowing through the insulation will waste energy. Moist air can damage the insulation and reduce its effectiveness. The ROI Calculation is based on spending $600 and saving 10% on heating and cooling bills for an office with ten employees.
