GBlist: Are Green Dairy Barns Qualified as Greenbuildings?

["Carmine Vasile" <gfx-ch@email.msn.com>]

    If so, the excerpts below from an E-mail received a few days ago may be
of interest to "Green" Barn Designers  ----- since PA Dairy Inspectors
require a 40-cow dairy to dump140 gallons/day of water @ 150*F, minimum.

    Does anyone know how many cows there are worldwide and if this is a
common practice?

    In the dairy operation described below, over 32.8 kWh-thermal per day go
down the drain so it's cost-effective to recycle 70% ---- or about
8,400kWh/yr ---- & save $713/yr @ 8.5-cents/kWh, for an average cold water
temperature of 55*F.


    ...."here is some more info on the milkhouse situation, at least here in
northern Pa. Many 40 to 100 cow dairies which can be characterized as "small
operations". Milking is twice a day, year round, although as the number of
cows increases, some dairies go to milking 3x a day.

In my neighbor's low budget 40 cow dairy, the 4 milkers(contraptions that
suck milk out of the cows) hang on a rack that is suspended in a stainless
washtub. There is a controller made by SURGE (a company that makes dairy
equipment) that controlls the wash and rinse cycle and dispenses cleaning
chemicals. There is a solenoid controlled valve on the bottom outlet of the
wash tub that opens and closes the drain on the bottom outlet of the tub
which in his case dumps onto the floor and runs to a floor drain. Not all
dairies use the floor like this.

Each washing  in this dairyuses a total of 70 gallons of hot water. Dairies
with more cows , which have longer pipelines to wash, use more hot water.
The dairy inspector assesses the water temp by measuring the temp of the
wash water as it LEAVES the drain on the bottom of the wash tub. The water
MUST be at least 150 deg. F!!! and down the tube it goes" .....

    The situation described above uses an electric water heater, but others
in the neighborhood use natural gas, propane and fuel oil.
