2. ENGINEERING AND TECHNOLOGY
The most commonly applied mathematical solution techniques for building energy simulation are response function methods and finite difference methods. The accepted validation methodology in this domain has as its main elements empirical validation, analytical verification and inter-model comparison. Of these, only analytical verification tests the solution method exclusively; but the test examples used are too confined to be representative of the building energy problem. A discriminating and comprehensive test method for the validation of solvers in this application is proposed here. It employs solutions of arbitrary accuracy for test problems of realistic scale and complexity in what are termed numerical experiments. The necessity for – and the effectiveness of – the proposed validation method is demonstrated by its application to a set of numerical solvers.
