在城市化进程中，装配式办公建筑以其方便灵活的特点在建筑工地上得到了广泛的应用。为研究标准有效温度（SET*）和预测平均通风量（PMV）模型在预制建筑工地办公室（PCSO）的适用性，在广州市选取了建筑工地，在夏、秋、冬三季进行了热参数测量和问卷调查。共回收有效问卷1505份。在适应性理论的基础上，利用实地调查数据，扩展了原PMV模型和SET* 模型的适用性和可靠性。本研究发现，目前研究中得到的SET* 和PMV模型不能准确地评价活动房屋中人的热舒适性。在冷态条件下，原始标度低于MTSV，而在暖态条件下，结论则相反。此外，通过计算发现，在三个不同季节，自然SET* 值均高于偏好SET* 值。优选SET* 的差异接近1 °C。对两类模型的数值进行了修正，使其能更准确地预测和评价活动板房的热舒适性，从而拓宽了PMV和SET* 模型的应用范围。因此，修改后的模型可以用来预测热舒适的预制建筑工地办公室。
In urbanization, prefab buildings for office use are extensively utilized on construction sites owing to their convenience and flexibility. To study the applicability of standard effective temperature (SET*) and predicted mean vote (PMV) models in prefab construction site offices (PCSO), combined thermal parameter measurements and questionnaire surveys were conducted on selected construction sites in Guangzhou during the summer, autumn, and winter seasons. A total of 1505 valid questionnaires were collected. Based on the foundation of the adaptability theory, the data obtained through field studies were used to expand the applicability and reliability of the original PMV model and SET* model. This study found that the SET* and PMV models obtained in the current study cannot accurately evaluate the thermal comfort of people in the prefab building. In the cool condition, the original scale was lower than MTSV, and the conclusion is opposite under warm conditions. In addition, through calculation, it can be found that the natural SET* values were higher than the preferred SET* in three different seasons. The difference in preferred SET* was near 1 °C. The numerical values of the two types of models have been revised so that they can more accurately predict and evaluate the thermal comfort of a prefab building, thereby broadening the application scope of the PMV and SET* models. The modified models can thus be used to predict thermal comfort in prefab construction site offices.
