Modelling of Heat Emitters Embedded Within Third Order Lumped Parameter Building Envelope Model

Joshua Fong, Chris Underwood, Jerry Edge, y Tindale, Steve Potter

Abstract: A dynamic modelling approach for heat emitters embedded within an existing third order lumped parameter building envelope model is reported in this work. The dynamic model has been found to provide more accurate results with negligible expense of computational time compared to a conventional quasi-dynamic model. The dynamic model also is preferred over the quasi-dynamic model as it allows for modelling emitters with high thermal capacity such as under-floor heating. Recommendation for this approach is justified through a series of analyses and comparative tests for various circuit options, timesteps and control volumes.
