AmberGlen, LLC, Awarded “Carbon Samurai” Trophy

AmberGlen, LLC, one the Pacific Northwest’s premier corporate campuses, was awarded the grand prize in the Carbon4Square challenge by the Building Owners and Managers Association of Oregon. Principal Real Estate Investors, one of the largest institutional real estate managers in the United States, owns AmberGlen.

The award recognizes real estate firms for success in reducing carbon emissions generated through the four W’s – watts, water, waste and wheels. AmberGlen took home the “Carbon Samurai” award for achieving superior accomplishments in managing carbon emissions across all four categories.

“Our goal is to create and implement industry-leading green initiatives for each property we own,” said Monica Christensen, senior asset manager at Principal Real Estate Investors. “AmberGlen is one of our best examples of this initiative. We’re proud to see the work we’ve done to reduce carbon emissions recognized by the Carbon4Square challenge.”

AmberGlen has been owned by Principal Real Estate Investors’ since 2004. The property consists of three Class A office buildings, with an average ENERGY STAR® score of 85. The buildings have achieved a 28 percent reduction in water use in the 12 months following installation of water wise irrigation controllers, a 35 percent reduction in carbon emissions, and enrolled 80 percent of tenants in a recycling program. Additionally, two electric car charging stations are available, goats are used for vegetation maintenance (instead of gasoline-powered lawn equipment), and covered bicycle parking is available for tenants.

Earlier this year, Principal Real Estate Investors was named the second greenest commercial real estate company by Commercial Property Executive. The rankings recognize the ongoing commitment of “time, staff and corporate culture in a way that will help (commercial real estate companies) gain a leadership position in the commercial real estate sector,” according to the publication.
