A simple PC spreadsheet program that estimates the total annual heating and cooling energy consumption of conventional
houses in over 800 locations, using a database of thousands of DOE-2 computer simulations. PEAR (Program for Energy
Analysis of Residences) Version 2.1 calculates the cost-benefit of conservation measured depending on user-input base case
condition and costs. Used by architects and engineers to analyze the energy efficiency of house designs; used by utility
companies and energy offices to evaluate retrofit measures; used by universities to teach energy-efficient design.

Audience
Architects, engineers, energy consultants, utility companies, state and federal agency staffs, university faculties of architecture and engineering.
Input
General building description, including building type, areas and amounts of insulation of walls and roofs, amount of air leakage, type and areas of windows, perimeter length, efficiency of space conditioning system, and building location.
Output
Total annual heating and cooling energy use, and their breakdown by building component, e.g., walls, roofs, etc.
