The “VIA-Qualité” project (2013-2016) aims at developing quality management (QM) approaches (ISO 9001) on ventilation and indoor air quality (IAQ), for low-energy, single-family buildings. The goal of these QM approaches is to improve both ventilation and IAQ actual in-situ performance. The main benefits of those approaches are to: 1-Improve ventilation system performance from design to implementation; 2-Limit indoor internal pollution sources, monitoring building materials selection and design regarding the outdoor pollution sources; 3-Improve final users understanding.
The first part of the paper is dedicated to the presentation of the schemes developed to help builders implement quality management approaches on ventilation and IAQ. The quality management approaches structuration led to the development of key tools. The first QM tool presents the main steps, processes and documents that should be implemented by a single-family house builder. The second QM tool is composed of technical drawings for the workers. The third QM tool, dedicated to the final user, aims at raising awareness on ventilation system maintenance and IAQ.
The second part of the paper presents the evaluation of the QM approach implementation by two French builders on 8 houses. We measured ventilation and IAQ performance at commissioning and measured results are disappointing. However lessons learnt are positive. The results focus on the implementation and the feedback on these approaches on the success factors or barriers to apply them, including training evaluations.
The paper concludes on lessons learnt by the development and the application of quality management approaches on ventilation system and IAQ and proposes some hints to implement such approaches.
