  • Brockton Village 2 is our next super-efficient rental triplex in Toronto. It has three two-bedroom units, and it’s our most air-tight project yet.

  • Same Great Neighbourhood

    Continuing the theme of energy efficient conversion projects, Brockton Village 2 started out as a single-family home that hadn’t been touched in decades. Its location, size, and great bones made it a clear winner for our next Eco Flats project. It has immediate access to the Dufferin bus and the Dundas and Queen streetcar lines, and the Dufferin subway and Exhibition GO stations are just a twenty-minute walk away.

    In the neighbourhood are plenty of great cafes, restaurants. Just around the corner is Mary McCormick park and community centre with skating rink, playground, and summertime wading pool. An extra bonus is that it’s easy walking distance from Brockton Village 1. We couldn’t pass up this property!

  • We decided to keep to the existing building size of this semi-detached house. We used the two storeys plus basement to create three distinct apartments, one on each level. Each unit has two bedrooms, one washroom, open-concept kitchen/living/dining, ample storage, in-suite laundry, and a mechanical closet containing its own HVAC systems.

    This building, like Brockton Village 1, does not have on-site parking. It does, however, have a spacious backyard with a walk-out from the main floor apartment, and we created a patio off the upper-level apartment.  Each unit has its own private entrance: the lower level enters through a sizeable walk-out from the front; the main floor unit’s “front” door is at the back; and the upper unit uses the original front entrance of the house.

    This project is also completely electric. Since the renovation is so energy efficient, well insulated, and airtight, electricity consumption for heating and cooling will be minimal. And when we say air-tight, we mean the most air-tight building envelope we’ve ever done! (Sneak peak to the Envelope post: Brockton Village 2 achieved 0.34 ACH!)

    Another great feature of this triplex is that each unit has its own controls for heating and cooling. Our tenants will be able to make their individual apartments suit their own comfort needs!

    We’re thrilled to share this latest Eco Flats project with you. Up next, we’ll talk about the floor plans and design of this super-efficient, all-electric rental conversion.

Entrances

The first interesting thing we’ve done here is with the entrances. For Brockton Village 2, we really wanted to create suites with their own private and unique entrances. The lower level has a spacious entrance at the front of the house, with a wide staircase leading down to a large landing area with a glass-panel front door. The main floor unit has it’s “front door” at the back of the house with access down the side and through the backyard. The upper apartment uses the traditional front door on the Dufferin Street porch, which opens onto a staircase that leads straight up to the upper Living/Kitchen/Dining area.

The entrance configurations determined, in part, how the spaces are arranged in each unit. For the top two units, the living spaces are at the back where their main entrances open on to. They also each face out to their own private outdoor space at the back of the house: the backyard for the main floor and a rear deck for the upper unit. Since the lower level opens directly into the front of the floor plan, it’s living/kitchen/dining area is at the front facing Dufferin Street, with the bedrooms located at the back.

Each unit’s layout also includes an open-concept living/kitchen/dining area, full washroom with large bathtub, private in-suite laundry, lots of closet space, and a dedicated mechanical room with its own individual HVAC controls. The ability to have fully independent heating and cooling controls was very important to us, but more on that in the Systems post.

Fitting into Context

For this project we really wanted to fit in with the surrounding properties, and particularly to match the next door semi-attached house, even if that meant keeping the white aluminum railings. White aluminum railings might not be what many people expect from a newly renovated project, but even though they might not be our first choice from an aesthetic point of view, we didn’t want to send material to the dump without a very practical reason. And the money we saved by keeping the existing railings allowed us to spend more on landscaping at the end of the project, which the neighbours and tenants really appreciate! We also went to great lengths to keep the front porch ceiling and porch light in order to match the neighbour, and we think it presents a nice and consistent feeling when you see it from the sidewalk.

Each two-bedroom unit has its own unique layout, and its own private feel. The house is built with sound-attenuation between the units, keeping up the feeling of privacy for everyone. Luxury and privacy in the city aren’t always easy to find, and we wanted to provide that for our tenants. We also hope there will be a nice social atmosphere between them as well, perhaps aided by the fact that they all have their own spaces. At Brockton Village 2, our tenants are not “on top of each other”, even through they’re stacked on top of each other.

Private, Bright And Resourceful: The Structure At Brockton Village 2

  • A lot of thought and strategy went into turning the original building into three beautiful rental apartments. We tried to use as much of the original building as we could, and to work around existing openings and roof lines. We think we did a great job with this one.

    Brockton Village 2 has three 8-foot-high levels with large windows on three sides. We always want our basement apartments to have high ceilings and to let in as much light as possible. The great thing about this property is that the house was already quite high out of the ground. We didn’t have to dig window wells on the outside and we still got huge windows in the lower level.

    While the window heights off the ground were there, the basement floor-to-ceiling height was only 6’-6” in the original building, so the first thing we did was to underpin and lower the floor. To do so we had to take out the existing beams and put in new ones. We also installed new posts and footings. Our neighbour in the attached house was very supportive, and happy that we were underpinning his house while we were at it.

    The existing basement had a huge steel beam going through it, which we didn’t need. It was awkwardly dropped below the joists and in a position that didn’t work with our design. We removed the steel beam and replaced it with a new Laminate Veneer Lumber (LVL) beam. The span required in this case can definitely be done with wood, and we think that whenever you can do something in wood, you probably should. We want to do what we can support an ethical and sustainable forestry industry. Removing the original beam wasn’t easy though. We had to build two walls to support the floor above before we could remove it, then cut out all the joists, lower the beam, take out the columns that were supporting it, drop the beam, and then carry it out.

    Upstairs, the existing flat roof at the rear was only a few years old, so we left the roofing on and only reframed and reinforced it with new wood underneath. We then filled it with closed-cell spray-foam insulation because that was the only way to properly insulate it. More on that in the envelope post.

    Each two-bedroom unit has its own unique layout, and its own private feel. The house is built with sound-attenuation between the units, keeping up the feeling of privacy for everyone. Luxury and privacy in the city aren’t always easy to find, and we wanted to provide that for our tenants. We also hope there will be a nice social atmosphere between them as well, perhaps aided by the fact that they all have their own spaces. At Brockton Village 2, our tenants are not “on top of each other”, even through they’re stacked on top of each other.

  • We wanted our tenants to enjoy as much peace and quiet as possible, so sound attenuation between the units was very important to us. Between the units we’ve put a layer of 5/8th-inch plywood on top of the floor structure, which adds more solidity. Below that is a layer of 3-inch mineral wool with resilient channel (metal tracks) underneath, and sitting on those is 5/8th-inch drywall. It’s a standard 45-minute rating between units, but it also gives you very good sound attenuation. The fire separation has to be continuous, so the drywall goes right to the walls. There’s quite a bit of planning and coordination to do this and get the ducts through to where they’re needed.

    Stairs are a place where you often hear a lot of noise in rental buildings. We put in a brand-new, well-built staircase and took a lot of care to secure it firmly to the wall to prevent any creaking and squeaking. We even went so far as to bolt it into the wall with epoxy anchors. It’s easy enough to do, but it’s atypical. We’re proud of our silent staircase.

  • While we tried to use as many of the existing window openings as we could, there was still a fair amount of masonry work in this renovation. We used as much existing brick and concrete block as we could from the original house itself. For example, there was a concrete block wall in the rear of the basement that we didn’t need, so we were able to salvage those blocks and use them elsewhere in the building.

    The steel beam that we removed from the basement was a concern, as we really didn’t want it to go to the scrap yard. We tried so hard to reuse it on site, but in the end we simply couldn’t. After lots of searching, we eventually found someone who wanted to turn it into a gate. Problem solved.

    So, there you have it. The structure of Brockton Village 2 prioritizes light, privacy and quiet for our tenants. Next we’ll talk about the building envelope and how air-tight this building is.

Seal it Tight

Brockton Village 2 is extremely well insulated, and it’s one of our most air-tight renovation building envelopes. The existing building started with a leakage rate of 10 ACH before construction. After construction that number dropped to 0.34 ACH – a major success! Once the ducts were installed, the ACH did go up a bit to about 0.6 due to some unavoidable leaks in the intake and exhaust ducts. However, we still met the Passive House requirement for newly built homes – in a reno no less – and we are very proud of this achievement.

The secret to our success is not just one magic product – it’s a combination of diligence and ingenuity, coupled with some great products and technologies. We worked everything out in advance to create a system for air sealing the building. First, we thoroughly inspected the whole building and identified challenging areas. These are typically areas where two planes intersect, like floor and wall, and tight, hard to reach corners.  Then, we targeted those areas first using air barrier tapes, parging, acoustic sealant and, in larger areas, a first pass of spray foam. We then had a blower door test done, which we followed up with a second pass around the aforementioned tricky spots. But wait, there’s more: we did another blower door test, then did the balance of the spray foam, then did a fourth blower door test, and THEN applied AeroBarrier, which pushed the airtightness down even further at that point from 1ACH to 0.34ACH.

Now let’s talk about AeroBarrier. It’s a fairly new technology, and we are very happy with its results. It’s a product and a system, all in one. The product is a water-based, non-toxic sealant, and the system is the way in which it’s applied: the sealant gets “misted” through a special spray system inside a building pressurized to 100 Pa. Like a dense fog, the atomized caulking floats around and gets sucked into even the tiniest of holes in the envelope. As it passes through the hole, it coagulates and blocks the hole completely. It’s so effective that it will even seal holes that are as large as half an inch in diameter. After 20 minutes, any of the product that hasn’t been utilized, harmlessly falls to the ground where it gets swept up.

For Brockton Village 2, we used AeroBarrier before insulation and drywall were installed. In this way, we were able to plug all tiny pinholes that result from slight imperfections in the envelope, doing more than we could do by hand.

Unit-Controlled All Electric Systems At Brockton Village 2

Brockton Village 2 is an all-electric triplex, and each unit has full control over the comfort of their own suite! Have you ever rented an apartment and had full control over the heating and cooling in your unit? We’re guessing most people would answer “no”. For all Eco Flats buildings, we prioritize individual unit controls for heating, cooling, ventilation, and humidity.

Why all-electric? Well, it produces less carbon than natural gas. Electric systems might cost more to operate than gas-powered ones, but it’s virtually carbon neutral, and it’s worth it to us to pay that extra bit of money for lower carbon output. Besides, our buildings are so well insulated and airtight that the heating and cooling loads are way smaller than in most buildings. We figure that paying a higher upfront cost for way less consumption is not only worth it, but potentially even more cost effective in the long term. If you think that’s an iffy bet, we pay for the utility costs for the whole building, so we are not passing that bet on to our tenants. So far so good, too. Our electricity bills for Brockton Village 2 are working out to average over the year at about $36 per occupant per month (or 260 kWh) – and that’s for everything that requires power in the building, all regulatory charges, and delivery.

So, what are these super cool all-electric systems with individual controls? Each apartment is equipped with its own Conditioning Energy Recovery Ventilator (CERV) by Minotair, a Canadian company based in Quebec. The Minotair units are small, each fitting comfortably above the laundry equipment inside a closet. It brings in fresh, cold air from outside through ducts, and then it uses an interior heat pump – all in one small box! Plus, there’s no condenser on the outside of the building like with typical air conditioners. The condenser is on the inside because it’s bringing the outside are in with great volume. It also gets the inside air out, just as well – i.e. ventilation.

The electricity required to heat and cool the apartments in this building is small, because the building envelope is so efficient, and everything in the space contributes to the heating load: the people, the stove, the lights, computers, etc. All these things make the work of the CERV quite easy. And with each unit equipped with its own Minotair, each of our tenants can decide what heating or cooling they need, and when. One unit can be calling for heating and another can be calling for cooling, at exactly the same time.

The hot water tank here uses an air source heat pump on the outside of the building, and because of the Minotair units, it’s the ONLY condenser on the building. It’s a bit pricey for a single piece of equipment, but it serves the hot water needs of the entire triplex. We have the same size tank at Brockton Village 1, our other all-electric triplex, and we’ve had zero complaints about the hot water supply – all without relying on natural gas. Another great thing about this hot water tank is that it can be tucked away in one spot under the stairs. A regular hot water tank is much less efficient and would cost a lot more to operate. Natural gas might cost less to burn, but it won’t be more efficient. This heat pump tank uses about 3-5 times less electricity because of the heat pump effect. While going all-electric can have a price tag, we think it’s worth it in the long run.

At Brockton Village 2, all-electric and great technological inventions means fewer pieces of equipment, more individual controls, and efficient comfort for our tenants. There’s even a greywater system that collects drain water from the baths/showers and uses it to flush the toilets. nd as in all our buildings, there’s a rough-in for photovoltaic panels.

Light, Bright, And Spacious

We want people to feel at home in Brockton Village 2. That’s why we aimed for a light, bright and spacious feeling.

Walls and cabinets are all a beautiful crisp white using Benjamin Moore’s Chantilly Lace colour. Floors in the main spaces and bedrooms are bleached wood laminate. And the tiled floors of the bathrooms and entrances are a contemporary charcoal grey from Olympia. Laminate counters from Ikea that look like butcher block in the kitchen and walnut vanities in the bathrooms add warmth.

We want people who walk into these flats to immediately feel more relaxed (“it’s so orderly!”) and more uplifted (“it’s so clean and beautiful!”). Kind of like a cross between walking into an art gallery and walking into a boutique hotel room.

IT’S A FULL HOUSE!

POP the Champagne! The last of the moving trucks has pulled away and the last of moving boxes have been stacked up at the curb for the recycling truck. Brockton Village 2 is fully occupied, and the tenants are thrilled with their new homes.

FROM BEAST TO BEAUTY

It took a little over a year, but we are so proud to have transformed this dilapidated, leaky old building into an über-energy efficient triplex. Each two-bedroom unit is stylish and spacious. With thoughtful design choices, we’ve brought in all kinds of elements that enhance tenants’ quality of life every day – like soundproofing, the privacy of a separate entrance, a washer and dryer in every unit, and the peace of mind of having utilities included in the rent.

THE POWER OF THOUGHTFUL DESIGN

Our units may have a smaller square footage than some apartments. But thanks to our eye for intelligent design and our extensive experience with residential architecture, we do a whole LOT more with only a little less.
