Performance Graphs for Solar-Savings Fraction Vs. Load-Collector Ratio for Selected Cities in the South

摘要

A graphical presentation is provided of Solar Savings Fraction (SFF) versus Load Collector Ratio (LCR) for 14 southern cities. Individual plots are shown for five standard passive systems: direct gain, Trombe wall, water wall, Type A sunspace, and Type B sunspace. Both uninsulated and night-insulated systems are considered for a total of ten plots per site. Instructions for using the graphs to estimate Solar Savings Fraction and annual auxiliary energy consumption are also included. (ERA citation 07:043014)
