Additionally, burn hours were assumed through information provided by county personnel, industry standards, and site data collection. These variables were used to calculate the electricity consumption and demand savings from reducing lighting wattage. Electrical demand savings (kW) were determined by comparing the wattage of existing fixtures with the wattage of proposed fixtures and then applying a diversity factor, as shown in the equation below. The diversity factor represents the likelihood of that fixture being energized during the period that peak demand is typically set. kWsavea = # of Months X [(kWBase — kWRetro) X Diversity Factor %] /ir,rzGiii///,o¢,;r/r////1%"ic7iiir0'i;,i„• / ;„iiririir ;,iirrrrl:-i m�, l/, %%/// �%///%1 ii/ Hendricks County, IN March 20'^, 2019 ZZ City of South Bond - August 27, 2136 11.
