Displacement ventilation systems
Introduction
Linked Hybrid is a building complex located in Beijing, China, designed by Steven Holl Architects. It was built between 2003 and 2009 and contains 644 apartments. It was recognized for its environmental design and use of geothermal wells for cooling and heating. Linked Hybrid has won several awards, including Best Tall Building in the World by the Council on Tall Buildings and Urban Habitat in 2009.
It was designed as a pedestrian-oriented combination of public and private spaces that encourages the use of shared resources and reduces the need for polluting modes of transportation.
Construction
Linked Hybrid was built between 2003 and 2009. It has about 2,500 inhabitants.[3].
Sustainable design
Linked Hybrid's geothermal heat pump system accounts for 70% of the building's annual cooling and heating expenses. This system consists of 655 geothermal wells, 100 meters below the foundation. These underground wells have replaced the space necessary for cooling towers, increasing green areas, reducing noise and CO emissions generated by traditional methods.
Linked Hybrid uses a technique called displacement ventilation, which involves releasing air slightly below the desired temperature into the room from the floor. This cold air displaces the hot air, causing it to be expelled from the room and achieving a lower temperature and a fresh environment.
