Rain On The Roof-Evaporative Spray Roof Cooling

open access: green, 1985
This paper describes evaporative spray roof cooling systems, their components, performance and applications in various climates and building types. The evolution of this indirect evaporative cooling technique is discussed. Psychrometric and sol-air principles are covered and a simplified method of evaluation presented.

Interaction of urban heat islands and heat waves under current and future climate conditions and their mitigation using green and cool roofs in New York City and Phoenix, Arizona

open access: yesEnvironmental Research Letters, 2019
Urban environments and heat waves interact synergistically and aggravate the thermal environment through the urban heat island (UHI) effect. Of concern is the potential for a projected warmer future climate to further compound heat waves in urban ...

Economic comparison of cool and grey roofs of a small office building in the USA [PDF]

open access: yesSHS Web of Conferences, 2023
EnergyPlus V9.0 simulations of a typical small office building prototype in five USA cities (Albuquerque, Atlanta, Buffalo, San Diego, Rochester) indicate that adding a cool roof (albedo 0.6) for an aged grey roof (albedo 0.2) would reduce the annual ...

Thermal performance analysis of near infra-red reflection and green roof cooling techniques on buildings made of mild steel

open access: yesRenewable Energy and Environmental Sustainability, 2023
This paper investigates the thermal performance of green roofs, cool roofs, and their combined effects in tropical climates. Although each technology has been studied independently for its potential to reduce cooling energy consumption in buildings ...

Energy consumption and heat island effect mitigation analysis of different roofs considering superposition coupling

open access: yesFrontiers in Energy Research, 2023
Building energy, particularly air conditioning energy, makes for a significant fraction of overall societal energy usage. The heat island effect is a common urban environmental concern that threatens human sustainable development. Roofs, which cover more

Comparing PV-green and PV-cool roofs to diverse rooftop options using decision analysis

open access: yesBuilding and Environment, 2023
Flat roofs can employ a range of technologies to improve sustainability, such as photovoltaic (PV) panels, green roofs, cool roofs, or a combination of these options. Yet, weighing the benefits, costs, and performance of different roofing technologies is

Experimental analysis of energy consumption of building roof energy-saving technologies based on time difference comparison test

open access: yesFrontiers in Energy Research, 2023
The roof plays a pivotal role as it directly engages with solar radiation absorption and external heat exchange, significantly influencing the building’s overall energy dynamics. To assess the performance of green roofs and cool roofs, a roof performance

Cool Roofs in Hot Climates: A Conceptual Review of Modelling Methods and Limitations

open access: yesBuildings, 2022
Cool roofs are a long-term alternative for the creation of a building’s thermal comfort as they can reduce the energy required for cooling demands and mitigate the urban heat island effect, thus benefitting both buildings and cities.
