2. Active Living Walls
by Ashley, Veronica, Amy and David
Heating and Cooling outdoor air burns fossil fuels
In the winter, cold fresh air must be heated before it can go into the building, and in the summer it must be cooled. This levelling of the outdoor air temperature to comfortable room temperature is carbon-intensive as well as costly, especially when one considers that the indoor air is refreshed several times per hour. To do this job the building's heating bill and eco-footprint must be enormous.
Thus! Our problem changed from a concern about IAQ to one of reducing the building's eco-footprint.
Active Living Walls: Let's make our own fresh air!


Where is the most effective location for a living wall at OCAD? Right in your face as you walk through the doors! When you look up, there are walls that go up forever right up to the roof. Putting living walls left, right and centre would not get in anybody's way; and if that weren't enough, these walls face windows that bombard them with natural light all day long.

To prove my point, look at how well this little guy is doing!

Cost
Nedlaw told me that the Koffler wall cost about $35K to install. My own quick and rough calculation is that a wall the size of our proposal would be...let us say, several times more than that! Though I imagine it would pay for itself very quickly, the daunting startup cost is why we finally went with Proposal "A", The Green Screen. However...
Opportunity knocks: The Bandwagon is coming!

And when one looks at who is on the advisory committee, who can doubt that green infrastructure is becoming mainstream:
- Brian Denney, CAO, Toronto Regional Conservation Authority (TRCA)
- Marian Fraser, President, Fraser & Company
- Eva Ligeti, Executive Director, Clean Air Partnership
- Peter Love, Chief Conservation Officer, Ontario Power Authority
- Gord Miller, Environmental Commissioner of Ontario
- Ken Ogilvie, Executive Director Emeritus, Pollution Probe
- David O'Brien, President & CEO, Toronto Hydro
- Scott Pegg, Environmental Policy Group, Ontario Ministry of Energy & Infrastructure
- Anastasios (Tas) Venetsanopoulos, VP Research & Innovation, Ryerson University Toronto
- Scott Wylie, President, Wytech Building Envelope Solutions / Chair, GRHC Ontario Chapter
It's a no brainer that our Greenwall Proposal "B" while expensive is not far fetched but is in fact very much in touch with the zeitgeist, and as such, if we proposed this next year funding would be thrown at our living wall from all directions. Then OCAD would be renowned not only for the hip Sharp Centre but also for our Living (and breathing) Wall.
note:
I wasn't going to blog this since our group went with Proposal "A", but doing the presentation this morning put a spur into me blogspot.
