Research Background

SMARTER: Smarter Manager for Adaptive and Real-Time decisions in building clustERs

Energy Exchange: Federal Sustainability for the Next Decade3

• SMARTER System (Building Clusters) — Be resilient to disturbance— Reduce energy consumption— Save overall energy cost— Improve environment sustainability

• Next Generation Building Systems

– Interconnected (physically, virtually)

– Share energy resources – Freely exchange information

Proposed Concept: SMARTER

Energy Exchange: Federal Sustainability for the Next Decade

SMARTER: A Perspective from Industry

Patent: PCT/US2013/039761

Energy Exchange: Federal Sustainability for the Next Decade5

• Sponsored by NSF Cyber-Physical System Program (Sep. 2012 – 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.

Research Roadmap

Energy Exchange: Federal Sustainability for the Next Decade7

• 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
