Cost Savings

If the district continued building all schools like the Generation #1 Goshen @ Hillcrest model, the district would have spent $638,000 per year on energy Based on Goshen Elementary energy costs of $1.32/sf * total

square feet of six newest buildings in district - 485,116 sf

Since the district has improved the building envelope, MEP systems and facility operations, energy costs was only $434,000 per year Average $.90/sf combined

Energy Savings of $204,000 per year! 37
