The retrofit project provides continuous building-by-building monitoring energy and utility cost analysis inventorying the chilled water flow meters and Btuh energy metering to determine decarbonization results.

Evaluating the latching requirements of both alarms and alarm responses can pay dividends when it comes to future building operations.

Far too often, building operators are overwhelmed with the number of alarms generated on their building automation systems (BAS). 

Project Delivery Method: Design-build (D-B)

Lead/lag pumping operations are common control sequences that are littered with nuances that oftentimes prevent them from being properly implemented.

Examining lead/lag control sequences for variable-speed distribution pumps.

If a system was designed to operate in lead/lag, but lead/standby was implemented, it would not be able meet the flow requirements during the highest load periods.

After 25 years, this will be my final contribution to Engineered Systems’ Commissioning column.

OPRs are intended to document, in clear, concise, and verifiable terms, the definition of success for the project.

The more automated and complex a building is, the more important it is to clarify control system technical requirements.
