Roof Color-Based Warm Roof Evaluation in Cold Regions Using a UAV Mounted Thermal Infrared Imaging Camera

open access: yesEnergies, 2021
Existing studies on reducing urban heat island phenomenon and building temperature have been actively conducted; however, studies on investigating the warm roof phenomenon to in-crease the temperature of buildings are insufficient.

Improved Mask R-CNN for Rural Building Roof Type Recognition from UAV High-Resolution Images: A Case Study in Hunan Province, China

open access: yesRemote Sensing, 2022
Accurate roof information of buildings can be obtained from UAV high-resolution images. The large-scale accurate recognition of roof types (such as gabled, flat, hipped, complex and mono-pitched roofs) of rural buildings is crucial for rural planning and

Productive Blue-Green Roofs for Stormwater Management

open access: yesGreen Energy and Environmental Technology, 2022
Green roofs have been used around the world for centuries, and have been adapted to modern urban buildings. Many cities have now adopted a green roof bylaw in recognition of their environmental benefits, including stormwater management. Despite this requirement, if green roofs are poorly designed, they may quickly become ineffective or ...

Evaluation of Applicability of Various Color Space Techniques of UAV Images for Evaluating Cool Roof Performance

open access: yesEnergies, 2020
Global warming is intensifying worldwide, and urban heat islands are occurring as urbanization progresses. The cool roof method is one alternative for reducing the urban heat island phenomenon and lowering the heat on building roofs for a comfortable ...

“Cool” Roofs as a Heat-Mitigation Measure in Urban Heat Islands: A Comparative Analysis Using Sentinel 2 and Landsat Data

open access: yesRemote Sensing, 2022
Urban growth, characterized by expansion of impervious at the cost of the natural landscape, causes warming and heat-related distress. Specifically, an increase in the number of buildings within an urban landscape causes intensification of heat islands ...
