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
Defending against even a simple airborne attack may require a complex
ventilation safety plan - or at the least, a well thought-out
strategy. Sensor capabilities, sensor placement, response speed, and
the general ventilation system are some of the factors that play into
protecting occupants (and even property) in the case of something
worse than an accident.
financing challenges did the first ancient Egyptian engineer face?
After setting the table with that interesting scenario, we move on to
modern engineering economics. There, calculating the cost of
generating one dollar of savings is joined by the value of assessing
the oft-overlooked cost of doing nothing. The result is a stronger
argument for sustainable building and retrofitting in the
contemporary age, and that’s no pyramid scheme.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
