Each major facility project must be designed, constructed, and certified to exceed the requirements of the state energy code by at least 30 percent. Such improvements must also prove to be cost effective based on a life cycle cost analysis with a payback of no more than 30 years. Until December 31, 2008, this requirement applied to all new projects larger than 20,000 gross square feet.
Size requirements for future projects required to meet the standard are applied as follows:
- From January 1, 2009 through December 31, 2009 -- projects larger than 15,000 square feet
- From January 1, 2010 through December 31, 2010 -- projects larger than 10,000 square feet
- From January 1, 2011 and thereafter -- projects larger than 5,000 square feet
- The standard also applies to major renovation projects which involve more than 50% of the replacement value of the facility or a change in occupancy. Public Building Energy Standard, 2007.
Adoption is through legislation for commercial buildings and local ordinance for Use Group R-3. Local government is allowed to adopt only the state commercial energy code.
The Office of the State Fire Marshal is granted the authority to promulgate amendments, revisions, and alternative compliance methods for the code. Once promulgated, they would replace the existing code.
The State Fire Marshal and Facility Planning and Control Section of the Division of Administration have authority to promulgate rules and regulations necessary to enforce the provisions of the legislation. These rules and regulations are currently being formulated.
A local government may adopt and enforce its own commercial building energy conservation code; however, it must be the state's commercial building energy conservation code.
The Office of the State Fire Marshal has authority to enforce the code for commercial buildings statewide except state-owned commercial buildings. Plans, specifications, and energy code compliance documents must be submitted to and reviewed by the State Fire Marshal. The submitter will receive a letter from the State Fire Marshal indicating whether the documents demonstrate compliance. Receipt of the letter cannot delay the State Fire Marshal's normal project review process, nor the ability of a local building department to issue a building permit or use and occupancy permit.
Parties receiving a letter of non-compliance can resubmit revised plans and will be issued another letter notifying them of compliance or non compliance. Any compliance letters must be kept at the building site and the owners must retain the letter once the structure is occupied.
For state-owned facilities, the Facility Planning and Control Section of the Division of Administration has authority. They must determine that plans, specifications, and energy code compliance documents comply with the code, as well as all alterations and repairs.
The state adopted the 1991 Standard Building Code (SBC) state-wide and any future revisions to the SBC. Appendix E of this code (dealing with energy in buildings) was not adopted, but cities and parishes could adopt this portion of the code. Appendix E required adherence to the 1989 MEC with an option to use ASHRAE/IESNA 90.1-1989 for buildings other than residential buildings three stories high or less, and ASHRAE/IES Standard 90A-1980 for residential buildings three stories high or less.
During the 1997 regular session of the legislature, Senate Bill No. 1167 was passed and enacted. This act created a new Part IV-B of Chapter 8 of Title 40 of the Louisiana Revised Statutes. The purpose of the legislation is to institute minimum energy conservation standards for all new commercial construction and all applicable alterations and repairs in commercial buildings. The legislation was passed in June 1997, signed by the governor on July 14, 1997, and became effective on January 1, 1999. The legislation also establishes requirements for education and training and an Advisory Committee.
As of January 1, 2007, ACT 12 mandates that the 2006 IRC is effective state-wide for one to two family homes. The bill also created the Louisiana State Uniform Construction Council to review and adopt the state uniform construction code.
In 2010, the Louisiana State Uniform Construction Code Council voted to retain Chapter 11 from the 2006 IRC. The 2009 IRC with Chapter 11/2006 IRC became effective Jan. 1, 2011.
The Louisiana Office of the State Fire Marshal has initiated the process to update the Commercial Building Energy Conservation Code to ASHRAE 90.1-2007 which went into effect on July 20, 2011.
Louisiana Uniform Construction Code amended the following: "Substitute Chapter 11, Energy Efficiency of the 2009 IRC, in lieu of Chapter 11 Energy Efficiency of the 2012 IRC", one- and two- family suppplement to the 2006 IMC with the 2012 IRC Part V-Mechanical, and Appendix G of the 2012 IRC.
