Summary

This paper presents an energy analysis of the Polar Continental Shelf Program (PCSP) facility located in Resolute, NU. The study focuses on the evaluation of innovative energy efficiency strategies including on-site cogeneration and renewable technologies such as wind and solar. Developed energy models were validated using data collected from installed metering systems recording the electricity, heating fuel and hot water consumption of six buildings that make up the PCSP Resolute facility. A preliminary energy audit identified short term energy efficiency measures that could be implemented to reduce greenhouse gas (GHG) emissions by 15% and reduce utility costs by 12.5% annually. Proposed innovative strategies are designed to build upon the suggested short term energy efficiency measures to achieve significant utility cost savings. From simulations it is estimated that almost all electricity can be produced by on-site generation and the heat recovered from the generators can be used to meet close to 50% of the space heating loads, resulting in close to $600,000 (~50%) savings in annual utility costs from the proposed short term measures. The feasibility of sea water heat pump system is also evaluated to efficiently meet a portion of the building heating loads, while increasing the demand on the combined heat and power system. The use of a sea water heat pump would help save an additional $40,000 (~7.0%) in utility costs annually. In comparison, the use of wind and solar photovoltaic renewable energy technologies can achieve more savings. Sized to meet the base electrical load of the facility, the use of these technologies are estimated to save $175,000 annually.
