A research team at Korea University has created a passive cooling system for solar panels that uses a water desorption process and endothermic reaction dissolution process. The method is similar to ...

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 ...

Passive solar module cooling tech based on paraffin wax Egyptian researchers have used paraffin wax as a phase-change material (PCM) to reduce the operating temperatures of PV modules. They have found ...

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 ...
