5.1. Studies on the effects of windows and door opening on ventilation and thermal comfort
Some experiments were performed in a naturally ventilated room [89]. The room had two windows on each side of its three external walls to provide (1) side flow ventilation, (2) cross-flow ventilation, (3) adjacent-flow ventilation and (4) three-sided flow ventilation to determine tracer gas and particle exchange rates for some of the following windows-opening arrangements:
All windows were closed, one window half -open, two win- dows half-open, one window fully-open, and two windows fully- open. Some of her findings were as follows:
