Introduction
Design Process Strategies
Core Performance Requirements
3.3 Additional Lighting Power Reductions
Enhanced Performance Strategies
Energy Modeling
Purp ose
To reduce connected lighting load to achieve the requirements of the Energy Policy Act of 2005
and qualify for Federal tax incentives.
Appendices
Criteria
Reduce connected lighting load by at least 40% below the allowances of the
ASHRAE 90.1 reference standard used by EPAct 05, while meeting all of the
lighting control requirements of that standard. (Note that EPAct05 uses the 2001
version of the ASHRAE 90.1 standard as a reference point, even though newer versions of
90.1 are in force.)
Gener al
Projects which meet the lighting power density (LPD) and control requirements
of Core Performance are well on their way to qualifying for federal tax incentives
under the Energy Policy act of 2005 (EPAct 05). An additional effort on the part of the design team
to reduce connected lighting load can result in eligibility of the project to receive tax incentives. For
tax-exempt public projects, the tax incentive can be transferred directly to the design team.
The basic requirements of EPAct 05 are to reduce LPD by 25% to 40% below the requirements
of ASHRAE 90.1-2001, and to implement the interior and exterior lighting control
requirements of that standard. Achieving this qualifies the project for a Federal tax deduction
of $0.30 to $0.60 per square foot of building
area under the current policy. (Increases in
Table 3. 3.1 - approx im ate LPD
the incentive level and program extensions are
requirement s for achie ving EPAC T05
currently under consideration; current program
40%
requirements should be verified.)
Lig hting
The goal of this Criteria is to achieve a 40%
reduction in connected lighting load (compared
to the EPAct 05 baseline) which represents
approximately a 20% reduction below the
a reduction of 10% or more from the
requirements listed in Criteria 2.8. Specific
targets are shown in the LPD table below, which
is derived from typical LPD requirements of
ASHRAE 90.1-2001 as listed in Table 9.3.1.1
of that standard and Criteria 2.8 of the Core
Performance Guide. Note that the values in
this table represent only a subset of building.
