We discuss the application of an end-use load shape estimation technique to develop annual energy use intensities (EUIs) and hourly end-use load shapes (LSs) for commercial buildings in the Pacific Gas and Electric Company (PG&E) service territory. The results will update inputs for the commercial sector energy and peak demand forecasting models used by PG&E and the California Energy Commission...

This paper describes the development of a web-based, code-compliant ASHRAE Standard 90.1-1999 commercial simulation for Texas. Included in the paper is a description of the software and database platform used in the web application and how this software is attached to the DOE-2 legacy software running on a cluster of servers. This tool will be used by commercial builders in Texas to check code ...

In a power system, having a high level of renewable energy penetration requires a large amount of ancillary services to balance the supply and demand in real time. Commercial buildings have significant thermal capacity and so offer large potential for providing such services. Recent research has shown that the power consumption of the Heating, Ventilation, and Air Conditioning (HVAC) system can...

Energy information systems (real-time acquisition, analysis, and presentation of information from energy end-uses) in commercial buildings have demonstrated value as tools for improving energy efficiency and thermal comfort. These improvements include characterization through benchmarking, identification of retrofit opportunities, anomaly detection to inform retrocommissioning, and feedback to ...

Building heating and cooling accounts for nearly 18-24% of all energy usage. Building energy management can reduce both its operating costs and its carbon footprint. We propose the use of a factored Partially Observable Markov Decision Process (POMDP) to model and efficiently control a commercial building heating system. We use supervised learning and ground truth data to capture the parameters...

Open Automated Demand Response (OpenADR), an XML-based information exchange model, is used to facilitate continuous price-responsive operation and demand response participation for large commercial buildings in New York who are subject to the default day-ahead hourly pricing. We summarize the existing demand response programs in New York and discuss OpenADR communication, prioritization of dema...
