Changes to Fan Efficiency Requirements Proposed for ASHRAE, IES Energy Standard

ATLANTA – A proposed change to ASHRAE and IES’s energy standard currently open for public input would encourage advancement of efficient fan design.

Proposed addendum u to ASNI/ASHRAE/IES Standard 90.1-2010, Energy Standard for Buildings Except Low-Rise Residential Buildings, would add a reference to the Air Movement and Control Association (AMCA) International’s Standard 205-10, Energy Efficiency Classification for Fans. This would require fan efficiency requirements to be classified based on fan efficiency grades.

“Currently, the standard only regulates fan power at the system design level,” Ned Heminger, chair of the Standard 90.1’s Mechanical Subcommittee, said. “In other words, the amount of fan power allowed in a system is based on the system maximum airflow rate. However, the standard does not set requirements for the manufacturers of fans. As a result, there is a wide range of fan efficiencies available on the market. When the current prescriptive requirements were set for fan power, the fan efficiency chosen was achievable by most fans currently available at the time. Developing a fan efficiency metric that applies to the manufacturing of fans will encourage the advancement of efficient fan design. As fan efficiency increases, fan power needs decrease. This allows the standard to improve on the fan power limits in the future. The proposed addendum has set the initial efficiency bar at a level that is achieved by most fans, with assistance from ASHRAE technical committee 5.1, Fan Design and Application. The intention is to work with TC 5.1 to increase the efficiency requirements for fans in future versions of the standard.”

He also noted that the proposed addendum was issued utilizing ASHRAE’s advisory public review option available to solicit feedback from the industry. This was done at the recommendation of committee members to better understand the impact to the industry as the standard is proposing compliance with a new certification standard. The committee recognizes the importance of constructive feedback from the industry and looks forward to hearing their suggestions. Unlike comments received through ASHRAE’s formal call for public comments process, comments received on advisory public reviews are considered opportunities for constructive input from interested and materially affected parties into the development of proposed language that will be issued for official public review and need not be resolved or formally acted on by the project committee.

Addendum u is open for advisory public review until July 10, 2011, along with five other proposed addenda open for public review. Nine proposed addenda to the standard are open for public review until July 25, 2011. For more information, visit www.ashrae.org/publicreviews.

Other addenda out for review until July 10, 2011 are:
• Addendum l fixes a mistake in Section for fan brake horsepower methodology.
• Addendum n clarifies that the total lumens/Watt for the entire elevator cab is being required to meet the efficiency requirement, but that it is not required that each individual light source must comply.
• Addendum o updates the fenestration air leakage provisions to clarify the requirements for glazed sectional garage doors. A new definition for sectional garage doors is also added.
• Addendum s – Large amounts of fan energy can be wasted when zones report incorrect information to the control system, which causes the supply fan speed to increase, often to maximum speed. This addendum requires additional safeguards to prevent this, and for non-DDC systems requires location of sensors in locations that do not require high setpoints.
• Addendum t corrects the reference to the proper section for damper leakage in (Dampers). This addendum also clarifies that the damper leakage requirements in (Damper Leakage) and as defined in Table (Maximum damper leakage) applies to the return air dampers used in economizers.
Addenda out for public review until July 25, 2011 are:
• Addendum a updates the test procedure references for product information in the Tables in Section 10.8 (product information), and also adds a normative reference in Chapter 12. This will make the table references more consistent with other equipment tables (and other test procedure references).
• Addendum cj modifies Appendix G (Performance Rating Method) to change the requirements for economizers and how they are modeled in computer rooms.
• Addendum m adds power density and control requirements to capture additional savings; adds a needed exemption for practical application, includes submittal requirements; and changes control credits to apply only to lamps in multi-lamp fixtures that are controlled.
• Addendum q updates the ASHRAE dynamic glazing definition to match the National Fenestration Rating Council dynamic glazing definition.
• Addendum r clarifies the intent of the committee and relocates all wording related to thermostat and humidity schedules to the Schedules section of Table G3.1 for greater ease of use.
• Addendum v requires that the controlled receptacles be appropriately identified so that users can clearly distinguish between controlled and non-controlled receptacles.
• Addendum w clarifies the credits for renewable energy and purchased energy in Section 11 (Energy Cost Budget Method) and Appendix G (Performance Rating Method).

Letter from Lynn Bellenger, ASHRAE President

Dear ASHRAE Members:

Today building owners and occupants are demanding that their buildings provide better performance than has been delivered in the past. Government and private owners have mandated that new buildings and building retrofits be designed, constructed, tested, commissioned and operated to a high performance standard. To date, the industry has not been able to consistently deliver on this mandate. This situation creates a unique opportunity for our organization to provide a solution that will successfully deliver on this high performance building mandate.

Over the last two years, ASHRAE has worked to address the needs of the industry and deliver high performance buildings; simultaneously, the National Environmental Balancing Bureau (NEBB – www.nebb.org) was conducting the same investigation for delivering high performance buildings. In 2010, ASHRAE and NEBB began discussions to determine if collaboration between the two associations could provide a solution to delivering high performance buildings by influencing the design, construction, testing, commissioning and operations of buildings to a high performance standard as a normal building delivery process.

Through these discussions, the NEBB Board of Directors and the ASHRAE Board of Directors have determined the following:
• NEBB is a premier international certification association for firms that deliver high performance building systems. NEBB brings unique strengths to the building performance discipline.ASHRAE is a world leader in the arts and science of heating, ventilating, air conditioning and refrigeration and promotes high performance buildings through standards, guidelines, design manuals, and educational courses. ASHRAE brings unique strengths to the building performance discipline.
• ASHRAE and NEBB believe that building performance is evolving as a new standard by which our industry will be measured in the future.
• ASHRAE and NEBB believe that combining their strengths would produce an approach to building performance that would be far superior to any that could be produced by their individual efforts.

Our discussions have centered upon consolidating the organizations in a way that creates a separate organization under the ASHRAE umbrella that concentrates upon performance of the built environment and the associated education, training and certifications for building performance professionals. This organization would encompass all activities that provide the end performance desired by the industry, including design, construction, testing, commissioning, operation and ongoing performance verification. The organization could also align with other industry groups that have similar goals, and ultimately create a significantly enhanced resource for those that seek to deliver high performance buildings.

Accordingly, on May 10, 2011, President Bill Neudorfer of NEBB and I formed negotiating teams to determine if a consensus can be achieved on consolidating the two organizations. The opportunities that exist for the consolidated organization are immense. At the same time, much needs to be done to ensure that any consolidation would optimize the strengths of the two organizations. We value your input on the process and assure you that the negotiation process will be fair, thorough and transparent.

As talks continue between the two organizations, it is expected that more information will be available on ASHRAE.org outlining any consolidation proposals. As an ASHRAE member, you are encouraged to send your comments and questions to ashrae.nebb@ashrae.org (or simply reply to this email). President Neudorfer is also reaching out to the NEBB membership to seek their thoughts through a letter similar to this one.

Personal regards,

Lynn G. Bellenger
2010-11 ASHRAE President
