The following proposed innovation in design credit is intended to demonstrate that Corrugated Stainless Steel Tubing (CSST) designed for distribution of natural gas and LPG (propane Gas) systems saves time, reduces cost, and is environmentally friendly where integrated in a holistic approach to a building project. This innovative technology is the only standard based natural gas and LPG (propane gas) system manufactured, designed sized and installed under the ANSI LC1 certification process. CSST is IAPMO, ICC and CSA listed; IFGC, UPC and NFPA-54 approved as a gas-piping material. This system is installed with fewer fittings eliminating leak paths in the natural gas or LPG (propane gas) system, thus making the system safer within a structure. The inherent flexibility and light weight will reduce costs and help prevent job related accidents. Most manufactures\' of CSST incorporate a fitting which uses a metal to metal seal with no gaskets or O-rings and features which allows for maintaining of the integrity of the Polyethylene jacket protecting the system from corrosion and harsh environments. The Polyethylene jacket, as required by ANSI LC1, is constructed to meet the ASTM E84 requirement for Fire /Smoke (25/50) making the system safer in the event of fire. This innovative technology eliminates the need for welding of natural gas and LPG piping and the dangers associated with such procedures, such as toxic fumes from welding gases, flux and brazing rods and smoke and soot caused by welding. This technology reduces respiratory problems associated with inhaling the toxic fumes resulting from welding of natural gas and LPG piping and eliminates the dangers of fire associated with welding of natural gas and LPG piping. It also eliminates personal injury associated with the use of welding and threading equipment. It is our intent to submit for this credit as a system which exceeds the LEED-NC performance as related to a safer environment during construction and safer system within a structure, for the life of the structure.
