30、 0757650 0539245 802 m Industry Roundup - Trade Associations to Discuss Merger Discussion is expected to start this spring on a merger of the Northamerican (sic) Heat- ing, Refrigerating and Airconditioning (sic) Wholesalers Association (NHRAW) and the Air-conditioning and Refrigeration Wholesalers
31、(ARW). The merger would create an association of about 580 wholesale distribution companies, 200 manufacturers . and 100-plus affiliated representatives and associations. David Kellough, ARW executive direc- tor, said the issue initially came up when the executive committees of both associations met
32、 last spring and summer to discuss a possible joint convention. The committees decided that a unified convention would not be feasible until 1998, at the earliest. They also decided it would make sense to also discuss a merger as talks continued on the joint convention. Resolutions authorizing the m
33、erger discussions were approved by the memberships of the ARW in October and Kellough and Jim Wilder, executive vice president of NHRAW, both said the merger would create a unified voice and bet- ter position the wholesale industry to deal with challenges such as asset management, inventory control
34、and alternative channels of distribution. “It just makes sense for one organization to represent the wholesale side of the HVAC other states have shifted energy programs to functions in other departmental agencies. Building Codes One of the most effective ways, how- ever, to assure a minimum level o
35、f energy efficiency in buildings is to adopt and enforce energy standards. In general, building codes and standards are developed on the national level, and administered and enforced at the local level. Most commercial building energy codes are based at least in part on standards developed jointly b
36、y ASHRAE and the Illuminating Engineer- ing Society (IES). Despite state-level cutbacks in energy offices, there are many activities underway to promote energy efficiency and energy conservation measures-some educational, some voluntary and some regulatory. The Building Codes Assistance Project (BCA
37、P) is in its second year, and was established to promote and accelerate the adoption, imple- mentation and utilization of energy- efficient construction standards in the U.S. It is a joint initiative of the Alliance to Save Energy, The American Council for an Energy-Efficient Economy and the Natural
38、 Resources Defense Council. BCAP receives funding from the U.S. Department of Energy (DOE) and the Energy Foundation. BCAP tracks energy activities in the states, and produces a periodic state-by-state update on the status of state-wide energy building codes for both residential and com- mercial str
39、uctures. The Energy Policy Act of 1992 (EPACT) required all states to review their building energy codes, and certify to the Secretary of Energy by Oct. 24, 1994, that they meet the provisions of EPACT. For commercial buildings, EPACT specifies that ASHRAE Journal February 19% new commercial constru
40、ction must meet or exceed, by that date, ASHRAE/IES Stan- dard 90.1-89. By October 1996, states must demonstrate that their revised code provi- sions meet or exceed the requirements of ASHRAEDES 90.1-1989 for commercial and high-rise residential buildings. EPACT, however, does not require states to

BCAP works with private-sector and governmental organizations as part of its efforts to
43、 advocate the adoption of man- datory state and local energy codes and standards. The experience gained by the project has shown the reluctance in a par- ticular locale to move from a condition of no energy requirements directly into a climate of mandatory state-wide regulations or codes. In situati
44、ons where no energy requirements have been in effect or have not been enforced, voluntary energy-efficiency programs-coupled with public education and training of stakeholders (builders, code officials, etc.)-have proven to yield positive results and serve as interim steps toward future mandatory pr
45、ograms. Some volun- tary programs feature home energy rating systems (HERS) or similar programs for cmmercial buildings. The trend is not always toward improv- ing energy efficiency. State-level legislative initiatives have been introduced to roll back energy-efficiency requirements already in place
46、, in favor of less-stringent energy con- servation requirements (such as those reflected in earlier verisons of ASHRAEs energy-efficiency standards). However, progress is being made. The impact of federal law PL 102-487 (EPACT) will pressure states to demonstrate com- pliance with energy-efficiency
47、requirements. Some states are moving from energy provi- sions adopted by local governments to state- wide codes. One large eastern state with some 2,600 local code jurisdictions is adop- ting a single state-wide code. BOCA Code Updated The Building Officials and Code Administrators (BOCA) has overwh
48、elm- ingly adopted the 1995 verison of the MEC as the energy conservation provisions for the 1996 National Building and Mechanical Codes. There is no longer a national mechanical code, per se. The BOCA update is 1995 MEC, Chapter 13 of the National Building Code. Other codes that relate to energy ha
49、ve been deleted and everything is tied back to Chapter 13 adoption by reference of the 95 MEC. One of three major model code groups in the US., the BOCA codes are adopted and utilized in 19 states, primarily in the Midwest, Mid-Atlantic and Northeast regions. The 1996 edition of the BOCA codes will be available in early 1996. The BCAP effort played a significant role in the updating of the energy provisions of the BOCA code. The BCAP program is directed by a seven-person Steering Committee including representatives of the organ
