The conscious shift to sustainable practices in the built environment provides significant contributions to reduction in environmental pollutants. Heritage buildings due to design consideration, material availability and preservation guidelines are huge potentials for sustainability exploration. Unmanned aerial vehicle (UAV) captures heritage building data with less intrusion to building use. Currently, traditional 2D drawings and site visit form the basis for sustainability decisions which makes the process cumbersome and, in some cases, missing building drawings and lack of digital tools further compounds this process. Therefore, this study aims to leverage UAV from a sustainability assessment approach to develop maintenance plan for heritage buildings. Simulation based methodological approach was adopted in this study. UAV flight mission and deployment time were designed to meet the heritage site. Thermal imaging camera was modified into UAV for external thermal data. Handheld moisture meter was used in capturing internal moisture readings. The results revealed thermal images from external and internal moisture aligned in assessment of the roof condition. The sustainability analysis presented a significant savings in electricity consumption by orientation of solar panels and water collection. The results directly impact decision making by policy makers for improvements in sustainability maintenance in heritage building.
