In September 2015, the Georgia Tech Institute of Technology received a $30 million commitment from The Kendeda Fund to building what the partners expected to become the most environmentally advanced classroom and teaching lab building ever constructed in the Southeast. The partners had two shared goals:
- demonstrate that a regenerative building can be built in a hot and humid climate, and
- inspire change on the Georgia Tech campus and across the Southeast building industry.
The Kendeda Building for Innovative Sustainable Design is the result of this bold vision. We accomplished the first goal in March 2021 when The Kendeda Building received Living Building Challenge (LBC) certification, the world’s most ambitious and holistic green building achievement. The Kendeda Building is the first Living Building in Georgia and the 28th in the world!
The Living Building Challenge is a rigorous, performance-based standard that aligns with Georgia Tech’s longstanding vision for the campus. Fully certified projects must meet all of the objectives contained in seven performance areas or “Petals” that are divided into 20 requirements called “Imperatives.” Moreover, the project must prove that it is net-positive water and energy over a minimum of 12 months of continuous occupancy and operations. The Kendeda Building provides a unique opportunity to physically demonstrate how Georgia Tech practices thoughtful stewardship of all of its resources and how its innovative thinking can transform future generations.

Site and Building Size:
- Site is 58,800 square feet (1.35 acres). Building's footprint on the site is 18,600 sq. ft. (first floor gross sq. ft. of enclosed space only).
- Approximately 47,000 sq. ft. of programmable space of which nearly 37,000 sq. ft. is enclosed and conditioned space.
- Public outdoor learning space includes the 3,600 sq. ft. outdoor porch area and a 1,000 sq. ft. accessible roof deck. The 4,300 sq. ft. rooftop garden, while not open to the public, contains the honeybee apiary, pollinator garden, and blueberry orchard. The remaining space is for loading and bike storage.
Primary Use of the Building: Non-departmental education, research, and outreach opportunities. The "non-departmental" is extremely important because Georgia Tech wants the full breadth of its undergraduate students to have at least one class in the building so each of them can be inspired to help create a regenerative future.
The building features two 64-person classrooms, two 24-person class labs, two 16-person class labs, a 16-person seminar room, a 24-person design studio, 176-person auditorium, rooftop apiary and pollinator garden, and an office space for co-located programs. The building also hosts the building Director and staff, the Office of Campus Sustainability, and Georgia Tech's Global Change Program.
Cost per Square Foot: At approximately $544 per gross square foot, The Kendeda Building is about 13% more expensive than a comparable Georgia Tech building. However, in reality, there are few comparable buildings of this style that include the infrastructure for net positive energy and water in upfront construction cost. In other words, unlike conventional buildings that treat utility costs as operating expenses, The Kendeda Building pre-purchased 30 years of electricity, has the ability to convert rainwater to drinking water, and treats sewage onsite.
Net Positive Water (12-Month Performance Period):
- Basement Cistern Capacity: 50,000-gallons of rainwater
- Toilets and Urinals: 12 foam flush toilets and 4 waterless urinals use less water than one typical low-flow toilet
- Water Used: 104,600 gallons
- Water Collected and Infiltrated into the Ground: 1,594,800 gallons, which is 15 times the amount needed for operations
- NOTE: when the rainwater-to-drinking water system receives all required permits, the building will only use rainwater for all potable water needs
Net Positive Energy (12-Month Performance Period):
- Solar Array: 330 kW (DC), approximately 917 SunPower solar panels generated 438,709 kWh.
- Actual Energy Use Intensity (EUI): 18 kBTU/SF/YR before factoring onsite solar, which makes the building 60% to 80% more efficient than a comparable new, conventionally built higher education building in Atlanta.
- Renewable Energy: Photovoltaic system supplied 225% of building’s energy needs, far exceeding the 105% LBC requirement
- Electricity Used: - 243,520 kWh
- Approximate Cost for Electricity: - $15,500 (this is a conservative figure)
- NOTE: while the building has a small battery for emergency back-up, the building pulls from the electricity grid when needed and sends excess during periods of overproduction
Zero Carbon Construction: Project construction achieved zero carbon footprint by first incorporating low-carbon and salvaged building materials, then by recycling over 99% of construction waste, and finally by purchasing a one-time carbon offset that funded new solar projects in India, which is highly reliant on coal for electricity.
- The Kendeda Building site, which was formerly a parking lot, acts like a forest with 90% of an average rainfall managed onsite.
- A composting toilet system converts solids and liquids into fertilizer onsite. The system does not connect to the sewer.
- Greywater, i.e., water that does not contain organic matter, is collected from shower drains, sink drains, and water fountains and pumped to a constructed wetland at the main entrance of the building. There, natural processes involving vegetation, soils, and their associated microbes improve water quality. Instead of going down the drain and into the sewer, the treated greywater infiltrates back into the soil to recharge the surrounding groundwater.
- Project kept economic benefits close to home by sourcing at least 50% of products and services from within 621 miles (i.e., 1,000 km).
- Construction of the building diverted more waste from the landfill than sent to the landfill through the use of salvaged materials.
- Project preserved Georgia Tech’s heritage by converting original heart pine joists used in the construction of the iconic Tech Tower into treads for the Kendeda Building’s monumental staircase. Use of salvaged wood from Tech Tower saved $60,000 as compared to using new materials.
- Lumber from storm-felled trees on Georgia Tech’s campus was kiln-dried, milled, and planed to make the building’s counters and benches outside the building.
- Portion of the floor deck incorporated 25,000 linear feet of dismantled movie sets, and was constructed by participants of a workforce development program for economically disadvantaged Atlanta residents.
- The building is composed of materials screened for hazardous chemicals known to harm human and environmental health, even though they are common in most buildings.
- Every regularly occupied space has access to daylight.
It Takes a Village to Raise a Living Building: This building was, and continues to be a labor of love. Hundreds of people were involved with turning a vision into reality. Visit our photo album to see team members throughout the journey.
