Decentralized Energy Generation for LEED, Passive House & Green Homes
Renewable energy

Which is the Best Type of Home Energy Generation for Green Homes?

Home Energy Generation, which option is best? How the electrical grid is fed near you will be a huge factor in determining the carbon footprint of your home, with or without your own renewable power generation such as having solar panels on your roof . If you live near a windfarm, that's where most of your power com...

DIY Lunos HRV air exchanger installation video

...decentralized system with a series of self-contained units, each with their own ceramic heat exchange core. They work in pairs blowing in opposite directions to maintain air pressure, and reversing directions every 90 seconds or so, which is how they absorb and release heat. The video should give you a pretty good id...

Off-grid and Net-Zero Housing

A Toronto Off-grid home 20 years later; how did it fare?

...decentralized manner. However, that can still be a lot cheaper than the cost of bringing municipal services such as water lines and hydro poles for example, from a distant hookup. In such remote locations, there is often no option but to go it alone. But in the heart of an urban core such as downtown Toronto, we find...

DIY radiant floor tubing installation video

Here is our DIY video of how to lay down tubing for our radiant floor in the Edelweiss House. We have a 10 zone system, allowing floor temperatures in each room to be controlled independently. HePex tubing was provided by Uponor, who also use building plans to give customers a zone plan to follow making the install ...

Hydronic heating

Similar to electric baseboards, hydronic heating systems facilitate zone heating as you can keep different rooms at different temperatures. Though different from electric resistance heating, hydronic systems are ultimately still using electricity to generate heat, so all the same environmental realities apply. Heati...

How to design for thermal comfort in a home

Have you ever noticed that at times you can feel cold in your home even though the air temperature is exactly where you like to keep it? That's because, contrary to what most of us think, air temperature is not the main factor that determines human comfort in a building. To illustrate a point, let's start outdoors. ...

DIY radiant floor installation

There is some debate in performance building circles, particularly in the Passive House community as to whether or not you can add enough insulation below a concrete floor to eliminate the need for heating it. We have been on the fence about this and leaned to both sides at different times, but it seems we have now ...

Solar Radiant Heated Floor Slab Kit

Solar heated radiant floor with radiant heated hot water for a site with problem soil - expansive clay

EcoHome is in the process of building our next demonstration low-energy house , and to do so we have partnered with a company that manufactures frost-protected shallow foundations (slab-on-grade ) that are heated with air rather than liquid. There are many advantages to air-heated radiant floors over hydronic radiant ...

Insulated Radiant Floor ICF Foam Forms Heated with Air

Air-heated radiant floor slab foam forming systems

Radiant heating systems are very common in concrete floors now because they provide a very balanced and comfortable distribution of heat. Those systems are most commonly hydronic, meaning heated liquid is pumped through tubing in the concrete which then radiates that heat into the house. Hydron...
