Pressurization Control in Large Commercial Buildings

摘要

The role of outside-air-static-pressure-measurement termination and control sequences in system optimization. Many large commercial buildings utilize direct-measurement building-pressurization-control systems. Optimizing the performance of those systems as part of a retrocommissioning project can yield energy savings and improved IAQ through reduced return/relief-fan speeds, reduced infiltration, and proper outside-air intake. ASHRAE President Gordon V.R. Holness, PE, FASHRAE, has urged ASHRAE members to focus on increasing energy efficiency in existing buildings. Optimizing the performance of building-pressurization systems can be a low-cost method of doing that.
