Proposed by Turkish scientists, the system design consists of combining rooftop PV with a ground source heat pump in a greenhouse used for tomato, cucumber and lettuce cultivation. The solar array ...

Researchers in Sweden sought to raise the efficiency of ground source heat pumps by combining their operation with that of PVT systems and free cooling. Through a series of simulations, they found ...

Illustration by Sarah Cheney. Imagine a home in which the temperature is always comfortable, yet the heating and cooling system is out of sight. That system performs efficiently but doesn’t require ...
