| Abstract |
Recently, Building heights have been higher and higher. Stack effect in building has been bigger in its size by this tendency and has caused various problems which are obstructions in aspects of dwelling satisfaction and building performance in high rise-building. Two main causes of stack problems are focused on pressure difference and air flow rate partially on composition elements of building, of which air flow rate is apt to become a important influence item on efficiency of heating, cooling and ventilating by increased its volumes. The understanding such as “Adopting the revolving door at an entrance can decrease stack effect problems” is generally accepted. But adopting the revolving door as a local solution is not adequate for decreasing total air flow rates in building. This study executes the simulations about variable characteristics of air flow rates according to the kinds of building stories, airtightness of envelope and adapting locations of the revolving door on air flow paths. And the results are described quantitatively and clearly. |
