ABSTRACT The ventilative cooling potential tool (VC tool) aims at assessing the potential effectiveness of ventilative cooling strategies by taking into account also building envelope thermal properties, occupancy patterns, internal gains and ventilation needs. The analysis is based on a single-zone thermal model applied to user-input climatic data on hourly basis. For each hour of the annual climatic record of the given location, an algorithm identifies over the occupied time the number of hours when ventilative cooling is useful and estimates the airflow rates needed to prevent building overheating. As validation of results, the ventilative cooling potential tool outputs are compared with the predictions of a building energy simulation model of a reference room in two different climates. The VC tool is particularly suitable for early design phases, providing building designers with useful information about the level of ventilation rates needed to offset given rates of internal heat gains.

通风降温气候潜力评估工具

摘要 通风降温潜力工具（VC 工具）旨在通过考虑建筑围护结构热性能、占用模式、内部增益和通风需求来评估通风降温策略的潜在有效性。该分析基于应用于用户输入的每小时气候数据的单区热模型。对于给定位置的年度气候记录中的每一小时，算法都会在占用时间内确定通风冷却有用的小时数，并估计防止建筑物过热所需的气流速率。作为对结果的验证，将通风冷却潜力工具输出与两种不同气候下参考房间的建筑能源模拟模型的预测进行比较。
