Average Eco-rating

Average Eco-rating: A product's balance between environmental and economic considerations. The product that has the highest Average Eco-rating is both environmentally preferred and cost-effective to purchase and own.
 75
Environmental Impact Rating: based on average amount of energy (kWh) consumed per year and average annual emissions of CO2 (calculated according to the average emissions associated with the production of each energy source, e.g. electricity, natural gas, etc.). The higher rating, the more energy-efficient and less-emitting the technology is of CO2.
71
Consumption Rating: based on average annual kilowatt hours consumed for each technology. The higher the rating, the less energy-consuming and more efficient the technology.
32
Lifecycle Cost Rating: based on average annual cost of operation (energy expenses) over an 18-year period plus average purchase price, including installation and 2009 Federal tax credits. The higher the rating, the more cost-effective the technology.
97
Price Rating: based on average purchase and installation prices for each technology, including the 2009 Federal tax credit, if applicable. The higher the rating, the lower the price of the technology.
100
The higher the rating, the better.

Our Environmental Impact Rating for the Heating & Cooling Technology Category is based on the technology's average annual emissions of CO2. Annual CO2 emissions are calculated according to the average emissions associated with the production of each energy source (e.g. electricity, natural gas, etc.) and the average amount of energy consumed per year for each technology.

The higher the Environmental Impact Rating, the less-emitting the technology is of CO2 emissions due to its energy source (higher rated technologies burn cleaner fuel) and efficiency.

Our Consumption Rating for the Heating & Cooling Technology Category is based on average annual kilowatt hours consumed for each technology. The higher the Consumption Rating, the less energy-consuming and more efficient the technology.

Our Lifecycle Cost Rating for the Heating & Cooling Technology Category is based on the technology's average annual cost of operation (energy expenses) over an 18-year period plus its average purchase price, including installation and 2009 Federal tax credits. The higher the Lifecycle Cost Rating, the more cost-effective the technology.

Our Price Rating for the Heating & Cooling Technology Category is based on average purchase and installation prices for each technology, including the 2009 Federal tax credit, if applicable. These prices are rough estimates; contact your local HVAC contractor for accurate prices.

The higher the Price Rating, the lower the price of the technology.
