Testing, Demonstrating and Extending the BASAT

PI: Michael Bobker, the City College of New York


Executive Abstract

Experience with building operators indicates that building automation systems (BAS) are widely under-utilized and lack important capabilities for what are considered high-performance operations that are current best-practices in the industry. High performance operations are connected with practices such as retro- and on-going commissioning that are known to have energy-saving potential in the range of 15 – 25% while improving comfort and productivity conditions. Control functions relate to the integration of various thermal systems, ventilation, motor control, and lighting. The over-arching goal of the research is to develop a tool that will enable credible, third-party, site-specific information that will support managerial decisionmaking about BAS improvements and upgrades. The currently proposed work continues and extends work that has been in progress for the past year under initial funding from the New York State Energy Research and Development Authority (NYSERDA).

Objective 1: To demonstrate use of a first-phase BAS Assessment Tool (BASAT) in pilot site chiller plants;
Objective 2: To document the findings, recommendations and client/site staff responses, comparing across at least three pilot sites;
Objective 3: To extend the BASAT to an additional HVAC system, such as air-handling units, or other building system (to be selected in consultation with sponsor);
Objective 4: To develop a data requirements framework for use of wireless sensors in extending BAS for specific systems, integrating with other SIBS research at CCNY.
