Abstract: Objective To establish a method for energy montoring and assessing energy conservation methods in laboratory animal facilitiy. Methods Annual energy consumption situation of laboratory animal facilitiy was assessed by an energy monitoring system. The total energy consumption of electricity, steam, heat and cooling capacity, etc. were recorded and analysised . The square meter energy consumption of the facility was calculated and compared with other buildings in our campus. Two different steam supply ways, pipeline and electric steam boiler, were measured by the energy monitoring system. Results Consumption of electricity, steam, heat and cooling capacity were 1.725 GWh、12244.90 and 1.497 GWh, respectively. The total electric and steam consumption of the facility were 2.783 GWh and 12553.29 GJ. Compared with 4 different buildings monitored, the energy consumption of animal facility was 8.52 to 21.88 times more. The system showed steam consumption of two different supplying ways were 9925.00 GJ and 2651.00 GJ, respectively. Conclusion The energy monitoring system could real-time reflect the energy consumption of our laboratory animal facilities. It was availible for energy consumption statistics and energy-saving administration. According to our results, electric steam boiler was a more economical way compared with pipe supplying.
