NEMESYS – Accelerating the Zero-Energy Cooling Revolution
Next-generation AI-powered fraMEwork for radiative cooling SYStems design, optimisation and market uptake
An intelligent digital environment featuring an AI-assisted decision-support tool that helps designers select and deploy radiative cooling materials for real-world applications — enabling rapid optimisation and market uptake.
Cooling demand is rapidly becoming one of the fastest-growing global energy challenges. By 2050, it is projected to more than triple, driven by urbanization, rising temperatures, and the expanding middle-income populations in warmer regions. This increase in cooling demand will lead to higher electricity consumption, put pressure on power grids, and heighten heat-related health risks. Buildings already account for 40% of global energy use and 30% of CO₂ emissions, making sustainable cooling a critical priority for both climate mitigation and energy security. Selective passive daytime radiative cooling (sPDRC) materials are acknowledged as the most promising
mitigation strategy. By reflecting solar radiation while emitting heat through the atmospheric window toward outer space, these materials can cool surfaces below ambient temperature without energy input. Despite rapid scientific advances and growing industrial interest, market adoption remains limited due to the absence of reliable, standardised tools to quantify and compare cooling performance across
climates and real buildings.
NEMESYS addresses this gap by translating the ERC StG HELIOS main results into an intelligent digital environment featuring an AI-assisted decision-support tool for the standardised and context-aware evaluation of sPDRC materials.
By combining physics-based modelling, validated material datasets, and AI-assisted analysis, NEMESYS Hub enables reliable benchmarking, supports certification and design workflows, and reduces time-to-market for new cooling techs. Through
collaboration with manufacturers and international networks, the project validates the Hub and accelerates market uptake of next-generation zero-energy cooling solutions.
