Sustainable Design & Certification

• Target certification: LEED Platinum (Core & Shell) and WELL Building Standard.
• key strategies:

1. Net‑zero energy envelope – high‑performance glazing, triple‑pane insulated glass, and on‑site solar PV generating ≈ 600 kW.
2. Water stewardship – rainwater harvesting for irrigation and gray‑water reuse for toilets (≈ 70 % reduction in potable water use).
3. Materials openness – embodied‑carbon tracking through the Embodied Carbon registry (ECR) to stay below 150 kg CO₂e/m².
4. Transit‑oriented placement – direct connection to the Portland Streetcar and MAX Light Rail, encouraging 80 % of occupants to use public transit.

Economic Impact

• Job creation: Approx. 1,200 construction jobs (2026‑2028) and 800 permanent jobs across office, hospitality, and retail sectors.
• Tax revenue: Estimated $12 M in annual property tax and $4.5 M in sales tax from retail and hotel operations.
• Housing affordability: 20 % of residential units designated as “affordable‑by‑design,” with rents capped at 60 % of median Portland income.

urban Revitalization Benefits

1. Activation of the South Waterfront corridor – The tower’s public podium bridges the riverfront park and the existing mixed‑use district, creating a continuous pedestrian experience.
2. Catalyst for further investment – Comparable projects (e.g., the 450‑ft “Riverplace Tower” completed 2022) spurred $1.3 B in adjacent development within three years.
3. Cultural integration – The on‑site art gallery partners with Portland Art Museum, rotating exhibitions that showcase Pacific Northwest artists.

Practical Tips for Stakeholders

• Investors: Leverage the building’s ESG credentials to attract green‑finance instruments such as sustainability‑linked bonds (target yield - 2.3 %).
• Tenants: Take advantage of the building’s smart‑metering portal to monitor energy usage and qualify for corporate carbon‑offset programs.
• Residents: Participate in the “Community Green Roof” program, where occupants can reserve garden plots for urban farming.

Comparative Case Study: “The SODO Tower” (2021‑2024)

• Height: 380 ft, mixed‑use (150 units, 100,000 sq ft office).
