A Thermal Performance Detection Method for Building Envelope Based on 3D Model Generated by UAV Thermal Imagery

Abstract: The evaluation and renovation of existing building envelope has important practical significance for energy conservation and emission reduction in the field of architecture. With the development of digital cities, 3D models with rich temperature information can realize the comprehensive and accurate detection and evaluation of the existing building envelope. However, the 3D model reconstructed from thermal infrared images has only relative temperature distribution and no temperature value of each location, so … Show more

“…This example estimates global demand for electricity, and by the middle of the 21st century, global electricity consumption will be four times the total electricity consumption when the battery life of the 1970s. Since the oil crisis, global energy shortages have made commodity prices heavier, and more and more countries are estimating greater energy savings and consumption [3,4]. The concept of sustainable development is a viable answer to environmental and energy issues in the 21st century human development strategy [5].…”

“…The use of thermal mass in the building envelope can eliminate an extra 40% and 98% of total thermal discomfort time during the summer and winter seasons, respectively. Zheng et al (2020) evaluate the thermal performance of the building's entire envelope structure. They present a thermal infrared (TIR) external evaluation approach and devise a way to obtain TIR images of the building envelope using a UAV outfitted with an infrared camera and create a 3D point cloud model that includes temperature data for any specified locations.…”

“…These issues include monitoring of spontaneous fires in dry areas [24][25][26], pointing to places where warmer waters, including sewage, reach rivers and lakes [27], monitoring rainwater runoff in the city [28], estimating heat emissions in the area of geothermal lakes [11], imaging thermal variability of the lake surface [29,30], determining the thermal diversity of the upper forest area [31] or monitoring the life of wild animals [32,33]. Thermal imaging is widely used in construction to study the thermal integrity of buildings, which is important from the point of view of climate neutrality [13,[34][35][36]. In urban areas, thermal imaging is used to detect and track pedestrians in terms of their behavior [37].…”
