Monitoring and Investigation Challenges in Heritage - Buildings

This document discusses the role of sensors and instruments in monitoring heritage buildings and addressing conservation challenges at the National Trust. Routine monitoring helps identify building defects, energy losses, and pipework conditions. Thermography surveys detect heat losses and timber decay. Research monitoring measures surface temperatures and structural responses. Sensors investigate deteriorating wall paintings, salt efflorescence, fragile ceilings, and the effects of vibration on wall paintings. Future monitoring needs include roof gutter drainage, masonry moisture content, and evaporation from masonry.
