Has anyone had a problem with condensation in the "chasing" and how they solved it? Our building is 44 yrs old and the copper piping is going. Not sure if best to go with copper again or PVC with proper insulation. We think there is quite a bit of warm air from outside building getting into the space where the pipes are and in the Summer when the A/C is running, the chases (sp?)start to show water damage. We are experimenting with expensive insulation, but still no luck. Any suggestions? We are an 11 story building with 150 units.

The correct insulation with a vapor barrier to prevent condensation is a must. You should call IDC Corporation @ 1-800-327-8432 for more information for sweating cold water piping within a sheetrock chase.
If you are heating your building with steam it might be worth considering converting to hot water heat via a hydronic system and replacing all the risers. The cost to replace could make sense depending on the price/headache and stress associated with extensive repairs.
