2001年，普罗维登斯、里约热内卢、三层住宅和单户住宅开始实施一项改善室内空气质量的计划。2001年至2004年冬季，在37栋建筑的71个住宅单元的游戏室、卧室和地下室中放置了温度和湿度数据记录设备。根据每个测量位置的室内和室外温度和湿度测量值计算室内蒸汽压值。室内和室外蒸汽压之间的差异——蒸汽压过量——是分析的主要工具。讨论了影响结果质量的因素，包括:设备校准、室外天气测量的可靠性和室内测量的连续性。这项研究的结果是在ISO 13788的框架内进行的，ISO 13788允许将这些建筑与欧洲住宅建筑进行蒸汽压超标比较。 本文讨论了研究中发现的蒸汽压超标现象，即垂直堆叠的住宅单元中的湿度、游戏室中的基础条件中的湿度和干燥度与卧室中的标准代表性评估相比的影响。本文对三年的数据进行了分析。早些时候发表在《建筑物九》上的一篇论文提供了五个月的数据结果。数据以适合与其他类似温度和湿度数据进行比较的格式呈现。引文:2010年国际会议热性能

A program to improve indoor air quality in Providence, RI, triple-deckers and single-family homes was begun in 2001. Temperature and humidity data logging equipment was placed in playrooms, bedrooms, and basements in 71 dwelling units in 37 buildings from winter 2001 to 2004. Indoor vapor pressure values were calculated from indoor and outdoor temperature and humidity measurements for each measurement location. The difference between indoor and outdoor vapor pressure—the vapor pressure excess—was the principal tool of analysis. Factors that influence the quality of the results are discussed, including: calibration of the equipment, reliability of outdoor weather measurements and continuity of the indoor measurements. Findings from this study are viewed within the framework of ISO 13788, which permits a vapor pressure excess comparison of these buildings to European residential buildings. The vapor pressure excess findings from the study are discussed with regard toThe effect of humidity in vertically-stacked dwelling unitsWetness and dryness in basementsConditions in the playroom compared to the bedroomAssessment of standard means of representationThis paper provides the analysis of three years of data. An earlier paper presented in Buildings IX provided the results from five months of data. The data are presented here in a format appropriate for comparison to other similar temperature and humidity data.
