Georgia Tech's Kendeda building goes one step further as a living building design. In order to attain the coveted status of a living building, a structure must adhere to a stringent set of criteria encompassing seven key performance areas, termed "petals": Place, Water, Energy, Health & Happiness, Materials, Equity, and Beauty. These petals encompass a wide array of sustainable design considerations, including site selection, water conservation, energy efficiency, indoor air quality, material sourcing, and social justice.

The Kendeda Building exemplifies this commitment by:

  • Generating surplus energy from renewable sources like solar panels.

  • Managing all water needs through on-site harvesting and treatment methods, including rainwater collection and greywater recycling.

  • Selecting materials that promote healthy indoor environments and occupant well-being by being free from toxins.

  • Incorporating biophilic design elements to foster a deeper connection with nature and enhance the overall user experience.

  • Demonstrating a dedication to social equity by ensuring accessibility, diversity, and inclusivity in both its design and operation.

There are very few living buildings in the world but each one exemplifies the dynamics involved in creating a environmentally harmonious livable habitat.

Biophilic Design

Biophilic design explores the connection between humans and nature within built environments. This concept emphasizes integrating natural elements into architectural structures, fostering improved well-being and a harmonious relationship with the surrounding environment.

One example of biophilic design is the Bosco Verticale (Vertical Forest) in Milan, Italy. Designed by architect Stefano Boeri, this innovative residential complex consists of two high-rise towers covered with over 900 trees, 5,000 shrubs, and 11,000 perennial plants. The lush vegetation not only creates a striking visual impact but also serves several functional purposes, including air purification, noise reduction, and temperature regulation. The Bosco Verticale provides residents with access to nature within an urban setting, promoting well-being and biodiversity while mitigating the environmental impact of the buildings. This project demonstrates how biophilic design principles can be integrated into dense urban environments to create sustainable and livable spaces that prioritize the human-nature connection.

Circular Economy in Construction

Circular economy in construction refers to a holistic approach to resource management within the construction industry, aimed at minimizing waste, maximizing resource efficiency, and promoting sustainability throughout the building lifecycle. Instead of the traditional linear "take-make-dispose" model, which leads to significant resource depletion and environmental degradation, the circular economy model focuses on creating a closed-loop system where materials and resources are reused, recycled, or repurposed to extend their lifespan and minimize waste generation.

Key principles of circular economy in construction include:

  1. Designing for Deconstruction: Buildings are designed with the end in mind, making it easier to disassemble and recover materials for reuse or recycling at the end of their life.

  2. Reuse and Repurposing: Salvaging materials from demolished or renovated buildings for reuse in new construction projects, thereby reducing the demand for new resources and minimizing waste.

  3. Recycling and Upcycling: Recycling materials such as concrete, steel, and glass to create new building components or products, diverting waste from landfills and conserving raw materials.

  4. Resource Optimization: Maximizing resource efficiency through measures such as efficient material usage, energy-efficient design, and renewable energy integration to minimize resource consumption and environmental impact.

  5. Extended Producer Responsibility: Encouraging manufacturers and stakeholders to take responsibility for the entire lifecycle of their products, including end-of-life disposal or recycling, promoting the adoption of sustainable and circular practices.

  6. Collaborative Partnerships: Fostering collaboration among stakeholders across the construction value chain, including designers, architects, contractors, manufacturers, and policymakers, to drive innovation and adoption of circular economy principles.

By embracing circular economy principles, the construction industry can transition towards a more sustainable and regenerative model, where materials and resources are continuously circulated within the economy, reducing waste, conserving resources, and mitigating environmental impact.
