Brick is an open-source, BSD-licensed development effort to create a uniform schema for representing metadata in buildings. Brick has three components: (1) An RDF class hierarchy describing the various building subsystems and the entities and equipment therein (2) A minimal, principled set of relationships for ....Tell me more
BTrDB is a time series database for telemetry data, with emphasis on high performance insert, as well as logarithmic time aggregate queries. BTrDB was originally designed as the primary datastore for synchrophasor data in the ARPA-E Microsynchrophasors for Distribution Systems project, as no existing time series database ....Tell me more
Mr. Plotter is a data visualisation tool that leverages BTrDB’s sublinear aggregation queries to enable rapid interactive plotting of hundreds of millions of data points, while preserving the useful information in the data. It has been used extensively in the ARPA-E Microsynchrophasors for Distribution Systems project ....Tell me more
The Storm platform was designed to meet all the requirements of a general purpose modern wireless platform.Tell me more
With the Storm and Firestorm projects we explored how best to construct a low power 32 bit mote that could simultaneously handle complex tasks, but operate at extremely low power. With the Hamilton project we decided to explore the third dimension in the design space - cost. Can you make a low power 32-bit mote at a price point that ....Tell me more
Software Defined Buildings (SDB) seeks to design, engineer, and evaluate the foundational information substrate for cyberphysical systems in a concrete, canonical form - creation of efficient, agile, model-driven, human-centered building systems. Modern commercial buildings provide increasingly integrated Building Management Systems, but are typically closed or based on proprietary interfaces, are difficult to extend, and it is expensive to add new capabilities. Key underlying technology trends driving building system design are the rapidly declining costs of new cyber technologies, e.g., ubiquitous wireless communications, mobile devices, cheap embedded processing, and scalable processing and storage in the Cloud. The research challenge is how to extend the building “machine,” to harness these trends, making it better, more capable, and more efficient. Our approach is to develop software-defined buildings, to shatter existing stovepipe architectures, dramatically reduce the effort to add new functions and applications without “forklift upgrades,” and expand communications and control capabilities beyond a single stand-alone building to enable groups of buildings to behave cooperatively and in cooperation with the energy grid.
