NPS Defense Energy SeminarFederal, state and local governments are setting ambitious targets to reduce energy use of existing buildings through retrofits. It has been challenging for owners of large building portfolios (i.e. Cities, campuses and DoD installations) to identify and prioritize buildings and retrofit measures with the highest potential, due to the time, cost and expertise required for detailed energy audits. This presentation introduces new Rapid Energy Modeling (REM) capabilities for energy analysis of entire building portfolios with minimal data input. The energy modeling approach allows prioritization of buildings, evaluation of retrofit measures, and agile exploration of scenarios to achieve energy goals at a city-scale. Results are presented dynamically in the context of a digital 3D City Model and customizable dashboards. Additionally, the individual building information models (BIM) can be used for more detailed analysis of prioritized buildings. This approach can contribute to portfolio benchmarking/audit initiatives and can help guide data-driven planning and decisions for large building portfolios. This presentation will highlight a case study based on a project recently completed at the Tinker Air Force Base (Okla.) and workflow for high performance building design
