the building and repurposing of its
constituent components at the end of
building’s useful life. This increases
its resiliency to change and reduces
its total cost of ownership.
Lighting. The building has two narrow wings connected by an atrium
and auditorium in the middle. Each
of the wings is just 30 ft ( 10 m) wide,
with large windows that open, providing natural light and fresh air for all
building inhabitants when conditions
allow it. The result is a building that’s
bright inside even on cloudy days.
In the offices and labs, when the
amount of available daylight isn’t sufficient, artificial lighting is available
through addressable and programmable fluorescent lighting fixtures (using
a controller in combination with the
building management system [BMS]).
Lighting levels are controlled by photocells and through motion sensors
mounted directly on the fixtures that
turn the lamps off when unneeded.
Additionally, these lamps can be
de-energized through individual
relays installed in electrical panels.
These relays are controlled by the
Classrooms and meeting room
lamps are controlled by on/off
switches. In the lobby/atrium, fixed
and pendant lamps are controlled by
photocells. Lighting in public spaces
is programmed according to the
building operation schedule, which
also eliminates unnecessary use at
night and during unoccupied days.
Using Plants in the Envelope. On the
west exposure of the building a metal
armature supports deciduous vines
that form a vegetated façade. It shades
the building in the summer and
allows heat and light in the atrium/
lobby during the winter.
A living roof of local, well-adapted
plants sits on top of the auditorium.
The green roof retains a significant
amount of the storm water runoff
CIRS showcases the integration of a
host of off-the-shelf sustainable systems and technologies, such as water
harvesting, a vegetated façade and
solar shading components fitted with
integrated photovoltaic (PV) panels.
The design team engaged in an integrated design process that included a
3-D design model. Sustainable design
goals were organized into four categories: design principles; water supply
treatment and reuse; daylighting and
solar shading; and energy modelling.
The design charrettes included
technology partners, who came to the
table with ideas and technologies to
consider. These charrettes were partially funded by Natural Resources
Canada and compiled into comprehensive reports that are available on
the CIRS website, www.cirs.ubc.ca,
as well as in a detailed integrated
design process report.
Before considering energy efficiency
measures and the proper sizing of
mechanical and electrical systems and
components in the building, the design
team worked to reduce energy and
water demand to the absolute minimum through passive design strategies.
The team also maximized harvested
energy and water from “free” sources,
such as waste thermal energy, renewable energy and rainwater.
The CIRS four-story atrium is the heart of
the building. It is flooded with daylight, is
naturally ventilated and is heated through
in-floor hydronic tubing. It is the circulation
backbone of the building, functions as a
gathering space for building inhabitants,
and hosts a variety of events.
