Abstract
The dampness is a significant threat in the heritage building and a leading factors to the degradation and dilapidated building. The scientifically measured need to be implemented in mitigating such issues. Advance understanding of heritage building condition is a must in mitigating to prolong the building life cycle. The study purpose is to measure surface temperature, ambient temperature and relative humidity at the dampness point of the heritage building. The measurement calculation technically reveals the dew point temperature and indicates the prediction of thermal bridge and mould risk. In situ test conduct using natural infrared heat radiation to the same relevant surface. The preliminaries finding indicates the average temperature pattern at the surface in four (4) heritage building with nineteen (19) spot at (24.5-25.7)°C, dew point temperature (23.7-24.3)°C, ambient temperature (25.78-27.0)°C and relative humidity (85.5-89.6)%. The preliminaries finding leads to the identification of no thermal bridge treat but with highly mould risk.
