State-by-State Benefits from New Furnace and Boiler Standards (2007)
The tables available at the links below show ASAP's updated estimates of the potential energy and economic benefits from new furnace and boiler standards for each of the fifty states. See the notes below the links for key assumptions and explanations of the tables.
Economic benefits: Economic benefits are expressed as a net present value (NPV): This figure expresses in current dollars the cumulative value to consumers of the standard taking into account estimates of increased first cost due to efficiency improvements and lifetime energy bill savings. We use U.S. DOE's estimate of first cost increases where available and account for benefits and costs accrued from equipment installed between 2012 and 2030. This analysis uses 2005 state level average natural gas and fuel oil prices and assumes those prices stay constant over the analysis period.
Gas furnaces: The energy savings table shows savings achieved at two levels: DOE's proposed standard of 80% Annual Fuel Utilization Efficiency (AFUE) and the ASAP-supported level of 90% AFUE. Economic savings are shown for the 90% level for those states where ASAP's analysis shows this level to be cost-effective (all but five states). The analysis takes into account GAMA state-by-state sales data for 90% or better equipment (i.e. some consumers already are purchasing 90% or better equipment and their savings are not counted in this analysis as resulting from the standards policy.)
Furnace fans: The tables show savings from a standard requiring efficient furnace fans used for distributing warmed air through a home's duct system. This equipment is not included in the current DOE rulemaking, but could be addressed by a future DOE rulemaking. Some states have standards requiring efficient furnace fans.
Gas and oil boilers: The savings here are based on the joint GAMA/efficiency advocate recommendation to U.S. DOE. GAMA represents the boiler manufacturers. These savings are roughly double those achieved by the DOE-proposed standard.
Oil furnaces: Savings shown are those that would be achieved by an 83% AFUE standard. DOE has proposed an 82% AFUE standard. The DOE proposal would achieve about half of the savings estimated here.
