Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

Abstract

The OpenBuildingControl project develops tools and processes for the performance evaluation, specification and verification of building control sequences. This paper describes the tools developed to verify that building control sequences are implemented as specified in a vendor-neutral, executable specification. The verification is done by testing whether trended time series, compared to the simulated control response, are within user-specified tolerances for time and for the trended variable. Morever, sequence diagrams are used for inspection of the control response. The paper gives an overview of the OpenBuildingControl process and describes tools for the control verification. It presents and example in which we successfully verified that an actual implemented control sequence conforms to its vendor-independent specification. It closes with discussion of experiences collected during this verification and with alternate approaches that can improve the operational performance of buildings.
