Affordable Housing through Energy Conservation: A Guide to Designing and Constructing Energy Efficient Homes: PEAR (Program for Energy Analysis of Residences) 2.1 User's Manual.

摘要

PEAR is an interactive program for residential building energy analysis utilizing a comprehensive DOE-2.1 data base for residential buildings. This data base was compiled using over 10,000 computer simulations covering five residential buildings in 45 geographical locations. This extensive data base is used by PEAR to estimate the annual energy use of houses with typical conservation measures such as ceiling, wall, and floor insulation, different window types and glazing layers, infiltration levels, and equipment efficiency. It also allows the user to include the effects of roof and wall color, movable night insulation on the windows, reflective and heat absorbing glass, an attached sunspace, and use of a night setback. Regression techniques in PEAR permit adjustments for different building geometries, window areas and orientations, wall construction, and extension of the data to over 800 US locations based on climate parameters. PEAR is designed as a user-friendly program that can be used both as a research tool by energy policy analysts, and as a nontechnical energy calculation method by architects, homebuilders, homeowners, and others in the building industry. Technical documentation of the PEAR program and the database is given elsewhere (see References). 3 refs., 11 figs., 5 tabs.
