[TheForge] OT: Government waste

Ground source HVAC generally means a heat pump that exchanges heat with 
water that is circulated under the ground so it is 50-60deg year round. 
Much more efficent than exchanging heat with the air. Ground source is 
expensive to install because of the lines that have to be burried.

IF the system was due for a retrofit spending some money on the project
over and above just going cheap could make sense.  It depends on the
difference in costs and the value received.

I would even be willing to shell out a little bit purely for
demonstration value.

Civic buildings should be very well done. It saves in the long run.

e.g.Our water treatment plant is uber high tech inside, but the building
itself was built in the 30's and is still rock solid. I should last well
into its second hundred years.

Water based HVAC probably means heat pumps drawing heat from underground
aquifers or thermal springs.
