OVERVIEW
AND PROJECT SCOPE
Governor Crist directed
the Commission to increase building energy efficiency requirements by 15% in
his July 2007 Executive Order 127. In addition, the 2008 Legislature through
passage of The
Energy Act of 2008 created a suite of energy related assignments for the
Building Commission. The Energy Code provisions were a major focus of the
Commission during 2008, and the Commission increased the thermal efficiency
requirements for the Florida Energy Code by 15% and integrated the enhanced
requirements into the 2007 Florida Building Code. The Commission reviewed
energy related code amendments adopted in the 2007 Florida Building Code Update
to determine their cumulative level of increased efficiency, and adopted
additional amendments required to achieve Governor Crist’s directive of 15%
increased efficiency. During 2008 the Energy Code was amended by administrative
rule and then the revised Energy Code was adopted into the 2007 Florida
Building Code during the 2008 “glitch” cycle concurrently with the March 1,
2009 effective date for the 2007 Florida Building Code. Working with stakeholders using
consensus-building workgroups, the Commission was able to achieve the 15%
increase in efficiency in buildings and implement code amendments that are
efficient, consistent, understandable and enforceable for the full spectrum of
Energy Code users.
The Commission’s Energy
Code Workgroup will develop recommendations regarding energy conservation
measures for increasing efficiency requirements in the 2010 FBC by 20% as
required by law.
Study Energy Conservation Measures and Develop a
Plan for 20% Increased Efficiency Requirement for 2010 FBC
Section 109, HB 7153
establishes a schedule for increases in building energy efficiency
requirements. This task expands the study of energy conservation measures for
residential buildings to investigation of efficiency options for commercial
buildings and the development of a plan to implement the requirements of the
new law. Section 553.9061 “Scheduled increases in thermal efficiency
standards.” was created to establish percent increases in efficiency to be
implemented in the 2010, 2013, 2016 and 2019 Code.
With the adoption of the
Glitch Amendments to the 2007 Edition of the Florida Building Code and the
revisions to Rule 9B-13 Thermal Efficiency Standards, the Commission
implemented a strategy for increasing the energy efficiency provisions of the
Code by 15%. The Commission’s Energy Code Workgroup and Energy TAC are working
with stakeholder to evaluate options for achieving an additional 5% increase
for the 2010 Edition of the Code, and for achieving the progressive increases
in efficiency required for subsequent editions of the code.
Develop Design Criteria for Energy Efficient Pool Systems
The Energy act of 2008
(HB 7135) directs adoption of pool pump efficiencies in the 2010 Code. During discussions with
the Florida Spa and Pool Association regarding energy efficiency requirements
for pool pumps members suggested improved efficiency could be achieved through
criteria for pool hydronic system design. This initiative would be conducted in coordination
with the national industry and other state’s initiatives currently underway.

ü
Offer one
idea per person without explanation.
ü
No comments,
criticism, or discussion of other's ideas.
ü
Listen
respectively to other's ideas and opinions.
ü
Seek
understanding and not agreement at this point in the discussion.
THE NAME STACKING PROCESS
ü
Determines
the speaking order.
ü
Participant
raises hand to speak. Facilitator(s) will call on participants in turn.
ü
Facilitator(s)
may interrupt the stack (change the speaking order) in order to promote
discussion on a specific issue or, to balance participation and allow those who
have not spoken on an issue an opportunity to do so before others on the list
who have already spoken on the issue.
ACCEPTABILITY RANKING SCALE
During the meetings,
members will be asked to develop and rank options, and following
discussions and
refinements, may be asked to do additional rankings of the options if requested
by members and staff. Please be prepared to offer specific refinements or
changes to address your reservations. The following scale will be utilized for
the ranking exercises:
SUBCOMMITTEE’S
CONSENSUS PROCESS
The Subcommittee will
seek to develop a package of consensus-based recommendations for submittal to
the Florida Energy Code Workgroup.
General consensus is a participatory process whereby, on matters of
substance, the members strive for agreements which all of the members can
accept, support, live with or agree not to oppose. In
instances where, after vigorously exploring possible ways to enhance the
members’ support for the final decision on a recommendation, and the
Subcommittee finds that 100% acceptance or support is not achievable, final
decisions will require at least 75% favorable vote of all members present and
voting. This super majority decision
rule underscores the importance of actively developing consensus throughout the
process on substantive issues with the participation of all members and which
all can live with. In instances where
the Subcommittee finds that even 75% acceptance or support is not achievable,
publication of recommendations will include documentation of the differences
and the options that were considered for which there is more than 50% support
from the Subcommittee.
The Subcommittee will
develop its recommendations using consensus-building techniques with the
assistance of the facilitator.
Techniques such as brainstorming, ranking and prioritizing approaches
will be utilized. Where differences
exist that prevent the Subcommittee from reaching a final consensus decision
(i.e. with support of at least 75% of the members) on a recommendation, the
Subcommittee will outline the differences in its documentation.
The Subcommittee’s
consensus process will be conducted as an open process consistent with
applicable law. Subcommittee members,
staff, and facilitator will be the only participants seated at the table. Only
Subcommittee members may participate in discussions and vote on proposals and
recommendations. The facilitator, or a Subcommittee member through the
facilitator, may request specific clarification from a member of the public in
order to assist the Subcommittee in understanding an issue. Observers/members
of the public are welcome to speak during the public comment period provided at
each meeting, and all comments submitted on the public comment forms provided
in the agenda packets will be included in the facilitator’ summary reports.
Facilitator will work
with staff and Subcommittee members to design agendas and worksheets that will
be both efficient and effective. The
staff will help the Subcommittee with information and meeting logistics.
To enhance the
possibility of constructive discussions as members educate themselves on the
issues and engage in consensus-building, members agree to refrain from public
statements that may prejudge the outcome of the Subcommittee’s consensus
process. In discussing the Subcommittee
process with the media, members agree to be careful to present only their own
views and not the views or statements of other participants. In addition, in
order to provide balance to the Subcommittee process, members agree to
represent and consult with their stakeholder interest groups.
