In many large commercial buildings, central-station air handlers are used to maintain occupant comfort. Often, these units include return fans, which draw air from occupied spaces for recirculation or exhaust.

First Changes to New Green Standard Proposed

Changes to the new standard for the design of high-performance green buildings have been proposed. ANSI/ASHRAE/USGBC/IES Standard 189.1, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings, is the first code-intended commercial green-building standard in the United States. The standard provides a long-needed green-building foundation for those who strive to design, build, and operate green buildings. It covers topics such as site sustainability, water-use efficiency, energy efficiency, indoor environmental quality, and a building’s impact on the atmosphere, materials, and resources. [MORE]
