A 30-unit housing development in Prince George is BC
Housing’s first development to achieve LEED Gold
certification. Operated by the Prince George Native Friendship
Centre, Friendship Lodge provides housing to low-income tenants,
some dealing with addiction and mental health issues.
“Friendship Lodge is also our first
LEED Gold certified building,” said architect Anthony
Boni, Partner, Boni-Maddison Architects. “Building to
these standards requires a collaborative approach between all the
partners. A common vision needs to be established at the beginning
of the project and carried through the entire design and
construction process.”
The building was carefully planned to minimize
energy use, reduce water use, improve indoor air quality and
thermal comfort, and incorporate resource efficient
materials.
-
Environmentally sustainable design features include a
geo-exchange system, or ground source heat pump, that provides
heating and cooling to the interior space, as well as domestic
hot water production.
-
Ventilation air is ducted directly to suites instead of
typical corridor pressurization. The exhaust air is used for
heat recovery where it is fed back into the main heating
loop.
-
Materials were selected to minimize VOCs
(volatile organic compounds) and other air contaminants in
order to maintain good indoor air quality and occupant
comfort.
-
Locally manufactured materials and
energy-efficient windows and lighting were used throughout.
-
The building’s asphalt roof shingle
reflects light from the sun, thus reducing the impact of heat
islands on the local microclimate.
-
Full cut-off light fixtures are used on the
building’s exterior to reduce light pollution.
-
Irrigation for the planting beds is fully
supplied by natural rainfall and/or collected rainwater stored
in barrels.
Anticipated energy cost savings of these and
other measures are 54 per cent, with greenhouse gas emissions
reduced by 49 per cent, and water use reduced by over 53 per cent
over traditional construction methods.
“The building has lots of great bells
and whistles, but when it comes right down to it, it’s
what these mean to the residents that really count,”
added Boni. “One of my best memories of working on
Friendship Lodge is the excitement the residents expressed when I
reviewed the features with them. They really care that they live in
a place that is energy efficient.”
