For new and existing homes
EnerGuide (ERS) is an energy rating system for houses 0 – 100 scale
The average new home would rate of 78 – 80
1981 R-2000 ERS 80 or better
Houses that produce as much energy as they consume are ERS 100
50% reduction in space

Building Codes
National Building Code with energy
efficiency requirements published 2012 –
Adopted NB 2015
(Similar to EnerGuide 80 or the 1981 R2000
energy target)
National Energy Code for Buildings
Not adopted in NB to date
Progress to Date
EnerGuide existing homes
34,036 homes/apartments
R-2000 & EnerGuide New Homes
6,298 registered
Net Zero Homes
Passive Houses
Large uptake in periods of incentive programs
Challenge Ahead
340,000 existing housing units
10% retrofits existing units (34,000)
90,000 housing units built since 1981
(2,200-3,500 new housing units/yr)
7% EE new housing units (6,300)
Challenge Ahead
Roles of a Conservation, Efficiency and
Renewables Agency
Continue the move to lower energy housing
Prepare the NB market for coming changes
Support training/ demonstration projects
Provide sound, credible advice
