Room for equipment is frequently tight, but in the case of this steam pipe, the room for error was less than one inch. The kind of planning that navigated that challenge accounted for (almost) everything in this tricky retrofit.
Tankless water heaters saved California State University Northridge money in energy costs. Beverly Watson can easily laugh about the idea today, now that her recent tankless water heater retrofit project
As noted in last month’s column, accessibility
to mechanical, electrical, and control system components is critical for
sustainable systems operation. However, the design and construction industry is
sorely lacking when it comes to agreeing on what appropriate accessibility
means. In order to make a meaningful difference in how systems are delivered to
owners/operators, it is critical to define measurable accessibility acceptance
criteria early in the design phase and allow the commissioning professional to
shepherd that criteria through the design, construction, and acceptance phases.
An energy analysis paid for itself at this Illinois bank by identifying energy savings opportunities. When Jason Vogelbaugh, director of Energy Solutions at Alpha Controls & Services, (Schneider Electric’s Rockford,
system experts see flow as a key step to optimizing system efficiency. Cutting
down required tubing size, insulated PEX for district systems, and
variable-speed pumps to pin down a chiller’s exact needs are three points of
attack in the modern campaign against waste.
