Metrological framework for passive radiative cooling technologies
Annotation in Czech
The overall goal of this project is to establish a metrological framework for comparable performance assessments of passive radiative cooling (PRC) materials. The specific objectives of the project are: 1. To develop the conceptual framework for comparable performance assessments of passive radiative cooling technologies. 2. To develop and validate numerical models to correlate the cooling performance of PRC materials with the thermal and optical properties of their components, and thus to establish their specifications and associated tolerances. 3. To develop accurate and traceable approaches for determining the thermophysical properties and thermal conductivity of PRC materials, and for converting measured radiometric quantities into a usable form for heat balance calculations. The reflectance and emittance will cover a broad spectral range (0.25 μm – 50 μm) encompassing the solar spectrum and the infrared transparency window of the atmosphere (8 μm – 13 μm). The target uncertainties will be below 3 % for emissivity and absorptivity, 5 % for the total hemispherical emissivity and 10 % for the thermal conductivity (WP3). 4. To develop setups and protocols for on-site testing of PRC materials, with a target uncertainty below 10 % for the figures of merit (WP4). 5. To facilitate the take up of the technology and measurement infrastructure developed in the project by the measurement supply chain (testing laboratories), standards developing organisations (CEN/TC 89) and end users in the commercial and residential sectors (WP5).
