Ottawa measures energy
efficiency in Iqaluit
How much fossil fuel
does your home burn?

With his long white hair
and black equipment cases, Ross Elliot could be mistaken for a musician.
He and two others knock
on the door of an Iqaluit home and go inside. But they are not there to play
instruments, they are there to read them.
Elliot is one of two specialists
contracted by Natural Resources Canada to conduct tests on about 60 homes in
Iqaluit this week. The homes will be rated on their energy efficiency and a
report issued showing where improvements can be made.
This evaluation, called
Energuide for Houses, comes from the Office of Energy Efficiency under the federal
department of natural resources.
The evaluation is only
done on single-family dwellings, or ones that are side-by-side.
By improving the energy
efficiency of buildings, this evaluation is intended to reduce greenhouse gas
emissions and the environmental impact of low-rise housing.
This increased energy efficiency
can also mean saved dollars for homeowners and property managers who will spend
less money on fuel.
Elliot takes equipment
from a variety of round and rectangular cases and assembles a black frame that
fits the doorway. He attaches it to a large red piece of material that is then
inserted where the door was.
This material, which is
strong enough to keep the cold out on a -32 C day, billows a bit with the wind.
Three gauges hang by hoses to a large fan fitted into the new red material door.
Elliot turns the fan on
and begins the blower door test. As air is sucked from the house, a vacuum is
created, and this causes outside air to be sucked in through any leaks.
The gauges measure the
pressure and the data they collect is recorded and entered into a computer program,
which eventually generates an EnerGuide rating for the home.
A report accompanies the
rating and gives suggestions of what building owners can do to cut costs, as
well as give an estimate of how much renovations would cost.
Factors like the number
of people living in a house and their ages can be taken into account in the
report, but, for the rating, all houses are treated equally.
Raynald Charest, with the
office of energy efficiency, says the rating between 1 and 100, with
"100" meaning the building is completely powered by solar energy
has the same meaning as an EnerGuide label on appliances like washing machines
and dryers. According to this rating system, a house rated "50" is
not as energy-efficient as a house with an "80" rating.
The energy used in Nunavut,
whether it is from burning fuel or from electricity derived from fuel, releases
significant amounts of carbon dioxide into the atmosphere. While reducing these
emissions is good for the environment, it can also be lucrative for building
owners.
Neither Nunavut nor the
Northwest Territories has offered EnerGuide for houses before, although this
evaluation service is already available in the Yukon.
The Yukon Housing Authority
offers better mortgage rates if a building receives a higher EnerGuide rating
and some utilities, especially in the U.S., have also shown interest in giving
energy credit transfers to customers who increse their energy efficiency.
After the blower test is
completed, Elliot walks through the home checking for drafts. He reappears to
get his flashlight and says hes going to check out the attic.
Public Works Canada and
Natural Resources Canada are spending about $12,000 to have about 60 rental
units rated in Iqaluit. Charest says he hopes a local delivery agent can be
found to do ratings on other units in the future.
In the South, where the
program has been running for years, Natural Resources Canada buys the data collected
from delivery agents like Elliot for $150. Data collected in the Yukon costs
them about $225.
Steve Cook, general manager
of the property company Nunastar, says the EnerGuide rating program is a good
idea and he could see it being used in Nunastars White Row units in Iqaluit.
"We know some of the
things that need to be done because of the age of construction," Cook says
of increasing energy efficiency in those units.
But its the question
of how long it will take for the company to recoup the cost of renovations with
energy savings that remains hanging.
"Because of the nature
of communal heating," Cook explains, "the fuel costs dont always
get passed on to the tenant in a reasonable fashion if theyre under lease."
So the company ends up
picking up any increased costs.
"If we were bidding
on units to lease out to the government, for example, and we were able to maximize
our energy savings that would be passed on we would be able to be more competitive
in our pricing," Cook says.
