Abstract
This paper describes a systematic methodology for the development of
calibrated thermodynamic Computational Fluid Dynamics (CFD) models for
controlled environments in buildings utilising wireless sensor networks. The
calibrated CFD model will be used to optimise the positions of the physical
sensors for the management of energy efficient internal environments by building
operators.
This methodology could result in significant energy and economic savings and
lead to more accurately controlled internal environments. For the simulation of an internal environment, a CFD model of one of the
study rooms in the Nursing Library at the National University of Ireland in Galway, Ireland
has been developed. Data obtained from an on-site weather station and wireless
sensors provided boundary conditions for the CFD model. A well-positioned wireless sensor network collected real-time data at multiple
locations within the indoor environment. The data were compared with CFD model
results and a calibration procedure was developed. The presented research compares
the model outputs and the measured data, and outlines the calibration
procedures to date.
