Abstract

This paper presents a study of the thermal performance and occupant satisfaction of naturally ventilated earth houses during a hot summer period. An earth house community located in Santiago, Chile, was chosen as a case study. Building Use Studies (BUS) survey was used to understand the general satisfaction and thermal comfort of users living in earth buildings. In parallel, two occupied houses constructed with wattle and daub techniques were monitored. Occupants highly rated most aspect of the house, yet thermal related variables are less satisfactory. The monitored results showed that indoor diurnal temperatures in both houses have differences between 15-20°C compared with outdoor temperatures. The indoor temperature of adobe bedroom showed a more drastic deviation when the outdoor temperature was lower than 20°C. This study has verified the thermal comfort potential of earthen constructions, notably contributing to indoor temperatures in summer.
