What Does it Do?
Jason TURGEON
Uses 1999 Commercial Building Energy Consumption Survey (CBECS) dataCompares subject building to similar buildingsProvides a statistically normalized score from 1 to 100Calculates annual energy use intensity (kBtu/sq. ft)Normalizes data for weather and climateSecurely hosts user’s database of building data
