An eQUEST model was developed to conduct a simulation study of a natural gas engine-driven heat pump (GEHP) for an office building in Woodstock, Ontario, Canada. Prior to the installation of the GEHP, the heating and cooling demands of the office building were provided by rooftop units (RTUs), comprising of natural gas heater and electric air conditioner. Energy consumption for both GEHP and RTUs were monitored for operation in alternating months. These recorded energy consumptions along with weather data were used in the regression analysis. The developed eQUEST models were validated and calibrated with the regression analysis results with respect to the ASHRAE Guideline 14–2014. The eventual models were then applied to investigate the potential annual energy consumption, greenhouse gas (GHG) emission and energy cost savings achieved by using the GEHP in Woodstock, and other cities in Canada, particularly in Ontario.

开发了一个eQUEST模型来对加拿大安大略省伍德斯托克市的一栋办公楼进行天然气发动机驱动的热泵（GEHP）的仿真研究。在安装GEHP之前，办公楼的供暖和制冷需求是由屋顶单元（RTU）提供的，其中包括天然气加热器和电动空调。监测GEHP和RTU的能耗，每隔几个月运行一次。这些记录的能源消耗以及天气数据被用于回归分析。根据ASHRAE指南14-2014的回归分析结果，对开发的eQUEST模型进行了验证和校准。然后将最终模型应用于调查潜在的年度能耗，
