When I was in grad school, I used to search around online and make lists of real estate developers that I felt were philosophically aligned with my own view of the world. I didn’t want to work for just any developer, I wanted one that cared about design, technology, sustainability, and so on.

One of the developers on my list was OVG Real Estate in Amsterdam. They describe themselves as “the largest real estate technology company in The Netherlands” and they have recently completed The Edge, which is being called the greenest office building in the world. It received a 98.36% sustainability score from BREEAM-NL.

The building uses 70% less electricity than the “typical office building” and uses solar panels on its rooftop, as well as on some neighboring university buildings, to produce more energy than it consumes. The building is also a great example of the Internet of Things. Anchor tenant Deloitte created its own mobile app so that employees can control lighting, climate, and so on.

The building also has an on-site gym. I’m a big fan of mid-day workouts.

There’s a lot going on with this building, so here’s a video from Bloomberg describing how it functions (click here if you can’t see it below):

This evening I had a fascinating conversation with Subhi Alsayed of Tower Labs. If you haven’t yet heard of Tower Labs, I would encourage you to check them out. Here’s their mission statement:

Our mission is to facilitate the adoption of green building products, technologies and practices through pilot and demonstration projects in highrise buildings; and accelerate the evolution to a low-impact, sustainable urban environment.

What they do is test out new green building technologies in one-off condominium suites. And since they were founded by both MaRS and Tridel (which is one of, if not the largest condo developer in Toronto), they have plenty of opportunities to do just that.

This is important because the real estate industry is notoriously slow at innovating. I’ve written about this many times before. Whenever you try and introduce something new, there’s always a lot of change management that goes along with it. The construction trades, to use one example, need to get their heads around it. And until they do, they’re going to charge a premium for it.

So by creating a one-off test case, everybody gets to see how it works, how it is built, and, most importantly, how it actually performs in the real world.

One of the projects that they’re working on is something called NetZED, which stands for Net Zero Energy Dwelling. As the name suggests, it’s a condominium suite that produces as much energy as it consumes. 

The way it works is by trading energy. At night when the sun isn’t out and the panels on the roof aren’t able to produce energy, the suite “borrows” electricity from the building. But during the day when the sun is out, the suite powers itself and then returns any borrowed electricity to the building. Click here to learn more about the suite. It’s being built in the Aqualina Condos on Toronto’s waterfront.

I find all of this incredibly exciting. Not only because they’re working towards a more sustainable future, but also because they’re applying their efforts towards the multi-family building typology (towers). Given that most of the world now lives in cities, this is an important building typology to make even more sustainable.

“We can’t address climate change without thinking about buildings.” -Bryn Davidson, Lanefab (Vancouver)

This is a line from a recent TEDx talk by Bryn Davidson, who is one of the founders of Lanefab out of Vancouver. Lanefab is a design and construction firm specializing in sustainable infill / laneway homes. Unlike Toronto, laneway houses are actually allowed in Vancouver.

If you have any interest in climate change, I would encourage you to watch his talk. It’s less than 20 minutes long and he addresses many of the misconceptions that I think people hold about what it means to build “green”. Click here if you can’t see it below.

While I think it’s great that the green agenda is much more front and center these days, I agree with Bryn in that we’re not yet on a sustainable path forward. For many people, being green means buying a LEED certified home, having a Tesla in the garage, and having a Nest thermostat on your wall. And certainly those things help.

But they’re not the whole story. Instead of just focusing on green and LEED buildings, Byrn argues that we need to take it a step further and start focusing on “Net Positive” buildings. In other words, ask yourself this: Will there be fewer green house gas emissions on the planet after your project is built?

More specifically, he outlines 3 criteria:

1. How good is your building?

2. Where is it located?

3. What does it replace?

The idea behind this framework is that the building itself (i.e. How good is your building?) is only one piece of the story. What also matters is its location and what it happens to be replacing. Is the building in a walkable area? Is it on a greenfield or infill site? Is it replacing an old energy inefficient building? Is it intensifying land use patterns?

All of these things matter when it comes to assessing our greenhouse gas emissions.

Let’s now apply this framework to three different building typologies: mid and high rise condominiums, and laneway houses. In the context of a Net Positive building, they all do quite well. In Toronto, we could certainly do a lot to improve the way many of our condo buildings are built, but they are usually in the right kinds of areas and they are the right kind of building typology.

Similarly, laneway houses as a whole are an incredibly sustainable building typology. In fact, I would argue that an energy efficient laneway house is easily one of the most sustainable homes you could build. They’re compact. They’re located on under-utilized and previously developed land. They often replace parking. And they increase population densities in established residential areas, which then makes transit more feasible.

But again, here in Toronto we’re not allowed to build them.

So whether you like it or not, if you’re involved in shaping the built environment, you’re also involved in climate change. This is a job for architects and developers, but also policy makers and communities. Laneway housing is a perfect example of that. Lots of people would build them — if only they could.
