Stringham Construction: TOD Apartments

This project by Stringham Construction is piloting the wave of new multifamily checklist projects. Located near Capitol Hill’s light rail station, the TOD (Transit Oriented Development) Apartments feature 49 units with a Walk Score of 96, an abundance of bike storage, top-of-the-line finishes, vibrant colors, and a focus on energy efficiency.

The whole-building VRF heating and cooling systems, solar panel array, high-efficiency centralized gas water heaters, Energy Star appliances, LED lighting, and tested low-flow plumbing fixtures give this apartment building an edge, with energy savings of over 45 percent better than state energy code.

Vital Stats



Location: Capitol Hill (Seattle)
Star Level: 4-Star 
Checklist: Multifamily residential new construction (2017)
Verifier: Evergreen Certified
Site and Water 152
Energy Efficiency 99
Health and Indoor Air Quality 121
Material Efficiency 69
  Total Score 457


In conjunction with energy efficiency, indoor air quality (IAQ) was also a large forethought, with the purchase of recycled content CRI Green Label carpet tiles for the hallways, FloorScore certified flooring for the units, zero VOC paints throughout, and CARB-compliant wood composite products. And to prevent future moisture and mold issues, BEE Engineering was hired to consult on the project, including providing specs for the installation of the rainscreen beneath the siding, the siding, liquid flashing, and windows.

Besides energy and IAQ, the units come partially furnished and equipped with dimmable light switches, humidistat and bathroom timer switches, programmable thermostats to control the mini-splits, washer, dryer, refrigerators, dishwashers, and microwave (all Energy Star). Each unit is sub-metered for electrical and water, so the residents get to know exactly what they consume. Besides that, the building is fully accessible, with multiple decks for entertaining!
