AMENDMENT TO HOUSE BILL 3510

2    AMENDMENT NO. ______. Amend House Bill 3510 by replacing 
3everything after the enacting clause with the following:
 
4    "Section 5. The Energy Efficient Building Act is amended 
5by 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 
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 
 
 
10400HB3510ham002- 2 -LRB104 10624 HLH 25148 a

1that adopts the Illinois Stretch Energy Code.
2    (b) The Illinois Stretch Energy Code shall have separate 
3components for commercial and residential buildings, which may 
4be adopted by the municipality jointly or separately.
5    (c) The Illinois Stretch Energy Code shall apply to all 
6projects to which an energy conservation code is applicable 
7that are authorized or funded in any part by the Board after 
8July 1, 2024.
9    (d) Development of the Illinois Stretch Energy Code shall 
10be completed and available for adoption by municipalities by 
11June 30, 2024.
12    (e) Consistent with the requirements under paragraph (2.5) 
13of subsection (g) of Section 8-103B of the Public Utilities 
14Act and under paragraph (2) of subsection (j) of Section 8-104 
15of the Public Utilities Act, municipalities may adopt the 
16Illinois Stretch Energy Code and may use utility programs to 
17support compliance with the Illinois Stretch Energy Code. The 
18amount of savings from such utility efforts that may be 
19counted toward achievement of their annual savings goals shall 
20be based on reasonable estimates of the increase in savings 
21resulting from the utility efforts, relative to reasonable 
22approximations of what would have occurred absent the utility 
23involvement.
24    (f) The Illinois Stretch Energy Code's residential 
25components shall:
26        (1) apply to residential buildings as defined under 
 
 
10400HB3510ham002- 3 -LRB104 10624 HLH 25148 a

1    Section 10;
2        (2) set performance targets using a site energy index 
3    with reductions relative to the 2006 International Energy 
4    Conservation Code; and
5        (3) include stretch energy codes with site energy 
6    index standards and adoption dates as follows: by no later 
7    than June 30, 2024, the Board shall create and adopt a 
8    stretch energy code with a site energy index no greater 
9    than 0.50 of the 2006 International Energy Conservation 
10    Code; by no later than December 31, 2026 December 31, 
11    2025, the Board shall create and adopt a stretch energy 
12    code with a site energy index no greater than 0.40 of the 
13    2006 International Energy Conservation Code, unless the 
14    Board identifies unanticipated burdens associated with the 
15    stretch energy code adopted in 2023 or 2024, in which case 
16    the Board may adopt a stretch energy code with a site 
17    energy index no greater than 0.42 of the 2006 
18    International Energy Conservation Code, provided that the 
19    more relaxed standard has a site energy index that is at 
20    least 0.05 more restrictive than the 2024 International 
21    Energy Conservation Code; by no later than December 31, 
22    2029 December 31, 2028, the Board shall create and adopt a 
23    stretch energy code with a site energy index no greater 
24    than 0.33 of the 2006 International Energy Conservation 
25    Code, unless the Board identifies unanticipated burdens 
26    associated with the stretch energy code adopted in 2025, 
 
 
10400HB3510ham002- 4 -LRB104 10624 HLH 25148 a

1    in which case the Board may adopt a stretch energy code 
2    with a site energy index no greater than 0.35 of the 2006 
3    International Energy Conservation Code, but only if that 
4    more relaxed standard has a site energy index that is at 
5    least 0.05 more restrictive than the 2027 International 
6    Energy Conservation Code; and by no later than December 
7    31, 2032 December 31, 2031, the Board shall create and 
8    adopt a stretch energy code with a site energy index no 
9    greater than 0.25 of the 2006 International Energy 
10    Conservation Code.
11    (g) The Illinois Stretch Energy Code's commercial 
12components shall:
13        (1) apply to commercial buildings as defined under 
14    Section 10;
15        (2) set performance targets using a site energy index 
16    with reductions relative to the 2006 International Energy 
17    Conservation Code; and
18        (3) include stretch energy codes with site energy 
19    index standards and adoption dates as follows: by no later 
20    than June 30, 2024, the Board shall create and adopt a 
21    stretch energy code with a site energy index no greater 
22    than 0.60 of the 2006 International Energy Conservation 
23    Code; by no later than December 31, 2026 December 31, 
24    2025, the Board shall create and adopt a stretch energy 
25    code with a site energy index no greater than 0.50 of the 
26    2006 International Energy Conservation Code; by no later

1    than December 31, 2029 December 31, 2028, the Board shall 
2    create and adopt a stretch energy code with a site energy 
3    index no greater than 0.44 of the 2006 International 
4    Energy Conservation Code; and by no later than December 
5    31, 2032 December 31, 2031, the Board shall create and 
6    adopt a stretch energy code with a site energy index no

8    Conservation Code.
9    (h) The process for the creation of the Illinois Stretch 
10Energy Code includes:
11        (1) within 60 days after the effective date of this 
12    amendatory Act of the 102nd General Assembly, the Capital 
13    Development Board shall meet with the Illinois Energy Code

15    assistance and recommendations to the Capital Development 
16    Board for the Illinois Stretch Energy Code, which shall:
17            (A) advise the Capital Development Board on
