In order to estimate preconstruction airtightness in conventionally constructed homes, a local blower door testing population of 2297 homes was examined. Three builder-specific, geometric-based, temporally independent, multiple linear regression models were developed. Some of these builder-specific models explained over 58% (R = 0.79, p ≪ 0.001) of whole building airtightness. A five variable, geometrically based model which controlled for handicraft explained up to 74% (R = 0.87, p ≪ 0.001) of the whole building airtightness. The regression-based analyses on the local population suggested that air leakage is prominent through two building details: the floor-to-wall, and at the window-to-wall assemblies. While many comparable studies formulate airtightness models as a method to estimate post construction homes, this study demonstrated that preconstruction airtightness could be estimated with a temporally independent, builder specific, and geometrically-based method. Furthermore, this regression approach suggests that the methodology presented could be utilised as a design tool by members of the construction industry under a strict set of limitations.

为了估计常规建造房屋的施工前气密性，对当地2297户房屋的风机门测试人口进行了检查。开发了三个特定于构建器的，基于几何的，时间独立的，多个线性回归模型。一些这些助洗剂特定模型的解释超过58％（[R  = 0.79，p 整个建筑的气密性«0.001）。基于手工艺品的五变量基于几何的模型的解释率高达74％（R  = 0.87，p building 0.001）整个建筑物的气密性。对当地居民进行的基于回归的分析表明，漏气在两个建筑细节中很突出：地板到墙和窗户到墙的组合。虽然许多可比较的研究都将气密性模型公式化为估算建造后房屋的方法，但这项研究表明，可以使用时间上独立的，特定于施工人员且基于几何的方法来估算施工前的气密性。此外，这种回归方法表明，在严格的限制条件下，建筑行业成员可以将提出的方法用作设计工具。
