## Federal Appliance Manufacturing Standards	and	State Residential Building Energy Codes

- Jean J. Boulin
- Building Technologies Program
- U.S. Department of Energy

## DOE issued standards for central air-conditioners and heat pumps effective January 23, 2006 
These standards preempt state and local building codes and regulations that differ from these standards
Recommend review and updating of residential building energy codes  to reflect these standards.

- These standards preempt state and local building codes and regulations that differ from these standards
- Recommend review and updating of residential building energy codes  to reflect these standards.

**Notes:**
The Department of Energy issued residential appliance manufacturing standards for central air-conditioners and heat pumps that took effect on January 23, 2006. 
These standards preempt state and local building codes and regulations that differ from these standards.  (See 10 CFR 430.33.) 

##  10 CFR 430, Subpart C – Preemption

- Sec. 430.33  Preemption of State regulations.
- 		Any State regulation providing for any energy conservation standard, . . . with respect to the energy efficiency, energy use, . . . of a covered product that is not identical to a Federal standard in effect under this subpart is preempted by that standard, . . ..

**Notes:**
TITLE 10--ENERGY

CHAPTER II--DEPARTMENT OF ENERGY

PART 430  ENERGY CONSERVATION PROGRAM FOR CONSUMER PRODUCTS 
Subpart C  Energy and Water Conservation Standards

Sec. 430.33  Preemption of State regulations.
    Any State regulation providing for any energy conservation standard, or water conservation standard (in the case of faucets, showerheads, water closets, and urinals), or other requirement with respect to the energy efficiency, energy use, or water use (in the case of faucets, showerheads, water closets, or urinals) of a covered product that is not identical to a Federal standard in effect under this subpart is preempted by that standard, except as provided for in sections 327 (b) and (c) of the Act.
[63 FR 13318, Mar. 18, 1998]

## Appliance Standards

- Recommend review and updating of residential building energy codes  to reflect these standards.
- Residential-sized central AC & HP manufactured or imported on or after January 23, 2006
- Increased SEER and HSPF
- Equipment manufactured before January 23, 2006 can continue to be sold
- If IECC or IRC 1998, 2000, 2003 or MEC 1995 and earlier are included in state codes – criteria  are superseded by new standards

**Notes:**
Residential-sized central air conditioners and heat pumps, manufactured or imported on or after January 23, 2006 
Increased minimum Seasonal Energy Efficiency Ratio (SEER) and minimum Heating Seasonal Performance Factor (HSPF). 
Equipment manufactured to the current standard, before the January 23, 2006 effective date, can continue to be sold. 
We believe that the 1998, 2000, and 2003 editions of the IECC, the 2000 and 2003 editions of the IRC, and the 1995 and earlier editions of the MEC contain minimum equipment performance requirements that, if included in state codes, will be superseded by these new standards 

## TABLE 503.2 MINIMUM EQUIPMENT PERFORMANCE

| EQUIPMENT CATEGORY | SUBCATEGORY  | MINIMUMf |
| --- | --- | --- |
| Air-cooled HP Htg. mode < 65,000 Btu/h capacity  | Split systems
Single package | 6.8 HSPF  7.7 HSPF a, b
6.6 HSPF  7.7 HSPF a, b |
| Gas- or oil-fired furnace < 225,000 Btu/h  | __  | AFUE 78% 
Et 80% |
| Gas- or oil-fired steam & hot-water boilers < 300,000 Btu/h | __  | AFUE 80%  |
| Air-cooled HP Clg. mode < 65,000 Btu/h capacity | Split systems
Single package  | 10.0 SEER  13.0 SEER b
  9.7 SEER  13.0 SEER b |

**Notes:**
The existing equipment that is preempted is shown on this slide with the preempted criteria struck through and the new criteria in red bold.  There are also new  subcategories of through-the-wall systems, both split and single package show on subsequent slides.  

## Recommended Footnotes to TABLE 503.2 

- b. This is used to be consistent with the National Appliance Energy Conservation Act (NAECA) of 1987 (Public Law 100-12), as amended.
- f. Heat pumps manufactured before January 23, 2006 may have a HSPF of 6.8 for split systems and 6.7 for single package units, and air-conditioners manufactured before January 23, 2006 may have a SEER of 10 for split systems and 9.7 for single package units.   Trade-offs between equipment and other building components are not allowed for equipment that does not exceed the minimums in this table.

**Notes:**
Manufacturers and distributors will continue to sell units manufactured to the pre-January 23, 2006 standards prior to the effective date of the new standards, as the DOE appliance standards are manufacturing standards, not standards limiting the sale of products.  Distributors and contractors will have inventories of this pre-January 23 manufactured equipment and could be financially impacted if this equipment is suddenly not permitted to be installed.  We therefore recommend that provision be made to permit installation of that previously manufactured equipment which is sold subsequent to the effective date of the standard.  One way this can be done is by inserting footnote (f) to specifically allow such equipment.  However, since NAECA requires the baseline for codes to be the NAECA equivalent, it is recommended that trade-offs not be allowed for equipment that does not exceed the minimums listed in the table.  This will avoid penalizing installation of equipment manufactured to the pre-January 23, 2006 standard, and sold after the effective date of the new standard. Otherwise, with the new higher baseline, use of equipment manufactured to the pre-January 23, 2006 standard in an envelope trade-off would result in requiring a better performing envelope to offset the lower performing equipment.

## Compliance Manuals , Software, etc.

- Don’t forget other materials that reference central air conditioning efficiency levels – update them too

**Notes:**
Should a state or local jurisdiction maintain compliance manuals, software, or other materials that reference central air conditioning efficiency levels in connection to building energy code compliance, we recommend that these materials be updated to reflect the new SEER and HSPF standard as the specification to use in all baseline or reference building designs.

## TABLE 503.2 MINIMUM EQUIPMENT PERFORMANCE

| EQUIPMENT CATEGORY | SUBCATEGORY  | MINIMUM |
| --- | --- | --- |
| Air-cooled HP Htg. mode < 65,000 Btu/h capacity  | Through-the-wall split sys.
Through-the-wall single pckg | 7.1 HSPF a, b
7.0 HSPF a, b |
| Gas- or oil-fired furnace < 225,000 Btu/h  | __  | AFUE 78% 
Et 80% |
| Gas- or oil-fired steam & hot-water boilers < 300,000 Btu/h | __  | AFUE 80%  |
| Air-cooled HP Clg. mode < 65,000 Btu/h capacity | Through-the-wall split sys. g
Through-the-wall single pckg g | 10.9 SEER b
10.6 SEER b |

**Notes:**
Two new categories have been established for through-the-wall units.  It is not necessary to include these two new categories in an amended table. The designation of “single phase” should be added to the residential Equipment Category to distinguish it from three phase commercial equipment of the same designation, which is not covered by the residential appliance manufacturing standards. 

## Recommended Footnotes to TABLE 503.2Added Subcategories

- g. These requirements apply to through-the-wall products with cooling capacities less or equal to 30,000 Btu/h manufactured prior to January 23, 2010.
