Scientists from India's PSG College of Technology have developed a passive solar module cooling technology that utilizes a hygroscopic salt to harvest atmospheric water from the air. “The objective is ...

An international research team has designed a novel cooling system for PV modules involving a phase change material (PCM), heat sink fins, and water. The experimental system utilizes passive cooling, ...

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 ...

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 ...

Small plug-in solar panels can cut energy bills for fixed-income retirees, but limits, rules and upfront costs mean the ...

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 ...

Renewable energy technologies are advancing. However, building inefficiency, HVAC loads and the urban heat island effect ...

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 ...
