BAIHP researchers collaborate with a variety of entities in the homebuilding industry and the energy efficiency and research realm. Table 81 lists collaborators in the following categories:

• DOE National Labs (e.g. NREL, LBNL, ORNL)
• Code and Standards Bodies (e.g. RESNET, NFPA)
• Industry and Professional Organizations, Universities, and Suppliers

Northwest Energy Efficient Manufactured Housing Program (NEEM) Collaborations

ASHRAE: During 2003, in the capacity of chairing ASHRAE’s 6.2 Technical committee, BAIHP staff directed a major effort to revise Chapter 9 of the ASHRAE Systems Handbook, “Design of Small Forced-air Heating and Cooling Systems.” The revisions to the chapter, which incorporated BAIHP research, were accepted by the committee, and forwarded to ASHRAE for publication. In 2004 BAIHP staff provided assistance to other BA teams to improve chapter 43 of the ASHRAE Applications Handbook – Envelopes.

BAIHP staff have also participated in ASHRAE research projects, conferences, symposiums, seminars and forums, including:

• Authoring a paper on duct leakage, which was submitted and approved for presentation at ASHRAE summer meeting in 2004.
• Making a presentation at the ASHRAE summer meeting in 2003, “Uncontrolled Air Flow in Small Commercial Buildings.”
• Moderating a forum on HVAC experiences in HUD code housing at ASHRAE’s summer meeting in 2002. 20 industry and building science professionals participated in the forum.
• Co-chairing ASHRAE’s Technical Committee 6.3 – Residential Forced Air Heating and Cooling Equipment, which is responsible for ASHRAE standard 152 – Thermal Distribution Systems.
• Building America research on ductwork and HVAC systems will be included in the next version of the ASHRAE standards. Building America research will also be a part of future efforts in TC 6.3.
• NAHB Research Center: Throughout the BAIHP effort, WSU staff provided technical assistance and guidance to the NAHB Research Center Energy Value Housing Awards, judging submittals, providing de-briefing to builders, and participating on workshops.  NEEM builders Fleetwood, Champion, Valley and Marlette have received EVHAs for factory built housing.

NFPA-501: BAIHP continues to support the NFPA standards process. The NFPA standard is typically incorporated into the HUD code, which governs the construction of over 250,000 HUD code homes each year.

• In 2003, BAIHP staff integrated BAIHP duct leakage and cost data into proposals to the NFPA-501 committee. Based on this data, NFPA approved a new standard on duct tightness, as well as a refined duct testing protocol.
• In 2002, BAIHP staff cited Building America research and demonstration efforts in support of additional successful proposals for standards revision, including duct testing, and use of mastic in duct sealing.

ACEEE

• BAIHP staff have co-authored two papers presented at ACEEE Conferences, “Pushing the Envelope: A Case Study of Building the First Manufactured Home Using Structural Insulated Panels,” and “Washington State Residential Ventilation and Indoor Air Quality Code (VIAQ) - Whole House Ventilation Systems Field Research Report.”
• In 2004, BAIHP staff coordinated 24 peer reviewed papers for the Residential technologies track at the Summer Study and coordinated informal sessions on HUD-code housing.

National Institute of Standards and Technologies (NIST): BAIHP staff continues to work with NIST staff and industry representatives to evaluate ventilation and IAQ issues in HUD code homes.

• BAIHP staff also worked with NIST and the Energy Conservancy to perform tests on a typical HUD code model house on the NIST campus in Gaithersburg, Maryland. Testing indicates low flow rates of the whole house ventilation system and significant duct leakage.
• In 2004, discussions with NIST, LBL, Ecotope and Energy Conservatory continued on a retrofit research effort with Dupont Tyvek, and development of new ventilation system controls with Panasonic. These discussions will continue.

National Manufactured Housing Research Alliance (MHRA): BAIHP staff continues to participate on MHRA’s ENERGY STAR committee, which is developing Quality Assurance procedures with USEPA on ENERGY STAR manufactured homes. An article on the ZEMH appeared in the MHRA newsletter. WSU worked with MHRA to provide an article on the ZEMH project. WSU continues to provide technical support to MHRA on ENERGY STAR and other building science/energy related efforts such as the MHI roadmap.
