本文介绍了一项参与性行动研究项目的第一阶段所获得的结果和关键信息，该项目由5家开发商开展，旨在调查在改进投机建造的主流住房的气密性时出现的实际设计和施工问题。在项目中有两种建筑类型，砖石腔和轻钢框架。第一期工程旨在详细评估25间住宅的设计、建造及透气性，以符合2002年批准文件第L1部分的规定。虽然这里报告的住宅总数很少，但结果表明，开发商向现场人员提供空气泄漏信息的方式并不一致，现场使用了多种方法来达到相同的规范，并且在详细设计阶段似乎缺乏远见，导致规范实际上很难实现。尽管如此，透气性结果表明，采用湿抹灰/机械抹灰内部饰面的住宅可以默认达到英国标准的合理气密性标准，而无需额外注意气密性。
This paper presents the results and key messages that have been obtained from Phase 1 of a participatory action research project that was undertaken with 5 developers to investigate the practical design and construction issues that arise in making improvements to the airtightness of speculatively built mainstream housing. Two construction types were represented in the project, masonry cavity and light steel frame. Phase 1 of the project sought to assess in detail the design, construction and air permeability of 25 dwellings that were constructed to conform to the requirements of Approved Document Part L1 2002. While the total number of dwellings reported here is small, the results suggest that there is not a consistent approach to the way in which developers present information on air leakage to those on site, a mixture of approaches are utilised on site to achieve the same specification and there appears to be a lack of foresight in the detailed design stage, resulting in specifications that are practically very difficult to achieve. Despite this, the air permeability results suggest that dwellings constructed with a wet/mechanically plastered internal finish, can default to a reasonable standard of airtightness by UK standards, without much additional attention being given to airtightness.
