Exploration & Expertise Our awareness and accountability for our influence on the natural environment reflects our commitment to design excellence.

High-Performance Design

Decarbonization

Responsible Materials

Using experience, data and analyses, we uncover and share information so owners and operators can make informed decisions for their projects.

We have the team, technology and the tools to help our clients determine and achieve goals for efficient building operations, maintenance and occupant wellbeing.

We help clients explore and manage embodied, operational and transportation carbon emissions.

While energy efficiency and clean energy are still important parts of the decarbonization conversation, there is more to consider and address as we work to enhance the built environment. Our experienced professionals provide, measure and evaluate a range of carbon-reducing and carbon-free options that align with clients’ project and operational goals.

Stakeholders make thousands of decisions during the planning and design of a project. Selecting and specifying materials and products that prioritize people and planet is one of our most valuable services as demands accelerate for high performing and responsible solutions.

Our Commitments We serve as champions of sustainable design practices and are signatories of industryleading sustainability commitments. Together, we can build a sustainable future.

The AIA 2030 Commitment aims to transform the practice of architecture to respond to the climate crisis in a way that is holistic, firm wide, projectbased, and data driven, delivering carbon-neutral buildings by 2030.

LEO A DALY Engineering Qualifications

The AIA Materials Pledge shifts how the industry evaluates the products and finishes specified on a daily basis. Participants commit to five overarching statements that will lead to more intentional product specifications across their portfolios over time.

The Structural Engineers 2050 Commitment Program is designed to ensure substantive embodied carbon reductions in the design and construction of structural engineering profession all in the name of achieving zero net carbon structure by 2050.

Wellbeing What surrounds us matters.

Research and experience show holistic planning and design is necessary as it considers and influences both human and environmental health. Our design process focuses on wellbeing across scales – from individual spaces within buildings to buildings themselves, and beyond to the context of neighborhoods and communities.

The MEP 2040 Commitment seeks to dramatically reduce the embodied carbon emissions associated with mechanical, electrical and plumbing systems through data-driven, collective action among committed design firms and supporting organizations.
