B-13 Introduction of actions to reduce environmental load in a large-scale building : Part6. A study on optimum air-conditioning operation for the grand lobby : Verification of indoor thermal/air environment and the energy-saving effect using natural ventilation

Abstract

In this part, the natural ventilation operation method for the grand lobby in interim season was proposed, and the field test was enforced from May 12-30, 2003, for the verification of indoor thermaVair environment and the energy-saving effect using natural ventilation. The results are shown as followings: 1) the lobby indoor thermal and IAQ conditions were maintained within the limits of the standard of the Act for Maintenance of Sanitation in Buildings; 2) the energy consumption for air-conditioning became zero compared with the same period in 2001 and 2002, and acquired the positive energy-saving effect. As a conclusion, the natural ventilation operation method for the grand lobby was very effective in practice.
