To assess current energy consumption patterns in swine operations, a survey followed by energy audits were conducted in diff erent types of swine barns in Saskatchewan. Benchmark information showed high variability in the use of energy even among the same type of barns, indicating wide opportunities to improve energy use practices. The next step would be to use computer simulation to evaluate diff erent energy saving measures and to quantify the reduction in energy costs that can be achieved from implementation of these strategies.
