C1 PDD – SPARC Appendix (Sustainable Design Approach)
Energy Use
The designer will analyze energy use (electricity, liquid fuel, natural gas) and capital cost for the C1
expansion and provide options for reducing energy use by 5%, 10%, and 20% below Washington State
Energy Code. Examples include but are not limited to dynamic glass, static glass with low solar heat gain
coefficient, shading devices, regenerative elevators, etc. On-site renewable energy generation may be
considered by the designer to offset energy use to meet this goal. The Port’s Century Agenda goal is to
meet all increased energy demand through conservation and/or renewables. Energy use reduction must
meet the Port’s existing design standards.
Materials
The Port is committed to reducing the embodied carbon of building materials. During design, prior to
contractor bid document completion, the design team will provide the Port Environmental staff with
technical specifications for various materials (concrete, steel, and gypsum) proposed for use on the
project. Materials will be selected that meet the structural and safety standards required for this
project, with the lowest appropriate embodied carbon per unit. The design team is responsible for
collaborating with Port Environmental staff to ensure that selected materials are compliant with LEED
requirements and Port Standards.
Water Use Reduction
The designer will analyze water use and associated cost for the C1 expansion and provide options for
reducing water use by 10% and 20% below Uniform Plumbing Code 2015 and Washington State
Amendments. Areas of reduction could include but are not limited to indoor water use, outdoor water
use, process water demand, rainwater capture, etc. Water use reduction must meet the Port’s existing
design standards.
LEED
The most current version of LEED Building Design and Construction (BD+C) Silver Certification (Port
anticipates it will be version 4.1) will be required for the C1 Expansion.
The LEED integrative process credit requires exploratory discovery analysis during the pre-design and
design phases to identify synergistic attainment opportunities across disciplines and systems. The intent
is to support early high-performance analysis with the project. Discovery items required by this credit
include “simple box” energy analysis, preliminary water budget analysis, and associated implementation
strategies with both items.
The C1 project is required to achieve the following LEED points in the following categories:
• 1 point under the Integrative Process
• 2 points under the Building Product Disclosure and Optimization- Environmental Product
Declarations credit
• At least 2 credits under the Construction Waste Management credit.
The following LEED scorecard may be used to guide which credits to explore for this project:
