[Equest-users] pneumatic to ddc savings?

[Umesh Atre]

We are working on a school project where the clients wish to change
their pneumatic controls to DDC. It is a 20 year-old building.
Can anybody comment on what the range of savings is? The existing system
is a 2-pipe for most spaces, currently being modified to a new 4-pipe.
Is it even possible to quantify the savings, if any, using eQUEST? 
Thanks,
Umesh
