Influence of site dependent effects on the assessment of the radiative cooling potential

Abstract

The assessment the radiative cooling potential requires the knowledge of some site dependent boundary conditions affecting to the performance of the respective technological systems. These boundary conditions are mainly related to the existence of certain climatological solicitations that will determine the feasibility or not for each application. This paper presents a contribution to a more accurate assessment of the radiative cooling potential based on the analysis of the influence in the estimation of effective sky temperature and effective sky temperature depression of local or transient effects associated to the existence of a non standard vertical atmospheric structure. These eventual deviations are usually not considered in the conventional estimation models, based exclusively on surface information, and the suitability of the proposed approach is established by comparison with measured data.
