DIY radiant floor installation

...energy efficiency. Heating a floor increases the temperature differential between the concrete and the ground below it, which increases the rate of heat loss. Contrary to common beliefs, heat does not rise. Warm air rises, but heat goes everywhere. You need only pick up a hot coffee in a ceramic mug to answer this qu...

Properly insulating basements and concrete slab floors

...energy efficiency. The rate of heat loss through foundation walls also varies between below-grade and the parts above. Over a heating season, there will be much more heat loss through above-grade walls than those below. Therefore, with one wall and two rates of heat transfer, this leaves the dilemma of insulating m...

Wildfire Smoke & How to Keep it Outside Homes
Healthy indoor air quality

How to keep wildfire smoke out of Green Homes with mechanical ventilation systems?

...energy efficiency; indoor air leaks waste cooling power during summer and heating power during winter - which is why using HRV and ERV systems is recommended to reduce energy loss whilst ventilating homes. When there are wildfires in the area though causing a smoky atmosphere, an airtight envelope also helps prevent th...

All about solar thermal collectors

...energy as the entire surface area is a black collector. So, in the absence of other factors, a flat plate will produce more energy than an evacuated tube design in summer, because it has a greater amount of collector surface area, and ambient air temperature is less of a problem. Conversely, in winter, air temperatur...
