Current through Register Vol. 24-14, July 15, 2024
7.1
Building
			 activity type and energy targets.
7.1.1
Building activity type.
Buildings
are divided into activity types as shown in Table
			 7-1 Normative Annex Z. Building activity types are defined by the
AHJ
in Table 7-4.
7.1.2
Energy targets.
Energy
			 targets for each building activity type are listed in Table 7.2a, Normative
			 Annex Z.
7.1.3
Building
			 operating shifts normalization factors.
Building
operating shifts normalization factors for each building activity type are
			 listed in Table 7-3, Normative Annex Z.
7.2.1 For
Tier 1 covered
			 buildings
the
qualified person
or for
Tier 2
			 covered building
the
qualified energy manager
shall
			 determine the
energy use intensity target
			 (EUIt)
according to Section 7.2.2 for
			 single-type/activity
buildings
and Section 7.2.3 for mixed-use
buildings
, and shall complete Form B.
Note:
Covered buildings
pursuing compliance
						  at the
connected building
level shall determine the
EUI
at the
connected building
level.
Exceptions to 7.2.1:
1.
Tier 2 covered buildings
unable to develop
EUI
in accordance with Section 7.2.2 or 7.2.3
			 of this standard shall report Energy Star portfolio manager median site
EUI
.
2.
			 EUIt programs developed and implemented by the
building's
local government and approved as equivalent or more
			 stringent by the
AHJ
may be used as an alternative to the
			 requirement in Section 7.2.1.
7.2.1.1 Additional target for more recently
			 built buildings: In addition to the requirements of section 7.2.1,
more
			 recently built buildings
shall create a second
EUIt
that is 15 percent less than the
			 target developed for compliance with section 7.2.1. This shall be the
building EUIt
and shall be included on
			 Form B.
7.2.2 Energy
			 targets for
buildings
with a single activity shall be
			 calculated as follows:

where
				(
EUIt
1) is the
building
activity energy target value in Table 7-2a for the
				appropriate
building
activities/types and climate, and
S
is the
building
operating shifts
				normalization factor in Table 7-3.
7.2.3 Energy targets for
buildings
with multiple activities shall be determined using weighted averages
			 of
building
activity energy target for each area with a single
			 activity, per the following equation, and reported on Normative Annex C Form B:

Exceptions to 7.2.3:
The
energy use
				intensity target (EUIt)
of a
building
may be modified using the following exceptions. None of these
				exceptions may be used to change the total
gross floor area
as
				it applies to Normative Annex Z, Z3.1 Compliance schedule.
1. Spaces where more than 75 percent of the
gross floor area
has a single
building
activity listed in Table 7-1 shall be reported as a single-use
building
or as a multiuse
building
in
			 accordance with either Section 7.2.2 or Section 7.2.3
2. Spaces less than 10 percent of the
gross floor area
with
building
activity
			 listed in Table 7-1 can combine their floor area with the floor area within the
building
that has a similar
building
activity
			 and similar
EUIt
as determined by the
qualified person.
3. Spaces in buildings with multiple
			 activities that are not listed in Table 7-1 and have a total combined area
			 [SIGMA]
Anontarget
comprising less than
			 10 percent of the
building gross floor area
			 Agross
can be excluded from
building
energy target calculations if the energy use of such
			 space is metered separately and the nontarget spaces comply with Sections 4.1
			 and 4.2. The energy target for the remaining part of the
building
shall be calculated after deducting the unlisted
building
type floor area from the
building gross floor
			 area
(
Agross
-[SIGMA]
Anontarget
).
			 Nontarget spaces shall be limited to the floor area occupied by the nontarget
			 activity and shall not include supporting spaces such as corridors, common
			 areas or other space types listed in Table 7-1.
4. Spaces in buildings with multiple
			 activities that are not listed in Table 7-1 and have a total combined area
			 [SIGMA]
Anontarget
comprising less than
			 50 percent of the
building gross floor area
			 Agross
can be excluded from
building
energy target calculations if the energy use of such
			 space is metered separately and the nontarget spaces comply with Sections 4.1,
			 4.2, 4.3.1, and 4.3.3. The energy target for the remaining part of the
building
shall be calculated after deducting the unlisted
building
type floor area from the
building gross floor
			 area
(
Agross
-[SIGMA]
Anontarget
).
			 Nontarget spaces shall be limited to the floor area occupied by the nontarget
			 activity and shall not include supporting spaces such as corridors, common
			 areas or other activity types listed in Table 7-1.
7.2.4
Energy targets for vacant and
			 partially vacant buildings.
Exception to 7.2.4 Vacant and partially vacant
				buildings:
If the
building
did not have
physical
				occupancy
by owner or tenant for at least 50 percent of the
				conditioned floor area throughout the consecutive 12-month period prior to the
building
compliance date, the
building owner
may apply for an exemption as specified in Normative Annex Z.
7.2.4.1 The energy target for vacant spaces
			 shall be based on its pre-vacancy activity if the intended use of the
building
will be unchanged.
7.2.4.2 If the total floor area of a
			 nonheated, noncooled, and nonilluminated vacant part of a
building
is smaller than 30 percent of the
gross floor
			 area
, then it shall be excluded from the
gross floor
			 area
, and the energy target shall be determined based on the remainder
			 of the
building
as described in Section 7.2.3. This allowance
			 may not be used to change the total
gross floor area
as it
			 applies to Normative Annex Z, Z3.1 Compliance schedule.
7.2.4.3 If the vacant part of a
building
is heated and/or cooled and the
building
energy use data for 12 consecutive month period when
			 the
building
was occupied within two years prior to the
			 compliance date is not available, compliance for this part of the
building
will be determined after it becomes occupied and
			 energy use data for 12 consecutive months becomes available.
