Green Building Construction

As an Earth Advantage® Certified Builder, Seabold Construction Co., Inc. is at the forefront of Green and
Sustainable construction practices and technologies; utilizing recommended materials and systems on a number
of projects. We have worked closely with the Portland Development Commission (PDC) and the City of Portland
on their Green Building Initiative and incorporate many of their requirements into our projects.

Clara Vista Townhomes

The Clara Vista Townhomes project completed in 2007 was the first residential LEED® project completed in the Western United States, and was awarded the Silver Certification. This project incorporated a number of green features such as:

Green Initiative
  • Pedestrian oriented streets and paths with easy access to public transportation–1-1 parking provided
  • Storm water management through natural drainage swales at both sites with trench drains at sidewalks
  • Low flow plumbing fixtures, controls, and water efficient appliances
  • Rainwater harvesting for site irrigation and/or community garden and tenant use
  • Energy efficient building systems to include: passive heating, hydronic heating systems, fans with timers and delays, day lighting. High windows with higher ceilings, high performance electric lighting and fixtures, and outdoor lighting controls
  • Renewable energy–solar hot water heating systems
  • Use of one or more of the following: long life, recycled and
    recyclable, natural, non-toxic low embodied energy, low emitting and regional building materials
  • Site protection during construction to control erosion and sedimentation, waste reduction, re-use, and recycling programs
  • New construction on an existing urban location with buildings sited to create community space
  • Building program is stacked to create greater open space for landscaping using native and low maintenance vegetation and trees on paths, courtyards, play areas, and a community garden
  • Educating users, maintenance personnel, and owners on operations and maintenance and waste management

The Heritage Building

In 2007 The Heritage Building renovation project was awarded the LEED® Gold Certification. The project incorporated many green features such as:

Green Initiative
  • Complete renovation of a historically significant building into environmentally responsible office spaces
  • Recycled 95% of all building material waste
  • Geothermal heating and cooling systems accomplished via water injection wells
  • Water flushing system including tank and piping which collects rainwater and is a storm water or rain-harvest tank–the water is filtered, but not treated to the extent greywater would require
  • Storm water management through-out the site; filtering ponds and injection drywell
  • Low-flow plumbing fixtures and controls
  • Use of all of the following: recycled natural, non-toxic, low embodied energy, low emitting and regional materials
  • Educating of users and maintenance personnel on operations and management

Esperanza Court

Esperanza Court, completed in 2008, received recognition from the Oregon Economic Development Department for utilizing brown fields — vacant or underused commercial or industrial properties where known or suspected environmental contamination has created barriers to redevelopment. This project’s challenges included:

Green Initiative
  • Old dilapidated buildings, which were demolished and any useful construction materials were reused
  • The site had become an unsightly dumpsite for used appliances, tires, and general trash debris—these items were recycled where applicable and properly disposed
  • Petroleum products were encountered during excavation and were remediated out of the soil, then reclaimed
  • Trees and wood debris were re-moved and recycled if applicable
  • Masonry items were reused where pertinent
