Over 100,000 houses were built following the devastation caused by the Tsunami of December 26, 2004. Here the authors investigated thermal comfort in housing built in Banda Aceh, Indonesia, following the widespread destruction of buildings and compared it with undamaged existing houses and a traditional Acehnese house. The study is based on a field survey, questionnaires, and performance simulations. The findings show no significant difference between the post-tsunami housing and the unaffected existing housing, except traditional Acehnese houses which generally performed better. © 2013 IAHS.
