Abstract
After a short review of the theory associated with the numerical approximation of the diffusion equation for heat flow through solid elements of buildings, the paper concentrates on the effects of various discretisation schemes and nodal densities in terms of the effects on transient heat storage and surface temperature fluctuation. Since this is the most widely used method, the paper focusses on finite-difference modelling. However, the main conclusions are applicable to other numerical approaches as well. By practical applications, representing typical (passive) solar cases, it is demonstrated that it is easy to introduce - but also relatively easy to minimalize - errors due to nodal discretisation of building structures.
