Outlines
🌿 Zero Carbon Innovation at The Joy Center
The Joy Center for Partnership and Innovation, established in 2018, is a pioneering zero carbon building in Canada. With a 96,000 square feet footprint and a $54 million investment, it is one of the largest of its kind. The center's design prioritizes energy efficiency and carbon offset through on-site renewable energy. Key features include triple-pane windows filled with argon gas to reduce thermal demand, architectural ceramic frit for bird protection and solar reflectance, and a 1980-panel rooftop photovoltaic system for power generation. The building maximizes natural light through large windows and a central light well, complemented by sensor-controlled LED lighting. The interior boasts natural finishes designed by local architects, avoiding materials that emit harmful gases. A solar thermal radiation system heats all domestic hot water without natural gas, using solar thermal panels and a heat exchanger. The building's airtight design requires only one air handling unit, which uses heat recovery and an enthalpy wheel for efficient air temperature regulation. Additionally, 32 heat pumps and 28 geothermal wells work in tandem to provide heating and cooling, while an electric temperature amplifier serves as a backup system.
💧 Sustainable Systems at The Joy Center
The Joy Center operates without natural gas-fired equipment, relying instead on a variable refrigerant flow (VRF) geothermal exchange system. This system includes heat pumps and geothermal wells that reach over 600 feet deep, regulating the building's temperature by exchanging heat with the earth. A slinky system installed underground absorbs excess heat as a safety measure. The center also employs a rainwater harvesting system, with two tanks capable of storing 228,000 liters of water for non-potable uses. The water undergoes a filtration process and UV disinfection before being used in toilets and urinals. Although the building utilizes rainwater for non-drinking purposes, it still receives municipal water supply for potable water needs.

Transcripts
The Joy Center for partnership and
Innovation was built in 2018 and was one
of the 16 Canada Green Building councils
pilot projects for the zero carbon
building standard
at 96 000 square feet the 54 million
dollar Center is Hamilton's first zero
carbon institutional building and one of
the largest in Canada
The Joy Center was built to the zero
carbon standard this means that it is
highly energy efficient and it produces
on-site or procures carbon-free
renewable energy to offset the annual
carbon emissions associated with the
operations how does the building do this
a high performance building envelope the
windows in the joy Center are triple
pane glass windows which means they are
three panes of glass side by side
separated by a spacer
and the center is filled with an inert
gas such as argon helping to minimize
the thermal energy demand intensity or
Teddy while maximizing heating cooling
and natural light
the windows have an insulation value of
around R8 and these white hexagons you
see here are an architectural ceramic
frit the pattern helps Birds avoid the
windows and it provides a solar
reflectance estimated to be about five
percent to reduce heat gain a rooftop
photovoltaic system or a PV system
The Joy Center is powered by 1980 solar
panels one third of them are on the roof
and the other two-thirds are on the rest
of the campuses flat roofs
this solar array feeds into an inverter
that allows the building to use the
power generated on-site
natural lighting
The Joy Center uses natural light to
reduce energy needed for the lighting
large insulated windows allow sunlight
to illuminate classrooms labs and
hallways
specially designed Central light well
allows natural light to flow through all
five floors sensor controlled LED
lighting detects sunlight and will dim
or turn off when there's plenty of
sunshine available
natural finishes
the interior finishes were designed by
local Architects McCallum say their
architects in partnership with b h
Architects using all natural materials
that don't off gas
solar thermal radiation system
all of the domestic hot water in the joy
Center is heated through the sun we're
not using any natural gas to produce hot
water instead the building uses a solar
thermal radiation system with five solar
thermal panels on an adjacent roof these
solar thermal panels help produce
domestic hot water for the building
occupants
these solar thermal panels look like
photovoltaic panels but instead have
tubing that goes through them containing
a glycol water mixture which warms up
and gets very hot on a sunny day
this hot mixture comes into the building
and goes through a heat exchanger for
safety reasons
hot water is produced in a preliminary
tank that contains a coil that heats up
the water and then it is stored in a
separate tank for distribution in the
building
air handling unit
Net Zero buildings need
s need the walls roof and the floors
have virtually no air leaking in or out
in a traditional building a building of
this size would need two to three air
handling units to be able to supply all
of the fresh air required throughout the
building
but because this building is designed to
be so airtight we only need one
in order to keep the air in the building
fresh 100 dedicated outside air is used
all of the air gets brought in through
this duct no matter the temperature
outside
in the winter heat exhaust from the
inside of the building is collected and
used to preheat the cold air that is
brought in
all the existing warmer air gets
captured and pumped through the air
handling unit they go through high
efficiency filters pumping in through
this enthalpy wheel which then warms it
up even further
this saves energy when heating or
cooling the air we bring in which
minimizes the need for natural gas
heat pumps
to heat and cool the building 32 heat
pumps are used a heat pump works like
your fridge the fridge produces the cold
temperatures inside but if you go to the
back of the fridge it gets warm in the
summer as the building is being cooled
these heat pumps work similar to your
fridge to cool the building and
producing warm water that we pump into
the 28 geothermal Wells to warm up the
ground below for storage and use in the
winter to heat the building
templifier electric temperature
amplifier
as a backup system for the heat pumps an
electric temperature amplifier was
installed this is used to pump a large
amount of heat all at once into the
building to reach temperatures up to
code
an example of one this is needed is in a
vestibule when you enter a building from
outside on a cold day
to combat the cold air being let in the
templifier will then kick on to balance
it out with hot air
geothermal Wells The Joy Center has no
natural gas-fired equipment that means
no conventional boilers and hot water
tanks and no furnaces instead it uses a
variable refrigerant flow or vrf Geo
exchange system with heat pumps and
geothermal Wells these Wells go down
over 600 feet the supply and return
pipes lead from the wells into the
building and all of the supply from the
bore field comes here
we track the temperature to see that the
supply to the bore field is higher in
the summer and lower in the winter
this system is similar to the solar
thermal system where the glycol solution
comes into these heat exchangers and is
returned out
from here the water is pumped up to the
penthouse
to those heat pumps to be warmed even
further
so this paired with the heat pumps and
the air handling unit all combined to
give us the heating for the building
there's a balance though and for the
geothermal system you can't overdo it
and try to store too much heat as a
safety precaution a slinky system was
installed a few feet below ground this
will absorb the excess heat allowing the
heat to dissipate out of the ground
careful operational oversight avoids
this potential problem
rainwater harvesting system
the building uses rainwater harvesting
for all non-potable water with two
storage tanks holding 228 000 liters of
water the tanks are right here behind
this wall
you can see the pipe where it comes from
it comes in and is then pumped into our
filter system
there's two sets of filters the first
one 100 microns takes out all of our
seeable grit and the second one five
microns takes out anything that is
bacteria sized that you can't see
from here it goes to the UV disinfectant
which disinfects it and then goes to the
storage tank
this water goes to non-potable fixtures
so toilets and urinals
we do testing for the water at each
stage as well just to check up on it and
see the difference
there is still municipal water that
comes in for the potable drinking water
