Comprehensive Evaluation of a Landscape Fabric Based Solar Air Heater in a Pig Nursery

Supplementing fossil fuels with solar air tempering for brooding young livestock could reduce energy use and improve indoor air quality. Metal transpired solar collectors (TSC) are effective but too expensive for heating livestock buildings. An inexpensive 12.7 m<sup>2</sup> dark grey la...
