Energy consumption in buildings represents about 40% of the total annual energy usage in
the EU. With greater awareness of the need to reduce energy consumption comes a growth
of interest in passive cooling, particularly as an alternative to air-conditioning. Drawing ...

Matter continuously exchanges energy with its surroundings. This exchange can be
dominated by radiation, conduction, or convection. In this brief review we discuss how
proper design of radiative surface properties can be used for heating and cooling ...

Calculations of spectral radiance are reported from several model atmospheres appropriate
to different climatic conditions by use of the LOWTRAN 5 computer code. From these data
we evaluate the radiative cooling power and the temperature drop below ambient ...

Abstract The performance of panels which cool by. means of thermal infrared heat transfer to
the sky is calculated from basic principles. The efficiency of a radiative cooling panel is
defined. Computer calculations with the full heat transfer equations are performed for ...

abstract Plastic foils containing nonabsorbing pigments can display a high reflectance of
solar radiation combined with a high transmittance in the atmospheric window region in the
thermal infrared. Such foils can be applied as selective covers enabling radiative cooling ...

Abstract The cooling of small buildings at night by radiation loss to the sky has been
investigated by monitoring the thermal performance of two huts: one roofed with galvanised
steel decking painted white, which acts as a 'black body'for wavelengths greater than 3 μm ...

A radiative cooling system is built in Irbid-Jordan and utilized to cool and store fluids by
direct radiation to the low effective sky temperature. The radiative cooling system is built to
verify the validity of a mathematical model proposed to describe the system dynamic ...

abstract A brief survey is given of some recent trends and developments in the field of optical
coatings for energy efficiency and solar applications. The discussion is focused on spectrally
selective coatings and embraces transparent heat-mirrors, surfaces for selective ...

Abstract The thermal performance of an uncovered radiator and a radiative cooling system
was investigated experimentally and theoretically. The net radiative power of a black painted
surface at ambient air temperature was measured by heat flux plates at night in order to ...
