The article offers information about the two new construction commissioning projects with similar challenges and as-yet unwritten endings. The first project is one in which the commissioning professional was engaged before the schematic design phase, and the project is currently early in construction. The design engineers did not develop a detailed set of control sequences during the design phase.

The article offers information on topics related to building commissioning. Topics mentioned include the project managers for building commissioning, the financial management of construction projects, and the importance of capital project budgets management. Also mentioned are the role of heating, ventilation, and air conditioning (HVAC) in building commissioning and the importance of commissioning project.

The article provides a description of the terms "deferred testing" and "seasonal testing" that are common throughout the building systems commissioning world. The consideration of deferred testing to be universally defined as testing that cannot be effectively or conclusively performed during the construction phase is tackled. The seasonal testing is defined by the author as functional performance testing at near-design heating and cooling weather conditions.

The article discusses aspects of the commissioning standard for the building design system of the regulated and non-regulated industries in the U.S. It states that the end-user requirements and commissioning plans are developed for a variety of projects that utilize automated systems including fire protection and safety systems, electrical power system and heating ventilation and air conditioning. It cites the importance to achieve high-priority system performance of HVAC system.

The author describes the issue disclosed through analysis of the trend graph included in her May 2012 "Commissioning column, followed by a wrap-up summary on trend logs and new construction commissioning. She explains that the trend log analysis is not a substitute for field functional performance testing during new construction commissioning. However, she recommends analyzing trend logs and addressing performance issues identified through trend logging as a pre-test commissioning activity.

The article discusses on how to conduct a trend log analysis during heating & ventilation (HVAC) commissioning. It states that functional performance testing (FPT) is the culmination of the commissioning process but does not allow observation under normal operating conditions and load fluctuations. To supplement FPT, trend logs are used in validating the operation of HVAC systems. Using dataloggers to monitor and record control input and output points can also pinpoint operational issues.

The article discusses the commissioning of an office building for expansion. It notes that the commissioning team conducted functional performance tests at the end of construction and confirmed that all the heating, ventilation and air conditioning (HVAC) systems performed as intended. Moreover, the design and construction commissioning process was intended to match system integration, setpoints, and control sequences to the dynamic needs of building occupants and processes.

The article defines decommissioning as the removal of something from service while minimizing or eliminating danger to people and the environment. This may be applied to all building infrastructure systems, such as heating and ventilation (HVAC), electrical power, lighting circuits and fire protection. Commissioning is a pre-design through construction process intended primarily to mitigate problems typical to the end of construction projects of any type.
