Gulf State Park Interpretive Center

The Gulf State Park Interpretive Center is on track to become Alabama’s first Living Building! The Living Building Challenge is the most stringent and rigorous green building certification in the world.

LBC goals are more ambitious than just minimizing harm to the environment. Instead LBC challenges teams to create buildings that have a restorative impact on human and ecological communities. WATERSHED served as the Gulf Coast Sustainability Specialist for the Interpretive Center, working with the design team to help achieve and document the 20 Imperatives of the Living Building Challenge and achieve LEED Platinum, and Fortified Commercial Certification. The design team was led by Architecture Works out of Birmingham AL.

The Gulf State Park Interpretive Center is designed to be energy and carbon positive. A 1,48k kW solar array produces more energy than the building consumes, with battery storage for resilience. We have also taken steps to offset the embodied carbon of the building materials.

WATERSHED performed a Life Cycle Assessment of all of the materials used in construction. This data was used to calculate a carbon offset for our project that will remove 172 Metric Tons of carbon from the atmosphere, via tree planting and renewable energy projects. This is more carbon than was introduced into the atmosphere by the harvest, extraction, manufacture and transport of the building materials. Carbon Positive buildings are a critical tool to fight climate change. As our coastal communities are faced with increasingly frequent storms and sea level rise, the Interpretive Center demonstrates not only resilience to the symptoms of climate change, but the possibility of a cure.

A Restorative Impact

The Interpretive Center has an 11,000 gallon rainwater cistern. The restrooms, sinks, and water play area use only rain water harvested from the roofs on site and filtered for use. After it is used, that water is purified and returned to the ground for infiltration into a fresh water aquifer under the park, thus restoring the native hydrology of the site. There are significant regulatory hurdles for a small, public project to achieve Net Positive water in this way. In order to “go off the grid” with its water, the Interpretive Center had to become certified as a water treatment plant through the Alabama Department of Environmental Management (ADEM).

Every ingredient of every single building material used on the Interpretive Center Construction, from the wood, to the screws, the roof membrane, to the wiring inside the lighting fixtures, has been carefully vetted to identify and eliminate Red List chemicals of concern.

The red list includes the worst in class persistent biological toxins, known to cause harm to humans and ecosystems. Unfortunately, these chemicals are also quite prevalent in common building materials. Extensive research and communication with manufacturers and their supply chains goes into creating a living building. This work, to publicly disclose building material ingredients, and their health impacts,  is helping to transform markets, and eliminate the red list chemicals from use.

The interpretive center shade structures are influenced by the dappled, filtered light of the maritime oak forests deep in the park. Both the building and porch are intended to offer a dramatic, but safe, platform from which to see and hear the intense rains of the gulf in an immersive experience. The pedestrian overpass from the park to the beach was designed to point travelers towards views of the prehistoric dunes within the park, the mature tertiary dunes across the beach highway, and the developing primary and secondary dune systems at the site. The dunes are off limits to most visitors to the gulf coast, because of their fragile nature, but the sand and water play area at ground level allows guests to experience the dunes from a different perspective, and see the system grow before their eyes.

The Interpretive Center is in its first year of operation. It will take a full year of performance in order to prove achievement of all of the Living Building Imperatives, including net positive water, energy, carbon, and materials. At the end of that year, the Interpretive Center will become officially recognized as a “Living Building.” This tiny building on the gulf coast of Alabama will then join a handful of  global leaders that are moving beyond the paradigm of “sustainability” and demonstrating the possibility of truly restorative development.
