ECONOFROST Night Covers at 6 hours a day compared to no Night Covers
| 720 Feet | 1 Year Savings | 10 Year Savings | |
| Electricity | $28,154 | $28, 540 | |
| Lbs. of CO2 | 341, 948 | 3, 419, 480 | |
| Cars Removed for 1 year | 32.27 | 322.70 | |
| Planting "x" acres of trees | 53.09 | 530.90 |
Energy Saved Per Year, Compare the difference with an integrated night cover
| Without night covers | 1,385 BTU/feet | |
| With night covers | 831 BTU/feet | |
| Savings | 554 BTU/Feet |
| Conversion to KWh per foot | 554 BTU*0.000293 | = 0.162322 kWr/feet | |
| Number of feet in a type store | 720 Feet | = 0.16 kWr * 720 feet | |
| KWh saved per store per hour | 0.16 kWr * 720 feet | = 116.87 kWh | |
| KWh saved per store per day | 116.87 kWr * 6 hours | = 701.23 kWr/day | |
| kWr saved per store per year | 701.23 kWr/day * 365 days | = 225.949.32 kWr/year |
Further savings to the environment
| Dollars per year per store of electrical savings | 225.949.32 kWr/year * 0.11/kWr | = $28, 154.43 | |
| Lbs of CO 2 saved per year per store | 225.949.32 kWr/year * 1336 lb. CO2/1000 kWr | = 341, 948 lbs.CO2/year | |
| Equivalent Number of cars removed per year per store | 341, 948 CO2/year divided by 10,597 lbs. CO2/year | = 32.27 cars | |
| Equivalent to planting x number of acres per trees | 225.949.32 kWr/year * 1.4 acres/6750 kWr | = 53.09 acres/year |
| Conversion Factors | Sources |
| Watts to BTU multiply by 3.413 | 1, 000 kWr = 606 kg CO2 |
| BTU to kWr multiply by 0.000293 | 13, 000 miles per year at 24 mpg |
| Watts to kWr multiply by 0.001 | 6, 750 kWr = 1.4 acres of trees |
