Spend $30 now and SAVE $6 each year... ROI = 20%
Break room equipment like Refrigerators, Microwaves, and Vending Machines account for about 4% of an office's energy costs. ENERGY STAR® qualified refrigerators use at least 10% less energy than required by current federal standards, and 40% less energy than the conventional models. The higher efficiency adds up to total office energy savings of 15 to 20%. Overall, you can use between 10-50% less energy with ENERGY STAR® qualified appliances, depending on the age of the refrigerator that your are replacing.
As an example, a new refrigerator may cost well over $850 and the annual energy savings is about $120. An ENERGY STAR® qualified refrigerator is only slightly more expensive than purchasing a comparably sized 'non-qualified' unit, so the added cost pays off relatively quickly.
This ROI Calculation is based on the marginal saving of just $.50 a month. If you are replacing a significantly older refrigerator, the savings will dramatically increase.
