IR Thermography for the Restoration of Colonial Architecture in India—Case study of the British Residency in Hyderabad, Telangana

tInfrared Thermography (IRT) has been a non-destructive and economical method for identifying potentialproblems in buildings. Passive thermography tracks the thermal patterns in structures caused due toexposure to solar radiation. Interpretation of results for the Passive approach is highly dependent onunderstanding of the surrounding environmental conditions of the building being surveyed. However,existing literature and scientific research on the subject focuses on buildings in Europe and NorthernAmerica. These conditions have not yet been established for the Indian Sub-Continent as there have beenno studies that identify the methodologies for this yet. There have been a few studies on the use of IRT forheritage buildings in India. Nevertheless, they do not explain the environmental conditions during thethermal survey, which might affect the interpretation of the thermal images produced. This project aimsto elucidate more about the way IRT works in conditions that are sometimes less than optimal, throughthe case study of the Former British Residency in Hyderabad.
