NIST researcher develops prototype automated commissioning tool with french scientific and technical building center (CSTB).A NIST (National Institute of Standards & Technology, Washington, DC, www.nist.gov) The standards-defining agency of the U.S. government, formerly the National Bureau of Standards. It is one of three agencies that fall under the Technology Administration (www.technology. researcher participated in a 3 month collaboration with CSTB CSTB Centre Scientifique et Technique du Batiment (France) CSTB Computer Science and Telecommunications Board (NRC) CSTB Computer Science and Technology Board CSTB Computer Science and Telecommunication Board in Paris, France, to develop an automated commissioning tool for building air handling units. After developing the concept for an automated commissioning tool, NIST partnered with CSTB to code the fault detection algorithm, develop the graphical user interface graphical user interface (GUI) Computer display format that allows the user to select commands, call up files, start programs, and do other routine tasks by using a mouse to point to pictorial symbols (icons) or lists of menu choices on the screen as opposed to having to , and test the prototype tool on a real system. The retro-commissioning project took place in the ARIA Building at CSTB where none of the three constant air volume air-handling units had been previously commissioned. By interfacing the automated commissioning tool to the building energy management system, test scripts The instructions in a test program. It defines the actions and pass/fail criteria. For example, if the action is "to enter a valid account number," the expected result is that the data are accepted. Entering an invalid number should yield a particular error message. See test case. can automatically command changes to system setpoints to achieve various operating states and document system responses. In preliminary results, several faults having significant impacts on energy consumption and occupant occupant n. 1) someone living in a residence or using premises, as a tenant or owner. 2) a person who takes possession of real property or a thing which has no known owner, intending to gain ownership. (See: occupancy) comfort were identified, including sensor errors and improper setpoints. CONTACT: Natascha Castro, (301) 975-6420; natascha.castro@nist.gov. |
