Proposed simplified energy calculation procedure for use in energy conservation standards activities

In order to circumvent various difficulties involved in using the computer simulation-based building energy analysis procedure, a simplified manual procedure suitable for commercial buildings (internal and solar heat gain dominating over the envelope conduction heat transfer) was developed. This modified bin method compared favorably with seven computer simulation-based procedures, at least for a typical office building analysis, for Washington, DC climate. The basic principle of the proposed procedure, sample building data, and the results of parallel calculations with seven computer simulation-based energy analysis programs are described.
