Swallow birds (Collocalia fuciphaga) are found in many islands in Indonesia. In general, swallows like sites which are warm and humid for their house and making nests. Swallow’s nest is a product of high economic value. Many people are interested in building houses for swallow to gain profit from the nest. The aim of the study is to describe the thermophysical characteristics of building materials of the house, and its indoor air temperature. The methodology used is descriptive analysis. The study includes measurements of outdoor and indoor climate variables which are air temperature, surface temperature and humidity. Identification of thermophysical material include heat specific capacity, thermal conductivity and density of wall and roof material. The results of climatic measurements carried out on 7 and 8 May 2021 in Minahasa showed that the indoor temperature was in the range of 25 to 27 °C, and relative humidity of around 84 to 85 %. Geometric and thermophysical modelling were made for simulation calculations by using HEAT2 software. The calculation results show that the distribution of indoor air temperature is in range of 25.6 to 25.8 °C, where in average there is a difference of about 0.5 °C lower than the measurement results.
