6 Design trends driving a sustainable, regenerative future

The AIA Committee on the Environment (COTE®) originated the AIA Framework for Design Excellence to equip and encourage architects to embrace sustainable design practices. Now widely adopted across the profession, the framework is an industry-wide guide for performance and innovation in architecture.

Annually, the AIA COTE® Top Ten awards celebrate the projects that best put the Framework for Design Excellence into action. This Earth Month, we’re looking back at the last three years of winning projects to understand how architects and their clients are helping communities and healing the environment.

Recent winners demonstrate one major commonality: the most consequential, holistic sustainable design work in the United States is being led by mission-driven organizations. Universities, nonprofits, public agencies, conservation groups, and affordable housing developers are commissioning buildings that exemplify all 10 measures of design excellence. Building owners who anchor capital projects in values like equity, stewardship, and long-term benefit are giving architects the latitude to pursue grounded yet innovative design solutions.

The following design trends, exemplified by COTE® Top Ten projects from 2023, 2024, and 2025, reflect how mission-driven clients and the architects who partner with them are setting precedents. That’s critical in a moment when the stakes of climate action feel urgent and overwhelming.

1. Community is at the center of climate action

Community-centered design strengthens both environmental performance and the social systems that support long‑term resilience. When buildings integrate services, gathering spaces, and everyday amenities, they reduce transportation demand, improve public health, and create the conditions for lower‑carbon living. By prioritizing access, walkability, and shared resources, community-centric developments show how investments in well‑being can directly advance holistic sustainability goals, foster locals to be climate action advocates, and reinforce neighborhood stability in the face of a changing climate.

COTE® Top Ten projects consistently demonstrate how buildings that intentionally serve community connectivity enhance resilience by pairing essential services and cultural spaces with high‑performance systems and generous access to nature and amenities. Ranging from affordable housing and education campuses to civic institutions, award-winning projects show how integrating housing with mobility networks, clustering programs around shared courtyards and public spaces, and including elements of environmental education in design can strengthen social cohesion while reducing carbon impacts. 

2. Architecture is moving toward regeneration

Regenerative design is shifting the focus of sustainable practice from minimizing harm to actively repairing ecological systems. Architects and collaborators are leveraging projects to restore habitat, rebuild soil health, manage water, and strengthen biodiversity, reframing the built environment as a participant in ecological processes rather than an interruption to them. As more institutions and firms adopt this mindset and supporting strategies, regeneration is becoming a defining measure of building performance, one that expands the role of architecture in addressing climate and ecosystem health.

With regenerative strategies, COTE® Top Ten winners have transformed buildings and landscapes into active ecological contributors. Spanning parks, campuses, cultural institutions, and research environments, projects integrate habitat restoration, carbon‑sequestering landscape design, and biodiversity‑supporting plant communities. Many reconnect fragmented ecosystems and create microclimates that cool surrounding neighborhoods. Others demonstrate how institutional campuses can manage water at large scales; support returning species of plants, insects, and animals; and embed ecological learning into everyday experience. 

3. Analysis is a powerful net zero engine

Performance modeling, occupancy evaluation, and interdisciplinary research are increasingly shaping design projects. Rather than relying on assumptions or aspirational targets, firms are grounding decisions in measurable data and iterative testing. This shift reflects the broader cultural move toward evidence-based practice, supported by clients who are willing to invest in deeper inquiry.

Recent winners of the COTE® Top Ten consistently show how robust analysis and evaluation can chart clear pathways to net zero. Design teams are using early‑stage energy modeling, daylight and comfort simulations, carbon accounting, and scenario testing to refine massing, envelope strategies, and mechanical systems long before construction begins. Many projects pair these analysis methods with post‑occupancy evaluation and research partnerships that feed performance data back into design with the intention of improving future outcomes, including net zero and net positive buildings. 

4. The case for adaptive reuse persists

As embodied carbon becomes a central metric of climate action, adaptive reuse remains one of the most powerful strategies available to architects and building owners. Renovation preserves material value, reduces demolition waste, and extends the life of existing structures. Underscoring a broader recognition that climate stewardship begins with what already exists, mission-driven organizations are demonstrating how reinvesting in existing buildings can advance carbon-reduction goals and preserve heritage.

COTE® Top Ten projects often embrace adaptive reuse to deliver high‑performance outcomes while honoring the value of existing structures. From industrial sites and civic buildings to educational facilities and cultural institutions, design teams are transforming aging assets into energy‑efficient environments that support new missions and community programs. Many projects include extensive envelope upgrades and high‑performance systems that dramatically improve comfort and operations, while others use selective structural interventions to emphasize daylight and access to nature and public spaces.

5. Climate-responsive urbanism is necessary 

In dense urban environments, buildings shape far more than their individual sites. They influence microclimates, mobility patterns, and public health throughout entire neighborhoods. With climate-responsive urbanism, architects are improving how they influence this bigger scale, using infrastructure and landscape to support mobility while mitigating heat and managing water.

By reframing buildings and developments as active participants in urban climate systems, architects and their clients are providing triple-bottom-line economic, sustainability, and social benefits. And they demonstrate how design decisions at the site level can meaningfully advance climate goals at the city scale.

Many recent winners of the COTE® Top Ten use climate‑responsive design to improve urban environmental performance and resilience. Common elements include massing, shading, and high‑albedo materials to cool surrounding streetscapes. Other examples are integrated stormwater systems that reduce runoff and interventions that improve energy efficiency and local air quality. Some projects center pedestrians, transit access, and bike infrastructure, reducing car dependence and expanding equitable access to daily needs. 

6. Healthy materials lead the way toward a resource-conscious future

The industry has prioritized material health, sourcing, and carbon impacts in accordance with the AIA Materials Pledge for some time. Material choices are central drivers of occupant health and long‑term environmental stewardship.

COTE® Top Ten-winning projects include healthier, biophilic, and low‑carbon materials that shape both building performance and occupant experience. They employ rigorous vetting, HPD- and EPD-certified materials, and collaborative specification processes that reduce toxins and improve indoor environmental quality.

Several advance mass timber and wood structural systems that trap carbon, support regional forestry economies, and create warm, daylight‑rich environments that enhance well‑being. Across project types, healthy, conscious material choices anchor a more balanced relationship between buildings and their surrounding environments.

Toward a more progressive design future

These trends amplify how architecture—and architects—can meaningfully respond to accelerating climate pressures. High performance, regeneration, and community resilience are no longer aspirational ideals but achievable outcomes when teams bring clarity, rigor, and creativity to the table.

Architects now have an expanding toolkit with new technologies, and they have access to more colleagues trained in systems thinking and sustainability strategies. Even within tight budgets or complex sites, architects retain significant influence over decisions that shape energy use, carbon emissions, ecological health, and human well‑being.

Going forward, architects are in a powerful position to continue shifting conversations toward reuse, toward landscapes that heal, toward buildings that support public health, and toward design processes that foreground equity. COTE® Top Ten projects offer a glimpse of a more resilient, livable future—and the role design can play in shaping it.

Winners of the 2026 AIA COTE® Top Ten will be announced at the annual Awards Gala, held during the AIA Conference on Architecture in San Diego (June 10–13).
