In alphabetical order, add the term, "Roof area is the area of the uppermost surface of the building which covers enclosed Gross Floor Area, as measured when projected onto a flat, horizontal surface (i.e. as seen in Roof Plan view). \'Roofs\', or portions of roofs, covering unenclosed areas (e.g. roofs over porches and open covered parking structures) are not included in the areas used to evaluate compliance with Path 5, though they may be applicable to Path 4."

Below equation, add the text and equation:Alternatively, the following equation may be used to calculate compliance:(see image)

In alphabetical order, add the term "An appurtenance is any built-in, nonstructural portion of a roof system, such as skylights, ventilators, mechanical equipment, partitions, and solar energy panels."

Under "System Boundary" bullet, replace "ISO 21930 section A-1 thru A-4, B-1 thru B-7, and C-1 thru C-4" with "EN 15804-2013 sections A-1 thru A-4, B-1 thru B-5, and C-1 thru C-4."

In table, 4th column under "Documentation," revise the language to read: "Floor plans, sections and/or details (as applicable) showing compliance with flexibility strategies."

Replace Example 3. Multifamily with the following:
A 15 unit multifamily project is 24,000 square feet. It includes four two-bedroom units (1,100 square feet each), three three-bedroom units (1,450 square feet each), and eight studios (750 square feet each) earns 1 point. This project's total in-unit conditioned floor area of 14,750 square feet.

In BD+C, add the following text to the end of the section. In EBOM, add a new bullet point:
"Select plants that provide habitat and promote biodiversity. When specifying adapted vegetation, choose cultivars of native vegetation that are not considered invasive plants or noxious weeds, and that grow reliably well in the project’s locality with minimal maintenance, winter protection, pest protection, irrigation, and fertilization."

Revise the bullet points to read:

"- Option 1 is for projects with compliant at-grade (i.e., nonroof) strategies.
- Option 2 is for projects with compliant roofs.
- Option 3 is for projects with compliant roofs and at-grade (i.e., nonroof) systems.
- Option 4 is for projects with only parking under cover."

Add the following language to International Tips under the Further Explanation section:

"Pressure testing standards
Supply water pressure and flow rate pressure testing standards vary throughout the world. For consistency, it is recommended that all projects use the flow rates reported by the manufacturer at 60 psi (415 kPa) for lavatories and kitchen sinks and 80 psi (550 kPa) for showerheads, or obtain the rated flow rates from an independent testing company.

As of October 2014, a new calculator is available for the Minimum Indoor Air Quality Performance prerequisite. This correction includes the new calculator in the guidance for multiple-zone systems.

1. In Step-by-Step Guidance, Mechanically Ventilated Spaces (and Mixed-Mode Spaces When a Mechanical Ventilation is Active), [BD+C page 611, Step 2; ID+C page 311, Step 2; BO+M page 399, Step 4]
Replace the first sentence in last the bullet with the following: "For multiple-zone systems, use the calculator provided by USGBC or ASHRAE’s 62MZCalc Spreadsheet."
