[Bldg-sim] Do Energy Codes apply to replacing HVAC equipment?

Virtually all Building Codes (which trump ASHRAE Standards) require ALL new
work and alterations to existing buildings to meet the current codes,
including energy codes.  Some jurisdictions allow replacement equipment to
have lower efficiencies than for new work.  So the answer to your question
is a definite "maybe".

 

Probably your best approach is to search online for the MN building codes to
see if it is one of those jurisdictions that differentiate between
replacement and new equipment.  Many jurisdictions post their codes, or at
least the revisions to the model codes online.

 

Best of luck.

Varkie, not sure if you got any replies to this one.  6.1.1.3 in 90.1-2007
says that direct replacement equipment should still meet the mandatory
efficiencies.

Does a condo bldg (400,000 sf, 28 flrs, built 1985, Minneapolis) have to
comply with the energy code when replacing the plant equipment?
