Big Green: ASHRAE 90.1 and maintainablity

[NEGS]

We've had no trouble reducing more than 50% of the GHG output of buildings. Infact, much more than 50% is easy to achieve. Thicker walls are the biggest portion of it, and using non-fossil heating plants is the remainder.

Maybee you should try another firm?

  "should" be able to, maybe.  Perhaps you can tell the various engineers on jobs I get to estimate how. 
  Right now for example i am working on a school that has a proposed mix of rooftop units and  air to air heatpumps for the classrooms - the latter a very short sighted solution IMO.  But they can hardly afford the building as it is.  Nobody wants to address almost certain rises in energy costs in the future.  The engineer points at favorable tariffs given by the electric co right now & I have to shut up.
  Problems as I see it (in general) - 
   - lack of up-front capital especially in public funded jobs like this, 
   - lack of financial expertise on the Green side of the table
   - lack of technical expertise and leadership from architects
