energy profile of new Housing - Yellowknife 2010-2015

Based on the work of Asok Thirunavukarsu, M.A.Sc. Concordia University, summer project 2015 

The NSERC Smart Net Zero Energy Buildings Research Network (SNEBRN) is a Canadian research effort that includes 29 Canadian researchers from 15 universities and researchers and experts from NRCan and, industrial partners from the energy and construction sectors. The AEA was asked and joined SNEBRN as a network partner.

The AEA is attempting to guide Northern research by having research conducted in the North for the North. Most recently, Asok Thirunavukarasu, a Master’s student from Concordia University spent time in Yellowknife on an independent research project regarding energy efficient housing in Yellowknife, in collaboration with AEA

Asok's field work included on-site evaluations, occupant and builder interviews, and benchmarking housing energy performance using the NRCan Energy Rating Service ERS (formerly referred to as EGH) evaluation data. He data mined the AEA’s ERS database which included years of ERSs. The fieldwork portion of  his research in Yellowknife aims to find out if the City's ERS 80 standard is improving overall energy intensity. The results of his research showed that the City of Yellowknife EGH80 Bylaw contributed to 91 new homeowners collectively saving $272,000 a year with most of the savings coming from avoided heating costs. The most notable changes subsequent to the EGH80 Bylaw occurred with building tightness (less drafty),and  increased wall and ceiling insulation levels.

The research included 1,744 homes from the Arctic Energy Alliance ERS database were (of which 1,002 homes were from the City of Yellowknife). Included were homes built in 2015, and the last evaluation date was July 1st, 2015.
