Performance evaluation of a metamaterial-based new cool roof using improved Roof Thermal Transfer Value model

open access: yesApplied Energy, 2019
A new cool roof with potential to generate significant energy savings in buildings has been developed from a metamaterial film named as RadiCold. Considering that the RadiCold film has unique optical and thermal characteristics and the current Roof ...

Optimization of cool roof and night ventilation in office buildings: A case study in Xiamen, China [PDF]

open access: yesRenewable Energy, 2020
Increasing roof albedo (using a “cool” roof) and night ventilation are passive cooling technologies that can reduce the cooling loads in buildings, but existing studies have not comprehensively explored the potential benefits of integrating these two ...

Thermal Effects of Dew on Cool Roofs and Conventional Roofs in Building Performance Simulations

Energy and Buildings, 2022
This paper presents a numerical investigation of dew formation on the roofs of buildings, and its influence on building thermal and energy performance. A new semi-analytical model was developed to evaluate the effects of rooftop dew, including the release/absorption of latent heat due to condensation/evaporation, the variation of apparent thermal ...

Radiative cooling by a diode roof

Solar & Wind Technology, 1986
Abstract The research of thermal comfort in buildings has always been a preoccupation for people. In hot regions, generally, the problem to solve, in order to enjoy thermal comfort, is effective cooling. Architecture evolution in the last few years, in hot and arid regions, and particularly in the Third World, dictates that cooling systems in ...

What’s Up On The Roof: Tracking Cool Roofs in India with Satellite Imaging

ACM Journal on Computing and Sustainable Societies
With rapid pace of urbanization, the increase in built up area is leading to urban heat islands which absorb a lot of the heat received through solar radiation. To reduce this effect, reflective coatings on top of building roofs, known as cool roofs are installed.

Cool Roofs vs Solar Systems

Applied Mechanics and Materials, 2016
Well known problem of urban heat island is partly due to the albedo of traditional roofs. Mostexperts of urban climate are convinced that the intensity of urban heat island will be less if theroofs reflect as big part of the solar radiation as possible.

On the analysis of cool roofs for cooling system efficiency

2013
Cool roof is a well-documented passive cooling strategy for buildings in several climate conditions. The mechanism consists of the reduction of the heat load entering the roof, which is characterized by high solar reflectance and high thermal emittance. The purpose of this paper is to study the coupled effect produced by such a technology.

Cool materials and cool roofs: Potentialities in Mediterranean buildings

Advances in Building Energy Research, 2010
Abstract The Mediterranean is a complex region, with differences in terms of environmental hazards, population growth, urban sprawl and economic development. The climate change affects all of the area and common risks are already detected. An urban heat island was monitored in a large and medium urban area.

Assessment of green roof cooling performance and operational carbon potential based on roof cooling unit

Sustainable Cities and Society
Cities face dual responsibilities of decarbonization and resilience building under climate change, yet high-density urban areas have limited space for interventions. Green roofs (GR) offer a synergistic strategy, but their decarbonization benefits from spatial cooling are often assessed by “black-box” simulations: models that offer low controllability ...
