APOGEE has developed a number of interactive calculators that are easy to use and focused on specific questions on residential and commercial energy issues. These calculators are characterized by the ability to change many variables using on-screen sliding buttons. Changes in settings give immediate visual feedback - charts and values change as settings are modified. The results can also be expressed in different practical terms, including total annual dollars saved or total ownership cost savings over10 years. Also included is the impact on the environment in carbon savings.

As with APOGEE's signature on-line energy efficiency tools, these mini-calculators use local weather, energy costs, and technologies. These calculators are personalized to your utility's needs, appearance, and function. They operate in a public-facing mode outside of a utility's billing system.

APOGEE offers a number of mini-calculators, including:

• Lighting
• Appliance (including comparison with Energy Star® appliances)
• SEER (Seasonal Energy Efficiency Ratio)
• HVAC
• TV
• Set-back Thermostat
• Lift-Truck

One of the primary advantages of these calculators is APOGEE's ability to quickly customize and implement the calculators to the utility's specific needs. Clear answers can be provided to very specific questions. Parameters can be easily changed with immediate visual results. These calculators can be used for high-level energy assessments, environmental awareness, or marketing strategies. Links to one or more calculators can be grouped on a single page on the utility website or distributed throughout the utility website. Multiple links can be employed as well.

These calculators can be a key element of a utility marketing program.
