Developed in collaboration with Jim Hoff, TEGNOS Research Inc., this paper provides a comparative overview of base use and peak demand of electricity and shares information on how to calculate peak demand savings. The role of cool roofing in promoting energy efficiency is also emphasized, particularly in respect to the unique performance properties of reflective roof coatings. The document can also be viewed as a resource as to the benefits reflective roof coatings provide to buildings, businesses, and the environment at large.
A sharp peak in electrical demand can be observed in almost every building during the busiest hours of the day. Although a portion of this peak may be attributed to lighting and equipment used in the building, the majority is caused by the increased demand for air conditioning in the heat of the afternoon. In an effort to help building owners and designers deal effectively with peak electrical demand charges, this white paper provides a step-by-step review of all aspects of peak demand, including how to identify peak demand charges on a typical commercial electrical bill, how to estimate the potential savings achieved when installing a reflective roof coating, and how to achieve other business and community benefits associated with reducing peak energy demand.
