of Ottawa requires all newly constructed city buildings with a footprint larger than 5,000 sq. ft. to be
designed at minimum to a LEED-certified standard.
Both fire stations were built to LEED Gold standard
and are undergoing the process of certification.
Other sustainable features incorporated into the
design include:

GLASS THAT

STANDS OUT

* high overall building-envelope performance
* increased insulation values throughout roof and
wall assemblies

* fiberglass windows with high-performance glass
* daylighting throughout every room in the facility
promoting natural light and ventilation into most
spaces

* use of regional and recycled materials
* mechanical and electrical systems that exceed energy performance standards.
In addition to improving emergency services to
the community, the City of Ottawa's goal when constructing these facilities is to ensure they will perform
for the long term with minimal maintenance.
"Energy efficiency and durability are what we
focus on more than anything," explained Shawn
Lynch, project manager for the City of Ottawa.
"When you're spending public money, you want the
buildings to last. We're all about designing buildings
that you don't have to go back and fix later. And you
can't get any more durable than a steel roof."
