Day-and-night radiative sky cooling has emerged as a potential alternative to conventional technologies such refrigeration-based air conditioning and evaporative wet cooling. Both can passively achieve sub-ambient without consuming electricity. Although both techniques are subject impacts from various weather conditions, the extents of under same conditions not well understood. In this work, we...

The objective of this study is to design and analyse materials which are capable of harvesting water from thin air using condensation phenomenon which employs the radiative cooling approach. These passive cooling materials not only solve the water generating problems, but also employed in various cooling applications. The fundamental concept of radiative cooling is analysed and the performance ...

This paper presents a performance evaluation of two passive cooling strategies, daytime ventilation and night cooling, for a generic, six-story suburban apartment building in Beijing and Shanghai. The investigation uses a coupled, transient simulation approach to model heat transfer and airflow in the apartments. Wind driven ventilation is simulated using computational fluid dynamics (CFD). Occ...

The paper aims to investigate different measures of passive cooling that are compatible with existing buildings in order to reduce the energy consumption and peak demand associated with the cooling. Both the existing conditions and envisaged thermal comfort preference of the occupants of the building determine which retrofitting technology is most suitable in a particular case. Measures focusin...

Passive design responds to improve indoor thermal comfort and minimize the energy consumption. The present research analyzed the how efficiently passive solar technologies generate heating and cooling and provide the system integration for domestic applications. In addition to this, the aim of this study is to increase the efficiency of solar systems system with integration some innovation and ...

Passive radiative cooling has recently received renewed interest because of its unprecedented capabilities in terrestrial objects below ambient air temperature without external energy consumption and greenhouse gas emission. This technology been demonstrated as promising replacements/complements conventional compressed air-based active systems, which can significantly impact the global landscap...

OBJECTIVE Therapeutic hypothermia has become a standard neuroprotective treatment in term newborn infants following perinatal asphyxia. Active cooling with whole body surface or head cooling is complex, expensive and often associated with initial hypothermic overshoot. We speculated that passive cooling might suffice to induce and maintain hypothermia. METHODS We analysed 18 asphyxiated term ...
