Case Study on The California State University of San Bernardino
The 38,000 square foot fitness facility on campus had 20 machines
retrofitted with ReRev back in 2009.
This fitness center uses approximately 2,100 kilowatt hours of
electricity per day.
Energy Impact– Page 43
The estimated kilowatt hours per square foot used for one day
was found to be approximately 0.055 kWh/SF.
The kilowatt hours used daily at VIDA comes to approximately
3336.24 kWh/day or 1,217,726.45 kWh/year.
The percentage of energy generated was estimated to be 5.76%.
Greater than 5% in Renewable Energy Generation adds an
additional 3 points to the LEED Scorecard making VIDA
applicable for LEED Gold
