Post-Occupancy Evaluation of a Cost-effective Bioclimatic Building Chamber: a diagnosis of thermal and acoustic perception of the built environment

Abstract The Cost-effective Bioclimatic Building Chamber (CBBC) is a laboratory dedicated to comparative studies on environmental comfort and building performance. In this paper, a diagnosis of thermo-acoustic comfort conditions provided by CBBC’s original configuration is presented, based on some results from a Post-Occupancy Evaluation (POE) - which also included lighting, ergonomic, and functional comfort aspects. Firstly, a brief contextualisation of POE is presented. Regarding research procedures, the paper describes CBBC’s structure and functionalities, environmental parameters monitoring, CBBC’s operation protocol, and POE’s methodology. Subsequently, the results of the first POE application are discussed, accomplished by 136 volunteers in August 2018, under forced ventilated conditions without active air conditioning. Most occupants reported thermal comfort at CBBC (84,6%). On the other hand, more than one fifth of the occupants declared dissatisfaction (19,1%) or high dissatisfaction (2,2%) with the CBBC’s noise level.

摘要 低成本生物气候建筑试验舱（Cost-effective Bioclimatic Building Chamber，CBBC）是一所专注于环境舒适度与建筑性能对比研究的专业实验室。本文基于一项涵盖照明、人机工程学与功能舒适度维度的使用后评价（Post-Occupancy Evaluation，POE）的部分成果，对该试验舱原始配置所提供的热声舒适度状况展开诊断分析。首先，本文对使用后评价进行简要的背景阐释；在研究流程部分，本文详述了CBBC的结构与功能、环境参数监测方案、试验舱运行规程，以及使用后评价的研究方法。随后，本文讨论了首次应用该评价的结果：该调研于2018年8月由136名志愿者参与，实验工况为无主动空调的强制通风环境。结果显示，多数参与者（84.6%）表示在该试验舱内获得了热舒适度；但另一方面，超过五分之一的参与者对试验舱的噪声水平表示不满意（19.1%）或极不满意（2.2%）。
