The annex was formed to address energy issues related to low slope roof systems. The first task undertaken was the development of a sourcebook on good practices for design, installation and maintenance of insulated roof systems. The intent of the sourcebook is to provide a discussion of both real and perceived correlations between roof systems and to present information on recent roofing issues that have insulation implications. Annex members have identified and reviewed a list of 25 potential correlations between roof problems and insulation.

Within the framework of the work of Annex 25 of the International Energy Agency, the CSTB, in collaboration with different French research teams, is setting up a research programme on the methods of fault detection and diagnosis applicable to heating, ventilating and air conditioning systems (HV AC systems).
