A Systematic Review of Outdoor Thermal Comfort Studies for the Urban (Re)Design of City Squares

Sustainability, Journal Year: 2024, Volume and Issue: 16(12), P. 4920 - 4920

Published: June 7, 2024

In the upcoming period, city squares’ urban redesign will be crucial in achieving sustainable development goals. This study presents a systematic review of OTC-related studies for design squares using PRISMA 2020 methodology. A included total 173 papers from 2001 to 2023. The results identified five types—clusters based on four pre-defined criteria: approach, data collection methods, time duration, and primary objectives. clusters indicate that more than half all are related comparison thermal comfort heat mitigation measures. Most case were located one three climate zones: temperate oceanic (Cfb) (58 studies), hot summer Mediterranean (Csa) (40 or humid subtropical (Cfa) (28 studies). most common geometry analyzed square is medium-sized, rectangular, has dominant axel orientation south–north. Also, clusters, several research gaps identified, appropriate future research: majority traditionally considered areas, no typology configuration OTC assessment, lack local model assessing improving squares.

Urban Resilience through Green Roofing: A Literature Review on Dual Environmental Benefits

E3S Web of Conferences, Journal Year: 2024, Volume and Issue: 536, P. 01023 - 01023

Published: Jan. 1, 2024

Urban areas face significant environmental challenges, notably rainwater management and the urban heat island effect. As sustainable ecological infrastructures, Green roofs provide dual benefits in addressing these issues. The literature review thoroughly explores how effective green are at boosting resilience by mitigating Heat Island effects enhancing stormwater control. Findings across various studies indicate that could significantly reduce surface ambient temperatures, with some reporting temperature reductions of up to 30 °C. Additionally, contribute retaining lseast 51% annual rainfall, thereby reducing runoff volume peak flow rates. By synthesizing data from 28 case worldwide, this highlights substantial offer settings. Our analysis suggests broader implementation further research into roof technologies essential for development. This paper calls increased integration planning leverage their benefits, particularly climate change impacts systems.

<p>Increased urbanisation has led to a worsening in the quality of life for people large cities due increase indoor temperatures. Retrofitted green roofs may attenuate housing temperatures, isolation and passive cooling properties these vegetated systems. For this purpose, research reports on an experiment using roof modular system compare outdoor temperatures before, after, set up existing depot Rio de Janeiro, Brazil characterized by high most parts year.

Nature-based solutions and buildings: A review of the literature and an agenda for renaturing our cities one building at a time

Nature-Based Solutions, Journal Year: 2023, Volume and Issue: 5, P. 100106 - 100106

Published: Dec. 24, 2023

A closer look at the built environment shows that opportunities lie in transforming buildings with nature-based solutions for fostering climate resilience. To understand potential of contributing to cities, we conducted a systematic literature review synthesize evidence provided benefits implemented on their roofs and facades. Our goal is highlight findings about co-benefits real-life case studies. After screening selection, 222 reviewed research papers support there confidence resilience performance green walls, roofs, living walls provide, heat indirectly social-ecological justice, especially when they are installed old buildings. show other recorded include provision vegetation, habitat biodiversity enhancement, strong water retention purification.

Evaluating Daily Water Stress Index (DWSI) Using Thermal Imaging of Neem Tree Canopies under Bare Soil and Mulching Conditions

Remote Sensing, Journal Year: 2024, Volume and Issue: 16(15), P. 2782 - 2782

Published: July 30, 2024

Water stress on crops can severely disrupt crop growth and reduce yields, requiring the accurate prompt diagnosis of water stress, especially in semiarid regions. Infrared thermal imaging cameras are effective tools to monitor spatial distribution canopy temperature (Tc), which is basis daily index (DWSI) calculation. This research aimed evaluate variability plant under different soil cover conditions through geostatistical techniques, using detailed thermographic images Neem canopies Brazilian northeastern region. Two experimental plots were established with cropped mulch bare conditions. Thermal leaves taken a portable camera processed Python language OpenCV database. The application technique enabled indicator mapping at leaf scale, spherical exponential models providing best fit for both results showed that highest levels observed during months air temperatures no rainfall, apex close central veins, due negative balance. Even extreme drought conditions, mulching reduced physiological leading lower associated higher moisture content skewness distribution. Regarding index, sequential Gaussian simulation method uncertainty variation surface. Our findings highlight Stress Index offers robust framework precisely detect agricultural management, as well management These underscore impact meteorological planting baseline be valuable regional resource managers diagnosing status more accurately.
