FOREWORD

Addendum a reflects SSPC 189.3 efforts to identify the revisions necessary to align the standard with the 2018 IgCC powered by ASHRAE Standard 189.1-2017, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings.

Significant changes include the following:

• In Section 6, "Water Use Efficiency," the provisions of this entire section become mandatory, and a requirement for water-bottle filling stations has been added. An exception related to Standard 189.1, Section 6.3.8, "Dual Water Supply Plumbing," has been provided.

• In Section 7, "Energy Efficiency," the exception to Section 7.3.4, "Peak Load Reduction" has been carried over and coordinated with this provision, becoming mandatory. Section 7.4.1.1, "On-Site Renewable Energy Systems," has been removed; users should refer to Standard 189.1 for compliance. In coordination with the integration of regulated and unregulated electric load components, in Section 7.5.1, "Annual Energy Cost," the annual energy cost performance option applies the equation from Standard 189.1; however, Sections 7.5.1 "Annual Energy Cost," and 7.5.2, "Annual Carbon Dioxide Equivalent (CO₂e)," shall apply building performance factors as provided in the revised Table 7.5.2A, "Energy Cost and CO₂e Building Performance Factors (BPF)."

• In Section 8, "Indoor Environmental Quality (IEQ)," an informative note has been added to assist the user in properly applying the reference FGI information related to Section 8.3.3, "Acoustical Control."

• In Section 10, an exception related to the Indoor Environmental Quality Survey is provided.

• Section 12, "Normative References," has been revised to include ASHRAE Standard 90.1-2016 and Standard 189.1-2017, along with the 2018 versions of the FGI guidelines.

Note: In this addendum, changes to the current standard are indicated in the text by underlining (for additions) and (for deletions) unless the instructions specifically mention some other means of indicating the changes.
