The Ottawa Home & Garden Show last weekend was a tremendous experience. As ever, we enjoyed many rich conversations and answered a lot of questions. We thought we’d share some background here for our newest readers.
Who we are and how we are different?
EkoBuilt is a company committed to building homes design for the 21st-century. This means strikingly designed and deeply comfortable homes that are easily and cheaply heated and cooled with electricity.
Why do we do what we do?
It is our goal to get anyone and everyone in a quality passive house as affordably as possible. Our minimalist approach to design and investment in finding the right products/materials/systems have made this abundantly possible.
What exactly do we do?
First and foremost, we design and build low-energy homes that need no furnace or boiler.
How is this possible?
Super insulated, airtight and vapour tight construction.
What do we use for heat and air conditioning?
Even in a low energy home, heating and cooling systems are needed, but in a passive house, we just need a simple air to air source heat pump which is cheap to install and cheap to operate. These systems are not viable in conventional homes because the heating and cooling demands are too high.
On average, a passive house in winter with no sun and -30°C needs approximately 6 kWh of energy per day to keep house comfortably at 21 degrees. That’s amazing!
What about fresh air?
Even homes built to standard code require an HRV [heat recovery fresh air ventilator]. The difference is that conventional HRV units are 65% efficient, whereas passive house HRVs are 95% efficient.
The passive house unit also removes humidity which is important because these homes are vapour tight.
