40、RN 40-2 PSNC-ENGL 1975 0757b50 0532815 T2b Streamlining the Building Regulatory Process By Charles R. Mir, and J. Cox, Ph.D., RE. ASHRAE Associate Direcfor ASHRAE Director of of Government Affairs Government Affairs he nation has a myriad of building codes and standards designed to ensure the public
41、s health and safety. With a political history that encourages delegation of authority to those levels of government closest to the people, the U.S. system of building codes includes various layers of government. The federal government, several territories, 50 states and local jurisdictions (whether
42、city, county or regional) adopt and enforce an array of complex (and often competing) rules, regulations, processes and procedures related to the built environment. In the U.S., there are over 44,000 governmental jurisdictions, almost all of which adopt some form of five major sets of construction c
43、odes and over 2000 technical standards. The result in many sit- uations is an expensive and confusing system for all affected par- ties (the construction community, governments, financial and enhance compliance with model codes and standards. Positive results could reduce time delays and constructio

Governments may also be in a better position to resolve competing public inter- ests and purposes. Goals It is envisioned that t
45、he goals of the project would include the development of a package of model reforms and imple- mentation strategy. If adopted by federal, state, regional or local governments, the processing time would be shortened and would more efficiently move construction projects from the initial zoning approva

During the first three years of its work (and perhaps while the work of the committee is still underway), a goal is that at least one governmental jurisdiction in each state will adopt one - insurance institutions and the or more of the programs sug- consumers). ge
