Does hydronic radiant cooling work?

...thermal mass inside the home, so if you invest in a very efficient wall assembly and airtight building envelope, you can often wait out a heat wave (at least on the main floor) without the need for artificial cooling, as the concrete absorbs the ambient heat from the home. That and even a small localized heat pump may ...

Are there any updates on the progress of the second demonstration house?

I am most curious about the effectiveness of the air tube floor heating system. The house is now standing, it is the first house built of our new prefab modular kit houses available across Canada and the US. you can see a full break down of the mechanical systems, energy performance and total carbon footprint on this p...

What is the Kenogami House heating system?

...thermal battery, to avoid overheating during sunny winter days that provided too much passive solar heat. How well did that experiment work at collecting excess heat?   It was also mentioned using the radiant hydronic floor, moving purposely heated water in the radiant tubing to help balance the excess heating. My unde...

Can a solar thermal air system be coupled to an HRV for heating incoming fresh air?

...battery’, you already have that – the concrete floor. Assuming you have at least 3 or 4 inches of concrete in your floor, it will most likely absorb as much solar-generated heat as you could possibly throw at it during a sunny winter day, so I would personally skip the step of including a separate thermal battery and f...
