## 5.2 General Requirements

Some requirements in the nonresidential lighting standards are classified as “mandatory requirements” because they are required regardless of the compliance approach used. All projects must comply with all mandatory requirements.

It is the responsibility of the designer to design the lighting system and specify products that meet these requirements. It is the responsibility of the installer to install the lighting and controls specified on the plans. It is the responsibility of code enforcement officials to verify that the mandatory features and specified devices are included on the plans and installed in the field.

The mandatory measures for nonresidential indoor lighting include:

• Certain functional areas in nonresidential buildings must comply with the low-rise residential lighting Energy Standards (§130.0(b)).

• Manufactured lighting equipment, products, and devices must be appropriately certified (§110.0(b), §110.1, and §110.9(a)).

• Requirements for how luminaires shall be classified (according to technology),and how installed lighting power shall be determined (§130.0).

• Required indoor lighting controls (§130.1).

• Lighting control acceptance testing (§130.4(a)).

• Lighting control Certificates of Installation (§130.4(b)).

Although not related exclusively to lighting, the Energy Standards impose mandatory measures for electrical power distribution systems. See Chapter 8 of this manual for additional information about mandatory measures for electrical power distribution systems.
