Energy Exchange : Federal Sustainability for the Next Decade Viridity Energy Inc. is Philadelphia based leading energy service provider ( Campus level –Operate multiple buildings –Minimize overall cost for the campus Viridity Energy Inc. level –Schedule multiple campuses –Virtually connect two campuses –Maximize incentives 4 operation schedule operation schedule incentives SMARTER: A Perspective from Industry Patent: PCT/US2013/039761

Energy Exchange : Federal Sustainability for the Next Decade Sponsored by NSF Cyber-Physical System Program (Sep – Sep. 2016) Objective: develop a decision framework to enable real-time autonomous, robust, and optimal building energy system operation decisions for temporally and spatially distributed building clusters. The framework includes innovative algorithms and tools for – Building energy modeling – Intelligent data fusion – Decentralized decisions and adaptive decisions SMARTER will transform the current centralized and uni-directional power distribution business model to a decentralized and multi- directional power sharing and distribution business model, reducing overall energy consumption and allowing for optimal decisions in changing operation environments. 5 Scope

Energy Exchange : Federal Sustainability for the Next Decade Multiple Pareto frontiers under different conditions (ASU/UB) Self-tuned noise tolerant models (DU /ASU) Adaptive Pareto decisions (UB/ASU) Validation & Dissemination Physical System: real building monitoring cyber data from university campus buildings Test Bed (DU/Siemens): a building cluster emulator validated by real building data Dissemination (ASU/DU/UB/Siemens): Tri-University Program, Workshop, Internship Program SMARTER: How next generation NetZero building clusters make operation decisions dynamically, autonomously, robustly with the assist of cyber data? Operation performance (e.g., energy consumption) for different condition (e.g., peak hours, off-peak hours) Control based transitioning from Pareto solutions What models? How do decisions evolve? What decisions? What impact?

Energy Exchange : Federal Sustainability for the Next Decade 7 Vision: buildings freely form clusters to share and exchange site-generated energy Needs: test bed for building clusters; high fidelity models; operation strategies Achievement 1: Building cluster hardware in a loop emulator Red line is the measured cooling energy consumption and Purple line is the forecasted consumption from our high fidelity model, which outperforms other popular models reported in the literature Achievement 2: High fidelity energy forecasting models are developed for building clusters and the performances are compared with other models in the literature. Our models presents better accuracy, extendibility, robustness, and computation efficiency
