Link below is for BOAF informal interpretation.  It may be of some
assistance.  Please note however that this is only an informal
interpretation...and may not reflect the opinion of all building
officials.  If there is something more definitive on this issue, I am
not aware of it.

Subject: Re: [Florida Code Talk] Partial change out of HVAC equipment
andThermal Efficiency Standards


Existing buildings are covered under the FBC-E under Chapters 5,6, and 7
for Level One, Two and Three Alterations under the section for ENERGY
CONSERVATION.  The minimum requirements for energy conservation is
referred to Chapter 13 ( Energy Efficiency ) of the Florida Building
Code in each case.  It is interesting to note that EXISTING BUILDINGS
ARE EXEMPT from Chapter 13 requirements unless the building meets the
requirements for classification as a RENOVATED BUILDING,  A CHANGE IN
OCCUPANCY, OR A PREVIOUSLY  UNCONDITIONED BUILDING to which comfort
conditioning is added. ...F.C. 13-101.5

IMHO it appears that section 13-101.6 for thermal efficiency standards
does NOT apply for the majority of partial replacement of components of
a mechanical system.  The Code as currently written appears to exempt
the exception requirements found under 13-101.6 and would be better
relocated as an exception under 13-101.5 EXEMPT BUILDINGS.

What say you all?

Actually the Florida Building Code does address systems that are not a
complete change out.  It is found in chapter 13-101.6.  Though only one
part of the system is replaced the whole system must be matched.  This
can be accomplished by one of four means,

 

1.  ARI (AHRI) data

2.  Accredited laboratory (example ARL labs)

3.  Mnufacturer's letter

4.  Letter from registered P.E. State of Florida.

 

I hope this helps.

 

Steve
