An Energy Saver Called NECAP

NASA computer program NECAP, used by Stearns-Roger, Inc., is an energy analysis computer program which considers the many factors related to energy-saving design features for new building or modifications to existing facilities. Program enables examination of a multitude of influences on heat flow into and out of buildings. NECAP considers traditional weather patterns for a given local and predicts the effects on a particular building design of sun, rain, wind, even shadows from other buildings. Takes into account the mass of structural materials insulating values, type of equipment the building will house, equipment operating schedules, heat thrown off by people and machinery, heat loss or gain through windows and other openings and a variety of additional details. NECAP also determines cost effectiveness and whether an energy saving measure will pay back its installation cost through monetary savings in energy bills.
