- Abstract
- DTAM1 is a general purpose building energy simulation based upon discrete analysis techniques, including, but not limited to, the Finite Element Method, used in other fields of physical simulation. It is the product of a first phase of development of Discrete Thermal Element Analysis Techniques for Building Energy Simulation that are expected to provide a means to unify existing building energy simulation theory. DTAM1 provides a library of discrete thermal elements, that may be assembled to model thermal systems idealized to have constant material and heat transfer properties (i.e., linear idealizations), including: ID two-node thermal resistance elements; single-node lumped capacitance elements; two-node fluid flow loop element; ID two-to-four node isoparametric conduction Finite Elements; 2D four-node isoparametric conduction Finite Elements (planar and exisymmetric).
