INTERPRETATION IC 90.1-2004-1 OF ANSI/ASHRAE/IESNA STANDARD 90.1-2004 Energy Standard for Buildings Except Low-Rise Residential Buildings Date Approved June 25, 2005 Request from: Roger Chang (E-mail: ), Associate Member, 155 Avenue of the Americas, New
2、York, NY 10013. Reference: This request for interpretation refers to the requirements presented in ANSI/ASHRAE/IESNA Standard 90.1-2004, Section 5.2.1 Compliance, relating to gross wall area. Background: Standard 90.1-2004 does not appear to be clear as to what gross wall area means. International E
3、nergy Conservation Code is clear that prescriptive requirements are based on window to above-grade wall area. This impacts all sections of the code where the window-to- wall area ratio is taken into consideration. Interpretation: Gross wall area refers to above-grade wall only. Question: Is this int
4、erpretation correct? Answer: No. Comments: Section 3.2 defines “building envelope” to include “the elements of a buildingthat enclose.spaces through which thermal energy may be transferred to or from the exterior”. Section 3.2, in the definition of “wall” states “this includes above- and below-grade
5、 walls, between floor spandrels, peripheral edges of floors, and foundation walls”. Section 3.2 defines “gross wall area” as “the area of the wall measured on the exterior face from the top of the floor to the bottom of the roof”. Therefore, for buildings with conditioned space below-grade, the gros
6、s wall area extends from the top of the surface of the floor of the lowest conditioned space to the bottom of the roof of the highest conditioned space. (Note that the use of a similar term in a document from another organization is irrelevant to an interpretation of Standard 90.1.) Page 1 of 2 2006

The budget building design is a representation o
9、f a building that meets the prescriptive path ASHRAE Standard 90.1. The prescriptive path does not specify minimum outdoor air requirements. The minimum outdoor air for the budget building and the proposed building design must be the same. Page 1 of 9 INTERPRETATION IC 90.1-2004-5 OF ANSI/ASHRAE/IES
10、NA STANDARD 90.1-2004 Energy Standard for Buildings Except Low-Rise Residential Buildings Date Approved January 23, 2006 Request from: Richard Lord (E-mail: ), United Technologies, Carrier, One Carrier Place, Farmington CT, 06034. Reference: This request for interpretation refers to the requirements
11、 presented in ANSI/ASHRAE/IESNA Standard 90.1-2004, Table 6.8.1A and Table 6.8.1B requiring a 12.0 SEER and 7.4 HSPF for less than 65,000 Btu/h cooling capacity machines. Background: As per note “c” these are for 3 phase products with a cooling capacity less than 65,000 Btu/h. Single phase products
12、are covered by the NAECA federal standard. The 12.0 SEER and 7.4 HSPF levels in Table 6.8.1A and Table 6.8.1B were implemented when the NAECA levels where to be set at the 12.0 SEER and 7.4 HSPF. Since that time the federal levels have been further increased to 13.0 SEER and 7.7 HSPF. Because of NAE
13、CA change to 13 SEER a new ASHRAE 90.1 change proposal (CM 90.1-05-12-0002/001) was submitted by Karim Amrane. This change proposal has been approved by the Mechanical Subcommittee and the ASHRAE SSPC 90.1 and was approved by the ASHRAE Standards Committee on 1/21/2006. The final change is referred
14、to as Addendum f to ANSI/ASHRAE/IESNA Standard 90.1-2004. The effective date shown in Addendum f is 1/23/2006. There is considerable confusion in the industry about the various effective dates for the single and 3 phase 13 SEER requirement and this request is being submitted to request clarification
15、 of the implantation dates for 13 SEER. Interpretation: It is my understanding that the following is the correct interpretation of the requirements and effective date. Single Phase Products For single phase products with a capacity less than 65,000 Btu/h the requirements are defined by the NAECA sta

19、Cooled, Single Package (heating) - 7.7 HSPF The ASHRAE 90.1-2004 effective date as defined by Addendum f is 1/23/2006 but this does not mean the federal effective date will be 1/23/2006. For the ASHRAE 90.1 requirements to be implemented as the federal minimum efficiency for 3 phase products Addendu
20、m f must be approved by the Department of Energy (DOE) as defined in the Energy Policy Act of 1992 (see attachment). If DOE approves the ASHRAE levels then the requirements would become the federal minimum 2 years after the 1/23/2006 effective date in the ASHRAE standard. In this case the federal da
21、te would then be 1/23/2008. Also defined by the Energy Policy Act of 1992, once ASHRAE has approved the new levels a state has the option to require the new levels for new construction, but not on replacement equipment, during the period between the ASHRAE effective date of 1/23/2006 and the anticip
