The objective of this technical report is to define and present feedback on a remarkable indoor air quality (IAQ) management operation, through a reference framework of IAQ criteria in order to assess the inclusion of IAQ in school buildings.<\/p>\n

This reference framework was established as part of the task 3.1.2 of the 3SQAIR project, the deliverable of which can be downloaded from the project website www.3SqAir.com<\/p>\n

The approach has a dual objective:
\n– Improve stakeholder knowledge on how to manage IAQ in their own buildings.
\n– Propose a common methodology for comparative studies on \u201cbest practice\u201d case studies.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=\u00a0\u00bb1\/2″ vertical_content_position=\u00a0\u00bbmiddle\u00a0\u00bb]

One of the levers to achieve this objective is to share best practices (BP) with all stakeholders in order to enhance their knowledge, and consequently, their practices. To this end, we propose to identify the major action criteria to help stakeholders to improve IAQ in educational buildings.<\/p>\n

Our work consisted in drawing up a first state of the art of methodologies for assessing the IAQ in educational buildings. This first analysis made it possible to identify a list of IAQ improvement levers considering technical and organizational. And, we propose a simplified methodology assessing a synthesis profile of the IAQ for feedback from operations.<\/p>\n

In fact, the characterization of IAQ has many components, themselves linked to the complexity of the life cycle of a building. Such an analysis must be holistic because the IAQ of a classroom also depends on organizational aspects (maintenance and management of real estate), sociological (behavior and comfort of the occupants), economic (available resources) and even political considerations (exemplary public policies for contractors).<\/p>\n

We propose a baseline to define common criteria for promoting best practices in IAQ in classrooms, which also lays down common guideline settings for smart, sustainable and energy efficient IAQ solutions. Through a selective bibliographic study and an in-depth presentation of the modeling of IAQ pollutants, we have identified 10 major indicators for the inclusion of IAQ, classified into 2 areas:[\/vc_column_text]
