Oregon 2011 Residential Code Update Effective July 1
The Oregon Building Codes Division (BCD) has issued a rulemaking notice updating the state’s residential code to the 2011 Oregon Residential Specialty Code (ORSC). The energy efficiency section (Chapter 11) updates Chapter 4 of the 2010 Oregon Energy Efficiency Specialty Code (OEESC) approved last year. It is intended to achieve 10-15% greater energy savings than the 2008 ORSC, as directed in 2009 by SB 79.
The new code will take effect July 1, 2011, although there will be a 90-day transition period when the old code (2008 ORSC) may still be used. Oregon previously updated its commercial code in July 2010 and has been developing optional “reach” codes for energy efficiency. The 2011 ORSC is available online for free.
