Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption. [ 1 ] [ 2 ] This approach works either by preventing heat from entering the interior (heat gain prevention) or by removing heat from the building ...
Passive cooling is the use of similar design principles to reduce summer cooling requirements. Some passive systems use a small amount of conventional energy to control dampers, shutters, night insulation, and other devices that enhance solar energy collection, storage, and use, and reduce undesirable heat transfer.
This solar chimney draws air through a geothermal heat exchange to provide passive home cooling. [2] [3]Solar chimneys, also called heat chimneys or heat stacks, can also be used in architectural settings to decrease the energy used by mechanical systems (systems that heat and cool the building through mechanical means).
Use of passive natural ventilation is an integral component of passive house design where ambient temperature is conducive—either by singular or cross ventilation, by a simple opening or enhanced by the stack effect from smaller ingress with larger egress windows and/or clerestory-operable skylight.
A lot, of course, comes down to energy savings. A Passive House project, said Klingenberg, uses between 50 to 80% less energy than a typical building, depending on variables like size and location.
This research focused on a film developed for hybrid passive cooling. The film uses sodium polyacrylate, a low-cost industrial material, to achieve high solar reflectance and high mid-infrared emittance. A significant feature of this material is its ability to absorb atmospheric moisture, aiding evaporative cooling. This tripartite mechanism ...
Passive solar cooling is much easier to achieve in new construction than by adapting existing buildings. There are many design specifics involved in passive solar cooling. It is a primary element of designing a zero energy building in a hot climate.
