How to design for thermal comfort in a home

...comfort: A more accurate reading than air temperature for maintaining a comfortable indoor environment would be the MRT (mean radiant temperature), which is a measure expressing the influence of surface temperatures on occupant comfort. An even more functional measure of thermal comfort in a building would be the o...

The pros and cons of thermal mass in buildings

...thermal mass in homes: A lot of thermal mass in a home can help naturally balance temperatures in spring and fall when days are warm but nights are still cool. That will either increase comfort or reduce the need for heating and cooling. Heat security: Having significant thermal mass in your home can be a big advan...

What is a thermal bridge and why is it so important to break it?

...thermal bridges: It is not only sensible to address thermal bridging in construction, it is becoming law. Recent revisions to building codes have increased the thermal requirements of building enclosures in many regions, including requiring a thermal break. Contrary to common assumptions, the insulation value...
