Design Excellence

We strive to create thoughtfully designed, high-performing places that enhance the user’s quality of life while addressing the urgent challenges of our time. We aim to embed sustainability, equity, wellness, and resiliency into every project. We target ambitious certifications and develop carbon-reduction strategies. We advance material health, adaptive reuse, and walkable urbanism. Backed by robust, human-centered research, we champion both innovative technologies and age-old techniques that help us contribute to a thriving, inclusive, and regenerative future for people and the planet.​

Carbon in Design

The built environment is responsible for approximately 40% of worldwide carbon emissions. To address our role in climate change both as an industry and within our firm, we strive to be carbon neutral. We are laser-focused on improving the energy efficiency of our projects and reducing the carbon associated with their construction and operation.

Our greatest carbon impact comes from the buildings and places we design. In 2024, we refined how we track project performance, grounding our design process in data and analysis to make decarbonization goals actionable. Nearly 99% of the projects we submitted to the AIA 2030 Commitment included energy modeling, up from 49 percent in 2023, thanks to a firmwide push to standardize performance modeling.

In 2024, we submitted 260 projects to the AIA 2030 commitment with 13 targeting net zero energy (NZE) and an average 59.91% reduction in predicted energy use intensity (pEUI). Based on our assumptions and carbon calculations, this level of performance may avoid up to 456,662 metric tons of CO₂ each year, an amount equivalent to removing 99,300 cars from the road for one year.

CASE STUDY: Taking a Passive Perspective
Phius Certification Success at La Mora Senior Apartments, Yonkers, NY

La Mora Senior Apartments in Yonkers is the nation’s first modular-built, Phius-certified senior housing. Designed for energy efficiency, comfort, and accessibility, it blends Passive House standards with neighborhood-inspired architecture—delivering affordable, high-performance homes for seniors while optimizing cost, schedule, and environmental impact.

High-Performing Projects

In 2024, we achieved several major certification milestones, and we increased the number of our projects targeting lofty goals. For example, La Mora Senior Apartments, a modular, affordable housing project in Yonkers, NY, is our first Passive House project certified by Phius (Passive House Institute US), and John Lewis Elementary School in Washington, DC, is the first school in the world with Zero Energy (Living Future), and double-platinum (LEED and WELL) certification.

High Performers Targeting Certifications in 2024

Sustainability is broader than third-party market standards, but certifications are useful guideposts to measure our progress. We have more than 100 projects registered and on a path toward certification (LEED, WELL, and Passive House, among others). We continue to increase the number of our projects targeting NZE, with 21 projects currently working toward that goal.

Annual Excellence Portfolio

Our Annual Excellence Portfolio (AEP) is an internal awards program based on the American Institute of Architect’s Framework for Design Excellence and our firm’s guiding principles. It measures our progress, honors our staff’s creative energies, and provides opportunities to track our success in reaching high-performance goals.

In 2024, 100 projects from 19 studios across our firm were submitted. The 22 short-listed projects, selected by an internal panel, demonstrate a clear vision, embody holistic high-performance strategies, and prioritize environmental stewardship. Of the short-listed projects, eight were selected by an external jury: Hazel Edwards, professor at Howard University’s College of Engineering and Architecture; Avinash Rajagopal, editor in chief of Metropolis; and Marcelo Spina, architect and founding partner of Patterns.

Materials

All aspects of the creation, specification, and use of materials have a major impact on the wellness of people and the planet. When selecting our materials, we comprehensively consider human health, climate health, ecosystem health, social health and equity, and circular economy principles.

 

In 2024, we joined the first industry-wide reporting cycle for the AIA Materials Pledge, submitting data from seven projects and becoming one of the first 92 firms to report—marking a major milestone in tracking the impact of our material choices.

 

We continued our office-specific material health visioning sessions, sparking dialogue, sharing case studies, and shaping our firmwide healthy materials action plan. We also launched updated materials specifications with baseline standards for all our projects, and we created enhanced pathways for targeting higher-impact outcomes related to health and carbon.

 

In the future, we will expand our specifications to cover more product types, updating the language in real time, and continuing our alignment with the AIA Materials Pledge. We are also in the process of integrating this into our AIA 2030 data collection and rolling out training to operationalize our sustainable materials vision and action plan across all teams.

CASE STUDY: Advancing Healthier Materials in Schools

Strategic Specifications at Tobin Montessori School & Darby Vassall Upper School, Cambridge, MA

At Tobin Montessori & Darby Vassall Upper School, our team prioritized healthier materials—navigating 7,000-plus products to reduce harmful chemicals. Through research, collaboration, and a targeted strategy, we specified 180-plus healthier materials, advancing sustainability and student well-being while highlighting the evolving challenges of achieving full material transparency.

Resilience

Resilient design is often narrowly linked to climate change and natural disasters, but its scope is much broader. True resiliency addresses infrastructure, economic, social, and environmental factors; it helps us prepare for both immediate shocks and long-term stressors. Our aim is to weave resiliency into every project. We strive to lead with passive design, as this design strategy provides the key to both reducing future climate emissions and improving livability and resiliency as the impacts of climate change take hold.

Resilient design identifies and reinforces successful patterns of sustainable urban settlement, improves those that are less successful, and applies the lessons learned—from the scale of the city to the building, room, and individual experience. This approach also promotes the reuse and adaptation of existing buildings.

Patterns of settlement that predate the automobile remain relevant models today. Even without a historic precedent, introducing walkable urbanism gives new places the best chance to become valuable, livable,
and high performing. Walkable communities are inherently more sustainable, as they support lifestyles less dependent on fossil fuels.

To build a resilient future, we must not lose sight of these core foundations. This is the inherent resiliency of urbanism that we are working to harness.

Research and Holistic Wellness

We strive to be curious—to enhance and advance our work through research that spans business, neuroscience, design, and environment-behavior studies to deliver evidence-based insights and strategic solutions. We invest in various research approaches, which have most recently included: studies into how workplace design can be an armature for creativity; multimethod post-occupancy evaluations of senior living communities to gauge user satisfaction and understand how design can influence quality of life; and research into connections between school design and educational outcomes.
