B-14 Introduction of actions to reduce environmental load in a large-scale building : Part7. A study on optimum air-conditioning operation for the grand lobby : Measurement of natural ventilation rate and evaluation of outdoor air distribution

Abstract

This study focuses on the optimum air-conditioning operation for the grand lobby at the Harumi Island Triton Square. In this part, after the passive ventilation method, using leakages of the external perimeter wall and stack ventilation of attached high rise buildings, was proposed, the field measurement on ventilation rate with tracer-decay-method was performed, and results proved that ventilation rate: doors open 0.7〜1.0 ACH; doors close 1.5〜1.7 ACH, and air flow passes were secured in the intermediate season.
