"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."
这栋大楼位于佐治亚理工学院，是美国东南部如此体量的建筑中，首个获得生态认证的建筑。它同时满足“生态建筑挑战”（Living Building Challenge）的七要素：地点、水、能源、健康与幸福、物质、平等、美观。尽管该地区气候温暖潮湿，建筑会面临很多挑战，但该项目在其性能检测阶段，屋顶太阳能板可以为整个电力系统提供225%的能源需求，其收集、处理、渗入水的量也是建筑所需水量的15倍。
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.
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.
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.
● 建筑材料均通过“红色名录”（Red List）评估，筛除有害化学品。这些化学品在建筑材料中很常见，如双酚基丙烷、卤代阻燃剂、邻苯二甲酸盐、甲醛，但现已被证明是对人类健康和环境有害的物质。
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.
● 设计和施工团队在满足“生态建筑挑战”中“平等”的条件以外，还促进了更公平和包容的社区氛围。例如，为了建造天花板和地板系统，总承包商与Georgia Works! 合作，这是一个帮助长期无家可归的人自给自足的非营利组织。
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.
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.
The Kendeda Building is Georgia Tech's first timber building since its earliest load bearing masonry and timber structures from the 1880s. Mass timber was selected for its significantly smaller embodied carbon footprint, compared to concrete and steel systems. Glue laminated queen post trusses with steel bottom chords are used to achieve the spans required by the larger spaces in the building where timber alone would be challenging. This hybrid approach reduces the quantity of wood required, while making routing of building services more efficient. The gravity and lateral elements are fully exposed, allowing the building to be a teaching tool and defining the character of the interior environment.
At $544 per gross square foot, the Kendeda Building is 13 percent more expensive than a comparable building at Georgia Tech. However, in reality, there are few comparable buildings of this type that include the infrastructure for net positive energy and water in the construction cost. The Kendeda Building serves as an inspiration and gathering place for people from around the region who are advancing sustainability and regenerative design.
