Plenum Requirements For Egress Corridors In Health Care Environments

Incorporating a plenum can have its design advantages, but corridors serving adjoining areas of health care occupancies are prohibited from being used for a portion of an air supply, air return, or exhaust air plenum. This article and its illustrations can strengthen your grasp of the related NFPA code details and exceptions so you can design and ventilate properly for this special population.

A Boiler Plant Upgrade's Tough College Course

Here’s a task: bridge the new mechanical room to the utility connection in the old space - located in an adjacent building in Chicago’s South Loop.

Tomorrow's Environment: Software

Some will say most engineering, construction, and O&M software offerings are “smart” because they are all programs built for computer applications, but I see that some software has added benefits beyond their program intent. To begin, computer programs are developed to provide a variety of technical features, such as performing energy calculations and system/equipment service that blends technical data with financial data.
