In my opinion, HOK’s design of the National Wildlife Federation HQ Green Façade is one of the loveliest examples of integrating living architecture on a building and expressing biophilia to the workplace.

That’s why I included this beautiful and sensitively designed project in my 2018 Top 10 List of Hot Trends in Greenroof & Greenwall Design in the #4 category of Living Architecture Ecosystem Services: Blending Biophilia Seamlessly with the User Experience.

And so it necessitated being highlighted as a Featured Project, too! Thank you to greenscreen®, in particular Reuben Freed who supplied most of the background and photos, and who also expressed his deep respect for the HOK designers of the NWF green façade.

He says this project is the first green façade to demonstrate the passive benefits of biomimicry in action using a ‘structured landscape intervention.’

NWF began its design process for the new headquarters with William McDonough + Partners with an in depth goal-setting session, which then guided the site selection and the selection of the architect, HOK.

Reuben wanted to ensure we credited these former HOK architects for their thought leadership in the field:  Debra Gunther and Sandra Mendler (now with Mithun) and Mary Ann Lazarus, FAIA (now with Cameron MacAllister Group). Kudos to all for a great job!

Excerpt from the Project Profile:

Since 1936, the National Wildlife Federation or NWF has worked across the US to unite Americans from all walks of life in giving wildlife a voice as America’s oldest and largest conservation organization. Built in 2000, the 95,000 square foot LEED certified NWF Headquarters in Reston, Virginia overlooks a wildlife sanctuary.

Architect HOK took a common sense and common ground approach to conservation, minimizing habitat loss, and securing places for wildlife. The design team’s integrated LID strategy included a green façade with native plants for habitat restoration; bio-retention ponds for site water management; and vegetation for air quality improvement.

The landscape is a tapestry of native plant materials that extend to the vertical plane through a freestanding 40’ high greenscreen® green façade. Integrated with the south glazed elevation, the green façade provides passive solar control.

Energy modeling shows the deciduous sunscreen is more effective at improving energy performance than more expensive design options relying on fixed architectural sunscreens. A drip irrigation system uses water from the site’s retention ponds, and the green façade has a Biodiversity Zone behind and below its structure.

Native vines on the green façade offer great wildlife value and include Trumpet Honeysuckle, Trumpet Creeper, and Crossvine to name a few.

Over the years the network of twining stems populating the screen has created a habitat for birds, insects and even raccoons and snakes, allowing intimate views of life in the trellis from inside.

This added benefit is a constant delight to office workers and school groups that tour the building. The NWF’s commitment to natural infrastructure protects wildlife and enhances living architecture ecosystem services for flora, fauna, and people.

The wide windows of its Headquarters allow daily glimpses of wildlife from within the office only 40 inches away, creating a “Biophilia @ Work” atmosphere for NWF employees.
