Sec. 55.
Illinois Stretch Energy Code.
7

(a) The Board, in consultation with the Agency, shall
8
create and adopt the Illinois Stretch Energy Code, to allow
9
municipalities and projects authorized or funded by the Board
10
to achieve more energy efficiency in buildings than the
11
Illinois Energy Conservation Code through a consistent pathway
12
across the State. The Illinois Stretch Energy Code shall be
13
available for adoption by any municipality and shall set
14
minimum energy efficiency requirements, taking the place of
15
the Illinois Energy Conservation Code within any municipality
16
that adopts the Illinois Stretch Energy Code.
17

(b) The Illinois Stretch Energy Code shall have separate
18
components for commercial and residential buildings, which may
19
be adopted by the municipality jointly or separately.
20

(c) The Illinois Stretch Energy Code shall apply to all
21
projects to which an energy conservation code is applicable
22
that are authorized or funded in any part by the Board after
23
July 1, 2024.
24

(d) Development of the Illinois Stretch Energy Code shall
25
be completed and available for adoption by municipalities by

3
of subsection (g) of Section 8-103B of the Public Utilities
4
Act and under paragraph (2) of subsection (j) of Section 8-104
5
of the Public Utilities Act, municipalities may adopt the
6
Illinois Stretch Energy Code and may use utility programs to
7
support compliance with the Illinois Stretch Energy Code. The
8
amount of savings from such utility efforts that may be
9
counted toward achievement of their annual savings goals shall
10
be based on reasonable estimates of the increase in savings
11
resulting from the utility efforts, relative to reasonable
12
approximations of what would have occurred absent the utility
13
involvement.

(f) The Illinois Stretch Energy Code's residential
15
components shall:
16

(1) apply to residential buildings as defined under
17

Section 10;
