Passive solar design is nothing new — it has probably been around as long as people have been building houses — and it has nothing to do with solar panels. It’s all about creating a comfortable space ...

Following the first energy crisis in 1973 there was a rush to heat homes with the sun. It was a tinkerer's paradise, with all manner of solar heating systems migrating from garage workshops to ...

As I discussed in last week’s column ("Resilience: Dramatically Better Building Envelopes," Jan. 4), a resilient home is extremely well-insulated, so that it can be kept warm with very little ...

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 ...

South Korean scientists have developed a WD-ER cooling system that can lower the operating temperature of a PV panel by up to 14.9 C, with an average heat transfer coefficient of 64.1 W/m2. A research ...

The passive-house building standard relies on lots of insulation and intentional design to use as little energy as possible for heating and cooling. "Things like 'passive house' have become more ...

Solar homes generate most of their energy from a combination of solar technologies (e.g., solar panels, solar tubes and solar windows). Most solar homes rely primarily on photovoltaic (PV) solar ...

Engineers at Osaka Metropolitan University have built an artificial-photosynthesis system that produces liquid solar fuel ...

Many homeowners are surprised to learn that most solar systems stop working during an outage — even on sunny days. That’s why many people add a backup generator (or solar batteries) to make sure their ...

German company Htrius has launched two passive exoskeletons designed to reduce physical strain and improve ergonomics for ...
