Our Approach to Sustainability Consulting

We work with the architect and building owner at the inception of every project to help turn their sustainability vision into a reality. We collaborate on the design, construction and operation of sustainable buildings to provide innovative solutions that greatly reduce operational costs and contribute to more resilient buildings, while meeting high standards for occupant comfort and health.


Integration Is Key To Higher Performance

Our green building experts work with our façade engineers and computational modelers in the early stages of a project to provide integrated information and advice to architects and building owners. This collaboration is essential to achieving optimal energy performance and the lowest greenhouse gas emissions.


Specialized Energy Modeling Capabilities

We perform whole-building energy analysis and modeling throughout the design process and into building occupancy. Our advanced computation modelers work with our sustainability team to develop new parametric analyses tools that allow us to provide first-of-their-kind data-driven strategies to maximize energy savings, increase occupant comfort, reduce carbon footprints and effectively incorporate renewable energy technologies.


Extensive Green Building Certification Experience

Our multidisciplinary staff consults internationally on the green building certification process for LEED, BREEAM and country-specific rating systems, and our services range from complete administration to specialized services. Our experience with all LEED rating systems and project types and our long association with the U.S. Green Building Council is well recognized, and leaders in our practice are LEED Fellows.


Content experts and educators

We were one of the first organizations to be invited to be a USGBC Education Partner, and thus we are recognized as offering best-in-class green building and sustainability education. We teach from large to small audiences; from architects and contractors to college students; and in community centers to board rooms. Our educators are USGBC Faculty and have lectured on a broad array of green building topics and provided continuing education and LEED exam preparation for many years.

Concepts and Tools

Energy Concepts

We perform whole-building energy analysis and modeling throughout design and into occupancy to predict and measure operational performance. We use advanced analytical tools to provide data-driven strategies that maximize energy savings, increase occupant comfort, reduce carbon footprints and effectively incorporate renewable energy technologies. Our team regularly develops in-house tools that enhance our modeling capabilities and ability to accommodate increasingly complex design problems. We also use simulation programs such as Weather tools, Ecotect, Therm, Window 6, DOE-2.2 (eQuest), EnergyPlus and BLCCA.

Concepts and Tools

Healthy Materials

We help project teams to identify and avoid sources of indoor contaminants, pollutants and hazardous chemicals in building products, materials and finishes. Through healthy materials research and specification review, and by employing our knowledge of the Red List and criteria for Environmental Product Declarations, we provide a healthy indoor environment for projects of all types and sizes.

Concepts and Tools

Integrated Design

As a participant in the development of the Whole Systems Integrated Process ANSI Approved Standard for Integrated Design, we are uniquely positioned to provide a whole-systems perspective on major design issues, and we actively foster collaborative work environments among multidisciplinary teams in order to achieve the highest level of integration. True design team integration can reveal opportunities for synergistic benefits. We start by conducting a sustainability charrette with all participants to ensure that project goals and objectives are clearly defined and understood.

Concepts and Tools

Net Zero Design

Our net zero energy approach begins with an extensive analysis of the climate, building site and surroundings so we may fully understand the available on-site resources such as solar, wind, vegetation and water. Because we can counteract external loads through passive design solutions, internal loads – which can account for 50% of a conventional high-performance building’s energy use – become absolutely critical. Our experience has given us a clear understanding of the detailed functionality, use and internal loads (people and equipment) that will be present in the space.

Concepts and Tools

Parametric Modeling

Our team of experts uses complex simulation programs to explore innovative ideas and to establish and achieve targeted energy reductions in the early design phases. We employ parametric modeling for optimization studies, exploring energy conservation measures that reduce building loads and increase operational cost savings. Our recommendations help stakeholders and design teams make informed decisions, driving their designs toward energy efficiency while remaining within budget.
