This Blog is about the design and building of one of the first Passive House projects in Toronto. We are converting a 60 year old Bungalow in to a 2 storey House with a 2 nd suite. Using all the design aspects of the German standard for a Passive House.
"WHO says a Passive house has to be fun and boring? It can be fun, too!"
The Master on suite will feature a sunken Tub overlooking the back yard
and a Wall hung toilet. The custom shower will have a sunken floor as well
with a build in bench and some niches for storage with frame less glass enclosure.
The issues of energy saving and energy efficiency with the new Energy Conservation Ordinance 2009 still firmly anchored in law, then rise in the next year, the energy requirements for thermal insulation by 30%.
These requirements are easily achieved with our triple-insulating glass, as:
Triple-insulated achieve extremely low Ug-values up to 0.4 W / m² K.
Window cross section with foam insulation and swiss spacer
The above Wall cross section shows the eliminations of thermo bridges by staggering studs and sill plattes and applying a continuant layers of Foam board over exterior surface of wall. Also there will be no switches or outlets, wires or pipes in the exterior wall surfaces. This New Wall construction has 20 times more insulation value with no Air leakage than the existing 12" Brick wall with 1" air space R 3 and plaster on inside. and is less in thickens.
PAUL Comfort Ventilation is a leader in the field of mechanical ventilation heat recovery (MVHR). Established in 1994, PAUL has pioneered the development of highly efficient, very quiet, domestic heat recovery units, alongside applying the same standards to commercial sized units.
Combining their patented channel counter flow heater exchangers with the very latest in low energy dc silent fan technology means that PAUL units achieve the very highest standards. PAUL products have both SAP Appendix Q listing and Passive House Institute certification.
Real energy savings
Lower heating bills
Constant fresh air
Low pollen levels
Cooling in summer
Constant odour & dust mite removal
No mildew or mould
In ground loop for fresh air intake
The Heat Exchanger
The heart of every PAUL Comfort Ventilation system is the heat exchanger. This is where the heat from the outgoing air is transferred to the incoming air. This works both ways so if the outside temperature is higher than inside the exchanger helps to maintain a constant pleasant internal climate.
The unique patented PAUL counter flow heat exchanger design has proven itself to be one of the most efficient on the market. Combined with a surface area of 60m² in the family house size units provides exceptional heat recovery of up to 99% (thermos 200 dc 97- 99% at 200m³ /h).
Designed to be Inaudible
The high quality balanced fans and attention to detail make PAUL units the quietest on the market. There is no point in building a low energy house if people don't want to live in it. Experience has shown that when constant, even low noise levels prove to be disturbing. Combine PAUL quality with the very best ducting design drawing on years of experience from Germany, the PAUL suppliers are able to provide a service of the very highest standard.
Paul Comfort Ventilation uses high quality large surface area filters that ensure a clean air supply. The large surface area of the filters provides an extended service interval and reduces loss of flow. A properly tuned comfort ventilation system prevents CO2 build up with out the need to open windows. Removing the need to open windows has the added benefit of keeping the noise of contemporary life out side the home.
PAUL Comfort Ventilation units can be fitted in suspended ceilings, horizontally in boxing over kitchen cupboards, vertically in a larder unit, or a utility room or garage. They can supply ventilation demands from 30 to 6000m³/h. The compact units utilise air source heat pump technology to provide both heat and hot water along side the ventilation requirement.
Here is some technical information on the windows we are using Imported from Germany manufactured to the highest standard Passive house certified in Germany. U Value 0.77 metric all the windows and patio doors are the tilt and turn style with a Rosewood foil coating for a wood like finish with out the maintenance and work of staining and painting.

Here is a short Video of the SIP Wall system we will be using on the Exterior Walls for the First and second Floor. 2x8 Wall (7.25")with Foam core R 52 insulation Value with stacked studs no thermo bridging from Studs.
Final decision we received approval for all the Variances subject to Forestry conditions. Wich means the little tree or more specific the little Bush on our Front lawn on the City site is Dim 3,5" more like a weed dousing some trouble and than there is the 3 weeks appeal period before application for building permit more like a nother 2 month before construction.
I am so ready to order the super insulated wall paneles this week from http://www.raycore.com/wall.php
2x8 (7,25")walls Foam core R 7 per inch with offsetting studs. for Main floor and second floor. Wich makes the Main walls R 52 in additions we will have 3" of Foam under the stucco finish adding another R 12 for a total R value R 64.
Windows are leaving Germany on Monday with 3 weeks shipping time should be here by Month end, well there is the wild card with customs wich could delay things a pit. Glazing U Value 0.5 metric with swiss spacers 2 low E films and Gas filled. Frames are Foam filled with triple seals multipoint locking tilt and turn. Geneo Profile the. The cross section shows the recommenced installation detail.
