Sustainable Building Design
Designing sustainable buildings for a better future
Sustainability is at the heart of design. Our commitment to reducing greenhouse gas emissions and prioritizing health is reflected in our innovative architecture and engineering projects worldwide. By prioritizing sustainable building design, 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 well-being at a corporate level, our team offers guidance.
As a multidisciplinary 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.

Building retrofits and sustainability go hand in hand. Rising costs, climate imperatives, aging infrastructure, and evolving performance standards make it essential to rethink how we approach existing buildings. Today, retrofitting isn’t just an opportunity—it’s a critical step toward a sustainable future. Hear our thought leaders break down the transformative potential of building retrofits.
