Comment: Current NBC - Alberta version 2023 allows the addition of a 25mm nosing to 355mm maximum run in Private. (NBC 9.8.4.2 sentence 2). Therefore the maximum tread depth is 380mm. This was correctly demonstrated in version 22 of this module 020204aA on page 6. But somehow it got changed back to the old code. This impacts the code review in this 4th year module where it states in the chart that the maximum tread depth is 355. The maximum tread depth should be 380mm.

Figure 33 would also need to be updated. - Self Test question 23 answer would need to be updated to reflect change. Page 43 - Figure 38 needs updating on dimensions and pictures to align with building code - Self Test question 28 will need updating based on changes Multiple images in module could use updating, not sure anyone has a tube T.V. anymore.

Comment: The bullet points need a rework. These are the principles of Passive House from the Passivhaus Institut reordered to match the module: ******************** Thermal insulation All opaque building components of the exterior envelope of the house must be very well-insulated. For most cool-termperate climates, this means a heat transfer coefficient (U-value) of 0.15 W/(m²K) at the most, i.e. a maximum of 0.15 watts per degree of temperature difference and per square metre of exterior surface are lost. Airtightness of the building Uncontrolled leakage through gaps must be smaller than 0.6 of the total house volume per hour during a pressure test at 50 Pascal (both pressurised and depressurised). Absence of thermal bridges All edges, corners, connections and penetrations must be planned and executed with great care, so that thermal bridges can be avoided. Thermal bridges which cannot be avoided must be minimised as far as possible. Passive House windows The window frames must be well insulated and fitted with low-e glazings filled with argon or krypton to prevent heat transfer. For most cool-termperate climates, this means a U-value of 0.80 W/(m²K) or less, with g-values around 50% (g-value= total solar transmittance, proportion of the solar energy available for the room). Ventilation heat recovery Efficient heat recovery ventilation is key, allowing for a good indoor air quality and saving energy. In Passive House, at least 75% of the heat from the exhaust air is transferred to the fresh air again by means of a heat exchanger. ************************ *My Comments* "The Space Heating Energy Demand is not to exceed 15 kWh per square meter of net living space (treated floor area) per year or 10 W per square meter peak demand." (https://passiv.de/en/02_informations/02_passive-house-requirements/02_passive-house-requirements.htm) Airtightness: A maximum of 0.6 ACH at 50 Pa. Thermal bridging is to be eliminated or minimized where elimination is not possible. Whereas high quality windows must be used and even Passive House certified windows are preferred there is no mention of orientation in the overall principles of Passive House. It would be hard to make it happen without good orientation though.

Comment: Figure 27 has a problem. The doubled header at the top doesn't work out well with those stub rafters coming into it. The top of the stub rafters for sure would not line up with the header top when the header is plumb and not perpendicular to the rafter. I suggest that the headers be placed perpendicular to the rafters.

Comment: The process on this page only works for unequal slope roofs where unequal height or projection of the soffits is NOT an issue. On the following pages the process is described for equal projection/consistent soffit height. There should be a statement to that effect on page 18 to make it more clear that it works only when soffit height/projection consistency is not necessary. I often have students confused by that description and image when we build an unequal slope rafter project in shop.

Comment: A better method for dent repair put forth by Bob Flexner is to use an eyedropper to put drops of water onto the dent and then allow that to soak in, and then use a damp cloth to heat the dent only and as little of the surrounding area as possible thereby reducing damage to the surrounding area.

Comment: The graphic showing the minimum height to combustibles should show 600mm to the combustible when the combustible is protected by a range hood or other non-combustible protection. The dimension line is the problem and the number to a lesser extent. Perhaps two separate graphics would help. 9.10.22.2. Vertical Clearances above Cooktops 1) Except as provided in Sentence (2), framing, finishes and cabinetry installed directly above the location of the cooktop shall be not less than 750 mm above the level of cooktop burners or elements. 2) The vertical clearance described in Sentence (1) for framing, finishes and cabinets located directly above the location of the cooktop may be reduced to 600 mm above the level of the elements or burners, provided the framing, finishes and cabinets a) are noncombustible, or b) are protected by a metal hood that projects 125 mm beyond the framing, finishes and cabinets.

Comment: In the New Curved Stair module 020202d on page 28, it calculates the inside unit run as 314.2mm. Top of page 29 in a note, it stats; “In this example, because the inside unit run is already more than the minimum unit run (255mm) required at the walking line, you do not need to calculate the walk line unit run.” When you do check the walk line unit run it exceeds the maximum of 355mm. If this were public stairs it would be fine but the note would have to say (280mm) for public minimum.

Turn/360 = Partial Circle/Full Circle This same ratio set up can be used for calculations on page 19 where we’re given another set up and then again on page 32 where the students are presented a third set up where the ratio is flipped over for the same calculation. Consistently would help keep things clear for the students.

Comment: In the New Winder Stairs module 020402c, version 22. Page 9 has a walk line radius calculated at 487mm and the note below it stats “Since the walk line is always considered to be 450 from the inside of the stair, the layout point for the winder nosings cannot be less than 450. Therefore the walk line radius = 450 With the new minimum unit run code of 255mm, a calculation that is less than 450 is no longer possible and these notes can now be deleted.

Comment: In the New Winder Stairs module 020402c, version 22. Page 8 has a walk line radius calculated as 506.11. This is rounded up to 507. On page 9 a walk line radius is calculated at 487.013 this one is rounded down. Page 10 Walk line radius is calculated as 534.76 and it’s rounded up. Examples continue throughout the module. Previously these values were always rounded up. We either need to use basic rounding rules or have a standard.
