Background and Objective: Environmental quality of housing is a part of health protection. It combines reduced exposures to pollutions and access to available resources for protection and care services. In France, many local authorities lack of financing capacities or political will to improve housing, except for tourism (hotels, etc.) a key for local economy development. We developed a tool (Reveleo) able to check the environmental quality of the housing and applied it to tourism facilities (hotels, guest houses…) to check the feasibility and acceptability of both tourism holders and local authorities. Methods: Reveleo combines open sources data (ie exposure to air polluting, noise,…) from French Governmental agencies and a questionnaire dedicated to the quality of buildings and close environment. We have tailored the questionnaire so that to clarify health issues and make it fillable by any tourism holder. We tested it, in an urban and rural area of 17000 inhabitants and also checked how it could match the question of tourism development policies. Results: Among the 18 tourism holders, 10 answered. Hotel holders did not answer mainly due to the lack of employees they had to face. All the questionnaires were fulfilled, with 78% of the items answered. The scoring for quality of environmental housing goes from 18,6 to 100 (the best possible score). We presented the results to the technical and political staffs of the area which decided to continue the experiment and were able to see the kind of actions they can take. Conclusions: We need to make some improvement to our tool, for answers difficult to get. But, for now, its feasibility and acceptability are good, and there are good hopes that it will help improve or build better healthy environment policies.
