HB3510 Enrolled                     LRB104 10624 HLH 20700 b

1   AN ACT concerning State government.

2   Be it enacted by the People of the State of Illinois,

3 represented in the General Assembly:

4   Section 5. The Energy Efficient Building Act is amended by

5 changing 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

9 create and adopt the Illinois Stretch Energy Code, to allow

10 municipalities and projects authorized or funded by the Board

11 to achieve more energy efficiency in buildings than the

12 Illinois Energy Conservation Code through a consistent pathway

13 across the State. The Illinois Stretch Energy Code shall be

14 available for adoption by any municipality and shall set

15 minimum energy efficiency requirements, taking the place of

16 the Illinois Energy Conservation Code within any municipality

17 that adopts the Illinois Stretch Energy Code.

18  (b) The Illinois Stretch Energy Code shall have separate

19 components for commercial and residential buildings, which may

20 be adopted by the municipality jointly or separately.

21  (c) The Illinois Stretch Energy Code shall apply to all

22 projects to which an energy conservation code is applicable

23 that are authorized or funded in any part by the Board after
    HB3510 Enrolled         -2-  LRB104 10624 HLH 20700 b

1 July 1, 2024.

2   (d) Development of the Illinois Stretch Energy Code shall

3 be completed and available for adoption by municipalities by

4 June 30, 2024.

5   (e) Consistent with the requirements under paragraph (2.5)

6 of subsection (g) of Section 8-103B of the Public Utilities

7 Act and under paragraph (2) of subsection (j) of Section 8-104

8 of the Public Utilities Act, municipalities may adopt the

9 Illinois Stretch Energy Code and may use utility programs to

10 support compliance with the Illinois Stretch Energy Code. The

11 amount of savings from such utility efforts that may be

12 counted toward achievement of their annual savings goals shall

13 be based on reasonable estimates of the increase in savings

14 resulting from the utility efforts, relative to reasonable

15 approximations of what would have occurred absent the utility

16 involvement.

17  (f) The Illinois Stretch Energy Code's residential

18 components 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 Enrolled  -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 December 31,

4   2025, the Board shall create and adopt a stretch energy

5   code with a site energy index no greater than 0.40 of the

6   2006 International Energy Conservation Code, unless the

7   Board 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 December 31, 2028, the Board shall create and adopt a

16  stretch energy code with a site energy index no greater

17  than 0.33 of the 2006 International Energy Conservation

18  Code, unless the Board identifies unanticipated burdens

19  associated with the stretch energy code adopted in 2025,

20  in which case the Board may adopt a stretch energy code

21  with a site energy index no greater than 0.35 of the 2006

22  International Energy Conservation Code, but only if that

23  more relaxed standard has a site energy index that is at

24  least 0.05 more restrictive than the 2027 International

25  Energy Conservation Code; and by no later than December

26  31, 2032 December 31, 2031, the Board shall create and
    HB3510 Enrolled         -4-  LRB104 10624 HLH 20700 b

1   adopt a stretch energy code with a site energy index no

2   greater than 0.25 of the 2006 International Energy

3   Conservation Code.

4   (g) The Illinois Stretch Energy Code's commercial

5 components shall:

6   (1) apply to commercial buildings as defined under

7   Section 10;

8   (2) set performance targets using a site energy index

9   with reductions relative to the 2006 International Energy

10  Conservation Code; and

11  (3) include stretch energy codes with site energy

12  index standards and adoption dates as follows: by no later

13  than June 30, 2024, the Board shall create and adopt a

14  stretch energy code with a site energy index no greater

15  than 0.60 of the 2006 International Energy Conservation

16  Code; by no later than December 31, 2026 December 31,

17  2025, the Board shall create and adopt a stretch energy

18  code with a site energy index no greater than 0.50 of the

19  2006 International Energy Conservation Code; by no later

20  than December 31, 2029 December 31, 2028, the Board shall

21  create and adopt a stretch energy code with a site energy

22  index no greater than 0.44 of the 2006 International

23  Energy Conservation Code; and by no later than December

24  31, 2032 December 31, 2031, the Board shall create and

25  adopt a stretch energy code with a site energy index no

26  greater than 0.39 of the 2006 International Energy

2   (h) The process for the creation of the Illinois Stretch

3 Energy Code includes:

4   (1) within 60 days after the effective date of this

5   amendatory Act of the 102nd General Assembly, the Capital

6   Development Board shall meet with the Illinois Energy Code

7   Advisory Council to advise and provide technical

8   assistance and recommendations to the Capital Development

9   Board for the Illinois Stretch Energy Code, which shall:

10  (A) advise the Capital Development Board on

12  requirements, and an implementation plan for the

13  Illinois Stretch Energy Code;

14  (B) recommend amendments to proposed rules issued

15  by the Capital Development Board;

16  (C) recommend complementary programs or policies;

17  (D) complete recommendations and development for
