A greenhouse climate-crop yield model was adapted to include additional climate modification techniques suitable for enabling sustainable greenhouse management at high latitudes. Additions to the model were supplementary lighting, secondary heating and heat harvesting technologies. The model: 1) included the impact of different light sources on greenhouse air temperature and tomato production 2) included a secondary heating system 3) calculated the amount of harvested heat whilst lighting was used. The crop yield model was not modified but it was validated for growing tomato in a semi-closed greenhouse equipped with HPS lamps (top-lights) and LED (inter-lights) in Norway. The combined climate-yield model was validated with data from a commercial greenhouse in Norway. The results showed that the model was able to predict the air temperature with sufficient accuracy during the validation periods with Relative Root Mean Square Error

侧重于额外光、热收集及其验证的温室气候产量模型

对温室气候作物产量模型进行了调整，以包括适用于在高纬度地区实现可持续温室管理的其他气候改变技术。对模型的补充是补充照明、二次加热和热收集技术。该模型：1) 包括不同光源对温室空气温度和番茄产量的影响 2) 包括二次加热系统 3) 计算使用照明时收获的热量。作物产量模型没有修改，但在挪威的半封闭温室中种植番茄进行了验证，该温室配备了 HPS 灯（顶灯）和 LED（内灯）。联合气候产量模型通过来自挪威商业温室的数据进行了验证。
