Here are a few interesting things to keep in mind when designing an equipment room. First, these spaces usually take up 7% of the gross floor space when located within the building or on the roof.

How is variable refrigerant flow (VRF) working for you? We asked a number of people that question and summarized the findings from two typical facilities here.

The Air-Conditioning, Heating, and Refrigeration Institute will hold its 2013 annual meeting Nov. 17-19 at the Ritz-Carlton on Amelia Island.

Since energy efficiency is a big part of what this industry pursues on behalf of society at large, I always like to see examples of what companies and firms are doing internally to conserve resources. This month, A.O. Smith celebrated progress on that front at its plant in McBee, SC.

The Houston Methodist Hospital in Houston, TX, comprises over 5 million sq ft and includes a central utility plant, steam production, and CHP capable of producing 14,800 tons of chilled water capacity.

I have a pet peeve with HVAC design engineers who do not put enough thought into a project’s contract document specification for training the client’s operation and maintenance personnel.

This project team left nothing to chance when it came to designing a five-story mixed-space facility for a Chicago gaming company. They also dealt a full hand of space-specific tactics: upgraded DX units, a dedicated variable-speed kitchen exhaust system, underfloor air, and better motors and drives improved the odds for efficiency. Pull the handle on this project story to get to the payoff.

The University of Minnesota’s Itasca Biological Station and Laboratories is one of the regions premier inland biological field stations.

This is the conclusion of my series addressing training for buildings where O&M will be outsourced.

Engineers are rethinking the standard engineering design paradigm, using lifecycle cost analysis (LCCA) to compare system alternatives that fulfill the same functional requirements but differ in terms of initial and operating costs.
