ERRATA SHEET FOR THE FIRST PRINTING OF ANSI/ASHRAE/IESNA STANDARD 90.1-2004 (SI edition) Energy Standard for Buildings Except Low-Rise Residential Buildings September 22, 2008 The corrections listed in this errata sheet apply to the first printing of ANSI/ASHRAE/IESNA Standard 90.1-2004, SI edition, identified as “86248 PC 1/05”on the outside back cover of the standard. Shaded item has been added since the previously published errata sheet dated May 29, 2007 was distributed. More than one errata sheet may be required for a specific document. Please review the entire list on the ASHRAE website related to the applicable document and download all that apply. NOTICE: ASHRAE now has a list server for Standing Standards Project Committee 90.1 (SSPC 90.1). Interested parties can now subscribe and unsubscribe to the list server and be automatically notified via e-mail when activities and information related to the Standard and the Users Manual is available.

Page(s) Erratum 6 Section 3.2 Definitions. Change (a) and (b) in the definition for degree-day to read as follows: (Note: Additions are shown in underline and deletions are shown in strikethrough.) degree-day: the difference in temperature between the outdoor mean temperature over a 24-hour period and a given base temperature. For the purposes of determining building envelope requirements, the classifications are defined as follows: (a) cooling degree-day base 10°C, CDD10: for any one day, when the mean temperature is more than 10°C, there are as many degree-days as degrees CelsiusFahrenheit temperature difference between the mean temperature for the day and 10°C. Annual cooling degree-days (CDDs) are the sum of the degree- days over a calendar year. (b) heating degree-day base 18°C, HDD18: for any one day, when the mean temperature is less than 18°C, there are as many degree-days as degrees CelsiusFahrenheit temperature difference between the mean temperature for the day and 18°C. Annual heating degree-days (HDDs) are the sum of the degree- days over a calendar year. 15 Section 3.3 Abbreviations and Acronyms. Change CTI from “Cooling Tower Institute” to “Cooling Technology Institute”. 17 Section 5. Building Envelope. In the compliance path figure at the beginning of Section 5 correct the spelling of prescriptive so it reads “5.5 Prescriptive Path”. 19 Table 5.5.3.1. Change the title of Table 5.5.3.1 as follows: (Note: Additions are shown in underline and deletions are shown in strikethrough.) Page 2 of 7 ©2008 ASHRAE. All rights reserved. Roof U-Factor Multipliers for Exception to 5.5.1.1 5.5.3.1 22 through 30 TABLES 5.5-1 through 5.5-8 Building Envelope Requirements. Add a footnote to the bottom of Tables 5.5-1 through 5.5-8 as follows: “The following definitions apply: ci = continuous insulation (see Section 3.2), NR = no (insulation) requirement.” 24 TABLE 5.5-3 Building Envelope Requirements for Climate Zone 3 (A, B, C). In footnote “b” of Table 5.5-3 change “non-residential” to “nonresidential”. 34 P.O. Box 73383, Houston, TX 77273-3383 92 A3.3.1 General. (Steel-Framed Walls) In the fourth sentence of Section A3.3.1 change “Table A-21” to “Table A9.2B”. 118 Table B-3 International Climate Zones. Inadvertent omission of the climate zones for New Zealand. Insert the following climate zone numbers as published in Addendum “am” to 90.1-2001: Country Page 4 of 7 ©2008 ASHRAE. All rights reserved. City (Providence or Region) Zone New Zealand Auckland Airport 4 Christchurch 4 Wellington 4 130 Normative Appendix D Climatic Data. At the top of the page delete the second sentence that reads “Table numbers corresponding to the envelope criteria tables in Normative Appendix B are also included.” 153 Table D-2 Canadian Climatic Data. The SI edition of Standard 90.1 incorrectly included I-P climatic data in Table D-2. See Table D-2 for changes (attached). Table changed to reflect SI units. (Note: Additions are shown in underline and deletions are shown in strikethrough.) 168 Table F-2 Addenda to ANSI/ASHRAE/IESNA Standard 90.1-2001, Approval Dates. In the third and fourth columns for Addenda q, t, u, y, z, aa, ab, ac, ae, ag, ah, ai, al, and am change the July 1, 2001 date to July 1, 2004 (14 places in each of the two columns). -,-,- Page 5 of 7 ©2008 ASHRAE.
