EIS Case Studies:

EIS Case Studies University of California-Santa Barbara (2000-2001) $341,500 upfront costs Identified exhaust fans left running, fan hoods left open, covers left off pool Electrical energy use reduced by 13.8% Electrical peak demand reduced by 16% Natural gas usage reduced by 10% Participate in demand relief programs $590,000 in costs saved $295,00 attributed to EIS Payback < 1 year

EIS Case Study:

EIS Case Study University of California-Merced (2005), identified improper broiler operation, $2,500/month saved Sysco (2005-2008), found lights left on after hours, performed retrocommissioning and tune-ups, 18% reduction in portfolio energy use UC- Berkley,found excessive vetillation & over illumination, 30% reduction in whole building energy use Wal-Mart, found 225 kW static load due to malfunctioning dimmer switch, $35,000/ year
