Space Requirements for Technical System in Office Buildings - Air handling plant room model

Abstract

This study illustrates how the air handling plant room geometry depends on the Specific Fan Power (kW/(m3/s)) and airflow rate (m3/s) by using a theoretical model. The total shaft area of an office building relate to the gross external area and ultimately examines the possibility to utilize the model together with the shaft area study to investigate various sizes of office buildings share of technical area. The analysis shows that there is a clear connection between total airflow rate and the air handling plant room area and the model is verified with good results compared with measured data for a number of office buildings. The conclusion is that the model seems to be consistent with reality. The results verifies the well-known and often used in practice graphs published by Enno Abel in 1999, when SFP was not considered to the same extent as today, can be used for air handling plant rooms designed for an SFP ≤ 1.5 kW/(m3/s).
