34、Director of Associate Government Government Affairs Affairs Director forum addressing the impact of A government budget changes and restructuring on engineering was held at the National Academy of Sciences in Washington, D.C. Initiatives in Congress to balance the federal budget, along with pro- pos
35、als for reorganization of government agencies will have a direct impact on federal science, engineering and technology pro- grams and policies. Officialsfrom both the Executive Branch and the U.S. Congress discussed the events this year from the perspectives of the Democratic and Republican politica

Two members of Congress keynoted the days events followed by updates from Congressional staff explaining the Republican perspective and the Demo- cratic perspective on the budgetary pro- cess underway. The Presidents perspec- tive was presented by various department and agency officials.
37、The days events were organized by the American Society of Mechanical Engi- neers (ASME) to provide up-to-date brief- ings for their members who participate as volunteers in the policy areas of education, R it will not return to an agrarian economy. We need to provide a climate whereby private-sector
38、 research will increase from the current 1% level up to 3%,” Rep. Brown said. According to Rep. Brown, the U.S. faces some difficult policy questions: What should the federal role be in the nations R&D? What is the private sector role? In the future the federal government must leverage its R&D fundi
39、ng to a greater extent. The scientific and engineering com- munities were urged by the Congressman to become even more involved in the policy arena in education as well as research. Brown pointed out one troublesome area when he characterized the U.S. as having the best system in the world of gradua
40、te education in the sciences and engineering, and at the same time having the worst system of secondary education of any industrialized nation in the same technical areas. There have been areas of failed federal policies over a period of 20 to30 years. The talents are needed of those individuals who
41、 can take the long-term viewpoint and not be transfixed on short-term funding levels in a single discipline. New priorities must be established and emphasized. As he has for some time, Rep. Brown encouraged the scientific and engineering communities to be even more involved in a timely manner. ASHRA

These differences-when combined with recent improvements in systems technology and the publi2s expectations of ever-greater comfort-have led to sweeping transformations i

And how does the consulting engineer meet these new needs and HVAC requirements in a practical, cost-effective manner? To answer these questions, this article will explain how the uses and des

Then, it will explain HVAC requirements and design solutions in a wide range of different occupancies. Arenas: Yesterday and Today A generation
48、ago, the typical arena was a single-purpose building where spectators went to a sports event, watched the basket- bail or hockey game, and then left for home immediately afterward. Food service usually was limited to hot dogs, popcorn, and beverages. The building included only a handful of significa
49、nt occupancies or space types, including the event floor, spectator seating, and team locker rooms. Building systems were also rudimentary. Many older arenas were poorly heated and ventilated, and usualiy lacked air condition- ing. They were cold and drafty in winter, hot and humid in summer. But most spectators didnt mind. At a time when automobile air conditioning was still a noelty, the public accepted this discom- fort as part of the game-going experience. The outcome of the games, not the comfort level of the arena, was all
