Mandate: Reduce building energy consumption 70 percent over 25 years. • The Washington state legislature and the Governor’s Office
have directed the State Building Code Council to adopt energy codes to reduce energy use in newly constructed residential and nonresidential buildings.
• Federal Law also requires the state to meet minimum energy savings standards.
• Building energy efficiency is the single largest factor in the region’s future electric needs.
• Reduction of 70% by 2030 as compared to the 2006 Washington State Energy Code
• R104.2 Inspections– Revised to list and describe the required insulation inspections as:• Footing and Foundation inspection• Framing and Rough-‐in inspection• Wall inspection• Plumbing Rough-‐in inspection• Mechanical Rough-‐in inspection
– Final inspection shall include verification of the installation of all required building systems, equipment and controls and their proper operation and required number of high efficacy lamps and fixtures
R401.2 Tools for Compliance • Prescriptive• Total UA Alternative – WSU form *• Performance Approach – as required in R405
Check WSU’s Energy Code webpage for compliance tool information as it becomes available: www.energy.wsu.edu/code
NOTE: Energy Rating Index (ERI/HERS Index) is not an approved compliance path in WA state.
*REScheck no longer available in WA State
Prescriptive Form (ATTACHED)
• R401.3 Certificate (IECC change) Editorial changes for clarity, allows more flexibility in the placement of the certificate.– A wall in the space where the furnace is located, a utility room, or an approved location inside the building. (was within 3 feet of the electrical panel)
NOTE: No change to required content for compliance certificate
• R402.4.4 Combustion air (IECC) new sectionrequires:–Mechanical rooms with outside combustion air ducts providing combustion air to open combustion shall be located outside of the building thermal envelope or enclosed in a room isolated from inside the thermal envelope.

combined maximum air leakage rate of 7 ACH. To qualify for this exception, the date of construction of the existing home must be prior to the 2009 WSEC.
• Ducts outside the building thermal envelope shall be insulated to a minimum of R-‐8 (same).
• Ducts within a concrete slab or in the ground shall be insulated to R-‐10 with insulation designed to be used below grade. (was R-‐8).

Administrative PoliciesLead/Silica Rules – L&I Rule Status
WISHA Safety Plan
Lead Rule Stakeholder Meetings “Hiatus”
• There will be no changes to the current lead rules in WA State for 6 mos to 2 years. Must continue to comply on Federal and Tribal Job Sites.– Goal is to eliminate BLLs (blood lead levels) in all adults that are higher than 10 μg/dl (micrograms/deciliter). Currently can still be on job site at 50 μg/dl
– Discussion included employee baseline lead level medical exams of certain occupations, increased personal protective gear, employee training requirements, engineering and work practice controls
– Setting 3 levels of “Trigger Tasks” – L&I hiring new FTE
Lead Based Paint• Under the United States Environmental Protection Agency’s Lead-Based Paint
Renovation, Repair, and Painting (RRP) Program. Construction firms must apply for and receive EPA Certification to disturb paint as part of their work in pre-1978 housing and child-occupied facilities.
• Anyone disturbing more than 6 sq. ft. (interior) & 20 sq. ft. (exterior) of lead-based paint must get the training.
• BIAW Education offers Certification and Recertification classes.• THE FINES HURT! Firms who knowingly or willingly violate the RRP
Program requirements could face penalties of up to $10,000 per day, per violation and/or face imprisonment.
• Rulemaking begins: Department of Commerce wants to increase certification fees. First meeting for stakeholders is June 29 1:30-3:30 in Olympia.
Member Question
• If the General Contractor is lead certified doing work in a pre-‐1978 home, do sub-‐contractors need to be lead certified as well?
• No, if the General Contractor did all the demo and cleaned up the site of all lead dust and debris prior to the sub beginning their work, sub does not have to practice lead safe work practices and does not have to be a RRP (Renovation, Repair, and Painting) certified renovator or firm. – DanoSummers, Dept. of Commerce

Crystalline Silica
• No statewide requirement (yet) Federal and Tribal jurisdictions only.
• OSHA issued final rule March 25, 2016– Effective June 23, 2016• Construction Employers have until June 23, 2017 to comply.
The standard applies to all occupational exposures to respirablecrystalline silica in construction work, except where employeeexposures will remain below 25 micrograms per cubic meter ofair (25 μg/m3) as an 8-‐hour time-‐weighted average (TWA) underany foreseeable conditions.
• Examples of tasks with low exposures include; mixing mortar; pouring concrete footers, slab foundation and foundation walls; removing concrete formwork; and finishing drywall.
• Permissible Exposure Limit (PEL)
• Workers must be protected from respirable crystalline silica exposures above the permissible exposure limit of 50 μg/m3 (micrograms of silica per cubic meter of air), averaged over an eight-‐hour day.
Specified Exposure Control Methods (Table 1)
• Employers can either use: 1) a control method in Table 1 of the construction standard; or 2) they can measure workers’ exposure to silica and independently decide which dust controls – if any are required –work best to limit exposures on the jobsite.
Working in Federal and Tribal jurisdictions
• Written exposure control plan• Medical Surveillance• Hazard Communication Plan• Training• Recordkeeping
Fair Labor Standards Act• US Dept of Labor issued a new overtime rule that goes into
effect Dec. 1, 2016. • Where differences exist between WA State and new Federal
overtime regs, an employer must follow the regulation that is most favorable to the worker.
• New rule did not change salary basis or standard duties; did increase salary level criteria. Doubled annual salary level: was $23,660 now $47,476
• Salary threshold will be adjusted every 3 yrs. • Employees will be due time and a half if they make less than
$47,476 and work more than 40 hrs/wk. – $913/wk (up from $455/wk)
• Outside Sales Staff are exempt.
Congressional Action
• Lawmakers have introduced the “Protecting Workplace Advancement and Opportunity Act.” (S. 2707 and H.R. 4773)
• NAHB requests contacting WA State members of Congress and ask for support of these bills.
• Susan Del Bene (1st), Rick Larsen (2nd), Jim McDermott (7th) and Adam Smith (9th)

Top 10 Construction Industry Violations
WISHA Safety Plan• All employers in Washington State are required to create a written
Accident Prevention Program (APP).
• To meet written program and other APP requirements, businesses need to do the following:– Look around to identify workplace hazards that could hurt employees.– Find and apply ways to reduce or eliminate hazards.– Provide a detailed safety orientation to employees so they
understand the possible hazards of their particular job and how to work safely.
– The Consultation Section of the Department of Labor and Industries may be called on for assistance at any time. If you would like information or help in setting up your individual program, please feel free to call the toll-‐free number: 1-‐800-‐423-‐7233.
