1.05. The Code is amended in Division A of Volume 1,

(1)  in Article 1.1.1.1., by replacing Sentences (1) to (3) by the following:

“(1) The NBC applies to the construction work performed on every building and facility intended for use by the public as provided in section 1.02 of Chapter I of the Construction Code made pursuant to the Building Act (chapter B-1.1) (see Appendix A).”;

(2)  in Article 1.2.1.1., by replacing Clause (b) of Sentence (1) by the following:

“(b) using alternative solutions that will achieve at least the minimum level of performance required by Division B in the areas defined by the objectives and functional statements attributed to the applicable acceptable solutions approved by the Board (see Appendix A).”;

(3)  by adding the following after Article 1.2.2.3.:

“1.2.2.4. Lightning Protection

(1) Every lightning protection system shall comply with CAN/CSA-B72-M, “Installation Code for Lightning Protection Systems.””;

(4)  by replacing Article 1.3.3.1. by the following:

“1.3.3.1. Application of Parts 1, 7, 8, 10 and 11

(1) Parts 1, 7 and 8 of Division B apply to all buildings covered by the NBC. (See Article 1.1.1.1.)

(2) Part 10 of Division B applies to every building under alteration, maintenance or repair that has been built for not less than 5 years, in accordance with section 1.02.

(3) Part 11 of Division B on energy efficiency applies to the construction and addition work of all buildings covered by the NBC (see Article 1.1.1.1. and Appendix A)

(a) having a building area not more than 600 m2,

(b) having a building height of not more than 3 storeys, and

(c) having a Group C major occupancy and housing only dwelling units.”;

(4.1)  by replacing “9” in Sentence (3) of Article 1.4.1.1. by “11””;

(5)  in Sentence (1) of Article 1.4.1.2.,

(a) by replacing the definition of “Authority having jurisdiction“ by “Authority having jurisdiction means the Régie du bâtiment du Québec.”;

(b) by replacing the definition of “Boiler” by “Boiler means an appliance, other than a direct-fired service water heater, for heating a liquid or transforming it into steam.”;

(b.1) by inserting the following in alphabetical order:

“Overall thermal transmittance (U-value) means the rate at which heat is transferred through a building assembly that is subject to a temperature difference. It represents the amount of heat transferred through a unit area in a unit of time induced under steady-state conditions by a unit temperature difference between the environments on its two faces. The U-value reflects the capacity of all elements to transfer heat through the thickness of the assembly, as well as, for instance, through air films on both faces for above-ground components.”;

(c) by striking out the definition of “Constructor”;

(d) by replacing the definition of “Grade” by the following:

“Grade (as applying to the determination of building height) means the lowest of the average levels of finished ground when the levels are measured along each exterior wall of a building within 3 m from the wall, based on surveys that include any differences in level other than those providing access to the entrance door of the building for vehicles or pedestrians. (See First storey.)”;

(d.1) by inserting the following in alphabetical order:

“Thermal bridge means a heat conductive member that results in a reduction of the total thermal resistance of a separation or as part of the building envelope.”;

(e) by striking out the definition of “Owner”;

(f) by inserting the following after the definition of “Repair garage”:

“Residential board and care occupancy means a care or detention occupancy classified as Group B, Division 2 other than a hospital, an infirmary, a rehabilitation centre or a nursing home that lodges persons requiring personal-support services and needing assistance for their evacuation. (See Appendix A.)”;

(f.1) by inserting the following in alphabetical order:

“Effective thermal resistance (RSIE value) means the thermal resistance of a separation calculated as equal to the weighted average of the total thermal resistance RSIT values of each of the separation surfaces having a separate total thermal resistance RSIT value, so as to allow for the effect of thermal bridges.

“Thermal resistance (RSI value) means the inverse of the overall thermal transmittance (see Appendix A).

“Total thermal resistance (RSIT value) means the thermal resistance of a separation equal to the sum of the thermal resistance of all the layers of material or little or unventilated air composing the separation, calculated through the insulated portion of the separation (see Appendix A).”;

(g) by replacing the definition of “Theatre” by the following:

“Theatre means a place of assembly intended for public performances or viewing of plays, operas, cinematographic works or other similar performances or viewing consisting of an auditorium with permanently fixed seats intended solely for a viewing audience.”;
