  • 1. The Ins & Outs of Energy Efficiency in the Building Code Bob Bach, P.Eng. Senior Consultant Energy Profiles Limited Sustainable Buildings Canada July 18, 2013
  • 2. Overview  Role of the Building Code Conservation Advisory Council  Where the Building Code is in 2012  Where the Building Code will be in 2014  Where the Building Code could be in 2017  Other Changes in Sight
  • 3. Building Code Conservation Advisory Council  Formed in 2010 with representatives from AMO, BILD, BOMA, CEEA, EGD, LMCBO, NAIMA, OAA, OHBA, SBC, UGL.  Role is to provide strategic advice to the Minister on energy and water conservation, barriers to green technologies, promote on- site generation of renewable energy, and how to enhance industry capability to implement conservation.
  • 4. OBC 2006, Part 12 (Part 9 Residential) 12.2.1.2.
