LEED EAp2 Energy Modeling for a Mixed-Use Office Tower

DesignBuilder · EnergyPlus

A whole-building energy model developed for a 24,000+ m² mixed-use office tower to support LEED EAp2 performance evaluation. Baseline and Proposed models were built in DesignBuilder/EnergyPlus under ASHRAE 90.1-2016 Appendix G, with detailed representation of HVAC, central plant operation, site energy, utility cost, GHG emissions, and model performance validation.
