Bioclimatic Architecture Strategies in Denmark: A Review of Current and Future Directions

open access: yesBuildings, 2022
Due to climate change, the rise in global temperature causes an increased need for cooling to satisfy occupants’ thermal comfort. Application of architecture passive design strategies, so-called bioclimatic architecture strategies, based on the local ...

Passive Cooling of Surfaces

open access: yesScientific Inquiry and Review, 2018
Radiative cooling of surfaces without applying an energy source has been suggested in the literature. The basis for radiative cooling is the infrared transmittance of the atmosphere. The spectral transparency (i.e. low absorption) of the atmosphere in the wavelength range of 8 to 13 μm is generally termed the atmospheric window.

A macroscopic object passively cooled into its quantum ground state of motion beyond single-mode cooling

open access: yesNature Communications, 2021
Compared to active techniques, passive cooling of mechanical modes allows to work with devices in equilibrium with their environment without excess damping. Here, the authors demonstrate passive cooling and thermalisation of a 15 μm drum-head device with

Technical solutions to prevent heat stress induced crop growth reduction for three climatic regions in Mexico [PDF]

open access: yes, 2008
In the last 15 years a significant increase in greenhouse area has occurred in Mexico, from a modest 50 hectares in 1990 to over 2,000 hectares in 2004. The rapid increase in greenhouse area is a result of an attractive export market, USA. Mexican summer
