1.1 Program Capabilities

TREAT is an interactive program that allows its users to accomplish the following tasks:

• Create a multi-zone energy model of single-family or multi-family buildings.
• Calculate the monthly cost of each fuel used in the model for typical weather conditions.
• Analyze improvements for the building and group these improvements in packages.
• Account for interactions of improvements in the packages.
• Calculate design heating and cooling loads for the model and each evaluated package of improvements.
• Calculate projected energy savings from individual improvements and improvement packages in Btu and dollars.
• Calculate payback, SIR (Savings to Investment Ratio) and annual cash flow for each improvement and package of improvements.
• Present a work scope for a selected package of improvements, including basic cost estimation.
• Print reports for customers that encourage investing in improvements, including information on building performance.
• Analyze utility bills for multiple fuels and meters in the building.
• Estimate usage for the missing utility bills.
• Track energy use after the improvement package is installed.
• Weather-normalize actual utility bills and calculate the base load (non-heating usage) for each fuel.
• Calibrate the model to match calculated monthly energy usage to actual billing data.
• Create a database of clients (customers).
• Save filtered lists of customers in ASCII format, for use in mail-merges for follow up letters and marketing.
