Food security and affordability are a prolonged problem in northern and remote communities who are heavily dependent on the South for food. Community gardens and greenhouses are seen as viable and sustainable solutions to minimize the reliance on costly foods imported from the South. Energy consumption, moisture control, and ventilation of the greenhouse are big problems. The temperature difference between outdoors and indoors of a greenhouse could be as high as 80°C. Extensive indoor moisture and its exhaust make the issues very complicated. Building envelope plays a vital role in controlling the temperature and humidity of a greenhouse. The OCN Smart Farm, a Manitoba-based Company, plans to adopt and commercialize a South Korean technology to grow vegetables, herbs, and fruit in shipping containers. The technology was initially developed and commercialized by Korea Agriculture System & Technology (KAST) Engineering Co. Ltd. While the OCN Smart Farm is 900 square feet of growing capacity (4 lanes x 4 layers each), the OCN Smart Farm will utilize shipping containers to grow crops. The container is designed for a South Asia region, which has an entirely different climate. The objective of this project is to adopt the KAST technology for the Canadian environment. The adaptation of the KAST technology is through modification and adjustment of the building envelope. Three building envelope systems will be developed in this project. These building envelope systems will be tested in dual-environmental chambers, while temperature humidity and heat flux sensors are installed in the systems. The sensors measure the variables as the chambers are operating. Based on the findings of these tests in a controlled environment, the optimum building envelope system will be selected for prototyping and field-testing in extreme climatic conditions.

粮食安全和负担能力是严重依赖南方粮食的北方和偏远社区的一个长期问题。社区菜园和温室被视为可行和可持续的解决办法，可最大限度地减少对从南方进口的昂贵食品的依赖。温室的能耗、湿度控制和通风是大问题。温室的室外和室内之间的温差可能高达80°C。大量的室内湿气及其废气使问题变得非常复杂。建筑围护结构对温室的温湿度控制起着至关重要的作用。OCN智能农场是一家位于马尼托巴省的公司，计划采用韩国的一项技术，在集装箱中种植蔬菜、草药和水果，并将其商业化。 该技术最初由韩国农业系统与技术（KAST）工程有限公司开发和商业化。虽然OCN智能农场的种植能力为900平方英尺（4车道x 4层），但OCN智能农场将利用集装箱种植作物。该集装箱是专为南亚地区设计的，那里的气候完全不同。该项目的目标是在加拿大环境中采用KAST技术。KAST技术的改造是通过修改和调整建筑物的外壳。本项目将开发三种建筑围护结构系统。这些建筑围护系统将在双环境室中进行测试，同时在系统中安装温度湿度和热通量传感器。传感器在腔室运行时测量变量。根据在受控环境中进行的这些测试的结果，将选择最佳的建筑围护结构系统，在极端气候条件下进行原型设计和现场测试。
