Energy Calculation Programs
Most of these programs have demonstration capabilities on their web sites.
(A Simplified Energy Analysis Method) Version 5.0 evaluates high-potential, cost effective energy efficiency projects in existing Federal buildings; calculates results that are within 4-5% of DOE-2 annual energy results, using quick input routines, permits evaluation of a 10,000 sq. ft. building in about 10 minutes.

Performs hourly simulations of buildings, air handling systems, and central plant equipment in order to provide mechanical, energy and architectural engineers with accurate estimates of a building's energy needs. BLAST output may be utilized in conjunction with LCCID (Life Cycle Cost in Design) program to perform an economic analysis of the building/system/plant design. From $575 to $950.

Hourly, whole-building energy analysis program calculating energy performance and life cycle cost of operation. Can be used to analyze energy efficiency of given designs or efficiency of new technologies. Other uses include building demand-side management and rebate programs, development and implementation of energy efficiency standards and compliance certification, and training new corps of energy-efficiency conscious building professionals in architecture and engineering schools. High level of computer literacy required. From $300 - $2000.

Energy calculation program also by Elite Software. An easy to use version of the Department of Energy's DOE program. Calculates hourly energy use and a building's life cycle cost of operation by using location, construction, operation, and heating and air conditioning system. Simulates all types of heating and cooling plants and allows for complex utility rate structures and other costs to be analyzed. Demonstration available on website www.elitesoft.com/hvacr/elite_ezdoe $1250.
