Prediction of Temperature Gradients in Large Buildings (Paperback)

This document provides design guidance information on the efficiency of different methods of reducing stratification, considering different building heights, constructions and destratification systems. It also provides data on the likely percentage energy savings from the different systems given the initial stratification. The work comprises computer simulations using computational fluid dynamics to predict the performance of various methods of reducing stratification. Two stages were undertaken. Firstly, modelling of existing buildings, for which measured data was available, to demonstrate the ability of the computational technique to predict the environment. Secondly, modelling of different de-stratification systems in otherwise the same building and outdoor conditions to provide a direct comparison. It is the design information from this work that this publication addresses.
