Climate Zones in USA & Canada for Building Homes

...passive solar gain a home can hope for . Climate zones in USA & Canada are important when building homes But the principles of building science remain the same in all climate zones ; in relation to moisture movement though walls, and thermal dynamics (meaning how heat moves from one place to another). To better und...

Condensation on windows in our homes - why is it there? - how to stop it?

Condensation on windows is a pain but is it a problem & how to stop it?

...Passive House , Net Zero Energy and high-performance homes is consistently making the most of Passive Solar Gain , having a home where each day starts with fogged over windows is absolutely a huge detriment. A hidden effect of condensation on house windows is that once the sun does come up, which could and should be he...

...solar where liquid passing through tubes collects heat to be redistributed through your house. According to NASA, every day the sun provides the earth with 10,000 times the total energy consumed by humans. A passive solar house is simply one that has been designed to take advantage of that. Passive solar heating is...

Thermal batteries: how to passively store heat

...heated by solar thermal panels. Even this type of system is not new, the first house in the United States with an active solar heating system was built In 1939 on the MIT campus (Massachusetts Institute of Technology), and sat on top of a huge water reservoir that was heated by thermal solar panels. MIT Solar Hou...

Off-grid home with solar PV & Battery backup
Off-grid and Net-Zero Housing

Thinking about renewable home energy and a battery backup?

...passively-heated homes, it's really just a traditional wood stove that will save your bacon (or help you cook it) when the power is out. A photovoltaic (PV) solar array that is designed to run the basic systems of your home, excluding heat, likely wouldn't be enough to heat your whole house if you diverted power to h...

Understanding thermal performance

...heat loss from the warmer interior to the colder exterior, in some cases R-value can actually prevent potentially beneficial heat gain from a warm surface, such as a roof. The optimal balance of preventing heat loss and allowing heat gains will depend largely on climate, assembly arrangement, and building use. In the f...

We had our zone system designed by our sponsor Uponor which ensured that the heat would be balanced as best as possible. 9: The final floor will be a polished concrete, which is completely non-toxic and very durable. The production of concrete is a heavy polluter, releasing one ton of GHGs (greenhouse gases) pe...

Skylights can be problematic in a high performance home
Windows and doors

Are skylights an asset or a liability?

...gainst skylights in terms of their energy performance . They will add a little bit of heat on sunny days in winter (with the right orientation and angle), but the heat they lose when the sun is down will far outweigh any heat they gain. The real heat gain unfortunately comes in summer when you don't want it. The most...
