In letters to Julia Hegarty, in DOE's Building Technologies Office, Air Conditioning Contractors of America opposed phase-out, while Air Conditioning Heating and Refrigeration Institute, offered mild, and qualified, endorsement..
New standards, if adopted, would apply to furnaces manufactured in U.S., or imported, starting five years after the date the rule is published..
According to DOE analysis, the energy savings, reduction greenhouse gas emissions, and health benefits of the proposed standards would outweigh the costs.
DOE also said that consumer who replaces furnace with condensing model could save about $60 utility costs, and that the proposed standards would reduce CO2 emissions by 373 million metric tons over 30 years...
In his letter, ACCA's and CEO, Barton James, said that condensing furnaces have to be vented than noncondensing models, requiring building modifications that will end up costing consumers.
including equipment sizing, duct re-design and sealing, and appropriate refrigerant charges, efficiency improvements of 25% to 30% would result, ..
In to Hegarty, Laura Petrillo-Groh, AHRI's of regulatory affairs, said that.
in letter, Petrillo-Groh objected to AFUE standard for furnaces mobile homes, arguing that DOE had not factored in its energy-conserving construction standards for mobile homes that will take effect beginning next June, years before standard would kick in.
The construction standards will decrease in those mobile homes, therefore decreasing the energy savings that could be expected with the use of higher-efficiency furnaces and weakening the economic case for mandating them..
By state or other agencies should be excluded from counting against that limit, Petrillo-Groh's letter proposed that any electricity that's drawn by control and safety devices required by UL or..
