On the basis, a multi-objective genetic optimization algorithm is utilized to improve the support strength of wind environment simulation to a natural ventilation design decision making process in a gymnasium space form design process. The cold region gymnasium building natural ventilation parameterized simulation optimization design method mainly comprises the steps that buildinggeometrical information and environment boundary condition information are integrated; building a corresponding relation between the building space form optimization parameters and the natural ventilation performance target; and three steps of ventilation and thermal comfort multi-performance target optimization guide search are carried out.

Description

Technical field [0001] The invention relates to the technical field of building energy-saving passive design, and is a parametric design method for natural ventilation of a cold gymnasium building. Background technique [0002] Due to its huge volume and strict requirements on the indoor physical environment, the stadium building is a major energy consumer in urban public buildings. Many scholars have shown through theoretical and practical research that the use of natural ventilation can improve the indoor thermal comfort environment while saving a lot of energy and funds, ensuring indoor air circulation, and improving air quality. The introduction of natural wind into the stadium building is beneficial to reduce its operating costs and promote the green, low-carbon and sustainable development of sports buildings. However, as a typical tall space, the gymnasium is more difficult to introduce natural wind. It is necessary to rationally optimize the building form and ventilation ...
