WalterMichael W. WoodfordCraig P. WrayWayne R. Reedy, BOD ExOThomas E. Watson, COStephanie Reiniche, Manager of StandardsSPECIAL NOTEThis American National Standard (ANS) is a national voluntary consensus standard developed under the auspices of the AmericanSociety of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Consensus is defined by the American National StandardsInstitute (ANSI), of which ASHRAE is a member and which has approved this standard as an ANS, as “substantial agreement reached bydirectly and materially affected interest categories. This signifies the concurrence of more than a simple majority, but not necessarily unanimity.Consensus requires that all views and objections be considered, and that an effort be made toward their resolution.” Compliance with thisstandard is voluntary until and unless a legal jurisdiction makes compliance mandatory through legislation.ASHRAE obtains consensus through participation of its national and international members, associated societies, and public review.ASHRAE Standards are prepared by a Project Committee appointed specifically for the purpose of writing the Standard. The ProjectCommittee Chair and Vice-Chair must be members of ASHRAE; while other committee members may or may not be ASHRAE members, allmust be technically qualified in the subject area of the Standard. Every effort is made to balance the concerned interests on all ProjectCommittees.The Manager of Standards of ASHRAE should be contacted for:a. interpretation of the contents of this Standard,b. participation in the next review of the Standard,c. offering constructive criticism for improving the Standard, ord. permission to reprint portions of the Standard.DISCLAIMERASHRAE uses its best efforts to promulgate Standards and Guidelines for the benefit of the public in light of available information andaccepted industry practices. However, ASHRAE does not guarantee, certify, or assure the safety or performance of any products, components,or systems tested, installed, or operated in accordance with ASHRAE’s Standards or Guidelines or that any tests conducted under itsStandards or Guidelines will be nonhazardous or free from risk.ASHRAE INDUSTRIAL ADVERTISING POLICY ON STANDARDSASHRAE Standards and Guidelines are established to assist industry and the public by offering a uniform method of testing for ratingpurposes, by suggesting safe practices in designing and installing equipment, by providing proper definitions of this equipment, and by providingother information that may serve to guide the industry. The creation of ASHRAE Standards and Guidelines is determined by the need for them,and conformance to them is completely voluntary.In referring to this Standard or Guideline and in marking of equipment and in advertising, no claim shall be made, either stated or implied,that the product has been approved by ASHRAE.

It is merelyinformative and does not contain requirements necessaryfor conformance to the standard. It has not beenprocessed according to the ANSI requirements for astandard and may contain material that has not beensubject to public review or a consensus process.Unresolved objectors on informative material are notoffered the right to appeal at ASHRAE or ANSI.)FOREWORDThe requirements for pipe insulation contained in theASHRAE 90.1-2007 standard are unchanged from the 90.11999 version of the standard. The 1999 requirements weredeveloped, in large part, based on the work of the PacificNorthwest National Laboratories (Somasundaram and Winiarski) in 1995. Since that time, significant changes in theinstalled costs of pipe insulation have occurred. Also, the 90.1SPPC has adopted new economic criteria to be used in developing standard requirements. The proposed changes incorporate these updated criteria and cost data.The approach used in developing these proposed requirements parallels the PNNL work with the exception that therequirements have been expanded to include higher usage systems. Requirements are presented for low use ( 4,400 hrs/yr)and high use (? 4,400 hrs/yr) systems. In addition, footnoteshave been added to address constrained locations and to clarify the requirements for direct-buried piping.Note: In this addendum, changes to the current standardare indicated in the text by underlining (for additions) andstrikethrough (for deletions) unless the instructions specifiTABLE 6.8.3Addendum bi to 90.1-2007Revise the Standard as follows (I-P):6.4.4.1.3 Piping Insulation.
