Integration of high environmental quality comfort requirements during the retrofitting of educational buildings.

A important part of educational buildings must be retrofitted in many European countries, in the next years, for historical and demographic reasons. These retrofittings must be carried out with a limitation of energy consumption and a better indoor comfort. In this context, Annex 36 of International Energy Agency aims at promoting energy efficient measurements of educational buildings in the retrofitting process. In the same time, in France, decision makers want to integrate high environmental quality comfort requirements. These requirements are defined in order to better control external environmental impacts and to create a healthy and comfortable indoor environment. However, decision makers and designers have to make face to the complexity of the retrofitting of educational buildings and of the comfort notion. In order to integrate the acoustic, visual and thermal requirements, a specific approach must be developed. This paper exposes the high comfort constraints inherent in the retrofitting of educational buildings. Then an iterative integration process is presented within a study case in Rhne-Alpes Region.
