A comparative study of energy performance of Green, White, and gravel roofs in a temperate climate through In-Situ measurement and dynamic simulation

Green roofs with grass vegetation effectively reduce heat flow and total energy consumption, while sedum vegetation is the most effective for passive cooling in temperate climates.

Effectiveness of Cool and Green Roofs Inside and Outside Buildings in the Brazilian Context

Cool roofs reduce electricity consumption by up to 24.8% in warmer Brazilian cities, while green roofs are more effective in colder climates, with both providing hourly reductions in outside surface temperature.

Numerical simulation of a pioneering cool roof system for Asia's roofing system reformation: The alternative cooling measure

The cool roof system, composed of white reflective coating, hollow foamed concrete roof tile, and sustainable active reflective insulation, effectively reduces heat flux and energy-saving performance by 27.5 percent in tropical climates.

Experimental study of the thermal insulation performance of phase-change ventilated roofs

The new phase-change ventilated roof, combining energy storage, ventilation, and solar power generation, significantly improves thermal insulation and energy efficiency compared to traditional roofs.

Investigation of used PCM-integrated into building exterior walls for energy savings and optimization of PCM melting temperatures

Using three-layer BioPCM27 integrated exterior walls with a melting temperature of 21°C provides the highest heating energy savings (21.32%) on an annual basis, while the three-layer (3L) InfiniteRPCM21C configuration (Type 3) provides the best thermal energy performance.

Analysis of thermal energy storage tanks and PV panels combinations in different buildings controlled through model predictive control

Thermal energy storage tanks provide shorter payback periods than PV panels, but PV panels can achieve up to 34%, 54%, and 90% reduction in electricity grid consumption in Helsinki, Strasbourg, and Athens.
