The Apogee HomeEnergyCalculator™ (HEC) and CommercialEnergyCalculator™ (CEC) are Web-based energy use analysis applications that enable users to understand what drives energy use with annual and monthly load disaggregation, provide data to see how their energy use compares to peers, and enable scenario analysis to screen likely savings strategies.

Energy use and savings analysis.
The underlying algorithms are the same that are the platform for Apogee’s advanced onsite audit applications, which are about to be submitted for certification by RESNET. Results are expected in the Summer of 2009.
No special training is required – simple inputs are all that are required.
The HEC is currently providing energy analyses on over 500 utility Web sites to thousands of homeowners daily.
HEC: homeowners. CEC: onsite or headquarters facility managers for commercial buildings
HEC inputs typically number about 25, depending upon the host’s configuration choices, and most are drop down selections. Typical inputs are home style, size, year built, number of occupants, location (usually determined by host), comfort set points, and some appliance stock details. The program downloads actual weather automatically from a nearby weather station. Utility rate schedules are normally set up during implementation. Inputs for the CEC are similar but also include business type, hours of operation, and more detail on equipment.
Outputs include annual and monthly disaggregated use, recommended changes to save energy with savings estimates, monthly comparisons with reasons for variations, peer comparisons, and carbon footprint. For the initial home configuration and for each savings scenario explored.
The applications are accessible over the Internet.
The HEC and the CEC are best used to engage homeowners and business operators in energy options exploration. More sophisticated Apogee applications are used for onsite audit support and ongoing usage tracking with alert/alarm functionality.
