Task/Analysis:
Sub-Task 1:
- Identify compliance methods used in current national
model and Florida
energy code
- Describe how the compliance methods work
Sib-Task 2:
- Create a matrix of IECC and FEECBC characteristics
for each method
- Evaluate for flexibility to implement future
efficiency increases
Sub-Task 3:
- Select compliance method characteristics that provide
the maximum potential to implement the 553.9061 mandated efficiency
increases to form the strategic plan

(b) How the Compliance Methods Work –
Note:
Each Code/Standard has a little different way of implementing
the major
compliance methods, which will be identified in the
matrices.
Prescriptive:
- Provides minimum efficiency
criteria for building components that contribute to energy use
- Does not allow trade off of
increased efficiency of one component for lower efficiency of another
- Simple with uniform
requirements for efficiency of components for all similar buildings
- May or may not require equal
overall efficiency for buildings with different building features and construction
types
- …
- …
Performance:
- Establishes an overall energy
efficiency target (or translated energy cost budget) for the entire building
- Allows trade off of
efficiencies between components to achieve the overall efficiency target
- Requires calculation of overall
building energy use to determine the appropriate trade off between
component efficiencies
- May or may not require equal
overall efficiency for buildings with different building features and
construction types
- …
- …
Component
Performance:
- Provides minimum efficiency
criteria for HVAC equipment, water heating equipment and lighting
components (commercial)
- Allows trade off of
efficiencies between building envelope components based on R/U values
- Does not allow trade off for
window solar control properties
- A hybrid of the prescriptive
and performance methods that is traditionally appropriate to heating
dominated climates where air to air heat transfer is more significant
