Dual‐Band Electrochromic Smart Window for Dynamic Switching Between Radiative Cooling and Solar Heating

open access: yesAdvanced Science, EarlyView.
In this study, an electrochromic glass is designed by effectively integrating silver electrodeposition with mechanical flipping of the glass panel, enabling bidirectional dynamic regulation of the solar and mid‐infrared spectra. Its capability to dynamically switch between radiative cooling and solar heating modes offers substantial energy‐saving ...

Humidity‐Controlled Smart Window with Synchronous Solar and Thermal Radiation Regulation

open access: yesAdvanced Science, EarlyView.
A humidity‐responsive PTFE/PVA composite membrane with a nanoporous structure is developed and integrated between double glazing for the construction of smart windows. By modulating the interlayer humidity levels, this system achieves dynamic solar modulation (54.4%) and thermal radiation modulation (51.4%) via reversible water vapor adsorption ...

Assessment of Pollutant Spread from a Building Basement with three Ventilation Systems [PDF]

open access: yesEuroAcademy on Ventilation and Indoor Climate - CLIMACADEMY Course 7: Experimental Assessment of Indoor Environment Parameters, Pamporovo : Bulgaria (2009), 2010
Ventilation aims at providing a sufficient air renewal for ensuring a good indoor air quality (IAQ), yet building energy policies are leading to adapting various ventilation strategies minimising energy losses through air renewal. A recent IAQ evaluation campaign in French dwellings shows important pollution of living spaces by VOCs such as ...
