scope:

This code applies to commercial buildings and the buildings sites and associated systems and equipment.

The code applies to residential and commercial buildings and the buildings' site and associated systems and equipment. The definitions for "Residential building," "Commercial buildings," and "Building site" will be important in correctly applying the provisions of the code. See the commentary related to the definitions in Chapter 2[CE]. Additional discussion also will be also found in Chapter 4[CE] commentary.

Purpose

Though not stated specifically, the code is applicable to all buildings and structures, and their components and systems that use energy primarily for human comfort. The code does not regulate the energy for industrial equipment for manufacturing or that is needed for items such as computers or coffee pots. The code, therefore, addresses the design of energy-efficient building envelopes, and the selection and installation of energy-efficient mechanical, service water-heating, electrical distribution and illumination systems and equipment in residential and commercial buildings alike.
