St Regis
Aspen, Co
With its 1,420 evacuated tubes, this solar thermal system was the second largest on a commercial building in the United States at the time of install. Output from the system ranges from 1 to 2.5 million BTUs per day, depending on the time of year. In less than a year, the St. Regis has reported an energy savings of $80,000. This savings, coupled with rebates, grants, and incentives puts their return on investment under 2 years! This means that the savings for the rest of the system’s lifespan (18 to 28 years) is money earned.
