Its been a very long time since I lived in Montreal, but I don't recall any government at the arrondissement level. How do they set and enforce rules?

The arrondissements adopt their own urbanism plans that become chapters into Montréal's, while having to be consistent with the major planning principles and guidelines contained in the Montréal masterplan.

They have since the municipal merger of 2002. They didn't before then. Well, I don't think Montreal actually had arrondissements before then.

Arrondissements have mayors and councils even.

Why the white roofs?

[WhipperSnapper]

White roofs are the new standard for some time. It's more energy efficient. The colour doesn't absorb heat.

Most jurisdictions are calling for this now.

Reflects sunlight instead of absorbing it, reduces urban heat gain.

We could use a little urban heat gain about now - why is it a bad thing ?

We're a cold weather country. I could see wanting white roof for 4 months of the year, but wouldn't passive heating be a good thing for the remainder of the year.

The roofs aren't covered in snow for 8 months out of the year.

It costs less and less energy intensive to heat a building than it is to cool, generally speaking. Roofing membrane will have an insulation layer underneath it (inverted roofing) so you don't really get any thermal gain from a roof. Not any you want, anyways. Plus roofing material will last longer if it's not heating up as much so light colour roofing is preferable for the most part

[WhipperSnapper]

Snow is also a modest insulator. Snow on the roof is better than no snow on the roof and ice in and around the property. IRCC, the white roofs tested even better for our cold winter than traditional black.

[Marshal]

White roofing is more about climate change than heating/cooling issues. It's about reflecting solar energy before solar gain (heating) even comes into play. This phenomena operates all year long, though winter sun angles make it less at that time of year. As such, it's a large scale thing (city wide) rather than an individual building concern.

[niwell]

In places like Montreal and Southern Ontario, white/cool roofs (and green roofs for larger buildings) can significantly reduce the urban heat island effect. This is much more of a concern than any passive heating you could achieve during winter, which in itself would be minimal for a properly insulated building.

I know Toronto does so would assume Montreal has incentives for installing such roofs. Green roofs are the ideal but they aren't suitable for many buildings both due to cost and structural issues.

[harls]

It's kind of crazy the tangent I created. I seriously thought there was a layer of snow on those roofs.

Now I know.

Holy **** Vancouver.

That skyline is just begging for something 250m+ though.

[Vixx]

Yeah if Vancouver had at least 1 250m+ tower it would take it to another level. It is great as is, but dammit the tabletop effect has to be broken lol
