The United States (U.S.) Department of Energy (DOE) Building Technologies Office (BTO) is seeking information from the public on sensor and control technologies that can be used within residential and commercial buildings to monitor and optimize energy performance and occupant comfort, as well as support energy-related transactions outside the building envelope. In particular, BTO is interested in the current state-of-the-art in sensor and control technologies, forthcoming research and development (R&D) advances that could reduce cost or improve performance, and the potential market implications of improved building energy management. There are five categories in which BTO is seeking additional information: 1. Multi-purpose Plug-and-Play Sensor Packages 2. Virtual Sensors and Predictive Models 3. Sub-metering, Continuous Commissioning, and Automated Fault Detection & Diagnostics 4. Occupant-Centered Sensing and Controls 5. Other (does not fit in one of the above categories) Eleven questions are presented, representing various aspects of information that are important for DOE to collect, such as: state of the art, metrics, qualitative criteria, R&D status, cost, market types, possible opportunities, improvements, and market barriers. This is solely a Request for Information and not a Funding Opportunity Announcement (FOA). Responses to this RFI must be submitted electronically to SensorsandControlsRFI@ee.doe.gov no later than 5:00pm (ET) on October 31, 2015. The full content of the announcement can be found on the EERE Exchange website at https://eere-exchange.energy.gov.
