agenda 5.6.15
WHERE do we build? (Monday's class)
HOW do we build? (today's class)
agenda 5.6.15: where
city is inherently greener—because it is denser, resulting in
big transport energy savings, convenience, quality of life
but, density has its downsides too; how can architects and
planners enhance its attractiveness?
parks and recreational features
spaces layered with multiple uses
design in practice: Dilworth Park, Philadelphia
Reworking the transport hub underneath Dilworth Park was a major purpose of
the renovation.
This also provided an opportunity
to create new spaces above ground,
including a lawn and a
waterpark/play space.
With the fountains on, it's a water park for kids.
With them off, it's a meeting place for events, concerts, movies, etc.

where (continued)
huge benefit to be harvested from greener suburbs
improve public transit links to city
encourage walkable, mixed-use near transit hub
encourage smaller homes more densely concentrated near
shared amenities/services to reduce driving
agenda 5.6.15: how
HOW do we build?
infill! stay where it is already dense! [narrow houses]
move less
age in place
live-work
multi-generations, same tax plot
adaptable/growing houses
change construction process
prefabricate some or all of the house
construct more energy-efficient houses
salvage
Passivhaus
produce more energy-efficient landscaping (permaculture,
xeriscaping)
prefab
why?
saves time on site
can increase environmental quality

Passivhaus
• good levels of insulation with minimal thermal bridges
• passive solar gains and internal heat sources
• excellent level of airtightness
• good indoor air quality, provided by a whole house
mechanical ventilation system with highly efficient heat

I hope you'll tell
me all the wonderful
things you are doing
in architecture
and in life!
The Manhattanization
of TorontoIgnore the hand-wringing. Forget the predictions of doom
and gloom. The Manhattanization of Toronto will be best
thing to happen to this city.
Though the term has come to mean little more than a vertical
city crammed with towers, there’s more to it than that.
Toronto certainly stands tall; more highrise buildings are
under construction here than any other city in North America,
including New York. This week alone, city council approved
more than $20 billion in new development, the bulk of it
highrise.

What makes Manhattan unique, however, is not the number
of skyscrapers or their height; it’s that city’s passionate
embrace of density.
That’s where Toronto has trouble. Though some believe the
city has evolved too quickly, market and demographic forces
won’t be controlled, and can’t be contained. People now want
to live and work downtown. The condo allows them to fulfil
that dream.
Christopher HUME, "It’s time Toronto got smart about being dense,"
Toronto Star 29 Aug 2014

In Toronto, chief planner Jennifer Keesmaat worries that the
municipal infrastructure can’t keep up with the pace of
development. She’s right. This isn’t to say that growth should
be slowed, but that development should be smarter and, just
as important, that we need to make better use of the existing
infrastructure. To begin with, builders must pay a greater
share of infrastructure costs. To ensure the continuation of
civic services that make their condos so desirable, higher
development charges must be levied. Few builders would
agree, of course, but ultimately it’s in their own best interests
to contribute to the well-being of the city that has made them
rich.

Beyond that, the industry and policy-setters must shift the
focus from small investor-friendly units to decently sized
apartments where people — including families — can make
a life. There is resistance to the idea from buyers as well as
developers. The cause is the lingering bias in favour of
single-family housing. But already families are moving in their
hundreds to condo towers, knocking down walls and
reconfiguring units to make them suitable for kids. As the
supply of affordable houses dries up, this prejudice will
disappear, as it has in other big cities.

In addition, we need to hold another of those grown-up
conversations we’ve promised ourselves — this one about
how best to deploy systems already in place. For example, is
leaving roads to cars and trucks really the best use of the
precious spaces of the public realm? When David Mirvish
proposed his twin-towered condo complex for King and John,
the city’s response was to complain it was “too dense.” Too
dense for whom? Cyclists? Pedestrians? Transit riders?
Drivers?

embodied energy
the sum of all the energy needed to produce an item,
represented as if that energy were incorporated or
'embodied' in the product itself.
Architects work on a scale where individual choices have an outsize impact: for positive
or for negative
