Sustainability & Building Performance
Designing sustainable buildings for a better future
Sustainability is at the heart of design. Our commitment to reduce greenhouse gas emissions and prioritize health and wellbeing is reflected in our innovative architecture and engineering projects worldwide. By prioritizing the design of high-performance sustainable buildings, we transcend expectations and advance our communities into the future. Our goal? To unlock the full potential of your projects.
We consult, plan, and design at every scale of built, natural, and organizational environments. Whether you’re exploring opportunities to achieve a net zero building, reducing your real estate carbon emissions, assessing and planning for the impacts of climate change, or aligning your commitments to carbon, climate, and wellbeing at a corporate level, our team offers guidance.
As a multi-discipline design firm, we embrace an integrative design approach in every project. We help you make informed decisions by integrating site performance modeling, life cycle cost analysis, passive and net zero design, third-party certifications, and post-occupancy assessments. Our approach addresses climate risks, vulnerabilities, regulatory requirements, operational and embodied carbon emissions, and resilience—all to improve health and wellbeing outcomes for every community member.
Why do we do this? Because we believe that taking a sustainable approach is not just smart practice—it’s essential for our shared future.
Net zero building design
Our success in net zero energy and net zero carbon building design stems from a deep understanding of the complexities in both new construction and existing building retrofits. We cover the full spectrum of planning, design, infrastructure, and operations to address both operational and embodied emissions. We carefully evaluate local and regional utility infrastructure, consider long-term climate action plans, and we stay ahead of the evolving energy transition landscape.
