During FY10-11, Pacific Northwest National Laboratory in collaboration with the EnergyPlus development team implemented the following high priority enhancements to support the simulation of high performance buildings: • Improve Autosizing of Heating, Ventilation, and Air Conditioning (HVAC) Components • Life-Cycle Costing to Evaluate Energy Efficiency Upgrades • Develop New Model to Capture Transformer Losses • Enhance the Model for Electric Battery Storage • Develop New Model for Chiller-Tower Optimization. This report summarizes the technical background, new feature development and implementation details, and testing and validation process for these enhancements. The autosizing, life-cycle costing and transformer model enhancements/developments were included in EnergyPlus release Version 6.0, and the electric battery model development will be included in Version 7.0. The model development of chiller-tower optimization will be included in a later version (after Version 7.0).
