Simulation on indoor aerodynamics induced by an atrium fire

In China the development pace of green building is becoming more and more fast. But there are many technical problems during the green building construction. The Library of Shandong Jiaotong University is the first case of green library building in China. The ecological implementation in the atrium is one of the important ecological strategies of the Library. While construction we encountered more technical problems, especially the contradiction between the natural ventilation, natural lighting and fire safety. In this article based on the atrium technology design of the green building and combined the practice of the atrium some strategies realizing natural lighting, natural ventilation in the fire safety, applicable, economy and art.are summarized in detail. It is the aim to give some references and to promote the green building implementation.

Atrium Fire

Many atria are built in the Far East. Fire Safety is a concern and providing smoke management systems in atria is essential. For tall atria having difficulties to allocate space for air ductwork and fans of a dynamic smoke exhaust system, a smoke exhaust system with a ceiling vent is provided. The performance of the system should be evaluated and a two-layer zone model has been designed for such propose. The smoke layer temperature and interface height for a static smoke exhaust system in a tall space will be predicted. Based on the empirical formula derived from the entrainment rate of an axisymmetric plume and flow rate at a vent, a simplified calculation procedure of a static smoke exhaust in an atrium fire is proposed. Experiments were carried out at a full-scale burning facility of 27 m high, the USTC/PolyU Atrium, for verifying the results. It is found that the predicted smoke layer temperature and interface height agreed well with the experimental results. Therefore, the procedure is recommended to the authority as a tool in evaluating the performance of static smoke exhaust systems.

This article is a report studying the potential fire risk in atrium buildings in Hong Kong. The general shapes of the atrium buildings are sur veyed and classified into three types. Fire environments in those three types of atria are simulated using three mathematical fire zone models, the FIRST, the ASET and the FAST, developed at the Building and Fire Research Laboratory, NIST, U.S.A. In addition, simulations on four actual atria are also performed. All the results show that smoke will bring many problems, and controlling smoke is essential to providing safety in the atrium spaces.
