In a building-integrated agriculture (BIA) space, peak loads must be estimated to size HVAC equipment in order to maintain indoor air conditions that enhance crop growth. However, the estimation of the rates of heat gain/loss induced by the crops and their impact on heating and cooling loads have only been sparsely addressed. The present study proposes a workflow to estimate the impact of crops on a BIA space peak loads. The building, BIA space and crops – lettuces – are modeled in TRNSYS 18, while loads for design day conditions are assessed by completing a parametric study that varied the cultivated density (CD), the indoor air conditions (temperature and humidity) and the leaf area index (LAI) of the crops. Compared to the baseline peak loads, the estimated sensible heating and latent cooling peak loads of the BIA space at the highest CD for a LAI of 2.1 are 3.6 to 3.7 and 1.1 to 2.1 times higher, while being 13.3 to 14.0 and 6.0 to 9.9 times higher for a LAI of 10. The results show the importance of considering crops in estimating peak loads to size HVAC equipment and promote crop yield.

估算农作物对建筑一体化农业空间峰值负荷的影响

在建筑集成农业(BIA)的空间中,必须估算峰值负荷以决定HVAC设备的大小,以维持室内空气条件以促进作物生长。但是,仅对稀疏处理了由农作物引起的热量增加/损失速率及其对加热和冷却负荷的影响的估计。本研究提出了一种工作流,以估计农作物对BIA空间峰值负荷的影响。在TRNSYS 18中对建筑物,BIA空间和农作物-生菜进行建模,同时通过完成一项参数研究来评估设计日条件下的负载,该研究会改变耕种密度(CD),室内空气条件(温度和湿度)和叶片作物的面积指数(LAI)。与基线峰值负载相比,
