Summary

In the City of Kingsport, Tennessee, energy efficiency rules come from the 2018 International Energy Conservation Code adopted in Section 22-96(d). The state minimum standard controls for one-family and two-family construction wherever the 2018 code is more stringent, Kingsport swaps in 2009 code tables, and blower door and duct blaster testing became optional effective March 1, 2024.

Full Breakdown

Kingsport's energy standards sit in Section 22-96(d), where the Board of Mayor and Aldermen adopted the International Energy Conservation Code, 2018 edition, by reference and then amended it in five numbered ways.

Amendment (1) deals with the State. To the extent the 2018 edition contains standards more stringent than the state minimum standards adopted by the state fire marshal for one-family and two-family construction and additions of 30 or more square feet of interior space, the state minimum standard applies. The section cites Tenn. Code Ann. § 68-120-101(b)(2)(A)(iii) (2023) and Tenn. Comp. R. & Regs. Chapter 0780-02-23 (2023), or as amended from time to time.

Amendments (2) and (3) add one sentence each to Section C109.1 (commercial) and Section R109.1 (residential): the Board of Appeals referenced in the International Building Code, 2018 edition, serves as the Board of Appeals for the Energy Conservation Code.

Amendment (4) replaces 2018 tables with tables from the 2009 edition. For example, the commercial opaque thermal envelope assembly table C402.1.4 gives way to 2009 table 502.1.2, the commercial fenestration table C402.4 to 502.3, and the residential insulation and fenestration by component table R402.1.2 to 402.1.1.

Amendment (5) makes the testing required by 402.4.2.1 (Blower Door) and 403.2.2 (Duct Blaster) optional effective March 1, 2024. The residential code amendment in Section 22-96(e)(6) deletes Chapter 11 Energy Conservation of the International Residential Code and replaces it with the 2018 Energy Code as adopted, with the same two tests optional from the same date.

The building official runs the building department and enforces the building codes under Section 22-49. The history note for Section 22-96 ends with Ord. No. 7136, § I, dated 2-20-2024, the ordinance that fits the March 1, 2024 date.

Violations & Fines

Section 22-96 prints no energy-code penalty of its own. Section 1-14 supplies the general penalty for a prohibited act with no specific penalty: not less than $10.00 or more than $50.00, unless state law permits a greater amount, with each day a violation continues counted as a separate offense unless the ordinance says otherwise. The amendment removes the mandatory status of the blower door and duct blaster tests effective March 1, 2024.

Frequently Asked Questions

Does Kingsport still require blower door and duct blaster tests?
No. Section 22-96(d)(5) says the testing required by 402.4.2.1 (Blower Door) and 403.2.2 (Duct Blaster) became optional effective March 1, 2024. The residential amendment in Section 22-96(e)(6) repeats that the R402.4.2.1 and R403.2.2 tests are optional from the same date in the City of Kingsport.
Which energy code edition does Kingsport use?
Kingsport adopted the International Energy Conservation Code, 2018 edition, but replaced a list of its tables with tables from the 2009 edition, including C402.1.4, C402.4, C403.3.2(1)(9), R402.1.2, R402.1.4 and R405.5.2(1). The 2009 tables are the ones that govern in those places.
What if the State minimum standard is different from the 2018 code?
For one-family and two-family construction and additions of 30 or more square feet of interior space, Section 22-96(d)(1) says the state minimum standard applies to the extent the 2018 edition contains standards more stringent than the state minimum adopted by the state fire marshal. The section cites Tenn. Code Ann. § 68-120-101(b)(2)(A)(iii).
Who hears an appeal on an energy code decision in Kingsport?
Sections C109.1 and R109.1 are amended so the Board of Appeals referenced in the International Building Code, 2018 edition, serves as the Board of Appeals for the International Energy Conservation Code, 2018 edition. The building official enforces the code as head of the building department under Section 22-49.
