Automated Ongoing Commissioning via Building Control Systems

Abstract

ABSTRACTIt is well known that commissioning of new buildings is a great way to save energy and money. Likewise, re-/retro-commissioning existing buildings is an extremely cost effective way to recapture those energy savings that have been lost over time due to changes and failures in the Building Control Systems (BCS). There should be a better way to continually maintain energy savings over time. A superior solution is to use the existing BCS.Most buildings of any size or complexity are designed with a BCS to handle the complexities of an HVAC system. Most of the complexities are present to reduce operating costs—otherwise, all the BCS needs to do is to maintain a comfortable working environment by controlling space temperatures, humidity and air quality. To reduce operating costs, the BCS performs all kinds of additional, somewhat complex operations, as listed below. Air handling unit (AHU) scheduling—Schedule the air handler off after business hours with higher or low space temperatures and return to op...
