Taiwan’s building laws are very rigorous for envelope load of various buildings, and building envelope load should be calculated according to the Technical Code for Energy Conservation Design of Buildings. The complex calculation may undermine cooperative initiative of the industry. If computer aid can be used, the time for calculation and laws search can be save. To provide practical computer-aided calculation tool of envelope load for builders and academic departments, this study designed a computer-aided software BEEP-2010 which can quickly calculate whether the designed building meets the regulations. Java is used to write programs for this software. The database system applies the Relational Database. ER-model is used to normalize the database design. The user interface design adopts graphics mode to simplify operation interface. As long as the user understands basic concept of the envelope load, he/she only needs statistics of the area data and print the calculation result in the form of standard window to reduce the inconvenience in table search. Thus, this can greatly improve calculation efficiency of envelope load of Taiwan building businesses and help promote green buildings.
