By orchestrating a number of smaller energy-efficient retrofits, the University of Utah generated enough
savings to finance a central chilled water plant for its health sciences campus. By Joanna R. Turpin
There have been numerous reports lately showing that schools are in dire need of structural and mechanical repairs, yet there are often no funds to fix the problems. For many schools, performance contracts may be the solution.
No, it's not with a whip and a chair, even though that may be tempting at times. Today's chillers are precision machines that rely on microprocessor-based electronic controls to not only provide more flexibility and reliability, but also to interact with just about any building automation system that's available.
Although oversizing of conventional systems is still a culprit at large, and certain desiccant advantages seem clear, some engineers would most like to get their hands on independent research proving exactly when desiccants are the superior dehumidification option.
There is a lot of buzz these days about desiccant dehumidification systems: Where should they be applied? How should they be specified and designed? In the first of two parts, the author finds that after talking with the experts, the answers to such questions can still be a little murky.
Gone are yesterday's unreliable and inaccurate sensors and controls. Today's devices, including temperature, humidity, and CO2 sensors, are not only highly accurate and dependable, they also last longer and provide buildings with greater comfort and energy savings.
The renovation of the Pentagon is well underway, including two revolutionary aspects for the federal government: The remaining Pentagon project will be design-build, and the whole structure will undergo extensive commissioning.
Boiler Maintenance & Lifecycle Costs; Proper upkeep can seem like a high bar, but it's nothing compared to a drain on the budget, an avoidable full replacement, or an on-site incident, read more in January issue.
