Architecture in HVAC

The “Green Olympics” theme of the 2008 Olympic Games in Beijing, requires that all construction of venues and facilities must meet environmental and energy-efficiency standards. The bird’s nest was designed to meet Gold-LEED certified building standards. To construct a sustainable building of this magnitude, it is crucial that the HVAC system have a strong sense of environmental sustainability. The stadium’s roof is a big part of its sustainability; the original retractable roof design would have required artificial lighting, ventilation systems, and increased energy loads. The open roof allows for natural air and light to enter the structure, and the translucent roof adds much needed light as well. The stadium is able to control its temperature naturally using advanced geothermal technology that gathers hot and cold air from the stadium’s soil.

Beijing is located near one of the most seismically active locations on earth. For this reason, the design required an HVAC infrastructure based on a pipework system that was flexible and simple to install at the required angles. The Victaulic grooved joint system consists of a housing coupling, a bolt, a nut and a gasket. This customizable pipework solution provides flexible couplings, so the HVAC pipes could be installed at any of the different angles to meet the various deflection requirements of the Bird’s Nest.

Victaulic is also essential in protecting the stadium’s piping system from seismic activity, wind and other earth movements common in China. Beijing Olympic Committee members and contractors specified Victaulic mechanical pipe joining systems for the stadium’s HVAC system with these geological factors in mind. As an added benefit, these particular piping systems aided in keeping up with a tight construction schedule, due to their easy installation requirements. Beijing is located in a warm temperature zone with a continental climate and moderately short seasons. Therefore, the HVAC system in this instance was designed to address sustainability and other environmental needs rather than any drastic climate change.
