FOR IMMEDIATE RELEASE:
City of Richland approves use of the 2009 International Energy Conservation Code
The City of Richland is hereby approving the use of the 2009 International Energy Conservation Code (IECC) as an approved alternate to the 2009 Washington State Energy Code (WSEC) during an interim period while the State Building Code Council (SBCC) resolves pending lawsuits and other problems with the adoption of the 2009 WSEC. The 2009 IECC may be used for residential or commercial buildings. When used for commercial buildings, the City encourages the use of the supplemental and coordinated “International Green Construction Code” (IGCC) which was adopted by the City in July 2010 as a reference code. The City of Richland is implementing this temporary policy for at least one year, until January 2012, to allow builders, developers, architects, and engineers, enough time reasonably to use and apply the 2009 IECC to their various projects, both residential and commercial. Since residential builders have been anxious to know what energy requirements will apply to new homes, we are excerpting some requirements of the 2009 IECC below. We encourage builders to obtain a copy of the 2009 IECC and peruse other detailed requirements. The City also strongly encourages residential builders to investigate and use the “Built Green” program offered by the Home Builder’s Association of the Tri-Cities, as this program is an excellent method of achieving high energy efficiency and sustainability in our community.
City of Richland is in Climate Zone 5B (5-Dry) requiring the following insulation, window, and door energy-efficiency values for RESIDENTIAL construction.
Table 402.1.1 from 2009 IECC (Residential)
| Window U-value | Door U-value | Skylight U-value | Ceiling Insulation | Wall Insulation* | Floor Insulation | Slab Insulation |
| 0.35 | 0.35 | 0.60 | R-38 | R-21 | R-30 | R-10 for 2ft. |
*Note: Since the IECC only requires R-20 and R-21 has been the common practice for many years, the City will continue with the R-21 common practice for wall insulation.
Concerning the air sealing requirements, the 2009 WSEC created controversy with the mandated blower door testing requirement. The 2009 IECC offers two options, EITHER the blower door test OR visual inspection by the City. Since the City has done this visual inspection for many, many years, we will continue to do so without increasing permit fees in order to promote affordable, yet energy efficient, residential construction.
402.4.2.2 Visual inspection option. Building envelope tightness and insulation installation shall be considered acceptable when the items listed in Table 402.4.2, applicable to the method of construction, are field verified. Where required by the code official, an approved party independent from the installer of the insulation shall inspect the air barrier and insulation.
The City has a detailed justification for this temporary, alternate code approval that includes many varied reasons. You may request a listing of these reasons through the Request for Public Information process. We readily admit that there may be things in the 2009 IECC that may be different than common practices here in the Tri-Cities, and so we ask everyone for their help in identifying any requirements that appear unusual. We can then discuss them with you and figure out what to do specifically or generally.
Thank you to all who have helped in coming to this policy decision on energy codes for the coming year. Special thanks to the local builders and suppliers for their patience while the City researched these energy code issues.

1. During the WSEC revision cycle, the SBCC tried to reach a goal of 30% energy savings over the 2006 WSEC. They fell well short of that goal, somewhere in the range of only 15% better than the 2006 WSEC with their 2009 WSEC. The 2009 IECC meets this range, being approximately 15% better overall in energy saving features for both commercial and residential construction, as verified by at least two independent sources (see “Meeting the 2030 Challenge Through the Building Codes” from Architecture 2030 and the graph entitled “LEED, ASHRAE, ICC Comparison” from ICC), while still meeting Federal guidelines for mechanical equipment efficiencies (see item #4 below).
2. The SBCC did not follow important legal requirements for adopting the 2009 WSEC as noted by Joint Administrative Rules Review Committee (see WAC 51-11 published by the Office of the Code Reviser through the following web-link http://apps.leg.wa.gov/wac/default.aspx?cite=51-11-0101) which caused the building industry and code officials many concerns during the past year. In June of 2010, Governor Christine Gregoire requested that the SBCC temporarily suspend the implementation of the 2009 WSEC until April 2011 so that the SBCC could correct the adopting deficiencies. The SBCC did not do so during the temporary suspension, but only overrode the governor’s request and made an even earlier implementation to January 2011, thus not allowing jurisdictions (let alone the building industry) time to even understand the new version of the WSEC.
3. A motion by Mr. Don Jordan from a May 7, 2009 meeting of the SBCC, which was unanimously approved by them at that meeting, was never implemented in the final version of the 2009 WSEC, creating confusion in the WSEC about what energy provisions apply to duplexes, townhouses, and live-work units. The 2009 IECC is coordinated with the other International codes to resolve this conflict.
4. The “pick list” included in the new Chapter 9 of the 2009 WSEC requires HVAC and plumbing equipment to have efficiency standards higher than federal government standards. Not only is this prohibited by Federal law (a prohibition set in place to allow manufacturer’s of HVAC and plumbing equipment to have a set standard for design and manufacturing nationwide), but the practicality of obtaining such equipment is difficult and expensive at best and sometimes such equipment is not available at all for residential use. The 2009 IECC has received Department of Energy approval as equivalent to the ANSI/ASHRAE/IESNA 90.1 Standard and use of the 2009 IECC was endorsed in various 2009 economic stimulus bills of the Federal government.
6. RCW 19.27A specifically adopts the 2006 WSEC for residential buildings, and states that such is both a minimum and a maximum standard, implying that a very strict legal standard must be used when changing that code. Such strict legal standards were not followed by the SBCC as they moved through the adoption cycle for the 2009 WSEC. Since RMC Title 21 relied heavily on the SBCC to adopt properly the state building code by allowing continual, automatic City adoption of any state amendments and codes, the City of Richland now has an obligation, a public duty, to take some temporary action in finding an energy code that meets federal requirements as well as provides for increased energy efficiency, especially for new residential buildings within the City of Richland.
