The BACnet Advanced Application Controllers (B-AAC) BTL Listed ECB-300 is a microprocessor-based programmable controller designed to control various building automation applications such as small to medium AHUs, chillers, boilers, and cooling towers.
A lot has happened since the author’s 2008
article. It’s prime time to revisit expectations for BAS and chiller
optimization controls, and then have a look at several of today’s options for
anyone managing chilled water flow to wring the last drop of efficiency out of
Regulatory, competitive, and environmental
pressures are pushing data centers away from the traditional power sources.
Here, the author surveys the landscape and reviews one comparative study
involving CCP cogeneration and conventional electricity sources. Reducing the
carbon footprint and lessening reliance on a sometimes unreliable grid are just
two reasons to look into CCP.
Forget high-tech or
high-expense fixes for a minute. Have you tried to bump efficiency by looking
for the next aisle over, deploying a
Trim and Respond strategy, or trying the soon-to-be-famous Paper On A Stick approach?
Some of the biggest names in the data center universe think that you plant the
seeds of real savings with some mighty simple steps.
Here, our long-time forward-thinking columnist uses a common hospital scenario to walk you through the shift from Design-Bid-Build to an Integrated Project Delivery approach. See how the job can get done with similar personnel on a considerably shorter schedule, resulting in a greater team investment in the project’s success and yet more time to get on to other work.
Some thermal storage media are familiar to most
of us, but what about gravel? Or lake water? See how those can work in the
right environments, and tuck this away as a general refresher on thermal
storage concepts and options for use in hospitals, data centers, and elsewhere.
a concept, eh? The author takes a comparative discussion of chiller
technologies and options, and he places it squarely within the current events
context of domestic energy sources, the utility rate landscape, and thermal
efficiency. Read this and then look for Part 2 in the near future.
For a consumer food group’s very mixed-space campus, HGA’s careful outdoor air strategy got support from smart boiler, chiller, and lighting design to create performance tailored for the client while comfortably exceeding LEED®and ASHRAE 90.1 requirements.
Smaller in size but big on style and service, this Boston hotel looked to compete with bigger brands by cutting costs behind the scenes. A chiller overhaul led the list of improvements, which included lighting and controls retrofits, and allowing rooms to recirculate air when unoccupied.
