Energy Audit - Residential/Light Commercial Energy Analysis

Giving Your Customers the Knowledge they Need

Energy Audit allows you to show homeowners precisely how much that new, efficient condensing unit will save them in utility bills. You can present homeowners with several choices of air conditioning and heating equipment, and create comparison scenarios that let them make a decision that they will be confident is the right one.



The Energy Audit program calculates monthly and annual heating and cooling costs for residential and light commercial buildings. Virtually any type of cooling and heating system can be simulated by Energy Audit including standard DX, evaporative, air source heat pumps, water source heat pumps, direct exchange heat pumps, and all types of fossil fueled furnaces and boilers including two stage and modulating boilers. An optional version of Energy Audit with appliance capabilities can calculate appliance and hot water energy use as well. Still another option available is for utility companies that want to show disaggregated past utility bills. Energy Audit uses heating degree days, weather bin data, and full load cooling hours in its calculations. Weather data for over 1500 cities throughout the world is built-in to Energy Audit and additional weather data can be easily added. Along with calculating energy costs, Energy Audit also performs an economic analysis that allows you to compare system types and costs over any given study period. There is even a loan, lease, and credit card analysis report designed to demonstrate affordability of better systems by showing that the effective net monthly cost is often very low when monthly energy savings are considered. To make system comparisons easy, Energy Audit allows you to manually enter equipment data or automatically look it up from ARI and GAMA equipment data files. Pictures for numerous equipment models are included as well. Energy Audit provides a wide selection of nicely formatted color charts, graphs, and reports.

Program Input

Two types of data are requested: general project data and specific HVAC system data. The general project data includes the project name and location, client information, fuel cost data, optional appliance data, and the design heating and cooling loads which can be automatically read from RHVAC or CHVAC. The HVAC system data includes specific information on the system type, model number, efficiency, cost, capacity, and fuel used. Energy Audit allows direct entry of the system data or the data can be automatically looked up from the included ARI/GAMA databases. An unlimited number of HVAC systems may be defined per project and each system can have a backup heating system specified as well. Economic data concerning initial system cost, interest and inflation rates, and loan amounts can also be entered. In order to minimize redundant input, Energy Audit can also import data from project data files created by the Elite Software RHVAC and CHVAC hvac load calculation programs.

Equipment Selection

Although you can manually enter system information on equipment from any manufacturer, Energy Audit also allows you to quickly select models from hvac manufacturer databases that are included with the Energy Audit program. Energy Audit can look up equipment data for all the manufacturers (over 200) whose products are listed with the Air Conditioning and Refrigeration Institute (www.ari.org) directory and the Gas Appliance Manufacturers Association (www.gamanet.org) By selecting a model number from one of the equipment databases, all the information for the model is looked up so that operating cost calculations can be automatically performed.

Program Output

Energy Audit provides numerous color presentation quality reports including a title page, project summary, system comparisons, appliance analysis, hot water heating, investment, loan, and lease analysis, line graphs, pie charts, and bar graphs. The reports can be previewed on screen, printed, or saved as a file. Any combination of detailed and summary reports can be selected for printing by the user. All reports reflect the input data that caused the calculated results. Shown below are just a few of the many reports and graphs that can be printed.
