Concrete floors and timber frame as thermal mass

The pros and cons of thermal mass in buildings

Dense materials hold more heat than light fluffy stuff does. This can work for or against you.… Materials in a home that act as thermal mass are things like concrete, masonry, ceramic tiles, even a large volume of wood like timber frames. Intentionally adding greater amounts of thermal mass in a building can be an adv…

Phase change building materials - natural heat storage in buildings

When a substance melts or solidifies, it absorbs or releases energy. Materials that do that at room temperature can help regulate temperatures in homes.…   This article was inspired by a podcast I heard at Positive Energy, where I have yet to hear a podcast that I didn't want to listen to a second time, so check them …

Thermal batteries for passive solar design

Thermal batteries: how to passively store heat

Energy modeling simulation of heat loss through thermal bridging

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

Thermal bridges in walls can reduce the overall performance of a home.
