Strike Section 603.1 of the International Green Construction Code in its entirety and insert new Section 603.1 in the Green Construction Code in its place to read as follows:

603.1 Scope. The provisions of Section 603 shall only apply to new construction and projects that are undertaking a complete electrical system replacement. Section 603 shall not apply to Group R occupancies.

603.1.1 Purpose. The purpose of this section is to provide requirements that will ensure that buildings are constructed or altered in a way that will provide the capability for their energy use, production and reclamation to be measured, monitored and reported. This includes the design of energy distribution systems so as to isolate load types, the installation of or ability to install in the future meters, devices and a data acquisition system, and the installation of, or the ability to provide, energy displays and other appropriate reporting mechanisms in the future.

All forms of energy delivered to the building and building site, produced on the building site or in the building, and reclaimed at the building site or in the building shall be metered and all energy load types measured in accordance with this section.

603.1.1.1 Buildings with tenants within the scope of Section

1. In buildings with nonresidential tenants, the metering required by Section 603.3 shall be collected for the entire building and for each floor in the building. Tenants within the scope of Section 603 shall have access to all data collected for the floors in which they have occupancy. Means of access shall be left to the discretion of the owner.

Strike Section 603.3.7 of the International Green Construction Code in its entirety and insert new Section 603.3.7 in the Green Construction Code in its place as follows:

603.3.7 Renewable energy. Equipment and systems providing energy from renewable energy sources which is included in the determination of the building zEPI, shall be capable of being metered to allow a determination of the output of equipment and systems in accordance with Sections 603.3.7.1 through 603.3.7.3.

603.3.7.1 Solar electric. Equipment and systems providing electric power through conversion of solar energy directly to electric power shall be capable of being metered so that the peak electric power (kW) provided to the building and its systems or to

off-site entities can be determined at 15 minute intervals, and the amount of electric power (kWh) provided to the building and its systems can be determined at intervals of one hour or less.

603.3.7.2 Wind power systems. Equipment and systems providing electric power through conversion of wind energy directly to electric power shall be capable of being metered so that the peak electric power (kW) provided to the building and its systems or to off-site entities can be determined at 15 minute intervals, and the amount of electric power (kWh) provided to the building and its systems can be determined at intervals of one hour or less.

603.3.7.3 Other renewable energy electric production systems. Equipment and systems providing electric power through conversion of other forms of renewable energy directly to electric power shall be capable of being metered so that the peak electric power (kW) provided to the building and its systems or to off-site entities can be determined at 15 minute intervals, and the amount of electric power (kWh) provided to the building and its systems can be determined at intervals of one hour or less.

Strike Section 603.4 of the International Green Construction Code in its entirety and insert new Section 603.4 in the Green Construction Code in its place to read as follows

603.4 Energy load type sub-metering. For buildings that are not less than 50,000 square feet (4645 m²) in total building floor area, the energy use of the categories specified in Table 603.2 shall be metered through the use of sub-meters or other approved equivalent methods meeting the capability requirements of Section 603.3.

603.4.1 Buildings less than 50,000 square feet. For buildings that are less than 50,000 square feet (4645 m²) in total building floor area, the energy distribution system shall be designed and constructed to accommodate the future installation of sub-meters and other approved devices in accordance with Section 603.4. This includes, but is not limited to, providing access to distribution lines and ensuring adequate space for the installation of sub-meters and other approved devices.

Strike Section 603.5 of the International Green Construction Code in its entirety and insert new Section 603.5 in the Green Construction Code in its place to read as follows:

603.5 Minimum energy measurement and verification. Meters, sub-meters, and other approved devices installed in compliance with Sections 603.3 and 603.4

shall be connected to a data acquisition and management system capable of storing not less than 36 months' worth of data collected by all meters and other approved devices.

Strike Section 603.6 of the International Green Construction Code in its entirety without substitution.

Strike Section 602.2 of the International Green Construction Code in its entirety (including associated subsections) without substitution.
