WSR 13-15-160
PROPOSED RULES
[Filed July 23, 2013, 4:40 p.m.]
Original Notice.
Preproposal statement of inquiry was filed as WSR 13-07-078.
Title of Rule and Other Identifying Information: Amendments to chapters 51-11C and 51-11R WAC, the Washington State Energy Code, commercial and residential provisions.
Hearing Location(s): Center Place Event Center, 2426 North Discovery Place, Spokane Valley, WA 99216, on September 20, 2013, at 10 a.m.; and at the DES Presentation Room, 1500 Jefferson S.E., Olympia, WA 98504, on October 18, 2013, at 10 a.m.
Date of Intended Adoption: November 8, 2013.
Submit Written Comments to: Ray Allshouse, P.O. Box 41449, Olympia, WA 98504-1449, e-mail sbcc@ga,wa,gov [sbcc@ga.wa.gov], fax (360) 586-9088, by October 25, 2013.
Assistance for Persons with Disabilities: Contact Peggy Bryden by September 9, 2013, (360) 407-9280.
Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: Makes editorial changes to the following sections of the residential energy portion of the Washington State Energy Code:
Section C301.1/R301.1 is amended to move Ferry, Okanogan, Pend Oreille, and Stevens counties from Climate Zone 6B to Climate Zone 5B. This would allow those four counties to share training and other resources with Spokane County, as previously done under the 2009 code. This is coordinating with the emergency rule filed as WSR 13-14-069.
Section C402.3.1 and Tables C402-1 through C402-4 are amended to create a prescriptive path method to increase the wall glazing area above base code levels without going through the Total Building Performance method. This would allow a continuation of current building practices modified slightly to achieve more energy savings than under the 2009 code while still remaining economically viable. This is coordinating with the emergency rule filed as WSR 13-14-070.
Table C402.2 is modified to correct language in footnote c to coordinate with the language in Table C402.1.
Section C408.3 is amended to provide an exception to commissioning for smaller, simpler lighting systems. This was intended to be included in the original rule adopted in November but was erroneously left out.
Rule is not necessitated by federal law, federal or state court decision.
Name of Proponent: State building code council, governmental.
Name of Agency Personnel Responsible for Drafting and Implementation: Krista Braaksma, P.O. Box 41011, Olympia, WA 98504-1449, (360) 407-9278; and Enforcement: Local jurisdictions.
No small business economic impact statement has been prepared under chapter 19.85 RCW. The substantive portions of the proposed rule were written in response to petitions to provide economic relief to two sectors of the building industry. The first is reclassifying Climate Zone 6B as Climate Zone 5B; the second to allow a prescriptive path to increase the percentage of glazing allowed in above grade walls. The remainder of the rule provides minor corrections to provisions to clarify intent and have no cost impact or further reduce the cost of compliance. Because the proposed rules mitigate the effect of the 2012 Energy Code and reduce costs rather than imposing new requirements, there is no negative economic impact on small businesses in the state.
A cost-benefit analysis is not required under RCW 34.05.328. The state building code council is not a listed agency under RCW
34.05.328 (5)(a)(i). This rule is not considered to be substantive; its function is to provide economic relief in certain instances and make some noneditorial corrections to the text.

1. Confirm that the placement, sensitivity and time-out adjustments for occupant sensors yield acceptable performance.
2. Confirm that the time switches and programmable schedule controls are programmed to turn the lights off.
3. Confirm that the placement and sensitivity adjustments for photosensor controls reduce electric light based on the amount of usable daylight in the space as specified.
