(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) 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) 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) 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. Except as otherwise provided in this Act, the Code shall apply to (i) any new building or structure in this State for which a building permit application is received by a municipality or county and (ii) beginning on the effective date of this amendatory Act of the 100th General Assembly, each State facility specified in Section 4.01 of the Capital Development Board 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 3125/25) Sec. 25. Technical assistance. (a) The Department shall make available to builders, designers, engineers, and architects implementation materials and training to explain the requirements of the Code and describe methods of compliance acceptable to Code Enforcement Officials. (b) The materials shall include software tools, simplified prescriptive options, and other materials as appropriate. The simplified materials shall be designed for projects in which a design professional may not be involved. (c) The Department shall provide local jurisdictions with technical assistance concerning implementation and enforcement of the Code. (Source: P.A. 97-1033, eff. 8-17-12.)

(20 ILCS 3125/30) Sec. 30. Enforcement. The Board, in consultation with the Department, shall determine procedures for compliance with the Code. These procedures may include but need not be limited to certification by a national, State, or local accredited energy conservation program or inspections from private Code-certified inspectors using the Code. (Source: P.A. 93-936, eff. 8-13-04.)

(20 ILCS 3125/35) Sec. 35. Rules. The Board may adopt any rules that are necessary for the furtherance of this Act. (Source: P.A. 93-936, eff. 8-13-04.)

(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 10.18 of the Capital Development Board 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.
