EkoBuilt Project: Passive House in Etobicoke

We’ve got lots going on this summer across our homebase, the Ottawa region, but we’re also working on a new passive home in the Toronto area. We’re delighted to share a little about that project now.

The home is being built for a young forward thinking family who had to grapple with whether to replace the previous home on their property, which was built in the 1920s. Ultimately, this older home was sacrificing their health with poor indoor air quality and affecting their finances with extremely high heating bills.

EkoBuilt Open House this Saturday

We’ve had tremendous feedback on our Open House at the EkoModel Home this Saturday, 26 January 2019. Paul Kealey is already fully booked for conversations with some of you throughout the day; if you haven’t snagged a time to speak with Paul, don’t worry, there is still much to come out for:

  • 12.30 – 1pm will feature a presentation on sustainable home building by a team from Algonquin College
  • The whole day will be a super opportunity to look over and feel what it’s like to be in a passive home built with care and quality materials
  • If you’re lucky, you may get a few minutes to speak with EkoBuilt’s Paul Kealey, but if not don’t worry, you can follow up with a phone call or arrange a meeting. EkoBuilt will also be an exhibitor at three shows in Ottawa this spring and will run another Open House at the EkoModel Home in April.

Reflecting on a warm winter in the EkoModel Home

The sub-title for this post really should be “how comfortable is a passive house in winter?” And the answer is: very!

Okay, so the sun has been shining and we’re feeling the summer’s warmth, but cast your mind back to the long, grey winter we had here in the Ottawa Valley. Not for long, just long enough to picture the environment in which the EkoModel passive house spent its first winter.

Although the average temperature for the area was roughly -5.5C from December through March, December and January both saw some supremely cold days: -28C the low in December, -25C the low in January. Throughout the period we kept the house at steady 21C for daytime and evening; overnight, with no heating, the temperature would make a gentle fall to 18 or 19C by morning.

Having lived in homes in the past where keeping the temperature at 21C would have been too costly, this round the clock comfort was the revelation we hoped it would be. Both floors of the home, including the upstairs bedrooms, maintained these temperatures – no ‘cool spots’ as in many older homes.

All of this was achieved using an average of just 31.75 kWh per day – which may not seem that low, until you remember that this passive house has NO FURNACE. That hydro-electricity usage simply represents the operation of the ‘solar engine’ components (including a fresh air exchanger, and an air-to-air heating and cooling pump) of the house, and daily living (lights, cooking, heating water*, PC and television usage) of a family of five.

So, our total energy bills for the four deep winter months was $801.48 (or $200/month).

*We heat our water to 120C.

An interesting note on Sunny Days

If it was a sunny day and we had approximately six hours of sun or more pouring through the south facing windows, we did not need to use the heating system at all.

The sun had no problem raising the temperature of the house from 19°C in the morning to about 24°C in the afternoon, in which case the temperature would drop to about 22°C in the evening and hover at about 20°C in the morning. Amazing!

 

What we’ll do differently next year

Overall, the house performed as expected, and the very low energy usage (seen here) and bills, even in a cold, grey winter, are great practical evidence. Less easy to share, but no less significant, is the supreme comfort that we enjoyed all winter long.

Hydry usage for the EkoBuilt passive house in winter 2017

Looking ahead to next year, we’re considering installing an ethanol (biofuel) fireplace. These units are a very simple and clean alternative to wood burning fireplaces and woodstoves, and their benefits are amplified in a passive house, where much less heat input is required to warm the home, and a fresh oxygen supply with good airflow is continually available.

There is a great overview of ethanol fireplaces on Houzz, and again we’d underscore the greater benefit to a passive house over a conventional build. In brief, this heating method has a very small environmental footprint, is low maintenance and attractive. We see this heat source as a great alternative when sunshine is severely limited, as it was this past winter in the Ottawa Valley. Any successful system has a built-in backup, and this looks like a great way to round out the solar engine that is driving our passive house.
