Cradle to Cradle Energy Modeling: Achieving high-performance building means going beyond 'One and Done'


As the design community continues to push the envelope of high-performance building design, the need for energy modeling at different stages throughout a building's life-cycle has increased. Traditional energy modeling has historically supported one specific end goal, e.g. achieving a green rating standard or utility incentive. In this session, we will go beyond the traditional practice of 'one and done' energy modeling to illustrate the benefits of iterative modeling at each stage of a building's life-cycle, highlighting the difference of each model and the unique value it provides in supporting performance goals. Starting with conceptual analysis to inform early design decisions to design models for code compliance, utility incentives, and green rating standards followed by operational benchmarking to ensure the most efficient use, there are many types of models - each specifically created to support building decisions from cradle to cradle. Attendees will explore the variety of models used to realize different energy goals; understand the technical perspectives needed to determine how to best approach specific conceptual, design, and operational goals; and learn how changing standards (utility code, code compliance, green building ratings, sustainability challenges, technologies) and building operation raise the importance of accurate and timely energy modeling.
