Update - Upcoming house tours

***UPDATE*** Due to the extreme cold forecast for Saturday Feb. 13th we have decided to postpone the tour scheduled for that date. Wind chill is expected to be -32 and we don't have insulation in yet! Still planning to offer the tour scheduled for Sunday Feb. 21st, so please sign up for then.

 —

Mark has offered to give tours of our place over the next couple weeks. If you're a Passive House junkie, architecture-enthusiast, nosey neighbour or just plain curious, come on out. We're happy and excited to show it off. The house is in Hintonburg, a neighbourhood in downtown Ottawa.

Please sign-up using this form.

If you can't make either of the first dates, have no fear – if there's good interest, we will continue to conduct them periodically throughout the build. Just make sure to sign-up on the form to let us know you're interested. And we'll email out the dates so you won't miss out.

Construction week 23: roof trusses

Mark did a pretty great job explaining the roof truss install, which happened this past Tuesday. Thanks to Mark Greenacre for helping out the team. With the remaining days, they built additional frame walls to support the trusses and added the cross bracing to keep it square.

This upcoming week, they'll be finishing the roof prep and installing the roof sheathing. The roofers are due to arrive Wednesday! We are going with a black/grey metal roof, which will be seen by no one.

I had a couple concerns with the metal roof at first:

1. Would it attract lightening bolts?
2. And would the dark colour add to the cities 'heat island effect'?

I'm glad to report, through diligent googly research, that I need not be worried, in either case.

If you're flying your drone overhead, our roof will look something like this:

Yesterday was a big day. It started bright an early with the crane set-up on site. It was there to haul up and help install our roof trusses. Mark was in and out throughout the day and broadcast a few times with progress updates. Here they are:

Construction week 22: wall framing complete

The girls are happy (and toasty) in these walls.

At long last, our house has been framed in. (We still need a roof over our heads — a minor matter.) It feels good to have that massive task behind us. Our builders are, no doubt, also quite happy about this.

Our walls were no ordinary walls; they were an experiment/idea Mark had as to what they needed to be and how they needed to come together. This wall phase took a couple weeks longer than anticipated by Mark. There were bumps along the road, and a definite learning curve, but the team hit their groove, in spite of the bone-chilling temps, and put together one helluva house shell. We were fortunate to have such an open-minded and capable team, headed by Justin at Cornelis Grey.

We've rented a crane, for this coming Tues, to lift our roof trusses up so the roof can get going this week. Yay! And we're starting to line up tasks to follow. Windows, insulation, siding... Not to mention a whole slew of decisions requiring our attention, e.g. cabinetry, fixtures, flooring... There's no shortage of things to do.

And here are some shots of the shell from today.

What's keeping Mark up at night

A cold house and throwing our heat/money outside. Whadda waste.

We are currently renting a home from some (wonderful) neighbours. It's an older home, a townhouse. And they've done many things to improve it over the years. However, Mark's been noting the depressing frequency with which our furnace turns on. His last count clocked it at 8 minutes. Which is to say that in 8 minutes, our house is losing one degree of heat to the great outdoors. If the furnace conked out and we lost a heat source, for whatever reason, our house would reach the outdoor temp, let's say a balmy -8° C for this scenario, in just under 4 hours. Half way through sleep. A couple hours and it's inhabitable. I find this shocking.

Construction week 20: 3rd floor framing

There's snow in the house. We always liked the idea of bringing the outside - in. But this is taking it too far. Wah-wah.

Our second floor (third if you include the walk-out basement) has been framed in. The cold temps have definitely come with challenges. We're using an adhesive on the edges of the wood fibre board that needs to be warm to be malleable. So we've rented space heaters to keep a small section of the basement warm for the adhesives. And there's snow on everything.

It's so bloody cold. Went out there for half an hour last week and my toes almost fell off. Props to construction workers in this city. It's unreal. And then I go sit in my cushy, warm office job, feeling slightly unworthy. Respect.

We took some friends on a tour of the house this past weekend. They had their children with them. The five year old said, "Mina's house looks like Elsa's* castle because it's tall and there was snow inside".

* For those of you who don't have a child, Elsa is a snow queen from Disney's film Frozen.

The third floor joists should be going in this week. In the meantime, Mark and I are trying to work out some design details for the inside, of which there are many. He's working on our kitchen & bath layouts so we can get them priced out to make decisions. We're agreeing on all the big picture items, so hopefully that bodes well for when we have to start selecting finishes.

He's also working on our HRV design. Where the fresh air and exhaust vents will be located. It's fascinating stuff. I'm working on a post with fancy visuals to help illustrate the concepts. I'm also doing a bit of research in to automated home technologies – ways to make the house smart. If anyone has any knowledge in this, please share! Just because the house is low-tech (crudely-speaking), doesn't mean other areas of the house have to be. Lights that learn? Maybe.

A(nother) Passive House blog

Need more convincing? Check out BLEUnest's website. The writing is pretty hilarious. And with great PassiveHouse information, in layman terms. Who doesn't love a good infographic? (Answer: no one). I particularly enjoyed this recent post. http://www.bleunest.com/make-average-your-enemy

Passive House vs. traditional build. Conservative with their 4% annual energy cost increase. Numbers are pretty 'ballpark', but gives a sense of how the numbers will even out...eventually.

Roxul arrives!

A cozy blanket for our Passive House

Today we took delivery of 144 bags of Roxul mineral wool insulation, which is just over half of the 246 bags we ordered. They are stacked high and tight in the basement and it won't be long now until we warm up those truss walls with 4 layers of these batts! 

Second floor is coming together quickly now.
