Une note de la Fabrique de la Cit\u00e9, publi\u00e9e d\u00e9but septembre 2026, analyse l\u2019impact des vagues de chaleur sur le patrimoine scolaire fran\u00e7ais et les besoins d\u2019adaptation au changement climatique. L\u2019\u00e9t\u00e9 2026 a conduit \u00e0 la fermeture de plus de 1 800 \u00e9tablissements scolaires et \u00e0 l\u2019adaptation des horaires dans 8 000 \u00e9tablissements lors des \u00e9pisodes caniculaires. Le parc concern\u00e9 est tr\u00e8s \u00e9tendu : 64 000 \u00e9tablissements accueillant quotidiennement 13 millions de personnes, repr\u00e9sentant pr\u00e8s de la moiti\u00e9 du patrimoine immobilier des collectivit\u00e9s territoriales.<\/p>\n
La note souligne que 80 % des \u00e9coles ont plus de 50 ans et qu\u2019environ un \u00e9tablissement sur deux n\u00e9cessiterait une r\u00e9novation lourde, ces b\u00e2timents ayant \u00e9t\u00e9 con\u00e7us pour des conditions climatiques qui ne correspondent plus au climat actuel. Elle rappelle que le troisi\u00e8me Plan national d\u2019adaptation au changement climatique (PNACC) s\u2019appuie d\u00e9sormais sur une trajectoire possible de +4 \u00b0C \u00e0 l\u2019horizon 2100, ce qui rend la probl\u00e9matique de l\u2019adaptation du b\u00e2ti scolaire particuli\u00e8rement structurante pour les politiques publiques.<\/p>\n
Le co\u00fbt de r\u00e9novation des seules \u00e9coles publiques est estim\u00e9 par la Fabrique de la Cit\u00e9 \u00e0 pr\u00e8s de 50 milliards d\u2019euros sur dix ans. L\u2019\u00e9tude souligne toutefois qu\u2019une strat\u00e9gie fond\u00e9e exclusivement sur la r\u00e9novation lourde se heurte \u00e0 des contraintes financi\u00e8res et op\u00e9rationnelles importantes : actuellement, seuls 2 600 \u00e9tablissements par an engagent des travaux \u00e9nerg\u00e9tiques et \u00e0 peine 10 % des \u00e9coles disposent d\u2019un projet de r\u00e9novation formalis\u00e9.<\/p>\n
La note met en avant des mesures d\u2019adaptation plus rapides et d\u00e9j\u00e0 document\u00e9es, telles que protections solaires, volets, films ou voiles d\u2019ombrage, ventilation nocturne, brasseurs d\u2019air ou v\u00e9g\u00e9talisation. Exp\u00e9riment\u00e9es dans le cadre du programme Racine, ces solutions auraient permis de r\u00e9duire la temp\u00e9rature int\u00e9rieure jusqu\u2019\u00e0 10 \u00b0C dans certaines salles de classe, pour un co\u00fbt compris entre 20 000 et 100 000 euros par \u00e9tablissement. Ces \u00e9l\u00e9ments posent la question de la hi\u00e9rarchisation des investissements entre r\u00e9novations lourdes et interventions plus l\u00e9g\u00e8res mais rapidement d\u00e9ployables, dans un contexte de forte contrainte budg\u00e9taire des collectivit\u00e9s.<\/p>\n
La Fabrique de la Cit\u00e9 insiste \u00e9galement sur l\u2019effet du choc d\u00e9mographique sur la planification du parc scolaire. Elle rappelle que la France pourrait compter 1,7 million d\u2019\u00e9l\u00e8ves en moins d\u2019ici 2035, ce qui interroge le dimensionnement futur des infrastructures \u00e9ducatives et complique les arbitrages locaux : investir massivement dans l\u2019adaptation climatique de b\u00e2timents alors m\u00eame que les besoins en capacit\u00e9 d\u2019accueil devraient diminuer. Cette double contrainte \u2013 acc\u00e9l\u00e9ration de la chaleur extr\u00eame d\u2019une part, baisse attendue des effectifs d\u2019autre part \u2013 est pr\u00e9sent\u00e9e comme un \u00e9l\u00e9ment central pour la strat\u00e9gie des collectivit\u00e9s territoriales et la mise en \u0153uvre des politiques d\u2019adaptation dans le champ scolaire.\u00a0(contenu r\u00e9sum\u00e9 par l’IA)Lire la Suite<\/a><\/p>","protected":false},"excerpt":{"rendered":" Une note de la Fabrique de la Cit\u00e9, publi\u00e9e d\u00e9but septembre 2026, analyse l\u2019impact des vagues de chaleur sur le patrimoine scolaire fran\u00e7ais et les besoins d\u2019adaptation au changement climatique.
