On the Design to Improve the Bathroom Exhaust Performance in Multi-Unit Residential Buildings

Abstract

The purpose of this experimental study was to improve the performance of bathroom exhaust systems. In this study, the performance of fans used in bathrooms was measured by a field test and laboratory test. Because there are no specific codes for bathroom ventilation in Korea, different construction companies implement their own regulations when installing fans in the bathrooms of multi-unit buildings. To determine if their exhaust performance meets the 8 ACH standard, field measurements were conducted and the construction methods and design methods were proposed to improve their exhaust performance. In addition, to provide the standard method for installing fans, laboratory tests were conducted to offer a design standard of the fan′s components.
