EXPEDITED RULES
BUILDING CODE COUNCIL
[Filed November 17, 2020, 3:15 p.m.]
Title of Rule and Other Identifying Information: Chapter 51-11C WAC, 2018 Washington state energy code, commercial.
Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: This filing corrects errors in the minimum efficiency tables.
Reasons Supporting Proposal: It was brought to our attention that Table C403.3.2(3), filed with the adoption of the 2018 Energy Code under WSR 19-24-040, contains some errors where the efficiency does not match that in ASHRAE 90.1 as was intended.
Statutory Authority for Adoption: RCW 19.27A.025, 19.27A.045.
Statute Being Implemented: Chapter 19.27A RCW.
Rule is necessary because of federal law, [no information supplied].
Name of Proponent: [No information supplied], governmental.
Name of Agency Personnel Responsible for Drafting and Implementation: Krista Braaksma, 1500 Jefferson Street S.E., Olympia, 360-407-9278; Enforcement: Local jurisdictions.
This notice meets the following criteria to use the expedited adoption process for these rules:
Corrects typographical errors, make address or name changes, or clarify language of a rule without changing its effect.
NOTICE
THIS RULE IS BEING PROPOSED UNDER AN EXPEDITED RULE-MAKING PROCESS THAT WILL ELIMINATE THE NEED FOR THE AGENCY TO HOLD PUBLIC HEARINGS, PREPARE A SMALL BUSINESS ECONOMIC IMPACT STATEMENT, OR PROVIDE RESPONSES TO THE CRITERIA FOR A SIGNIFICANT LEGISLATIVE RULE. IF YOU OBJECT TO THIS USE OF THE EXPEDITED RULE-MAKING PROCESS, YOU MUST EXPRESS YOUR OBJECTIONS IN WRITING AND THEY MUST BE SENT TO Diane Glenn, Chair, Washington State Building Code Council, P.O. Box 41449, Olympia WA 98504-1449, phone 360-407-9255, email sbcc@des.wa.gov, AND RECEIVED BY January 19, 2021.

For SI:
1 British thermal unit per hour = 0.2931 W, °C = [(°F) - 32]/1.8.
 
"Cap" = The rated cooling capacity of the product in Btu/h. If the unit's capacity is less than 7000 Btu/h, use 7000 Btu/h in the calculation. If the unit's capacity is greater than 15,000 Btu/h, use 15,000 Btu/h in the calculations.
a
Chapter 12 of the referenced standard contains a complete specification of the referenced test procedure, including the referenced year version of the test procedure.
b
Replacement unit shall be factory labeled as follows: "manufactured for nonstandard size applications only; not to be installed in new standard projects" or "manufactured for replacement applications only: not to be installed in new construction projects." Replacement efficiencies apply only to units with existing sleeves less than 16 inches (406 mm) in height and less than 42 inches (1067 mm) in width.
