Preservation Green Lab

About the Preservation Green Lab

Launched in March of 2009, the Seattle-based Preservation Green Lab advances research that explores the value that older buildings bring to their communities, and pioneers policy solutions that make it easier to reuse and green older and historic buildings. The Green Lab seeks to minimize carbon impacts from the built environment through direct emissions reductions from building retrofits and reuse, and to conserve character-rich and human-scale communities that attract people to more sustainable, urban living patterns.

What's New

Projects + Research

  • Building on Baltimore's History: The latest in a research series, this provides recommendations to leverage Baltimore's historic assets to support successful and equitable revitalization across the city.
  • Retrofitting Philadelphia: The Partnership for Building Reuse explores the challenges and opportunities related to building reuse in a city with a large stock of older, smaller buildings.
  • Older, Smaller, Better: This groundbreaking study demonstrates the unique and valuable role that older, smaller buildings play in the development of sustainable cities.
  • America Saves! to Help Energize Main Street Small Businesses: The Green Lab is helping cities and community development organizations restore their social fabric and neighborhoods and revitalize their economy and community well-being through the America Saves! initiative. The program is a national model for delivering energy efficiency to small businesses and buildings, driving cost savings and new investment in existing buildings and is supported by a $2 million grant award from the U.S. Department of Energy.
  • Outcome Based Energy Codes: A new, Outcome-Based Energy Code framework provides regulatory flexibility and enables innovation in greening older buildings.
  • Partnership for Building Reuse: A new report, Learning from Los Angeles, developed by the Preservation Green Lab in partnership with the Urban Land Institute, recommends strategies to make it easier to reuse and retrofit existing buildings in Los Angeles and elsewhere.
  • Realizing the Energy Efficiency Potential of Small Buildings: A new report produced by Preservation Green Lab shows that small commercial buildings represent a massive and largely untapped opportunity for new energy savings.
  • Green Windows: New research offers insight for homeowners weighing the financial and energy trade-offs between replacing or repairing older, less efficient windows.
  • The Environmental Value of Building Reuse: New research explores the environmental value of reusing buildings rather than demolishing them to replace with new construction.
  • District Energy & Eco-Districts: District Energy and Eco-District strategies can make it easier and more affordable to transition older neighborhoods to cleaner sources of energy as well as pursue the three tenets of sustainability (environment, economic, social) as an overall goal.
