10. Biomass can be a responsible
choice if…
The heating system is installed
safely (WETT Certified Professional)
Fuel is harvested sustainably
The fuel is burned efficiently with
little or no visible smoke

11. Home Heating Appliances
Current Technologies:
• Advanced Wood burning: Wood Stoves, Wood
Fireplaces, Wood Inserts and Wood Furnaces
• Pellet Stoves, Pellet Fireplaces, Pellet Inserts and
Pellet Furnaces
Emerging Technologies

12. Firewood – good fuel is the secret to
efficiency.

13. Advanced Wood Burning
Technology
Advanced technologies offer several
advantages, including:
Much higher efficiency
Much less smoke pollution
Greater safety because less creosote is
formed
Burn less wood for more heat. Five acres of
wood can support a home forever

14. Convention wood stoves

15. Advanced Technology Wood

16. Two types of Advanced
Combustion:
1. Catalytic
• uses catalyst to clean up exhaust
2. Non-catalytic advanced
• most common type in Canada

17. Inside a catalytic wood stove
Smoke passes through a catalytic honeycomb
that lowers smoke ignition temperature

18. Inside a “non-cat” wood stove
1. Firebox insulation 2. A large baffle
3. Preheated combustion air

19. Compare old with new

29. Space Heating
Studies have shown that most families spend
80% of their time in a couple rooms of the
home (20% of the house)
By heating the space that we live, with a high
efficiency product, in we can reduce our
consumption by 28%

30. Carbon Emissions Savings
Solar Hot Water - 1
ton/year/2 panel system
2 Kilowatts of Solar/Wind
– 1 ton/year
Space Heating 28%
Biomass Heating - 2-5
tons/year

31. Where are we going?
With more focus on climate change, our community is
becoming more aware of “Green Technologies”.
We are expanding, hiring more people.
Continue to introduce environmentally appropriate
technologies to homeowners.
Work with organizations to share our knowledge.
To help with the “greening” of our community.

32. Conclusions
Burning wood and plant matter is “carbon neutral”.
Using advanced combustion appliances a home can be heated
with less than 5 acres of wood and less than 2 acres of switch
grass.
Locally grow and harvested fuel is how we will heat our homes
in the future.
Using biomass as a heating option has a fast payback and can
save up to 5 tons of carbon per year.
SAFETY IS PARAMOUNT.

Getting Your Project Done
Case Study
Questions and Follow-up

62. Introduction
•Canada’s per capita daily water consumption is 65% above the
world average!!!
•The average Canadian uses more than 335 litres of fresh water
per day.
•10% of the home’s water usage is in the kitchen and for
drinking water.
•½ to ¾ of summer municipal water usage is to irrigate the
house’s lawn.

63. Definitions
•Graywater collection refers to waste water
collected from bathroom sinks, bathtubs,
showers, and clothes washers.
•Kitchen sinks cannot discharge into a
graywater system. Know as Blackwater.
•Rainwater collection refers to the harvesting
of rainwater fall into storage units. This stored
water maybe used for irrigation outdoors and
flushing toilets, laundry and if filtered for
drinking.

64. Benefits of Graywater Collection
•Reduces demand on groundwater or municipal water supplies.
•Reduces demand on septic and municipal wastewater treatment
systems.
•Reduced sizing of septic system.
•Reduces energy costs.
•Increases lifespan of stressed septic systems.

65. Benefits of Rainwater
Harvesting
•Reduces demand on groundwater or municipal water supplies.
•Serves as a stormwater management alternative by reducing
volume, velocity and peak flows of stormwater runoff.
•As stormwater is controlled, flooding and streambank and channel
erosion are reduced.
•Less stormwater runs over hard surfaces, decreasing the
impurities in the stormwater runoff.
•Less buildup in your appliances.
•Upwards of 33% of a city’s electricity use is to pressurize the water
delivery system.

66. Available Graywater Systems
• Whole Building Systems
•BRAC Systems from Quebec
http://www.bracsystems.com
•Single Function Systems
•Water Saver Technologies of KY, USA
produce the Aqus – a single flush toilet unit.
http://www.watersavertech.com

67. Available Rainwater Systems
•First Flush Systems
•Refers to the devices that divert the initial rainfall away from the
storage system.

68. Available Rainwater Systems
•Rain Heads
•Refers to the devices that divert the larger items, such as leafs,
twigs and waste, from the storage system.

69. Available Rainwater Systems
•Storage/Containment
•The storage system can come in a multitude of configurations
from above ground, to below ground to modular.

70. Available Rainwater Systems
•Accessories
•Various other components become part of a built-up rainwater
harvesting system.

71. Installation Issues
System Sizing
•Approx. 0.62 US gallons per square foot of
collection area per inch of rainfall can be collected.
•Losses occur due to first flush, evaporation, gutter
overflow and overshoot along with any leakage.
•Therefore system efficiencies are calculated at
between 75% and 90%.
•The collection area is calculated as the footprint of
the roof regardless of roof slope or pitch. Area is roof
length times width from eave to eave front to back.

72. Installation Issues
System Sizing – Storage
•Simple method is to size
storage to meet ¼ of
required water demand.
•Large storage capacities
require additional expenses
therefore water conservation
becomes a larger factor.
•Estimating demand – the
normal water conservative
household uses between
100 to 200 litres per person
per day. Decide which
services will use collected
water.

73. Installation Issues
Building Code
•In the 2006 Ontario Building Code was amended to allow the
usage of graywater to flush toilets and for irrigation. These
measures where changed along with the Solar PV and Solar
Thermal technologies.
•Always check for additional requirements from local authority
having jurisdiction.
•Note all rainwater and/or graywater piping must be clearly
indentified.

74. Installation Issues
Other Considerations
•Storage tank should have potable water makeup supply
hooked up. Pumps maybe damaged by running in a dry
condition.
•Consider if storage capacity is adequate for fire protection.

75. Cost Calculations
•Can be as simple as adding up costs for individual
components and deciding what one and afford.
•Largest single expense will be the price of the storage
containment. Costs range from a low of $0.50 per gallon for
fibreglass to $4.00 per gallon for welded steel containers.
Generally as tank size increases the price per gallon
decreases.
•Filtration will range from $50.00 to $1000.00 dependent
upon level of filtering required. (ie roof type, trees, water use).
•Pump costs will run between $400.00 and $1200.00.

76. Getting Your Project Done
•Assessing Needs
•What will you use the recovered water for?
•Specification of Equipment
•Above ground or below ground?
•Acquiring Approvals
•Check with local autohority
•Project Planning
•Space available?
•Engaging Contractors
•Experience? Product availability?
•Follow-ups & Maintenance
•Water usage? Type? Level of purity? Filter style?

77. Case Study
•Kingston Police Station – LEED Gold
•Reduced indoor water consumption by 71%
•A 82% reduction in water used for sewage conveyance
•Rainwater used to flush toilets.
•Annual water savings of close to 2 million litres of potable
water annually.
•Reid’s Heritage Homes – Guelph – LEED For Homes Program
•Uses 1,500 gallon cistern for 100% storage of rainwater
•Supplies toilets, dishwasher, laundry and underground
sprinkler
•Estimated 40% reduction in municipal water usage.

78. CONCLUDING REMARKS:
Greywater now supported for
toilet flushing and irrigation.
Need to check with local
authorities.
Need to implement water
conservation.
Water will become the new ‘oil’!!
