This Final Report summarizes the complete work performed by Annex XV Participants in two and one half years activity, presenting a set of data and information on energy consumption in School Buildings and Systems. The material presented represents the accumulated knowledge and experience of the experts taking part in this work. The aim of this Report is also to provide School Managers and Operators with advice on methods and procedure, to operate their systems efficiently and thereby reduce their energy consumption and cost.
So as to better understand and predict IAQ problems, the velocity field and distribution of local mean age of air were determined experimentally with three-dimensional anemometry and decaymode tracer gas measurements inside a classroom. We also performed 3-D numerical simulations of the velocity field in this room, using a CFD code. The time dependent concentration decay of tracer gas was simulated using the previously determined flow field in the pollutant transport equation. Relatively good agreement was found between the simulated and experimental concentration decay curves.
