ABSTRACT Passive House Planning Package (PHPP) simulations are crucial in balancing a reduced space heat demand and reduced overheating in Passivhaus dwellings. This paper identifies the PHPP simulated overheating frequency (OF) for a dwelling in Douglas, Cork, Ireland, constructed in 2015. The measured indoor temperature is also recorded over a 12-month period. A comparative analysis of measured and simulated overheating is carried out, with two overheating thresholds of 25°C and 24°C. The simulation estimates an OF of 0.00%, for a typical year (at 25°C). The simulation relies on a dwelling average temperature, where the equivalent measured OF for the test year is 2.64%, derived from a volume-weighted mean indoor temperature (T vm). At a reduced threshold of 24°C, the measured OF is 4.67%. Measurements within 6 independent zones identify 52.61% of readings above 25°C are eliminated by using T vm. The representation of overheating as a percentage of the year is shown to distort the effect of overheating, while the T vm value overlooks variations in zonal temperature. This paper recommends that a more robust assessment tool is developed within PHPP, to predict OF for passive house dwellings, while adopting this methodology for dwellings of Nearly Zero Energy Buildings (nZEB) standard.

Passivhaus 模拟和测量的爱尔兰典型住宅过热频率的比较分析

摘要 被动式房屋规划包 (PHPP) 模拟对于平衡减少的空间热需求和减少被动式住宅的过热至关重要。本文确定了 2015 年建造的爱尔兰科克道格拉斯住宅的 PHPP 模拟过热频率 (OF)。测量的室内温度也记录了 12 个月的时间。对测量的和模拟的过热进行了比较分析，两个过热阈值分别为 25°C 和 24°C。模拟估计典型年份（25°C）的 OF 为 0.00%。模拟依赖于住宅平均温度，其中测试年份的等效测量 OF 为 2.64%，源自体积加权平均室内温度 (T vm)。在 24°C 的降低阈值下，测得的 OF 为 4.67%。6 个独立区域内的测量确定了 52 个。使用 T vm 消除了 61% 高于 25°C 的读数。过热占一年的百分比表示会扭曲过热的影响，而 T vm 值忽略了区域温度的变化。本文建议在 PHPP 中开发更强大的评估工具，以预测被动式住宅的 OF，同时对接近零能耗建筑 (nZEB) 标准的住宅采用这种方法。
