Now comes the hard part for green and sustainable building.
Two
meetings that I attended recently have led me to one conclusion: The
plumbing-and-mechanical industry is past the feel-good, “green is good”
discussion on sustainable buildings. Now comes the hard
part.
What’s up next are building owners and other end users seeking reliable answers
on how to construct and maintain green facilities. Your role as an engineer in
providing your technical expertise is critical.
This next phase is going to get messy. You’ll have to sort through conflicting
information from different sources by becoming as knowledgeable as you can be
about green buildings.
A number of organizations have issued their own green standards and ratings,
some of which may conflict with one another. At last month’s spring meeting of
the Plumbing Manufacturers Institute, members talked about the need to
consolidate green standards from different associations in a way that reminded
me of their discussions on consolidating trade shows. I’m concerned that we’re
starting down the same path that will result in added expense and duplicated
efforts.
IAPMO, also in April, convened the first meeting of its
Green Technical Committee. The committee, says IAPMO staff member David Viola,
has “the opportunity to oversee the field to see what’s right and wrong, and do
something about it” by developing green plumbing, mechanical and solar codes.
Certainly, such an effort is needed.
More mixed signals are coming from Madison Avenue, which has discovered green
in a big way. Consumers are being inundated with advertising that makes green
claims for a whole host of products, only a portion of which purists would
consider truly green.
This “greenwash” worries me only because it’s making some people skeptical
about anything claiming to be green. While such advertising raises the public’s
green awareness, it should not be allowed to diminish the important gains that
sustainable buildings can make in energy efficiency and water
conservation.
And even accepted green concepts such as graywater and rainwater reuse need an
engineer’s expertise to turn them into practical realities. Presentations at
the PMI meeting demonstrated how important the capture, storage and transport
of recycled water are. Without proper design, these systems can create health
hazards that far outweigh any green benefits.
At IAPMO’s Green Technical Committee, members argued whether multi-head shower
systems have any place in a green plumbing code. While acknowledging that each
showerhead may be water efficient, some members questioned whether a system
with two or more showerheads is in line with green objectives.
Arguments among well-intentioned green proponents will continue to occur during
this next phase of our industry’s involvement in sustainable buildings. People
who are passionate on this subject should continue to air their views so that
all voices are heard.
PM Engineer will continue to serve as a forum for different points of view on
this subject, as well as an important source of information for you, through
our magazine, Web site, e-newsletter and Webinars.
Any conflicts or disagreements cannot be allowed to deter our industry from the
tremendous opportunity and responsibility we now have to make a difference.
