While mechanical energy codes may lag relative to the efficiency targets of some other codes , the expansion of VRF into a wider range of equipment makes it easier than ever to exceed expectations. Perhaps more importantly, its incorporation into heat pumps, dehu-midifiers, compressors, and more represents more flexibility in delivering an effective retrofit without a total system overhaul.
Leaders at the Virginia Department of Motor Vehicles are expecting recent upgrades to the state DMV building in Richmond, VA, to reduce energy consumption by 36% and save $284,000 a year.
Does an old-school concept deserve consideration for a wider range of projects these days? After a refresher on the basics, warm up to a variety of current tips and advantages for
maintenance, controls, and installation.
When aging, outdated systems at Hardin Medical Center (HMC) provided inadequate cooling and insufficient humidity control, hospital administrators undertook a number of upgrades.
When the school board and town government of Bourne, MA, saw the unusually high utility bills for Bournedale Elementary School, they knew something had to be done.
Sometimes it’s less important to think outside the box than to notice that the stuff inside the box has changed. In the case of airside economizers, more modern components and seasonal opportunities can make things work swimmingly.
Modular boilers have come a long way in the past few years, along with load-matching strategies. Improving efficiencies, navigating critical tight spaces, and allowing for future growth are three reasons this option is heating up.
One of the worst things you can do is note the capacity and replace the chiller. Have the building loads and usage changed? What about motors and cooling towers? Consider these and your part-load realities to create real long-term improvements.
The replacement of chillers for hospitals and other health care facilities are often done out of absolute necessity, and it is often avoided for as long as possible.
