The proposed activity (duration: 6 months) will investigate the design parameters of the greenhouse system in order to develop a new kind of greenhouse structure viable for the Northern Territories in extreme weather conditions. The present study will first carry out thermal analysis for energy calculations of Heating, Ventilation and Air-conditioning system (HVAC) of the structure. It will provide necessary data such as inside temperature to run numerical simulations in the next stage. In the next stage, 3-dimensional computer model of the greenhouse will be built. Numerical simulations will be performed to identify very important design parameters, for example, air flow, temperature distribution and moisture level inside the greenhouse with various boundary conditions. Such analysis will help to decide on various components (spacing, light intensity, temperature, humidity level etc.) and optimize design for maximum output. Thus the numerical analysis will serve as a guiding tool for improving the performance of the greenhouse system as well as a foundation for more detailed analysis for future research and development. In the next phase, a small scale prototype greenhouse structure will be developed and testing will be carried out and numerical simulation results will be verified with actual results. REMASCO, will partner with UoG in the proposed study, and use the results in investigating the business case for developing the optimized green house system. Project like this will allow diversifying Canadian economy by maximizing the value of natural resources and stimulating green investment, green innovation and green jobs. Economy develops as more employment opportunities, energy efficiency, fresh food supply for local people, and environment friendly technology yields benefits to Northern Territories' residents and businesses.

拟议的活动(为期6个月)将调查温室系统的设计参数，以便开发一种在极端天气条件下适用于北方领土的新型温室结构。本研究将首先对该建筑采暖、通风和空调系统的能量计算进行热分析。它将为下一阶段的数值模拟提供必要的数据，如室内温度。在下一阶段，将建立温室的三维计算机模型。将进行数值模拟，以识别非常重要的设计参数，例如，在各种边界条件下温室内的气流、温度分布和湿度水平。这样的分析将有助于确定各种组件(间距、光照强度、温度、湿度等)。并优化设计以实现最大产量。因此，数值分析将作为改进温室系统性能的指导工具，并为今后的研究和开发提供更详细的分析基础。在下一阶段，将开发一个小型温室原型结构，并进行试验，数值模拟结果将与实际结果进行验证。REMASCO将在拟议的研究中与UOG合作，并利用研究结果调查开发优化的温室系统的商业案例。这样的项目将使加拿大经济多样化，实现自然资源价值的最大化，并刺激绿色投资、绿色创新和绿色就业。随着更多的就业机会、能源效率、当地人的新鲜食品供应以及环保技术为北部地区的居民和企业带来好处，经济得到了发展。
