TABLE 101.4.1 APPLICABILITY
a An existing building or
portion thereof shall not be altered such that the building becomes less
energy efficient than its existing condition. b Minimum equipment efficiencies shall be met only
when equipment is installed to specifically serve the addition or is being
installed in conjunction with the construction of the addition. cIf an existing building is
unable to meet one or more current prescriptive code minimum requirements, it
may be exempt from those minimum requirements if the entire building is
brought into compliance by Section 405 or Section 506, as applicable. d Buildings undergoing
alteration that vary or change insulation, HVAC systems, water heating
systems, or exterior envelope provided that the estimated cost exceeds 30
percent of the assessed value of the structure (See Ch. 2, Definitions). |
Inconsistency with State law. Considerable confusion has ensued concerning the treatment of existing buildings. Because it is so difficult to determine the efficiencies actually installed in existing buildings and because it is so expensive to renovate existing buildings, the mandating legislation in Chapter 553.906, Florida Statutes, exempted buildings not meeting the definition of RENOVATION1,3 from compliance with the code and required only that the component(s) being changed be brought up to code where a major renovation is taking place. Also confusing the issue is recent legislation that requires equipment sizing and duct sealing. Unequal enforcement of these provisions, in conjunction with significant changes in how refrigerants are treated nationally has caused complete system replacement, additional expense and unlicensed activity. Staff recommends that the original Legislative treatment of Renovations be used across the board. |

TAC Comment
– May 24, 2012 - Glitch Jon motion that this does meet glitch
criteria (b) and (f). 2nd –
Wojcieszak Vote – unanimous approval.
COMMISSION
actions –June 12, 2012 – Glitch (Deferred) Note:
Send back to Energy TAC to come up with a technical recommendation to
reconcile differences in table. E. Lacey has provided comment
in Exhibit #1. 75% of windows sold in Florida are replacements. M. Nau,
PGT. Support Lacey’s position. R. Wright, Custom Window Systems.
Support Lacey modifications. FBC has established a standard for windows. Only
a slight cost difference between meeting standard and not: have to use a
separate piece of glass. Benefits tremendous, cost payback quick. R. Greeson. On behalf of SEEA,
urge support of Lacey proposal. Intent: provide cutting edge issue in state.
Report ACEEE, could save consumers $415 billion annually. Opportunity to
assist citizen in years to come. J. Gascon, Miami-Dade. Want to
make sure Commission understands implications on other areas of code,
including roofing. Mark Zehnal. Agree with J.
Gascon. Will significantly increase cost of roof. Dudley, Esq. Representing RECA
and Custom Windows. Agree that there are glitches in table. Position is that
all inconsistencies with state statute are the extent of glitches. If adopt
Lacey proposal, clarifies all inconsistencies. This is a legal question. J. Belcher. Writing in support
of staff proposal as supported by TAC. “Window that complies with the code”,
means default table values. Section 101.4.1 says to comply with code. If
don’t exceed 30%, don’t have to comply with rest of code. When you change
windows, impacting the envelope. Only referenced in 553.906. K. Hebrank.
Support TACs recommendation on this Table. S. 553.902 define “renovated
building”, as 30% of cost of structure. Definition has been in place since
1978. Table 101.4.1 is a “glitch fix” because there are conflicts in code.
“Code compliant windows” were those in effect before code implemented
3/15/12. E. Lacey. Point by Gascon,
roofing. Wouldn’t be changed if not specifically required by code; not aware
of such a requirement. Justification
used by Belcher and Hebrank specified by statute.
Staff’s recommendation takes two categories and applies 30% threshold to both
categories. A. Stewart. Have to disagree
with Hebrank that this is the result of unintended
consequences. Lots of meetings; 2009 Work Group meeting did consider impact
of replacing windows. L. Olson, Window Industries.
Support Hebrank’s comments. [C. Browdy:
question. Testimony re: increased cost of window.] Increased cost is between
20 – 30 percent based on manufacturing cost to end user. AVP Windows & Doors. Believe code and
Statutes has been in place since code’s inception, should be maintained as
reads. Looking at a differential between 30-40% to the homeowner. Difference
is between single pane windows and insulated glass: double glass, frame to allow
insulated glass. Safety design pressures are problem. Homeowners like
flexibility. R. Wright, Custom
Windows: On cost issue, important to
clarify difference between impact windows and non-impact windows. Non-impact
window is 2 sheets of glass separated by air space and spacer: relatively
inexpensive. If impact window, highest cost is lamination, not extra cost of
glass. Incremental window in impact resistance, 15%, non-impact about the
same. L. Ross, Intech
representing DOW chemical. Testimony brought up includes other products. This
is about energy conservation. Other code that affects alterations is FBC,
Existing Building. If staff recommendation is adopted as read, now creating a
new conflict with FBC, Existing Building. With staff recommendation will
never have increased standards for products. A. Hickman. Agree with Belcher
and Hebrank. D. Wilkes. Replacement window
are exempt in energy code. Belcher has referenced Stanton: Default table is not
code minimums; it is applicable for non-labeled windows. Commission discussion. Motion and second: It is a
glitch. Approved unanimously. Fix: Gregory: If lose a window in a
storm, structure is diminished. Re: definition of Renovated building. See
window as part of exterior envelope.
[Lacey: agree] If homeowner wants to replace 1 window, why require
replace with energy efficient window? [Lacey: if just replacing 1 window, not
a renovated building, but there is a standard in code for replacement of
fenestration]. Gregory sees additional requirement on citizens. Allow
choices, not requirement on populace.
[Blair: should be deciding how to fix the glitch][Browdy:
Need legal opinion from own staff. Hammond: Statute seems to not be clear. When not
clear, not up to the Commission, it is up to Judicial and Legislature. Best
Commission can do is act on what is available today. Not a simple issue
because statutes is not clear. Rules can help interpret statute, not
fix. Laid out as clear as possible
without further input. Anderson-Adams: Laid out as clear as possible. Shock: In favor of glitch
(staff proposal). Impact far-reaching. Cost to homeowner additional when just
fixing house. Intent of legislation was to not make measures worse, rather to
fix without bringing up to code. Tolbert: Existing building
code has threshold for when code is brought into effect. Hard to believe that
an energy code requirements are more
important than a life safety requirement. Smith: This is more reaching
in terms of impact, than air-conditioning. Looking at replacement of a/c
system or pool pump. Should treat envelope separate from a/c & systems. Franco: Agree with Lacey.
Constantly looking for improvement in energy efficiency. Doesn’t make sense
that replacement windows not meet code. Impact on other systems another
factor. Cost will come down, will become more affordable. Better for
citizens. Palacios. Has staff looked at
Lacey table? [Madani: Lacey proposal
is a reversal to staff recommendation. Would change how code considers
existing buildings. Additional cost not considered. TAC has approved this as
a glitch] Does Lacey table match statute? [Anderson-Adams: depends on which
part of the statute, 30% or building systems/components.] [Madani: Re in sink with FL statute, staff recommendation, Yes. Lacey:
No] Boyer: What would it take to
get an AG opinion? Richmond: Chair could ask for
one. Not fast. Scherer Agree with Lacey
proposal, question of Lacey, through Chair. What about other new
requirements. Lacey: Other costs need to be met irrespective of
cost. First time Gregory: Respond to Lacey’s suggestion that windows are systems. Don’t think
so. Gregory: Move to accept
staff’s recommendation, second Hamrick. Stone: will vote against motion;
don’t believe it is a glitch. In favor: 10; opposed 4. Motion fails. Stone, move to reconsider if
it is a glitch. Aye:
6, Nay: 8. Fails. Franco: Move to send back to
TAC to come up with a technical recommendation to reconcile differences in
table. Shearer: If do this, building
officials have no guidance as to whether to enforce. Aye:
13, Oppose, 1. Passes. |

TAC –May 24, 2012- Comment Jon – do not see this as a glitch. The code states what was intended. Greiner – does not need to add definition of
renovation – but because of action on Dec. statement this does provide
clarification. Phillip – unable to attend last meeting – Mo – Dec. was reviewed and TAC affirmed first
action taken in march that window replacement does fall under the 30%
rule. Consistent with action taken by
TAC at meeting on 5/14/2012. Cochell – that
this is a glitch Wojcieszak 2nd. Vote – Greiner
- y Cochell - y Fairey - n Jan -
n Palacios – y
Sanders -
y Wojcieszak - y 5-2 fails. Philip – re-write to limit number of windows
replaced (i.e. – if only one window replaced.) Jon – agrees with Phil. If changing all windows or almost all
windows should be brought up to code. 30% of
windows. Richmond – for those that voted no – how do
reconcile this vote with vote on item #1? Phil – this is written exclusively for
fenestration replacements only. Mo – must still go through chapter 1. Trying to further clarify to remove
confusion. Phil – 402.3.6 – replacement – specific to
windows and doors only. Mo – must read full code not take sections
separately. COMMISSION action –June
12, 2012 – Glitch (deferred) Note: send back to TAC for consideration [in
conjunction with 101.4.1] to make a technical evaluation. Public: Lacey: Recommend this not be acted on if Table
101.4 sent back to TAC. Nau: This section addresses how windows treated
in code. Looking for consistency. When TAC voted to remove HVAC from glitch,
argument reversed. Saw in same light. If HVAC covered by code, so should
windows. Belcher: Proposal solves problem seen by other
Commissioners, limits scope only to windows. TAC vote could have been
different because two TAC members left call. Hebrank: PGT
representative statement that this only applies to windows. Commission has
already broadened it to pool pumps. Stewart: Changing this has the opportunity to
become a nightmare. Wright: Agree with Lacey, this is directly
related to section 101.4.1. Commission action put 402.3.6 in place,
manufacturers spend millions to comply. Vieira: Attended the TAC meeting. Fairey felt this was not a glitch. -
(window
supplier). Should not be mandatory, need choice not to buy expensive windows.
Commission: Schock: Move
this is a glitch, Gonzalez second. Franco: Doesn’t seem to be a glitch. Aye
11, Nay 3. Passes. Gregory: Move to accept staff recommendation, Mollen second. Aye
3 Opposed 10 Fails Gregory, don’t see that windows are systems. Public comment: Dudley: Had a recommendation [didn’t pass] from
the TAC that not a glitch. TAC did not make recommendation on technical
issue. Hammond:
TAC didn’t make recommendation. Richmond:
Staff recommendation still up for consideration. Shock:
Move to send back to TAC for consideration [in conjunction with
101.4.1] to make a technical evaluation and bring back to Commission,
second. Aye unanimous. Gregory: Move take TAC meet face to face,
Palacios second. Aye unanimous. Dudley:
Tried to get TAC face to face before. It didn’t happen. Richmond:
Did have face to face in Tallahassee with teleconference option. May
have prevented members from attending. Electronic means for TAC and public to
participate. Palacios: Attending a meeting in Tallahassee is
terrible for a meeting. Browdy: Recommend meet in Tampa so all can attend.
Will work out details. |

Comment by R.W. Kicklighter. The
proposed exemption (#5) for buildings designed for dehumidification purposes
only has been in the Florida energy code for years. There are many buildings
used for the sole purpose of storage of materials or objects which are
sensitive to the high levels of humidity. Without an exemption for this type
of building, it is very difficult or impossible to meet the intent of the
FBC-Energy Conservation. |

1. Section 553.903, Florida
Statutes, Applicability, states:
“This part shall apply to all new
and renovated buildings in the state, except exempted buildings, for which
building permits are obtained after March 15, 1979, and to the installation or
replacement of building systems and components with new products for which
thermal efficiency standards are set by the Florida Energy Efficiency Code for
Building Construction.” [NOTE: 2 clauses]
2. Section 101.4.7 of the FBC-Energy Conservation, states:
“Thermal efficiency standards are set for the following building systems
where new products are installed or
replaced in existing building and for which a permit must be obtained. New
products shall meet the minimum efficiencies allowed by this code for the
following systems: Heating, ventilating
or air conditioning systems; Service water or pool heating systems; Electrical
systems and motors; Lighting systems.”
3. Sec. 553.902, Florida Statutes, defines RENOVATED BUILDING as “a residential or nonresidential building undergoing alteration that varies or changes insulation, HVAC systems, water heating systems, or exterior envelope conditions, provided the estimated cost of renovation exceeds 30 percent of the assessed value of the structure.” Section 202 of the FBC-Energy Conservation, further clarifies that the cost shall be cumulative over a 1 year period.
