Investing in ESG to develop buildings. And neighborhoods.

  •  We built the nation’s first LEED Core & Shell Gold certified high-rise office building. Nearly two decades ago.
  • Committed to technology, we developed and continue to manage the first building in all of North America officially certified in both WiredScore and SmartScore at the platinum level.
  • We benchmark all JBC-managed properties for electricity consumption through the EPA’s Energy Star program.
  • Our Foundation and its signature Spring Fling event has raised over $20 million for
    Chicago-area charities.

For decades, we’ve incorporated ESG (Environmental, Sustainable, and Governance) principles into our operations because they align with our focus on enduring value.

Investing in these practices adds to costs per square foot, but it returns major dividends over the long run, including how our work enhances the quality of life in local neighborhoods.

Spring Fling: From $50 in a ball cap to more than $13M in donations.

It started as a small gesture among friends. In 1988, John Buck and several founding partners found themselves at a beer garden one sunny spring day. Not wanting to totally waste the afternoon, John suggested they make the outing a charitable function. Everyone put $50 into a baseball cap, then wrote their favorite youth or education program on a slip of paper and put it in a second cap. The moment a waitress pulled the winners, Spring Fling was born.

Today, The John Buck Company’s Spring Fling stands as the premiere charity celebration in the Chicago Real Estate community. Over the past 30 years, Spring Fling raised more than $13 million for Chicago non-profit organizations. What started as six people ponying up a few hundred bucks now draws over 2,600 attendees annually.

A proud leader in LEED and WELL sustainability.

For nearly two decades, JBC has advocated LEED construction practices. In 2005, 111 South Wacker opened as the nation’s first high-rise office building to receive LEED Core & Shell Gold.

More recently, we have adopted WELL Building Standards that assess how we optimize design and operations for human health and well-being.

As a longtime US Green Building Council Member, JBC designs, constructs, and manages buildings that promote energy efficiency. Our buildings are healthy, thriving, and environmentally responsible places to live and work. We benchmark all JBC-managed properties for electricity consumption through the EPA’s Energy Star program, reviewing and updating their profiles each quarter. We also benchmark all JBC-managed properties for electricity consumption through the EPA’s Energy Star program.

Building better communities: The John Buck Company Foundation

Since inception, The John Buck Company Foundation has donated over $20 million to support Chicago-area children and family organizations with strong commitments to education and well-being of our youth.

When communities struggled with the COVID-19 pandemic, our Civic Involvement Committee (CIC) provided meals to local hospital staff and patients, as well as local charitable organizations. We also coordinated meal preparation with a few of our participating Spring Fling restaurants.

We were honored to provide meals to Roseland Community Hospital, Loretto Hospital, St. Bernard Hospital, South Shore Hospital, Norwegian Hospital, ATI Ambulance, By The Hand Club, Hephzibah House, I Grow, and Children’s Home & Aid Freidheim Center.

We want to thank our restaurant and delivery partners Gatto’s, Giordano’s, Francois Frankie, Roots, ATI and Vandenburg Ambulance for working alongside The JBC Foundation to support our effort to help feed Chicago.

Structured for giving back: The Civic Involvement Committee

At The John Buck Company, we take a holistic approach to improving both our internal and external communities. We created a ten-employee Civic Involvement Committee (CIC) to strategically manage our charitable efforts.

The CIC not only manages our Spring Fling, it also provides employees opportunities to give back through Volunteer Days with local schools or park programs, assembling school supplies for back packs, playing Santa for Holiday Gift programs, and supporting other JBC employee programs like Spooky Zoo at the Lincoln Park Zoo.

With extraordinary levels of employee participation in every aspect, The John Buck Company Foundation has become an integral part of our organization.
