Enhanced Sequential Search Methodology for Identifying Cost-Optimal Building Pathways

PDF Version Also Available for Download.

Description

The BEopt software is a building energy optimization tool that generates a cost-optimal path of building designs from a reference building up to zero-net energy. It employs a sequential search methodology to account for complex energy interactions between building efficiency measures. Enhancement strategies to this search methodology are developed to increase accuracy (ability to identify the true cost-optimal curve) and speed (number of required energy simulations). A test suite of optimizations is used to gauge the effectiveness of each strategy. Combinations of strategies are assembled into packages, ranging from conservative to aggressive, with so up to 71% fewer required simulations ... continued below
