“WE’RE IN A RACE
AGAINST TIME TO HIT
THE PROVINCIAL AND
FEDERAL EMISSION
REDUCTION TARGET,
WHICH IS BASED ON
THE PARIS AGREEMENT,
SO WE NEED TO
TRANSITION TO ZERO
CARBON AS SOON
AS WE CAN”

Supervisor, Energy Management,
City of Brampton
with heating.” Aside from utilizing
sustainable energy, such measures
have the knock-on effect of improving
the experience of citizens, as with the
natural light provided by daylighting.
“These are the types of things that we
also look at. It’s not just about energy
effects, but also occupant comfort.”
Such measures are to play a vital
part in achieving the city’s ambitious
Zero Carbon Transition Plan. “The
provincial government has set a target
of 30% emissions reductions by 2030,
and the federal government has set an
80% reduction target by 2050, which
is in line with the Paris Agreement to
limit the global temperature rise to 1.5
degrees Celsius by 2050. Our Zero
Carbon Transition Plan is predicated
around these targets. We’re looking at
reducing our energy use for new and
existing buildings by 30% by 2030.
We’re targeting various measures:
heating, ventilation, air conditioning
systems and building envelope.
We’re going to use heat recovery:
recycling waste heat wherever
possible. Once you get the energy
demands of the building down, then
the next step is to look at renewable
technology. That’s the most efficient
way to approach it. It’s energy
management 101.” Other innovations
geared towards meeting the city’s
targets include innovations in passive
heating. “The SolarWall is a matte
black surface that can be put on top of
a building’s exterior wall, leaving an air
gap,” says Liang. “The sun hits this
black surface, and transfers energy to
the wall and air gap. The air is heated
in that gap and then brought into the
building to preheat the air for ventilation.
“We expect to verify the energy savings
