25、ign: Petroleum Fuel Facilities, including its referenced standards (American Petroleum Institute (API), American National Standards Institute (ANSI), NFPA, UL, FM, etc.), the current issue of UFC 3-460-01 and its referenced standards take precedence. 1-9 GENERAL POLICY. Design plumbing systems to pr
26、ovide economy and reliability. Provide simple, functional designs. 1-9.1 5 7Energy Efficiency and Water Conservation. Plumbing system energy usage and equipment efficiencies shall comply with UFC 3-400-01, Energy Conservation, requirements. Per Executive Order 13423, employ strategies that in aggreg
27、ate use a minimum of 20% less potable water than the indoor water use baseline calculated for the building after meeting the Energy Policy Act of 1992, Uniform Plumbing Code 2006, and the International Plumbing Code 2006 fixture performance requirements. /7/ /5/ 1-9.2 Reliability. Where interruption
28、 of a service cannot be tolerated or where failure of a system would drastically reduce the efficiency of a facility, provide dual-fuel capability and/or redundant system components. 1-9.3 Piping Arrangement. Conceal piping in permanent-type structures. In limited life structures, piping may be inst
29、alled exposed, except when specific project criteria justify concealment or where concealment does not increase the cost of the project. Exposed piping attached to or near fixtures or equipment, or subject to high heat or frequent washing, must be copper, brass, or chromium plate. Prime other expose
30、d piping with paint suitable for metal surfaces and finish-paint with color to match background. Arrange piping runs to minimize interference with personnel and equipment. For critical piping services such as medical gas systems, route piping so that it is not on exterior walls or walls shared with
