We’re excited about this one! Mark your calendars for Saturday, October 2nd, 2021 at Lansdowne Park in Ottawa.Read More
The federal government recently launched its Canada Greener Homes Grant. In brief, the grant provides various incentive options for existing homes to upgrade their energy efficiency, however no grants are available for new homes, even though housing starts in many parts of the country continue to grow (in our own local area, new builds are huge in a hot real estate market). In this article, we ask why the government won’t also support homeowners in building highly energy efficient homes right out of the gate.Read More
When we talk about ‘smart homes’, there is a general bias towards technology. Consider this definition:
Standard smart home definition: noun “a home equipped with lighting, heating, and electronic devices that can be controlled remotely by phone or computer.”
At EkoBuilt, we see the smartness in homes very differently, using a sustainability lens.
EkoBuilt smart home definition: noun “a home designed to be autonomous without the use of electronic devices for heating or ventilation control.”
We also think the smartest homes can be affordably net-zero, taking their energy from renewable energy sources. Truly there is much confusion over what a smart home really is. Conventional thinking holds that a ‘smart home’ is one that uses more technology for control. But is that really very smart?
Shouldn’t a truly smart home need less technology?
We feel that a smart home is one that uses the least technology possible. It’s possible to design homes that don’t require all kinds of devices for control.
For example, a home should not need to be heated when the occupants are not there, and blinds should not be required because unwanted heat needs to be kept out. In a true passive house excess technology is not required because the space requires little heating or air-conditioning to be comfortable.
Using energy from the sun as a heat source, the home can be heated naturally even in extremely cold conditions. To reduce the need for air conditioning in hot summers, windows are strategically located to naturally shade themselves so unwanted heat is not coming into the home. This is a smart home!
It is more sustainable, and much smarter to use less technology, both environmentally and physically. There is simply no need to have a wi-fi thermostat. Why spend money to operate a furnace in an occupied or unoccupied home when you don’t have to? It is smart to spend as little money and to acquire as few devices for your home as possible.
Why passive homes are the smartest homes
Our point is of course, to communicate the intelligence of building to the passive house standard. It is, after all, the only truly resilient home known to man.
It is a home that uses so little fuel to heat and cool the space that the electric bills are approximately the same amount every month of the year, whether the home is being heated or not.
Not to be coy, every house, even a passive house, requires a heating system – especially in this part of Canada – but the passive house leaks so little heat (even during extreme cold conditions) that it costs very little to keep the space heated. Less energy, in fact, than a refrigerator uses in a year. Now, that’s a smart home.
Ever compared your home to a thermos?
A passive house is as close as you can get to living in a thermos! The key difference is the passive space has constant access to fresh air, while a thermos does not.
Seriously though – a good thermos can keep keep tea extremely hot for 24 hours, which is really quite unbelievable when you think about it. Well, a passive house is basically the same thing in a home. And that really is a smart home.
From a health perspective, it’s much safer to live in an environment virtually free of interior toxins or exterior pollution (propane or gas emissions), full of ample fresh air, and designed to last generations. Again, that’s a smart home.
Another vital feature of a truly smart home is that it be electrically operated. We’ve come to the point where a home designed to operate by propane and/or gas, is a home designed for the past. Fossil fuels are not the way forward. Homes for today and tomorrow need to be 100% electrically operated — it’s simply the only fuel source for sustainability. It’s also the best for our health and for our pocketbooks.
A home that helps to create a healthier environment is a home that is healthier for us, and energy savings translate into lower operating costs, and that means more money in our pockets.
In conclusion, a truly smart home designed for today should be one that is built to passive house standards. Realistically, every home in the near future will be required to be built this way, but why wait when you can start now!

See you there!
We hope this part of the summer finds you enjoying a break, just back from one or perhaps just getting ready to go. Maybe you’re sprinkling mini breaks through these warm months when we can get outside more easily.
At EkoBuilt, we’re very excited about the engagement we continue to enjoy with so many of you, so many folks interested in sustainable living, coach homes and tiny homes, comfortable high performance homes of many different shapes and descriptions.
We hear from some of you every week, and we’re bursting with news on our latest projects and an update on the first Eko Community that we’re hoping to see move to the design phase shortly. We hear from folks interested in forming an Eko Community regularly, and we encourage you to get your name on our list if you’re keen in participating in one.
If you’ve got any camping or outdoor cooking with a campfire on the horizon, you might enjoy Feast by Firelight by Emma Frisch, a book we recently came across.
Nearly two years ago we first wrote a post here about the Trees for Tomorrow and Green Acres programs that help homeowners wishing to reforest a part of their own land. It’s such a great idea, that we’re writing here about it again. This spring they planted the six millionth tree.
For many of us building a custom home, we’ve chosen to build on a patch of land outside of the city. That often means we have some extra space that can be considered for various uses. Sometimes there are obvious uses that come to mind for ourselves, whether gardening, small scale farming, recreation, etc.
Have you considered planting trees in volume? Planting seedlings for future trees will improve a property and its value, provide wildlife with new habitat, help to cut down on land erosion, create shade and livable spaces, and even offset carbon emissions.
For any landowner with property sitting idle, the Rideau Valley Conservation Authority offers technical and financial assistance to reforest that space.
Applicants for 2019 Tree Planting Season
The RCVA is now looking for new planting areas for the 2019 tree planting season. Could it be you? Or someone you know? Anyone with a large area of one acre or more for planting is welcome to contact the RCVA for a site visit:

Imagine your property filled with more than an acre of trees for a small fraction of the real investment required, where all of the hard work is done by others, including site assessment, clearing and planting. The program includes survival assessments in the early years.
The only commitment on the part of landowners is to cover the heavily subsidized planting effort (this really is a good deal), order a minimum of 500 trees, and to make reasonable efforts to protect the trees from damage.
There is also a Butternut Recovery Program for the endangered butternut species.
We were delighted to take part in the Toronto Green Living Show this year. It was a great event that really felt like a 21st-century show!
There were electric cars from a number of different companies, lithium ion power walls, vertical gardens for your living room, vertical farming out of a container, and geodesic domes where you can grow produce year round even in our climate.
We loved being part of the showcase of green living options and really enjoyed talking about about our electrically operated homes, which are designed to cost just pennies a day to operate.
Congratulations to the winner of our Eco-Feu raffle at the show, Stephanie Hahn of New Hamburg, Ontario.
Stephanie won a Cartier tabletop unit from Eco-Feu. These ethanol units make perfect centerpieces and/or accent lighting. Burning for 2 to 3 hours, they feature a soothing, vibrant, real flame.
The future is now and we need to embrace it! Photos below from the event.

The EkoBuilt Model Home will be open for public viewing on Saturday and Sunday this weekend from 9am to 5pm each day, as part of Green Energy Doors Open Ottawa ’17. We hope you’ll come out and visit our four-bedroom passive house just west of Ottawa. Just stepping into the house you’ll feel the difference.
The EkoBuilt Passive House is our premier offering for home owners seeking the best investment, exceptionally low energy consumption, and comfort from a home that is also supremely healthy. We offer 13 designs, all of which can be customized to meet your specific needs and preferences.
Almost all of our conversations begin with the passive house and what it means for home owners. To aid these conversations and to support your research into the best home for you, we recently developed an illustration that shows the component parts of what we call the Eko Solar Engine.
Throwing our doors open this weekend offers a perfect opportunity to ‘see’ the solar engine in action and to ask questions. We look forward to meeting you!

Inexpensive and Simple
When many of us hear the term ‘off-grid’ in terms of our homes, it’s easy to think it must be difficult or costly to get a off-grid, however it is actually very easy to implement and not terribly expensive. When viewed in line with typical utility bills, it simply makes sense.
A typical off-grid system might range from $20-$30k to purchase, which is a significant upfront investment for most of us, but seen over the duration of a mortgage, it would actually translate into a very manageable monthly payment, e.g. $170 / per month. This is actually more affordable than many typical monthly utility bills for homeowners.
All change…or at least, a significant shift
At this point in time, almost every off-grid project requires a generator, because the sun is not always shining and the wind is not always blowing, and the capacity for storing the energy generated by these sources in batteries simply hasn’t developed sufficiently.
The problem with conventional off-grid systems is that they require propane or gas, which are petroleum based fuels. As we all know, this represents a simply unsustainable energy supply. Which is why we turn to biofuel.
Why not use readily available bio-fuel?
We recommend using a generator that can burn vegetable oil or bio diesel. These are the fuels of the future as they are non-petroleum based and renewable.
A European company, Gelec Energy, has a great selection of generators, including ones engineered for use with vegetable oil/biofuel.
With this technology, no one is reinventing the wheel; they are simply making use of existing diesel technology developed over 100 years ago. After all, deeply concerned about the pollution that accompanied the age in which he lived, Rudolph Diesel originally designed his engine so that it could run off peanut oil…
As a fuel, bio diesel is also reasonably affordable, costing as little as $.60 per litre, compared to much closer to a dollar per litre for gas at the pump.
What this looks like
In the summer period (mid-March to mid-October) an off-grid house is designed to run off solar PV panels and batteries. In the winter period (mid-October to mid-March) it’s engineered to run off a combination of solar PV, batteries, and the generator.
On average, a full-size family home will use 24 kWh per day in the warmer months, and 30 kWh per day in the cold season. The house can run directly off solar PV when the sun is shining, but here are the factors to consider for overcast days:
- Battery storage is 15 kWh.
- Batteries experience on average .5 charge cycles per day during the summer period and one charge cycle per day during the winter period.
- Batteries cost $15,000 and are guaranteed for 3,000 charge cycles which equates to a battery lifetime of 12 years. This averages out to $1,250 per year.
- Generator cost is $15,000; with limited run time it should last approximately 30 years, resulting in an annual cost of $625.
- On average, the generator needs to produce 15 kWh per day during winter. The generator can do this with 1.5 L used vegetable oil or biodiesel: 1.5 L x 150 days = 225L x $0.60 per litre = $135/year.
Total annual costs
- Cost for bio diesel approximately $0.60 per litre = $135 per year
- Generator cost amortized over 30 years = $625 per year
- 6 kW solar array and inverter $15,000 to last 50 years or more = $300 per year
- Batteries amortized over 12 years = $1,250 per year
Total = $2,310 per year. We conservatively estimate that this is 50% less than what most full-size family homes cost to keep heated and cooled when connected to the grid.
