When it comes to energy consumption, hoop structures provide a better option than the conventional pig shelters. This will of course depend on your own particular wants and needs. For instance, there is lesser need for installing ceiling fans or cooling units in hooped structures because they allow for excellent ventilation already with their open ends. This natural ventilation even allows for better air movement and circulation inside the hooped structure, and thereby helps to eliminate foul odors without the need for sophisticated ventilation equipment. Lights may also be necessary in hooped structures, but because of the open ends, natural light is able to better penetrate inside the hooped structure which then reduces the need to keep the lights turned on all day.
