GBlist: How to outgas a new building?



MARY:  Clearly, reducing the sources of pollutants (indoors and
outdoors) is the most effective, direct strategy.  In addition,
"building flush-out" (hi air exchange rate and hi air mixing/surface
velocity), even at normal temperatures, can avoid unnecssary pollutant
exposures during initial occupancy.  California's bldg. stds. now
require a daily pre-occupancy flush-out of non-residential bldgs.
(contact Calif. Energy Commission, 916.654.4064 re: Title 24 bldg.
design stds.).  Swedish researchers recommend running the HVAC at high
outdoor air flows for up to 6 months after initial occupancy (see
articles by Birgitta Berglund, Indoor Air proceedings, ASHRAE
proceedings, etc.).  Annual inspection and mintenance of HVAC systems in
workplaces is also required in Calif.

Building commissioning, i.e., performance testing of all systems in a
completed building, should help avoid many problems typically found in
new office building  ventilation systems.  Based on energy savings
alone, building commissioning appears to be very worthwhile.  See
previous Bldg. Commissioning conferences at
http://www.teleport.com/~peci/index.htm, and Sustainable Bldg.
conference at
http://fcn.state.fl.us/fdi/e-design/online/9704/cx-dade.htm. The State
of Florida has also begun using bldg. commissioning in its new bldgs., I
gather.  Canada has an R2000 Office Building project in progress that
may be of interest too.

The Calif. Dept. of Health Services IAQ Program has recently produced
VOC Guidelines which address these issues.  Contact Leon Alevantis,
510.540.2132, lalevantis@hw1.cahwnet.gov.

Subject: GBlist: How to outgas a new building?

Does anyone have references or information on how to outgas a new 10
story
office building by heating it up to outgas or any other methods?  I
remember reading something about heat to outgas, but I can't find the
reference.  My husband is moving into this building next year and we
were
talking about ways to minimize sick building problems since the builder
did
not do any greenbuilding techniques to our knowledge.  Hopefully,
greenbuilding practices will be the "norm" in the future instead of the
exception!
