New energy efficiency requirements for Part 3 buildings in British Columbia

As of late 2013/early 2014, new mid- and high-rise (Part 3) buildings in British Columbia have to comply with one of two new energy codes: ASHRAE 90.1-2010 or the 2011 National Energy Code for Buildings. These briefing notes examine the new energy efficiency requirements: Part 1 assesses the performance gains expected from these two standards in B.C., while Part 2 examines the key similarities and differences between the two standards.
