Energy efficiencies - strategies for minimizing utility costs in the barn.

This paper discusses the importance of maintaining both the desired environmental temperature for the pigs being housed as well as exchanging sufficient air to maintain good air quality for maximum pig performance. Equipment sizing and efficiencies are discussed as well as proper control of these devices. Additionally, various lighting options are discussed since this is another significant energy user in many swine enterprises. The paper concludes with comments regarding heat recovery, possible alternative fuels and renewable energy sources.
