Buildings, transportation, and utilities present some of the most significant opportunities for addressing climate change and sustainability in the built environment.
Through our work for clients and our operations and research, we directly address 14 of the UN SDGs. Our annual Environment, Social, and Governance (ESG) report shows our commitment to progress.
Our global team combines expertise from planning, policy, economics, environmental and computer sciences, project management, engineering, and corporate strategy.
Keeping your goals on track.
We help write the national and international standards in sustainability, and we know how to help our clients meet and exceed those standards.
Working with clients to identify and set sustainability goals, we identify cost-effective strategies to achieve them, and then monitor, manage, and certify against those targets.
We also create custom frameworks aligned to corporate vision and strategy and address unique project opportunities or constraints.
Sustainability ambitions driving better results.
Bold design decisions informed by rigorous modeling and testing—that’s the power of our whole-systems, evidence-based approach to sustainability.
Focusing just as much on the buildings as the human experience within and around them, our integrated team of architects, engineers, urban planners, and user experience designers harness the power of analytics and deep technical expertise to achieve ambitious sustainability targets—and whole-building performance.
A zero-emissions world brought to life.
Our vision for a sustainable, prosperous, more equitable future can only take shape with the most advanced engineering systems in place. From high-performance building services design—zero-emissions buildings, microgrids, healthy and productive indoor environments—to transportation infrastructure, advanced mobility, and water treatment and reuse, our global team of designers and engineers brings deep technical expertise in horizontal and vertical infrastructure to every project, seeing, appreciating, and leveraging the interconnectedness of the whole system.
Beyond the build.
We empower building investors, owners, and occupiers to operate and maintain their investments effectively and efficiently through a structured, auditable approach.
This means we go beyond the traditional checks and balances approach of conventional commissioning engineers. We walk alongside our clients throughout the process—from design review, through installation, testing, and monitoring—making sure they know not only how to use, but how to maximize and troubleshoot their new systems.
Our systems only work if our clients know how to use them to their greatest potential.
We support property owners reporting asset performance against Environmental, Social, and Governance criteria for assessment for benchmarks such as GRESB and CDP.
Empowered decision-making starts with the right insight.
We shape effective sustainability policies, regulations, codes, standards, and development strategies, helping public- and private-sector clients adapt to an ever-evolving policy landscape. We accelerate the achievement of sustainability goals for organizations, all levels of government, and infrastructure, district, and masterplan developments.
Our ability to model, test, and evaluate impacts means our clients can make informed decisions—and keep stakeholders engaged and informed.
