Illinois Compiled Statutes

Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

EXECUTIVE BRANCH
(20 ILCS 3125/) Energy Efficient Building Act.

20 ILCS 3125/1

    (20 ILCS 3125/1)
    Sec. 1. Short title. This Act may be cited as the Energy Efficient Building Act.
(Source: P.A. 96-778, eff. 8-28-09.)

20 ILCS 3125/5

    (20 ILCS 3125/5)
    Sec. 5. Findings.
    (a) The legislature finds that an effective energy efficient building code is essential to:
        (1) reduce the air pollutant emissions from energy
    
consumption that are affecting the health of residents of this State;
        (2) moderate future peak electric power demand;
        (3) assure the reliability of the electrical grid and
    
an adequate supply of heating oil and natural gas; and
        (4) control energy costs for residents and businesses
    
in this State.
    (b) The legislature further finds that this State has a number of different climate types, all of which require energy for both cooling and heating, and that there are many cost-effective measures that can reduce peak energy use and reduce cooling, heating, lighting, and other energy costs in buildings.

20 ILCS 3125/15

    (20 ILCS 3125/15)
    Sec. 15. Energy Efficient Building Code. The Board, in consultation with the Department, shall adopt the Code as minimum requirements for commercial buildings, applying to the construction of, renovations to, and additions to all commercial buildings in the State. The Board, in consultation with the Department, shall also adopt the Code as the minimum and maximum requirements for residential buildings, applying to the construction of all residential buildings in the State, except as provided for in Section 45 of this Act. The Board may appropriately adapt the International Energy Conservation Code to apply to the particular economy, population distribution, geography, and climate of the State and construction therein, consistent with the public policy objectives of this Act.
(Source: P.A. 96-778, eff. 8-28-09.)

20 ILCS 3125/20

    (20 ILCS 3125/20)
    Sec. 20. Applicability.
    (a) The Board shall review and adopt the Code within one year after its publication. The Code shall take effect within 6 months after it is adopted by the Board, except that, beginning January 1, 2012, the Code adopted in 2012 shall take effect on January 1, 2013, and shall apply to any new building or structure in this State for which a building permit application is received by a municipality or county, except as otherwise provided by this Act. In the case of any addition, alteration, renovation, or repair to an existing commercial structure, the Code adopted under this Act applies only to the portions of that structure that are being added, altered, renovated, or repaired. The changes made to this Section by this amendatory Act of the 97th General Assembly shall in no way invalidate or otherwise affect contracts entered into on or before the effective date of this amendatory Act of the 97th General Assembly.
    (b) The following buildings shall be exempt from the Code:
        (1) Buildings otherwise exempt from the provisions of
    
a locally adopted building code and buildings that do not contain a conditioned space.
        (2) Buildings that do not use either electricity or
    
fossil fuel for comfort conditioning. For purposes of determining whether this exemption applies, a building will be presumed to be heated by electricity, even in the absence of equipment used for electric comfort heating, whenever the building is provided with electrical service in excess of 100 amps, unless the code enforcement official determines that this electrical service is necessary for purposes other than providing electric comfort heating.
        (3) Historic buildings. This exemption shall apply
    
to those buildings that are listed on the National Register of Historic Places or the Illinois Register of Historic Places, and to those buildings that have been designated as historically significant by a local governing body that is authorized to make such designations.
        (4) (Blank).
        (5) Other buildings specified as exempt by the
    
International Energy Conservation Code.
    (c) Additions, alterations, renovations, or repairs to an existing building, building system, or portion thereof shall conform to the provisions of the Code as they relate to new construction without requiring the unaltered portion of the existing building or building system to comply with the Code. The following need not comply with the Code, provided that the energy use of the building is not increased: (i) storm windows installed over existing fenestration, (ii) glass-only replacements in an existing sash and frame, (iii) existing ceiling, wall, or floor cavities exposed during construction, provided that these cavities are filled with insulation, and (iv) construction where the existing roof, wall, or floor is not exposed.
    (d) A unit of local government that does not regulate energy efficient building standards is not required to adopt, enforce, or administer the Code; however, any energy efficient building standards adopted by a unit of local government must comply with this Act. If a unit of local government does not regulate energy efficient building standards, any construction, renovation, or addition to buildings or structures is subject to the provisions contained in this Act.

20 ILCS 3125/45

    (20 ILCS 3125/45)
    Sec. 45. Home rule.
    (a) No unit of local government, including any home rule unit, may regulate energy efficient building standards for commercial buildings in a manner that is less stringent than the provisions contained in this Act.
    (b) No unit of local government, including any home rule unit, may regulate energy efficient building standards for residential buildings in a manner that is either less or more stringent than the standards established pursuant to this Act; provided, however, that the following entities may regulate energy efficient building standards for residential buildings in a manner that is more stringent than the provisions contained in this Act: (i) a unit of local government, including a home rule unit, that has, on or before May 15, 2009, adopted or incorporated by reference energy efficient building standards for residential buildings that are equivalent to or more stringent than the 2006 International Energy Conservation Code, (ii) a unit of local government, including a home rule unit, that has, on or before May 15, 2009, provided to the Capital Development Board, as required by Section 55 of the Illinois Building Commission Act, an identification of an energy efficient building code or amendment that is equivalent to or more stringent than the 2006 International Energy Conservation Code, and (iii) a municipality with a population of 1,000,000 or more.
    (c) No unit of local government, including any home rule unit or unit of local government that is subject to State regulation under the Code as provided in Section 15 of this Act, may hereafter enact any annexation ordinance or resolution, or require or enter into any annexation agreement, that imposes energy efficient building standards for residential buildings that are either less or more stringent than the energy efficiency standards in effect, at the time of construction, throughout the unit of local government.
    (d) This Section is a denial and limitation of home rule powers and functions under subsection (i) of Section 6 of Article VII of the Illinois Constitution on the concurrent exercise by home rule units of powers and functions exercised by the State. Nothing in this Section, however, prevents a unit of local government from adopting an energy efficiency code or standards for commercial buildings that are more stringent than the Code under this Act.
