John,

Linclon County Schools Study data (in 98 Dollars, ok for comparative
analysis, these included mostly water to air units, water to water will
be lower so data slightly favorable to chiller-boiler.:

GHP Maint Cost = 2.13$/yr/sq ft
Water Cooled Chiller w Gas Fired Hot Water Boiler $6.07/yr/Sq Ft

Subject: [Bldg-sim] O&M costs (UNCLASSIFIED)

Classification: UNCLASSIFIED
Caveats: NONE

I was asked to complete a life cycle cost analysis comparing a
boiler/chiller
system vs a geothermal system with a water to water heat pump.  I have
all
the factors I need except the illusive O&M costs. (I have fuel cost,
installation cost, equipment cost....)

What I have done at this point is to contact the company which will
actually
be doing the O&M.  (I went straight to the horse's mouth) but the campus
only
has 1 building with a geo-thermal system and it is only 1 year old.  I
think
if I can get a ratio comparing the O&M costs of a boiler/chiller vs
geothermal, I'd be done.

Something as simple as "A geothermal system on average costs x% less in
O&M
costs compared to a boiler/chiller system...." and somebody to site as
to the
value of 'x'.
