Dynamic heat transfer simulation method of building envelope based on Laguerre polynomials model order reduction
This paper introduces the application of the model order reduction (MOR) method using Laguerre polynomials in building envelope simulation. The dynamic heat transfer problems of a single-layer roof with the sinusoidal outdoor temperature as well as a multi-layer wall and a two-dimensional corner of wall under the realistic outside solar-air temperature were solved by the direct numerical solution method and Laguerre polynomial model order reduction (LP-MOR) method. The relative error, solution time, and heat flux of the LP-MOR and other MOR methods were compared. The maximum norm of relative errors between LP-MOR and the directly direct numerical solution (DNS) method based on finite volume method (FVM) can be controlled within . Moreover, compared with solving small-scale discrete systems, LP-MOR is more efficient in solving complex models with a large number of discrete nodes.
