A BILL FOR

 

HB3510LRB104 10624 HLH 20700 b

1    AN ACT concerning State government.
 
2    Be it enacted by the People of the State of Illinois,
3represented in the General Assembly:
 
4    Section 5. The Energy Efficient Building Act is amended by
5changing Section 55 as follows:
 
6    (20 ILCS 3125/55)
7    Sec. 55. Illinois Stretch Energy Code.
8    (a) The Board, in consultation with the Agency, shall
9create and adopt the Illinois Stretch Energy Code, to allow
10municipalities and projects authorized or funded by the Board
11to achieve more energy efficiency in buildings than the
12Illinois Energy Conservation Code through a consistent pathway
13across the State. The Illinois Stretch Energy Code shall be
14available for adoption by any municipality and shall set
15minimum energy efficiency requirements, taking the place of
16the Illinois Energy Conservation Code within any municipality
17that adopts the Illinois Stretch Energy Code.
18    (b) The Illinois Stretch Energy Code shall have separate
19components for commercial and residential buildings, which may
20be adopted by the municipality jointly or separately.
21    (c) The Illinois Stretch Energy Code shall apply to all
22projects to which an energy conservation code is applicable
23that are authorized or funded in any part by the Board after

 

 

HB3510- 2 -LRB104 10624 HLH 20700 b

1July 1, 2024.
2    (d) Development of the Illinois Stretch Energy Code shall
3be completed and available for adoption by municipalities by
4June 30, 2024.
5    (e) Consistent with the requirements under paragraph (2.5)
6of subsection (g) of Section 8-103B of the Public Utilities
7Act and under paragraph (2) of subsection (j) of Section 8-104
8of the Public Utilities Act, municipalities may adopt the
9Illinois Stretch Energy Code and may use utility programs to
10support compliance with the Illinois Stretch Energy Code. The
11amount of savings from such utility efforts that may be
12counted toward achievement of their annual savings goals shall
13be based on reasonable estimates of the increase in savings
14resulting from the utility efforts, relative to reasonable
15approximations of what would have occurred absent the utility
16involvement.
17    (f) The Illinois Stretch Energy Code's residential
18components shall:
19        (1) apply to residential buildings as defined under
20    Section 10;
21        (2) set performance targets using a site energy index
22    with reductions relative to the 2006 International Energy
23    Conservation Code; and
24        (3) include stretch energy codes with site energy
25    index standards and adoption dates as follows: by no later
26    than June 30, 2024, the Board shall create and adopt a

 

 

HB3510- 3 -LRB104 10624 HLH 20700 b

1    stretch energy code with a site energy index no greater
2    than 0.50 of the 2006 International Energy Conservation
3    Code; by no later than December 31, 2026 2025, the Board
4    shall create and adopt a stretch energy code with a site
5    energy index no greater than 0.40 of the 2006
6    International Energy Conservation Code, unless the Board
7    identifies unanticipated burdens associated with the
8    stretch energy code adopted in 2023 or 2024, in which case
9    the Board may adopt a stretch energy code with a site
10    energy index no greater than 0.42 of the 2006
11    International Energy Conservation Code, provided that the
12    more relaxed standard has a site energy index that is at
13    least 0.05 more restrictive than the 2024 International
14    Energy Conservation Code; by no later than December 31,
15    2029 2028, the Board shall create and adopt a stretch
16    energy code with a site energy index no greater than 0.33
17    of the 2006 International Energy Conservation Code, unless
18    the Board identifies unanticipated burdens associated with
19    the stretch energy code adopted in 2025, in which case the
20    Board may adopt a stretch energy code with a site energy
21    index no greater than 0.35 of the 2006 International
22    Energy Conservation Code, but only if that more relaxed
23    standard has a site energy index that is at least 0.05 more
24    restrictive than the 2027 International Energy
25    Conservation Code; and by no later than December 31, 2032
26    2031, the Board shall create and adopt a stretch energy

 

 

HB3510- 4 -LRB104 10624 HLH 20700 b

1    code with a site energy index no greater than 0.25 of the
2    2006 International Energy Conservation Code.
3    (g) The Illinois Stretch Energy Code's commercial
4components shall:
5        (1) apply to commercial buildings as defined under
6    Section 10;
7        (2) set performance targets using a site energy index
8    with reductions relative to the 2006 International Energy
9    Conservation Code; and
10        (3) include stretch energy codes with site energy
11    index standards and adoption dates as follows: by no later
12    than June 30, 2024, the Board shall create and adopt a
13    stretch energy code with a site energy index no greater
14    than 0.60 of the 2006 International Energy Conservation
15    Code; by no later than December 31, 2025, the Board shall
16    create and adopt a stretch energy code with a site energy
17    index no greater than 0.50 of the 2006 International
18    Energy Conservation Code; by no later than December 31,
19    2028, the Board shall create and adopt a stretch energy
20    code with a site energy index no greater than 0.44 of the
21    2006 International Energy Conservation Code; and by no
22    later than December 31, 2031, the Board shall create and
23    adopt a stretch energy code with a site energy index no
24    greater than 0.39 of the 2006 International Energy
25    Conservation Code.
26    (h) The process for the creation of the Illinois Stretch

 

 

HB3510- 5 -LRB104 10624 HLH 20700 b

1Energy Code includes:
2        (1) within 60 days after the effective date of this
3    amendatory Act of the 102nd General Assembly, the Capital
4    Development Board shall meet with the Illinois Energy Code
5    Advisory Council to advise and provide technical
6    assistance and recommendations to the Capital Development
7    Board for the Illinois Stretch Energy Code, which shall:
8            (A) advise the Capital Development Board on
9        creation of interim performance targets, code
10        requirements, and an implementation plan for the
11        Illinois Stretch Energy Code;
12            (B) recommend amendments to proposed rules issued
13        by the Capital Development Board;
14            (C) recommend complementary programs or policies;
15            (D) complete recommendations and development for
16        the Illinois Stretch Energy Code elements and

18        (2) As part of its deliberations, the Illinois Energy
19    Code Advisory Council shall actively solicit input from
20    other energy code stakeholders and interested parties.
