October gets us to the cusp of winter in a lot of the country. The cold-weather threats to good performance are outnumbered only by the possible strategies to combat them. Here, the authors look at humidity, economizers, pipe and coil insulation and placement, and more as they assess the design opportunities and pitfalls once the temperature takes a dive.

Old drives, short circuits, and steam leaks represent a few of the little things that can bring down your green efforts. Elevate your level of service by attacking them, evaluating options like desiccants and economizers, and incorporating processes like sustainability audits and even recommissioning when needed.
