佐治亚理工学院宣布Kendeda大楼创新可持续设计荣获生命力建筑挑战（Living Building Challenge，以下简称LBC）认证，该挑战是世界上最具雄心和整体性的绿色建筑成就。国际未来生活研究所的认证表明Kendeda大楼是世界上最环保的建筑之一。
The Georgia Institute of Technology today announced that the Kendeda Building for Innovative Sustainable Design has earned Living Building Challenge certification, the world’s most ambitious and holistic green building achievement. The certification from the International Living Future Institute independently verifies that the Kendeda Building is among the greenest in the world.

“We feel a responsibility to lead by example,” said Ángel Cabrera, president of the Georgia Institute of Technology, where the Kendeda Building is located. “This building — which is a tribute to the power of human ingenuity to find new solutions to our greatest challenges — aligns with our long-standing vision for our campus to serve as a laboratory for innovation to inspire and develop tomorrow’s leaders who advance technology and improve the human condition.”

The Living Building Challenge (version 3.1) requires a 12-month performance period, during which time the project must prove it is net-positive for energy and water. This means it generates more energy from onsite renewable sources than it uses. The building also collects and treats more rainwater onsite than it uses for all purposes, including for drinking. Meeting all seven Petals in the Living Building Challenge — Place, Water, Energy, Health + Happiness, Materials, Equity, and Beauty — the Kendeda Building is the first Living Certified building of its scale in the Southeast U.S., where a warm humid climate poses many challenges. In spite of this, over the performance period the building generated 225 percent of the energy needed to power all of its electrical systems from solar panels on its roof. It also collected, treated, and infiltrated 15 times the amount of water needed for building functions.

“We partnered with Georgia Tech on this transformational project because the institution is full of world-class problem solvers. Students passing through the Kendeda Building today will be the engineers, architects, scientists, product designers, urban planners, and policy makers of tomorrow,” said Diana Blank, the founder of The Kendeda Fund, whose $30 million grant to Georgia Tech made the building possible. “By raising the bar for building performance, we are encouraging Georgia Tech to keep reaching higher.”

The project’s goal is to support the educational mission of Georgia Tech while transforming the architecture, engineering and construction industry in the Southeast U.S. by advancing regenerative building and innovation, and by showcasing synergies between environmental stewardship, social equity, and economic development. Regenerative buildings create more resources than they use, including energy and water. Through the act of creating buildings that are regenerative, Georgia Tech is charting a path for others to reverse climate change, support human health and address social inequalities.

LBC包括七个名为“花瓣”的性能类别，这些类别又细分为20项条令，项目必须满足这些条件才能获得认证。Kendeda大楼的性能指标包括： •高效节能的机电设备，紧凑的建筑外形，每年可提供225%建筑所需能源的330千瓦光伏顶棚。 •光伏顶棚为建筑遮阳并收集雨水。水储存在5万加仑的水箱中，经处理后用于各种用途，包括饮用。 •该楼由不含“红色清单”上有害化学品的材料组成，例如双酚A（BPA）、卤化阻燃剂、邻苯二甲酸盐和甲醛等，虽然这些化学品常见于大多数建筑，但它们已被证明会危害人类及环境健康。 •来自可持续森林的木材、回收材料及其他材料来源显著地减少了建筑的隐含碳排放。 •该项目通过消除99%的建筑垃圾，以及采用从当地回收的材料，例如用于结构平台的再生木材和厕所中的回收石板瓦等，使回收垃圾多余产出垃圾。 •堆肥厕所几乎消除了将饮用水用于冲马桶的情况，还使排泄物转化为肥料供外部使用。 •该楼允许所有人进出，其主要亮点在于连接一层空间的无障碍坡道，它使所有人都具有相似的空间体验。 •设计团队与施工团队通过促进公平、包容的社区意识，超越了LBC的公平指标。例如，该项目的天花和地面由总承包商与帮助流浪者自力更生的非营利组织Georgia Works!合作完成。

The Living Building Challenges consists of seven performance categories called Petals that are subdivided into 20 Imperatives, which must be met to earn the certification. Performance metrics from the Kendeda Building include the following: •Energy efficient electrical and mechanical equipment, a tight building envelope, with a 330-kilowatt photovoltaic canopy that supplies 225 percent of the building’s energy needs on an annual basis. •The photovoltaic canopy shades the building and captures rainwater. The water is stored in a 50,000-gallon cistern in the basement, before being treated and used for all purposes, including drinking. •The building is composed of materials screened for hazardous “Red List” chemicals, such as bisphenol A (BPA), halogenated flame retardants, phthalates, and formaldehyde. Chemicals on the Red List have been shown to harm human and environmental health, even though they are common in most buildings. •Wood from sustainably managed forests, salvaged materials and other sourcing strategies significantly reduce the building’s embodied carbon emissions. •By eliminating 99 percent of its construction waste and incorporating reclaimed locally sourced materials, such as reclaimed wood for the structural decking and salvaged slate tile in the restrooms, the project diverted more waste from the landfill than it sent to the landfill. •Composting toilets nearly eliminate potable water use for sewage conveyance and allow for human waste to be turned into fertilizer for use off-site. •The building allows for universal access. Its central feature is an accessible ramp connecting the terraced main floor so that all people have a similar experience throughout the project. •The design and construction team went above and beyond the Living Building Challenge Equity Petal by promoting an equitable and inclusive sense of community. To build the ceiling panels and floor systems, for example, the general contractor partnered with Georgia Works!, a nonprofit helping chronically homeless men become self-sufficient.

“Living Buildings are the future,” said Scott Cannon, executive vice president and general manager of Skanska’s building operations in Georgia and South Carolina, the general contractor. “We’ve been committed to sustainability for years and have seen how projects like this are a catalyst to reshape how people think about the built environment. It illustrates the practical and replicable solutions, materials, and technologies that other buildings in the Southeast can use to meet similar environmental standards.”

Regenerative design is resilient and supports carbon neutrality, helping to fight climate change. In a region challenged by flooding and drought, the Kendeda Building also shows that regenerative design can treat stormwater, conserve potable water, lower the risk of downstream flooding, reduce burden on existing infrastructure, and save money on utilities.

Lord Aeck Sargent事务所的Joshua Gassman是该项目的首席建筑师之一，他表示：“毫无疑问，我们已经证明在亚特兰大和整个东南部地区，建筑可以实现净能源效益。我们通过详细分析和完善的建筑科学，为大楼的使用者提供舒适环境，将他们与自然联系起来并且享用基地内的水电设施。我们已经做到了这一切，并且为未来创造出清晰、可持续的愿景。”
“If there was any doubt, we have shown that net positive energy and net positive water are both within reach in Atlanta and across the Southeast,” said Joshua Gassman of Lord Aeck Sargent, one of the lead architects on the project. “Using analytics and sound building science, we were able to provide comfort to the building’s occupants, connect them to nature and the history of the place, and live within the water and energy means of the site. We were able to do all of this while creating a clear and sustainable vision for the future.”

Miller Hull Partnership事务所与Lord Aeck Sargent事务所合作完成该项目并且是另一栋LBC认证建筑Bullitt中心的首席设计团队，其负责人Margaret Sprug说：“我们从Bullitt中心吸取了经验，并将这些理念应用于新气候和新建筑类型。Kendeda大楼是该地区可持续和再生设计推动者的灵感源泉和聚集地。”
“We took the lessons we learned from the Bullitt Center and adapted those ideas for a new climate and new building type,” says Margaret Sprug, principal at The Miller Hull Partnership, which designed the building in collaboration with Lord Aeck Sargent and served as the lead architect of the Bullitt Center, another well-known Living Building. “The Kendeda Building serves as an inspiration and gathering place for people from around the region who are advancing sustainability and regenerative design.”

The knowledge and processes of the Kendeda Building are already being translated to other projects. Thousands of people have toured the project, the entire design and construction team have learned deep sustainability lessons throughout the life of the project, and the students and administrators who inhabit the building on a daily basis will all take these lessons out into the world and apply them to their future projects.
