A. Scope
This Section establishes criteria for the design of buildings
in terms of the building's annual energy usage.
B. Analysis Criteria
1. Compliance with this Section requires an
analysis of the annual space conditioning energy usage, hereafter called
"energy usage", of the proposed building design and a comparison of such usage
with the energy usage of a standard building design.
2. A proposed building design will be deemed
to meet the requirements of
10 MRSA
§1415-G(3) if the
energy usage of the proposed building design is not greater than that of a
standard building design. The standard design shall be based on the criteria
specified by 10 MRSA14153), and this rule for insulation levels, infiltration
controls, and ventilation.
3. The
standard building design shall be substantially identical to the proposed
building design in the following respects:
a
Function and design requirements;
b
Size, shape, geometry, and orientation;
c Operating schedule, temperature, humidity,
ventilation and footcandles; and
d
Internal heat gains from occupants and equipment.
C. Analysis Procedure
1. The energy usage of the standard building
design and the proposed building design shall be determined through use of
identical energy analysis procedures.
a The
energy usage shall be expressed as total Btu usage per year of conditioned
floor area for both the proposed building design and the standard building
design.
b The energy usage from
various energy sources shall be converted to Btu per year of conditioned floor
area for the purposes of comparing the annual energy usage.
2. The analysis procedure shall
account for the operation of the building and its systems through a full year
operating period.
3. The analysis
of the annual energy usage of the standard building design and the proposed
building design shall be based on the same outdoor weather conditions including
temperatures, solar radiation, wind, and humidity of typical days in the year
representing seasonal variation.
D. Documentation
The analysis of the annual energy usage of the proposed
building design and the standard building design shall be prepared by a
licensed architect, engineer, or State certified energy auditor. The analysis
shall provide technical data on the proposed building design, the standard
building design, and the data used to verify that the requirements of this
Standard are met.
