Senate Panel Meets On Energy Efficiency Incentives
On December 12, the Senate Finance Subcommittee on Energy, Natural Resources, and Infrastructure held a hearing to discuss three proposals that would add or modify existing energy efficiency tax incentives for commercial buildings, homes, and industry. Dr. Dan Arvizu, Director, National Renewable Energy Laboratory; Steve Nadel, Executive Director of the American Council for an Energy-Efficient Economy; Mark Wagner, Vice President of Government Relations, Johnson Controls, Inc.; and Matt Golden, Principal,, and Policy Chair, Efficiency First, testified at the hearing. 

All of the witnesses agreed that reform must include performance-based tax incentives. Wagner stated that the needs of the commercial building sector and financing structures would be better served by incentives that are performance-based, technology-neutral and based on actual, verified performance. Nadel noted that well-targeted energy efficiency tax incentives will result in significant energy savings and will get more energy-efficient products into the market faster. In his testimony, Nadel suggested that Congress should continue to target federal support over a defined period of time (around five years) toward advanced technologies and practices that currently have a low market share to allow the technologies’ market share to grow and prosper on its own after the tax incentives end.

North Carolina Building Code Council Amends Proposed Energy Code
On December 10, the North Carolina Building Code Council voted unanimously to amend the proposed 2012 North Carolina Energy Code, as requested by AHRI, to avoid a conflict with the federal preemption provisions of the Energy Policy and Conservation Act. Before the amendment, the proposed Code would have required commercial HVAC equipment and water heaters to have efficiency ratings in excess of applicable federal and ASHRAE Standard 90.1 minimum efficiency standards unless the building had other energy conservation upgrades such as a tighter envelope. The AHRI-supported amendment provides that compliance with ASHRAE Standard 90.1-2010 will satisfy the North Carolina Energy Code as it applies to commercial buildings. The proposed Code will now go through the normal North Carolina administrative rulemaking process and is expected to be finalized in the first half of 2013. Contact: Amy Shepherd.

Massachusetts Developing Regulations to Reduce Refrigerant Emissions
The Massachusetts Department of Environmental Protection (MassDEP) and the Office of Technical Assistance (OTA) are assessing options to reduce refrigerant emissions from stationary refrigeration and air conditioning equipment. Under the Massachusetts Clean Energy & Climate Plan for 2020, published by the Executive Office of Energy and Environmental Affairs in December 2010, the state of Massachusetts is required to establish a statewide limit on greenhouse gas (GHG) emissions between 10 percent and 25 percent below 1990 levels by 2020, and an up to 80 percent reduction in emissions by 2050. The plan contains a portfolio of policies to reduce GHG emissions, including a policy intended to reduce refrigerant leaks from stationary refrigeration and air conditioning equipment. MassDEP conducted a public hearing on December 18, during which it indicated its intention to develop regulations to reduce refrigerant emissions similar to the regulations currently in place in California. A copy of the presentation made by MassDEP staff at the public hearing can be found here. MassDEP is expected to issue draft regulations in two to three months and will invite stakeholders to comment at that time. Contact: Karim Amrane

DOE Issues Proposed Rule on Petitions for Waiver/Interim Waiver for Consumer Products and Commercial/Industrial Equipment
On December 17, the U.S. Department of Energy (DOE) issued a notice of proposed rulemaking (NOPR) in the Federal Register that proposes amendments and corrections to petitions for waiver and interim waiver from DOE test procedures for consumer products and commercial and industrial equipment. In the NOPR, DOE proposes the following:
  • Restoring text (with minor amendments) that DOE inadvertently deleted while finalizing the March 7, 2011, final rule on certification, compliance, and enforcement. The language pertains to petitions for waiver and interim waiver of DOE’s test procedure requirements for consumer products.
  • A process by which, within 60 days after DOE grants a waiver for a product employing a particular technology, other manufacturers of that product employing a technology or characteristic that results in the same need for a waiver would submit a petition for waiver.
  • A process for manufacturers to request rescission or modification of a waiver if they determine that the waiver is no longer needed, or for other appropriate reasons.
  • Minor modifications to the waiver provisions for both consumer products and commercial equipment and to clarify certain aspects related to the submission and processing of a waiver petition.
The specific proposals to amend the waiver provisions can be found here. Contact: Aniruddh Roy.

AHRI Submits Comments Supporting the Extension of Compliance Dates for Certification of Commercial Products
On December 20, AHRI submitted comments in support of the Department of Energy’s (DOE) notice proposing to extend the compliance dates for the certification provisions of commercial HVAC, water heating, and refrigeration equipment. While supportive, AHRI’s comments noted that the proposed 12-month extension from the December 31, 2012, compliance date was not sufficient and should at a minimum be linked to the completion of the Alternative Efficiency Determination Method (AEDM) final rule. AHRI proposed an 18-month extension from the publication of the AEDM final rule for all commercial HVACR and water heating equipment. For commercial icemakers, AHRI requested an extension until June 30, 2013. DOE expects to finalize the rule by December 31, 2012. Meanwhile, AHRI wrote a letter to DOE’s Deputy General Counsel Timothy Lynch requesting that the agency issue written guidance that would state that the Department does not intend to proceed with any enforcement action if the final rule is not published by January 1, 2013. Contact: Karim Amrane.

DOE Seeks Input on Labeling Requirements for Commercial and Industrial Equipment
ThisOn December 20, 2012, the Department of Energy (DOE) issued a request for information (RFI) soliciting input from stakeholders on the potential for establishing labeling requirements for covered commercial and industrial equipment, including HVAC, refrigeration, and water heating products. The Energy Policy and Conservation Act (EPCA) authorizes DOE to develop labeling rules for any covered equipment for which the Department has prescribed federal test procedures.  However, DOE cannot prescribe such a rule unless it has determined that labeling would be (1) technologically and economically feasible for the class of covered equipment; (2) that significant energy savings would result from such labeling; and (3) that labeling would assist consumers in making purchasing decisions.  DOE is specifically looking for information on the following issues:
  • The economic and technological feasibility of prescribing  labeling requirements;
  • The extent to which labeling on commercial HVACR and water heating equipment would assist consumers in making purchasing decisions;
  • Whether a labeling requirement would result in additional energy savings;
  • Information that DOE should consider requiring for display on a prospective label;
  • Factors that DOE should consider regarding size, format and placement of labels;
  • Factors that DOE should consider regarding enforcement of any prospective labeling requirements.
DOE will accept comments until March 20, 2013.  AHRI will work with impacted product sections to develop an industry position. Contact: Karim Amrane.

AHRI International Committee Meets in Arlington
AHRI’s International Committee, chaired by Roger Richmond-Smith of Smardt Group, met at AHRI headquarters in Arlington, VA, on December 11. Members reviewed global developments regarding refrigerant choice, the regulatory creep of un-harmonized Minimum Energy Performance Standards (MEPS), and the negative effects of these developments on the global HVACR industry. The committee drafted its 2013 goals and initiated a review of AHRI’s refrigerant policy to determine whether any changes should be recommended to the AHRI Government Affairs Committee, which will meet on January 9.

AHRI Hosts Meeting with Intertek
Members of Intertek’s management staff visited AHRI headquarters on December 4 for a quarterly meeting to review certification program testing progress and to plan for 2013 testing. Currently, the 2012 completion rate stands at 90 percent, with about 1,900 tests out of 2,100 completed. Intertek and AHRI staff developed a 12-month outlook for 2013 testing that requires the timely delivery of testing samples to level the testing load at the lab throughout the year, and facilitate a 100 percent test completion rate by the end of 2013. To improve the efficiency of operations at its Cortland facility, Intertek is implementing a 5S audit process and a barcode scanning system that will assist with sample management and control. The meeting also included discussions on improvements to existing facilities, Intertek’s plans to invest in additional building capacity, and AHRI’s testing diversification goals. Contact: Bill Tritsis.

Congress Passes AHRI-supported Regulatory Relief and Stability
AHRI applauds Congress’s passage of H.R.6582, the American Energy Manufacturers Technical Corrections Act. The bill passed in the House of Representatives by a vote of 398 to 2 on December 4, and was passed by unanimous consent in the Senate on December 6. It now moves to the President’s desk for his signature, which is expected sometime before the Christmas break. The bill codified an appropriate service-over-the-counter standard, codified standards for small-duct high-velocity systems, established a timeline for a new energy descriptor and test procedure for water heaters, and corrected mistakes within the Energy Policy and Conservation Act. Contact: Guido Zucconi

Washington State Building Code Council Votes to Amend State Energy Code
On Friday, November 30, the Washington State Building Code Council voted to amend the proposed 2012 Washington State Energy Code, removing a provision that is preempted by federal law under the Energy Policy and Conservation Act (EPCA). The provision, section C406 of the Code, would have required compliance with at least one of four options in order to satisfy the commercial provisions of the Code, one of which was the installation of air conditioning, heating, and water heating equipment with energy efficiency performance levels in excess of federal requirements. Contact: Amy Shepherd.

AHRI Submits Comments on ASHRAE Standard 191P
On December 10, AHRI submitted comments on ASHRAE 191P, Standard for the Efficient use of Water in Building, Site, and Mechanical Systems. The purpose of the standard is to provide baseline requirements for the design of building site and mechanical systems that minimize the volume of water required to operate HVAC and other building systems. AHRI noted in its comments that many of the proposed provisions go beyond baseline requirements, however, and would be more appropriate in a “stretch” or “green” code. AHRI also suggested removing redundant energy efficiency requirements, which are already covered in existing efficiency standards and building codes, and more clearly identifying the building types covered by the standard. The Standards Project Committee 191 will review submitted comments on Sunday, January 27, from 9:00-11:00 am CT, at the 2013 ASHRAE Winter Conference in Dallas, Texas. Contact: Jon Lemmond.

EPA Issues Final Draft ENERGY STAR Commercial Water Heater Specification
On December 6, the U.S. Environmental Protection Agency (EPA) issued its Final Draft specifications for commercial water heaters. This Final Draft revises the initial draft that was issued by the EPA in August, and includes specifications applicable to commercial gas storage and instantaneous water heaters as well as a placeholder for commercial heat pump water heaters. The specifications for commercial heat pump water heaters will be added once an applicable efficiency test procedure is developed for those products. EPA requests that comments on the draft specification be submitted by December 20 EPA intends to finalize this specification by the end of the year and to implement the program immediately upon its finalization. Contact:Frank Stanonik.

Delegates to the Montreal Protocol Meet in Geneva
Delegates to the Montreal Protocol met in Geneva November 12-16 for the 24th Meeting of the Parties to the Montreal Protocol.  The U.S. and other parties continued to advocate for the addition of HFCs to the Montreal Protocol following concerns about the increasing use of high GWP HFCs as a replacement for HCFCs. The amendment received strong support from 108 parties, but was ultimately blocked by objections based on concerns that the Montreal Protocol does not cover non-ozone-depleting compounds, that alternatives have not been identified, and that developing countries are struggling to comply with the HCFC phaseout.  However, a discussion group allowed for an exchange of views among Parties to explore institutional framework, costs, financial support, and the availability of alternatives, bearing in mind that many questions related to the availability of alternatives were already being discussed under other agenda items.

DOE Extends Compliance Deadline for Certification Test Reporting
The Department of Energy (DOE) announced a 12-month extension for certification of all covered commercial equipment, with the exception of automatic commercial ice makers. AHRI will continue to work with DOE to ensure that the agency’s testing, certification, and reporting requirements do not unduly burden manufacturers. Watch the Video Update with Vice President of Regulatory and Research Karim Amrane.

Notice of Proposed Rulemaking (NOPR) extended the December 31, 2012, deadline by 12 months for manufacturers to certify and file specific performance information with the DOE for federally covered commercial equipment. DOE proposed not to extend the compliance date for automatic commercial ice makers as it is not aware of any issues that would prevent manufacturers from complying with the certification requirements by the end of the year. However, DOE invited stakeholders to comment on whether the compliance date should be extended. On the other hand, the compliance date for walk-in coolers and freezers has been in effect since October 1, 2011, and is not subject to this rulemaking. AHRI will work with affected sections to develop comments, which are due December 21. Contact: Karim Amrane.

External Scientific Peer Review Reports Available on California Consumer Product Regulations
On November 30, the California Department of Toxic Substances Control (DTSC) informed stakeholders that in accordance with the Health and Safety Code section 57004, DTSC has received several reports from external scientific peer reviewers.

CEC Conducts Title 24 Workshop on Alternative Calculation Method Reference Manual
On November 20, the California Energy Commission (CEC) conducted a workshop to present draft revisions and solicit public comment on the 2013 Residential Alternative Calculation Method (ACM) Reference Manual, as part of efforts to prepare for the implementation of the 2013 update to the Building Energy Efficiency Standards (Standards) (California Code of Regulations, Title 24, Parts 1 and 6). The CEC adopted the 2013 update to the Building Energy Efficiency Standards on May 31, 2012. A transcript of the workshop; presentations; and the latest draft ACM Reference Manual, algorithms, and compliance certificates can be accessed here. Although the November 20 workshop focused only on the performance compliance rules for newly constructed buildings, the CEC intends to conduct a separate workshop to discuss the performance compliance rules for residential additions and alterations. CEC staff is now developing the guidance documents and implementation tools for these standards. The 2013 Residential ACM Reference Manual documents the modeling rules that govern the implementation of the performance compliance approach in the compliance software tools. Written comments need to be submitted to the CEC’s Dockets Unit ( by December 12, and the following docket number should be included in the subject line: 12-BTSD-06. Contact: Aniruddh Roy.

SCAQMD Publishes Draft Final Air Quality Management Plan
The South Coast Air Quality Management District (SCAQMD) of California recently released its draft final 2012 Air Quality Management Plan (AQMP), which includes proposed control measures for stationary sources, and a control measure that proposes to establish a NOx emission limit for natural gas-fired commercial fan-type central furnaces with input rates greater than or equal to 175,000 Btu/h and less than or equal to 2,000,000 Btu/h. The NOx emissions of such furnaces are currently unregulated by SCAQMD. The measure seeks NOx emission reductions of 0.18 tons per day by 2023 and ultimately a reduction of at least 0.6 tons per day. This measure will be implemented in two phases, beginning with a technical assessment to be completed by 2014 and Phase II rule development by 2016.

AHRI submitted a response to SCAQMD on August 31, 2012. SCAQMD’s response  essentially indicates that its methodology for developing the commercial space heating emissions inventory is well established and has been used in previous AQMPs. They responded that their methodology incorporates EPA emission factors, local data on gas use by different sectors from local gas utilities, and information from the California Energy Commission, CARB, and local agencies. AQMD staff does not expect a delay in Rule 1111 implementation and believes that the current schedule in measure CMB-03 provides sufficient time for development of larger products based on residential furnace technology (multiple small burners) or single burner technologies used in other applications. Lastly, AQMD staff does not expect the compliance date for a rule based on control measure CMB-03 to be earlier than 2018. The District’s Governing Board is scheduled to discuss the AQMP on Friday, December 7. Once adopted by SCAQMD’s Governing Board, as well as state and federal environmental agencies, the document becomes the legally enforceable plan for meeting the federal 24-hour PM2.5 (fine particulate) standard by 2014. Contact: Aniruddh Roy.

Z21/83 Committee Meets
The Z21/83 Committee met on November 27 to consider proposed revisions to Z21 for unvented heaters.  The Committee adopted the proposed revisions, the consideration of which had been deferred from the Committee’s July 17 meeting. The Committee also appointed an ad hoc working group to develop comments on the two reports issued by the U.S Consumer Product Safety Commission (CPSC) regarding CPSC staff activities addressing carbon monoxide and gas-fired equipment.

Call for Comments on Proposed ASHRAE Standards and Addenda
The following public review drafts of ASHRAE standards and addenda are available for public review and comment here. Comments are due to ASHRAE by December 30.
Proposed Addenda to ASHRAE Standard 189.1-2011, Standard for the Design of High-Performance Buildings (Except Low-Rise Residential Buildings):
  • Addendum b - The purpose is to add some clarification to the requirements on flooring systems.
  • Addendum r - This addendum adds references to ANSI/ASHRAE Standard 170, Ventilation of Health Care Facilities.
  • Addendum z - Addendum z adds new requirements in Table C-16 Commercial Refrigeration Minimum Efficiency Requirements in Normative Appendix C - Prescriptive Equipment Efficiency Tables, of ASHRAE Standard 189.1.
  • Addendum u - The purpose of this addendum is to strengthen the standard’s storm water management requirements.
  • Addendum v - This addendum corrects the SI units used for Water Factor, limits the full-flush volume for all toilets to 1.28 gal per flush, limits kitchen faucet capacity to 1.8 gpm, and sets limits on the use of municipal reclaimed water for irrigation.
Revision of ASHRAE Standard 105-2007R, Standard Methods of Determining, Expressing and Comparing Buildings’ Energy Performance and Greenhouse Gas Emissions. This revision of ANSI/ASHRAE Standard 105 provides a method of energy performance determination, expression, and comparison that can be applied to any building. Some of the significant changes include changes in on-site energy storage over the annual calculation period and a significant revision to the Informative Annex J.

Proposed Addenda to ASHRAE Standard 90.1-2010, Energy Standard for Buildings Except Low-Rise Residential Buildings:
  • Addendum an - This modification allows the option to use energy rates either from actual local rates or EIA state data, where approved by the building official.
  • Addendum ar - This addendum corrects the definitions for walk-in coolers and walk-in freezers.
  • Addendum bs - This addendum reduces the occupancy threshold for demand-controlled ventilation from greater than 40 people per 1000 ft2 to equal to or greater than 25 people per 1000 ft2 with exemptions for certain occupancies.
  • Addendum ca - The proposed addendum requires that vestibule heating be locked out when outside air is above 45°F, the same temperature that lockout of freeze protection or ice melting systems is required in section
  • Addendum cb - This addendum removes the 10,000 cfm threshold for optimum start and adds a threshold for systems controlled by DDC. Language is added so it is clear that optimum start is only required for systems with setback control requirements.
  • Addendum cc - This addendum adds minimum efficiencies for both axial and centrifugal fan evaporative condensers with R-507A as the test fluid to Table 6.8.1G. Because of the numerous halocarbon refrigerants that can be utilized, a footnote has been added to the table that clarifies that evaporative condenser models intended for use with halocarbon refrigerants other than R-507A must meet the minimum efficiency requirements listed for R-507A as the test fluid.
  • Addendum cd - This addendum clarifies what to do with other piping system accessories that are not in series with the piping circuit, such as expansion tanks, fill lines, chemical feeders, and drains, which were not intended to be included because they do not have the same heat losses/gains and pressure drop.
  • Addendum ce - This addendum establishes package single zone systems as the baseline HVAC system type for all retail occupancies of two stories and less. Prior to this change, large retail facilities would have VAV reheat baseline systems which are not at all common in that building type.
  • Addendum cf - Since the publication of Addendum f, new data has become available that has enabled the establishment of a window-to-wall ratio for retail strip mall buildings, which is added in this addendum.
  • Addendum ck - This addendum requires the use of dual maximum control for VAV zone control when the building has DDC controls.
  • Addendum cl - This proposal updates the IEER values for air-cooled and water-cooled air conditioners and heat pumps above 65,000 Btu/h. Depending on the cooling capacity and product classes, the new IEERs are between 7 and 13 percent better than the values they are replacing. The new IEERs will become effective on January 1, 2016.
  • Addendum cn - This addendum allows laboratory designs that incorporate strategies to reduce peak airflows and minimum unoccupied airflows to document energy savings associated with reduced outside air volumes.
  • Addendum co - This addendum modifies the Lighting Power Densities in Table 9.5.1 to match the recommended light levels in the 10th Edition of the IES Lighting Handbook.
  • Addendum cp - This revision corrects a value in Table 5-5 for steel joist floors.
  • Addendum cr - This addendum modifies Table 9.6.1 to correct the required light levels for hospital corridors, assisted living dining spaces, and retail sales spaces. It also adds a new lighting power density for very small storage spaces, and modifies the living recreation room space type.
  • Addendum aq - This second public review of Addendum aq makes minor changes to address issues identified in sections and
  • Addendum ch - This addendum makes changes to the requirements for air and water cooled chillers as defined in section and the efficiency requirements listed in table 6.8.1C. This change is a continuation of the efficiency improvements that were implemented in 2010 by further improving the efficiency requirements.
