Passive solar architecture is a design strategy that optimizes a building’s energy efficiency and long-term sustainability. By relying on a building site’s solar orientation and climate, sustainable ...

Over the past two weeks, I’ve written about two relatively obscure passive solar heating strategies: Isolated gain using sunspaces, and; indirect gain using a Trombe walls. This week I’ll cover a far ...

Since ancient times, people have found ways to use the sun’s heat to stay warm or keep cool. They built homes from clay and other materials that hold heat well, and they placed them in ways that ...

A passive solar-heated home needs no solar panels to heat or cool it. Rather, the energy used to heat and cool a house comes directly from the sun through skylights and windows. Some of that energy is ...

There isn’t a strict definition for what makes a home "solar" — it just has to use energy from the sun in some capacity. If you’re building a new home, it makes sense to do it in a way that employs ...
