Data underlying the publication: Synergetic integration of vertical farms and buildings: reducing the use of energy, water, and nutrients

Vertical farms (VF) use some resources highly efficient, but the electricity use is considerable and they produce a significant amount of waste heat. The paper underlying this dataset investigates how the integration of vertical farms in buildings could reduce the use of energy, water, and nutrients collectively across both entities by leveraging potential resource synergies. The integration of vertical farms is considered in apartments, offices, restaurants, swimming pools, and supermarkets located in the Netherlands. The main focus of this research was to reuse the residual heat produced by the artificial lighting systems of the vertical farm within the host building’s heating system.Therefore, the quantity of heat produced by the VF and temperatures had to be determined first. The current cooling and dehumidification system was studied. The total energy use of this system was calculated using mathematical simulations of the refrigerant cycle of the HP used, together with calculations for the used heat exchangers and mixing values. These calculations are described within the research paper, and results discussed. More detailed outcomes are presented in this dataset. The tab "VF_Ch" describes the energetic characteristics of the VF used to calculate the cooling demands. In the tab "VF_CDS" presents the calculations made to define the energy use of the cooling and dehumidification system of the VF.Within the next step different strategies are developed that can supply the residual heat produced by the VF to the heating system of the different host building types. Three strategies were selected. Two for direct integration without seasonal energy storage (A1 and B1), and one using aquifer thermal energy storage (E2). Strategy A1 used a heat exchanger to supply the heat of the VF to the building, due to the low temperature this strategy was only applicable to swimming pools. Strategy B1 used a heat pump to upgrade the residual heat temperatures of the VF to that of the underfloor heating system of the host building. Strategy E2 used two HPs and an aquifer thermal energy storage (ATES) system to supply the VF heat to the building, and to store heat produced by the VF outside of the building's heating season for later usage during the heating season. More information on these three strategies is found in the paper. The performance calculations of these three strategies are found in tabs "Int_A1", "Int_B1" and "Int_E2", and are described in more detail in the paper and its appendixes. Within the paper, the performances of the three integration strategies were compared to those of an non-integrated VF and host building. The VF is scaled to provide all heat to the host-building typology under study. Within the non-integrated approach the energy use of the same size of VF using the non-integrated cooling and dehumidification system as calculated in Tab "VF_CDS", and that of the non-integrated/baseline host-building are summed. The different baseline host-building typologies use an air-source HP for heating and cooling. These calculations are presented in the tabs "BS_ap", "BS_off", "BS_res" and "BS_sw", for an 80m2 apartment with an energy performance label BENG (nearly energy neutral), A and C, for large and small offices with energy labels BENG, A, and C, for a 250m2 restaurant, and for an indoor and outdoor swimming pool respectively.<br><br>

垂直农场（Vertical Farm，以下简称VF）在部分资源利用上效率突出，但电力消耗量较大，且会产生大量废热。支撑本数据集的研究论文探讨了如何通过挖掘潜在的资源协同效应，实现建筑与内嵌垂直农场的能源、水及养分消耗的协同削减。该研究以荷兰境内的公寓、办公楼、餐厅、泳池及超市为场景，探讨垂直农场与建筑的整合方案。本研究的核心目标是将垂直农场人工照明系统产生的废热回收利用至宿主建筑的供暖系统中，因此首先需要明确VF的产热量与温度参数。研究团队对现有冷却除湿系统展开分析，通过对所采用热泵（Heat Pump，HP）的制冷剂循环进行数学模拟，并结合换热器与混合工况的计算，得出该系统的总能耗。上述计算过程已在研究论文中详述并讨论，本数据集则提供了更为详尽的计算结果。工作表标签"VF_Ch"用于说明用于计算冷却负荷的VF的热工特性；"VF_CDS"标签页则展示了用于计算VF冷却除湿系统能耗的相关参数。

后续研究团队开发了多种可将VF产生的废热输送至不同类型宿主建筑供暖系统的方案，最终选定三种策略：两种为无需季节性储能的直接整合方案（A1与B1），另一种采用含水层热能储存（Aquifer Thermal Energy Storage，ATES）系统的方案（E2）。策略A1通过换热器将VF的废热输送至建筑，但由于废热温度较低，该方案仅适用于泳池建筑。策略B1采用热泵将VF的废热温度提升至宿主建筑地板供暖系统所需的温度等级。策略E2采用两台HP与ATES系统，将VF的废热输送至建筑，同时可将非供暖季产生的废热储存起来，待供暖季再投入使用。关于这三种策略的更多细节可参阅研究论文。三种策略的性能计算结果分别收录于工作表标签"Int_A1"、"Int_B1"与"Int_E2"，相关详细说明已刊载于研究论文及其附录中。研究论文中，将三种整合策略的性能与未整合VF及基准宿主建筑的性能进行了对比。本数据集所涉及的VF已按比例缩放，可向研究中的各类宿主建筑提供全部所需热量。在未整合的基准场景中，将采用"VF_CDS"工作表标签中计算所得的同规模VF（使用非整合冷却除湿系统）的能耗，与未整合/基准宿主建筑的能耗进行求和。各类基准宿主建筑均采用空气源热泵（Air-source Heat Pump）实现供暖与制冷。上述基准场景的计算结果分别收录于"BS_ap"、"BS_off"、"BS_res"与"BS_sw"工作表标签中，分别对应：建筑面积80㎡、能源性能标识为近零能耗建筑（Building Energy Neutral，BENG）、A类及C类的公寓；能源标识为BENG、A类及C类的大、小型办公楼；建筑面积250㎡的餐厅；以及室内、室外泳池。
