The DOE-2 building energy analysis computer program is being modified by the Los Alamos National Laboratory to include thermal storage wall modeling capabilities. This paper discusses model development and validation for vented and unvented thermal storage walls and water walls in DOE-2. The unvented wall model was validated by comparison with test-cell heating loads for both a selective surface and a night-insulated wall. The two commonly used vented wall models, the Akbari and Borgers correlations and the Bernoulli equation algorithm, were compared and tested against available wall performance data. The Bernoulli algorithm was chosen for use in DOE-2 because of its ability to simulate vent restrictions.
