SIMPLIFIED ENERGY ANALYSIS OF RESIDENCES

摘要

We have designed a software package called PEAR (Program for Energy Analysis of Residences), which is written with userfriendly input and output and runs on the IBM PC. PEAR provides an easy-to-use and very fast compi lation of a comprehensive DOE-2.1 data base for residential buildings. The current version, which covers five residential building prototypes in over 800 locations, estimates energy and cost savings resulting from typical conservation measures such as ceiling, wall and floor insulation, window type and glazing layers, infiltration levels, and equipment efficiency. It also allows the user to adjust for optional measures including roof or wall color, movable insulation, whole-house fans, night temperature setback, reflective or heat absorbing glass, thermal mass in exterior walls, and two attached sunspace options. The program is designed to be used both as a research tool by energy and policy analysts, and as a non-technical energy calculation method by architects, home builders, home owners, and others in the building industry.
