2019 CLARK NEXSEN SUSTAINABILITY REPORT

INTRO In 2019, Clark Nexsen benefitted from an increasing number of committed professionals advancing integrated design in our practice with an emphasis on developing effective tools and training. We are building a design infrastructure that makes tangible our belief that sustainable, resilient design is a social imperative for our industry. Within our 2019 Integrated Design Report, you will find insights and initiatives intended to empower our people and clients to pursue ever greater levels of sustainability.

Our key achievements from 2019 include: •

• • •

Creating and rolling out tools for performance monitoring, including tracking performance goals in Vision and embedding the COTE Top 10 metrics in our Revit template, “Appendix G” Expanding our Building Science Group efforts and gathering post occupancy data Increasing our focus on carbon, both embodied and operational Facilitating training by external experts to support project managers and design leads in guiding the integrated design process

Data has become a centerpiece of our integrated design methodology. Post occupancy data is a critical component of the design feedback loop, enabling us to learn from past design decisions and informing future solutions. In addition to propelling us toward achieving the 2030 Challenge, this information is invaluable to clients as they evaluate the ROI of sustainable and resilient design.

By providing energy and cost outcomes, our designers are able to present the practical case for sustainable design alongside the scientific one.

Carbon has emerged in a new way in the conversation around sustainable design, with an increasing focus on embodied carbon. We are committed to being on the forefront of this discussion and mitigating the carbon impacts of our work, both embodied and operational. We believe that by viewing the building and material lifecycle holistically, we can achieve significant carbon reduction.

To that end, our designers participated in the Large Firm Round Table 2030 Carbon Summit in Chicago and 2030 Carbon Net Zero conference in Los Angeles, and we held collaborative workshops with external experts to raise awareness and knowledge.

As we look to 2020 and beyond, we will prioritize carbon tracking and create a system for specifying healthy, low carbon materials and structural systems. We are also committing to the 2030 Challenge for Embodied Carbon. Our design teams will take advantage of new tools including a Vision system for performance metrics and the new “Appendix G,” a Revit-based template based on the COTE Top 10 metrics. We anticipate these new tools and systems will rapidly advance our integrated design effort, enabling us to achieve greater project performance across our portfolio.

We envision a world where high performing design solutions have addressed climate change, are resilient, and promote a vibrant and healthy social environment. Our plans are reflective of our belief that every market we serve and every aspect of our practice can make meaningful contributions to preserve our world for the future. We encourage you to join us in this pursuit.

Sincerely,

Clymer Cease, FAIA, LEED AP Chairman of the Board

EXECUTIVE SUMMARY

M E R G I N G O F V I S I O N W I T H I N T E G R AT E D S U S TA I N A B L E D E S I G N

“TOGETHER WE DISCOVER, INSPIRE, AND SHAPE IDEAS THAT TRANSFORM OUR WORLD” Integrated Design defines our approach to continuously elevating the performance and sustainability of our projects. As a team of 400 professionals, we have a substantial opportunity to reduce the environmental impact of our projects, support the economic viability of our clients and communities, and deliver long-term positive results for society.

We see sustainability as inherent in our vision to discover and shape ideas that transform the world.

By leveraging our transdisciplinary practice to capitalize on the intersections between internal disciplines, we share expertise, gain new insights, and uncover innovative solutions to meet the challenges of sustainability and resilience. Our architects, engineers, planners, interior designers, and support professionals serve a wide range of industries including federal, higher education, science and technology, K-12, industrial, healthcare, transportation, and infrastructure.

Our 2019 Integrated Design Report captures key progress from the last year, including the development of additional tools, systems, and training that will further enable our people to design high performing, resilient projects. We have improved our software infrastructure to include tracking project performance goals in Deltek Vision and embedding the COTE Top 10 metrics in our Revit template, “Appendix G.” Additionally, we have expanded our Building Science Group efforts to include gathering post occupancy data and carbon tracking.

Throughout this report, you will see evidence of our commitment to leveraging data to continuously improve our design methodology and project results. Better performance tracking, post occupancy data, and carbon tracking (both embodied and operational) will be central to our ability to achieve the 2030 Challenge. Of equal importance in our industry is the need to provide practical financial data to clients debating sustainable design elements; a blend of cost estimating, projections, and proven post occupancy figures enables us to demonstrate how and where both upfront and long-term cost savings exist.

The achievements of 2019 serve as a springboard for what’s to come in the next decade.

The infrastructure we are creating is a foundation for achieving a carbon-neutral design portfolio by 2030. We recognize there is more work to be done to accomplish this lofty goal, and our ongoing action items will guide us as we design for a better, brighter, more sustainable future.

BUILDING SCIENCE GROUP The Building Science Group serves as a companywide resource for energy modeling and analysis with core goals to improve project performance and generate long-term operating cost savings for our clients. Providing dedicated, full-time access to energy modeling from concept design to construction documents, this group is integral to informing design decisions and improving Energy Usage Intensity (EUI) outcomes. Within the greater picture of our integrated design effort, this achievement is central to reducing environmental impact and meeting the 2030 Challenge.

ENERGY MODELING Complex design solutions require robust analysis. Our energy modelers provide high level early analysis, deep dive analysis, and compliance modeling to complement and inform the design process from kick off to completion.

High level analysis supports early concept design and may include massing/orientation studies, daylighting optimization, and energy analysis. Deep dive analysis assesses and answers more challenging questions that require thorough investigation – envelope constructions, building systems, moisture transmittance, and computational fluid dynamics, among others. Compliance modeling creates full scale energy models for code compliance or certifications such as LEED or Green Globes.

INTEGRATING BUILDING PERFORMANCE WITH SITE DESIGN Our goal is to integrate the unique qualities of any given site with the building and site infrastructure systems in order to maximize energy performance while protecting natural resources. Using a careful bioclimatic analysis combined with passive solar strategies and renewable energy sources, our team works to minimize energy usage while restoring the environment. Our approach is to focus on helping clients optimize their building systems to increase reliability and resilience, lower costs, and protect the environment.

2019 CLARK NEXSEN SUSTAINABILITY REPORT

SUSTAINABLE INTERIORS Our interiors team sees their role as critical not only to creating an environmentally respectful design, but also to supporting human health and wellness in the built environment. Responsible for specifying the materials and products people interact with every day, the interior design team carefully selects materials that are environmentally friendly, regional, and made of high recycled content. In addition to ongoing education and research regarding non-toxic and sustainable materials options, this group is conducting research on the impact of sustainable interior spaces on workplace productivity.

2019 CLARK NEXSEN SUSTAINABILITY REPORT

SUSTAINABLE INFRASTRUCTURE Our Sustainable Infrastructure Envision Team guides Clark Nexsen's Infrastructure and Transportation departments to design more sustainable site/civil and landscape infrastructure. This group utilizes the Envision system to engage stakeholders, evaluate projects from multiple perspectives, and develop solutions that address life cycle costs and long-term environmental challenges.

RESILIENT DESIGN With 50 percent of the U.S. population living along the coast, our waterfront engineering team plays a high profile role in researching and developing strategies to adapt to rising sea levels. Recent research efforts include a community-driven resilient master plan developed for the Virginia Beach area, which examined current flooding and projected sea level rise as well as neighborhood layouts to reimagine the area for decades to come. Designing for resiliency in coastal settings is just one aspect of delivering sustainable solutions for our clients.

2019 CLARK NEXSEN SUSTAINABILITY REPORT

PROJECT GOALS Essential to the success of every integrated design process is setting clear, meaningful goals for the project and communicating these goals clearly and efficiently throughout the design team. To that end, Clark Nexsen has developed a system for facilitating the establishment of goals early in the project, and documenting those goals in a way that is trackable and easy to share. Our accounting and project management software, Deltek Vision, has been customized to allow design teams to enter their project's goals into a database, incorporating the aspirational goals of the client and designers with clear, measurable sustainability goals within the categories of Habitat, Energy, Water, and Materials. This data is then linked directly with Clark Nexsen's intranet, called "the Cube," making the information easily accessible to the entire design team, ensuring everyone is working together toward the same goals.

SUSTAINABILITY TOOLS A major initiative in growing Clark Nexsen's proficiency in Integrated Design has been the establishment of a set of sustainability tools and resources available to design teams. Through our intranet site, called "the Cube," we have consolidated a number of useful documents and tools including AIA COTE documents, LEED resources, and tools for specifying green materials. In addition, Clark Nexsen has developed a number of in-house sustainability tools, including our "Appendix G." This tool serves as a summary of the AIA COTE Top Ten Toolkit, giving design teams a concise checklist of issues to consider throughout the life of a design project. Appendix G is linked into our Revit template, ensuring that each project addresses these issues and that everyone working on the design documentation has easily access to the established sustainability goals for the project.

PAT H T O N E T Z E R O

By signing on to the AIA 2030 Commitment in 2015, Clark Nexsen has joined a growing number of firms that are measuring the energy performance of their buildings and working toward designing all new buildings and major renovations to be carbon neutral by the year 2030. The 2030 Commitment requires design teams to track the predicted Energy Use Intensity, “pEUI,� measured in kBtu/sf/yr. The 2030 Challenge has established a current goal to achieve energy performance of 70 percent better than the national average per building type, which requires design teams and building owners to work closely together and share performance priorities. Clark Nexsen is currently monitoring more than 50 projects over a cross section of building types. While the pEUI reduction is not reaching the 70 percent goal, the pEUI reductions are significantly less than the baseline across all building types.

By analyzing the data we collect for the 2030 Commitment, Clark Nexsen has generated a number of useful insights about our progress towards carbon neutraility. By tracking our data by office, project type, project size, and even by project manager and partner-in-charge, we have better identified our strengths and weaknesses, Projects Modeled and developed targeted strategies for improving our performance. In particular, the two graphs below show how we are doing in terms of pEUI reduction and energy modelling. The graph average pEUI Reportingon Yearthe left shows our  reduction by year, which is on par with our peers. While we are not yet meeting the target of 70% reduction, our 2015 2019 70 performance is steadily increasing over time. The graph on the right shows the ratio of our projects that have or will be modeled vs the projects that will not. By modeling 62% of our projects, Clark Nexsen has outpaced the AIA national average for 2019 of 43%. In 2020, Clark Nexsen will strive to improve on that number with the goal of significantly reducing our average pEUI. Average of Percent_PEUI Reduction by Reporting Year

GEORGETOWN CAR BARN ADAPTIVE REUSE Georgetown University, Washington, DC An ever-growing institution, Georgetown University saw an opportunity to repurpose an 1800s mechanical car building by transforming the first floor spaces to house the University Press and Master of Arts in Government program. Known as the Car Barn, this historic building is situated along M Street at the end of the Key Bridge and was originally used to house and maintain the city’s streetcars.

The adaptive reuse was completed with sustainability in mind. Care was taken to maintain the historic integrity of the building’s character, with the existing structure being reused and repurposed. This effort minimized embodied carbon by giving new life to the existing facility with no new construction. The large arched doorways, previously used for the streetcars, were re-opened and infilled with a glass-fin curtainwall system to promote transparency and create a dramatic lobby and student lounge area.

The bright, modern interior benefits from

added daylight as windows were restored and the barn doors opened up. Occupancy and daylight sensors control the interior lighting, ensuring adequate light while minimizing the use of electricity.

Occupant comfort in the new classrooms, offices, and conference rooms is assured with an energy efficient HVAC system that employs demand control ventilation with an air-side economizer and water-source heat pumps. The system utilizes variable speed technology on hydronic pumps and airhandling unit motors to properly match the building energy use to the building load.

The thermal envelope was improved to maximize energy efficiency, adding an air barrier and thermal insulation to the existing, uninsulated exterior walls. New wood windows, matching the originals but with increased efficiency, were incorporated into the facade, bringing natural light into the space and offering views to the famous “Exorcist Steps,” which were preserved along the building’s exterior.

FERGUSON HEADQUARTERS Newport News, Virginia Facing a need to expand their headquarters in Newport News, Ferguson partnered with Clark Nexsen to create an amenity-rich, energy efficient, collaborative space for their associates. At the core of its design is a shift towards transparency, openness, and connectivity, and sustainability both within the company and the community at large.

The design solution kept a fairly narrow footprint in the optimum building orientation to maximize both daylighting and views, benefitting occupant well-being and reducing the need for artificial lighting.

The open office concept reduces material use, and interior rooms such as flexible offices and meeting spaces feature glass wall systems to allow daylight through to the building core. The low solar heat gain coefficient of the glass has a significant impact on the building’s energy efficiency, and shading devices on the east, south, and west facades further control glare and heat gain without interrupting views.

Both inside and outside, the design prioritizes creating opportunities to promote interaction and community. A

multilevel glass atrium, open lobby space, and monumental staircase connect multiple levels and encourage people to use the stairs rather than elevators. Ferguson associates have access to a variety of outdoor training and dining spaces and a rooftop terrace. Additionally, prior to the construction of HQ3, the site served as a ‘city center’ for residents to gather, and the design preserves community access. Rather than walling this site off from the city, a pathway leads under the building and into the plaza allowing the public to enjoy this outdoor plaza.

The HVAC system has a number of features that contribute to the significant reduction in pEUI. An energy recovery ventilator transfers heat between the exhaust and outdoor air streams using a total enthalpy recovery wheel. A thermal storage system is used to shift electrical demand for cooling from peak daytime hours to off-peak nighttime hours by enabling the chillers to produce ice at night, which is then melted during the day while the chillers remain off. Both the cooling and heating systems also feature a high degree of controllability, allowing them to meet demand with very little waste.

With two programmatic bars that meet to form an “L” shape, the building is aligned on an east/west axis with good solar orientation. Throughout the building, energy efficiency is supported with exterior sun shading and different glazing types.

For example, a two-story, south-facing glass curtainwall in the commons space was optimized toward prominent views.

An external sun shade and ceramic fritted glazing minimizes solar heat gain and reduces glare into this space while allowing for balanced daylighting.

An on-site bio-retention pond handles 100% of the stormwater. In addition to sustainable design features of the building itself, its location on the community college campus reduces individual driving trips and vehicle emissions as students can readily access all needed courses by walking.

CAROLINA DAY LOWER SCHOOL Asheville, North Carolina The Lower School at Carolina Day serves first through fifth graders in an inquirybased learning environment, focused on supporting student growth and providing problem solving opportunities.

Our designers worked with school representatives to create a solution that responded to their needs, enhanced indooroutdoor connectivity, and positioned the school to meet changing trends in K-12 education.

The resulting renovation and addition has formed a facility that instructs by design and provides light-filled, engaging spaces for students, teachers, and staff. More than 80% of the project is adaptive reuse, with 100% of the existing structure and roof decking reused. Additionally, the use of wood as the primary building material for the addition reduces the project’s embodied carbon.

The building serves as a teacher, with windows into interior walls to reveal the MEP systems and a butterfly roof that directs rainwater into a bio-retention pond.

Outside, the courtyard is more than a

place to gather, learn, and play; it handles 100% of stormwater (roof and site) via the retention pond and features native, educational landscaping as well as earthen berms for free play.

The school is surrounded by Asheville’s outdoor beauty and care was taken in the renovation design to reinforce this indooroutdoor connection. Generous natural light abounds, with 95% of occupied spaces having direct exterior views and receiving natural daylight. In particular, all classrooms have direct views to the outside while clerestory windows serve to balance daylighting. In the gymnasium, the conversion of existing ventilation panels to clerestory windows allows the gym to be used with no artificial lighting at most times.

A new HVAC system improved both climate control and energy efficiency. The renovated school now uses 42% less energy than the baseline. Additionally, the R-23 walls exceed the North Carolina energy code by 53%.

By integrating sustainable design elements along with K-12 design best practices, the school reflects its region’s commitment to protecting the environment while enabling children to learn and explore.

M�CORMICK ROAD HOUSES RENOVATIONS University of Virginia, Charlottesville, Virginia As the primary freshmen housing complex at UVA, the McCormick Road Houses play a pivotal role in the student life experience. This substantial complex includes 10 individually branded “houses” accommodating nearly 1,400 students.

Prior to their renovation, the buildings lacked many of the amenities found in newer residence halls on UVA’s campus. The university partnered with Clark Nexsen to create a reimagined housing environment that helps to attract great students and promotes an engaging freshman experience.

Throughout the houses, new interior finishes create a contemporary aesthetic.

The introduction of a new HVAC system, fire protection, elevators, and upgraded electrical and telecom systems ensure a safe, comfortable, and functional environment. The design team also seized opportunities to go above and beyond a basic systems renovation and transform key social experiences for first year students.

Openness and transparency are driving themes in shared spaces. The commons spaces now feature floor-to-ceiling glass

storefront and modern furnishings, offering students variety of areas for socialization or study. The stairs have been reimagined to support students’ sense of community, with large landings and open sight lines from one side of each house to the other.

The transformation of “The Castle,” a dining and social space, represents a small but very significant component of this project. By opening the exterior walls and introducing a lantern-like addition on the corner, The Castle and its surrounding outdoor plaza have become a vibrant hub of activity.

Key sustainability features include the incorporation of total energy recovery wheels into the Dedicated Outdoor Air Systems (DOAS) to recover energy from the tempered exhaust air and transfer it to the untempered incoming outdoor air.

This, coupled with the addition of new insulation at the roof and new energy efficient windows, has help to significantly drive down the energy consumption of the project. In addition, by reusing 97% of the existing structure and envelope, UVA has ensured that these facilities will last for many decades to come.

HEALTH & HUMAN SCIENCES BUILDING Western Carolina University, Cullowhee, North Carolina The Health and Human Sciences Building was the first facility constructed for Western Carolina University’s Millennial Campus, establishing an approach to development that emphasizes sustainability in conjunction with cutting-edge research facilities. The 160,000 square foot building provides state-of-the-art learning environments for the five departments and nine disciplines within the health sciences college.

Nested into the mountainside, the design is a direct response to the site topography and solar orientation. Mapping slopes less than 30 percent defined buildable area limits, informed the project location, and delineated its northernmost extents. To optimize the solar orientation and minimize the impact of the building, the southern boundary was defined by a natural basin in the site. Stepping the design with topography, the facility rests between the defining elements, conforming to the site.

This design strategy minimized the scale, promoted interior/exterior relationships, and was the genesis for a large roof garden.

As an extension of the site, the roof garden

replicates the form of the basin to restore the natural environment. The garden is home to native medicinal plants indigenous to the Appalachian and Cherokee people and provides a tranquil setting rich in colors, textures, aromas, and sounds to promote renewal and inner well-being. Such siteinfluenced responses generated smaller floor plates, enhancing opportunities for natural daylighting and resulted in a contextually appropriate solution with a human scale.

Natural light is shared throughout the building, introduced through an expansive, south-facing atrium curtain wall and distributed to inner offices, corridors, and small gathering areas through interior glazing. Sunscreens provide thermal comfort by limiting direct solar exposure to 3 percent annually, while providing ambient natural daylighting sufficient for 75 percent of lighting needs each year. Teaching spaces, including specialized labs and simulation environments, are organized along the northern edge with diffused daylight and clerestory views to the ascending elevations and natural setting.

PERPETUUM - METLIFE COMPETITION New York City, New York The international MetLife competition provided a platform to research sustainable and energy efficient strategies for both new and renovated high-rise buildings. Clark Nexsen’s submittal, PERPETUUM, takes a holistic approach to the design challenge of renovating an existing high-rise building and implements strategies beyond merely the introduction of a new exterior skin. The design examines opportunities to not only enhance the aesthetic of an architectural icon, but also to address social, economic, and environmental issues in the design solution.

Modern workplaces rely on collaboration and informal gathering, often fostered by daylighting for a bright, open environment.

PERPETUUM proposes to programmatically add atrium amenity spaces for both the public and building users to enjoy, located at the street level and the upper floors. On the upper floors, these public spaces are shared between four floors and stacked on top of each other to activate the southern side, providing increased opportunities to harvest daylight and views.

The cladding system is a double glass wall envelope used to enhance the passive solar capability of the tall structure. The double skin is designed to be a unitized system, which will reduce on site construction and limit interruptions at street level caused by construction operations. On cold days,

the double skin is enclosed and provides additional insulation through the deeper air cavity, while on warm days, the double skin is opened to the outside to provide fresh air intake and improved indoor air quality.

The design team also considered solutions for the demolition and disposal of the existing cladding materials. PERPETUUM proposes to donate the precast concrete panels to local municipalities for reuse in flood protection measures along Manhattan’s river fronts, a solution that aligns with ongoing efforts by the city to mitigate future damage caused by catastrophic flooding as seen in Hurricane Sandy. Demolition of the existing skin would also entail harvesting the glass and curtainwall framing to be recycled, thus bypassing the waste stream.

PERPETUUM proposes a mechanical system involving the installation of a new mechanical shaft to create additional natural ventilation opportunities through the height of the building. The shaft creates a stack effect, which has air intakes and pressure reliefs strategically located throughout the building.

PERPETUUM endeavors to improve the vitality of the MetLife building by honoring its history and iconography through sustainable strategies and improved spatial quality and variety indicative of a contemporary work place.

Demand for energy efficiency well established The vast majority of projects today incorporate some degree of energy efficient design.

Owners and operators, looking through a purely financial lens, want to reduce the cost of utilities such as water, gas or oil, and electricity. Equally significant, the upfront cost of many of the more efficient systems and materials is now aligned with traditional options, making the more efficient choice the obvious one.

At the beginning of any significant project, building and infrastructure owners are balancing multiple variables and priorities ranging from initial design and construction costs, to long-term operational costs, to local, state, and federal regulations or potential tax breaks. Increasingly, the pEUI of a facility comes into play in these conversations as it correlates to both reduced operational costs and lowered CO2 emissions. While reduced operational costs have arguably become the most significant driver of business investment in green construction, the reduction of CO2 emissions can also be tied to business reputation objectives and regulatory mandates.

There is substantial market opportunity for design firms focusing on high performing, sustainable design, as the perception of sustainability has shifted from purely reputational to meaningful in terms of economy and practicality.

2019 CLARK NEXSEN SUSTAINABILITY REPORT

Increasing demand for a holistic approach to design Approached holistically, sustainable design positively impacts every aspect of our built and natural environment.

More recent certifications such as WELL Building are clear validation that occupant well-being and the overall health of people is as significant in design today as traditional “sustainability.� Green schools present new opportunities for hands-on learning; sustainable office environments promote healthy, productive occupants; and environmentally-friendly infrastructure protects our valuable water, energy, and material resources. The business case for green building encompasses human capital as well as operational costs. The USGBC cites research indicating that employers with more rigorous environmental standards are finding as much as 16 percent increases in labor productivity, and those with better daylighting note a 27 percent reduction in the incidence of headaches.

As a transdisciplinary design firm of architects, engineers, planners, and interior designers, we are uniquely positioned to meet market demand for a holistic approach to sustainable design. Our design process crosses disciplines to gain unique insights that maximize sustainable opportunities, with more than 40 percent of our design professionals LEED and/or Green Globes accredited. Our method leads to the development of buildings and infrastructure that protect our clients’ bottom line, brand reputation, and the environment.

Increasing demand for resilient design Aligned with sustainability, resilient design incorporates principles that better prepare our buildings and infrastructure to withstand current and future climate change. With 50 percent of the U.S. population living on or near the coast, we must develop solutions that are resilient to coastal issues such as sea level rise. The implementation of resilient design principles protects owner and insurer investments, both coastal and interior, by reducing disaster-related costs, strengthening insurability, and mitigating the risk of credit downgrades. The business case for resilient design as a component of sustainability is easily evident, and we strive to integrate these principles into every project. Additionally, as a design firm that frequently works with various departments of the DoD, Homeland Security, and other government installations, we understand resilient design principles as they correspond to manmade events as well as natural disasters. To develop critical communication centers, hospitals, and various federal facilities that can remain operational in any event, the integration of resilient design is a necessity. Just as we view good design as inherently sustainable, we view good design as inherently resilient.

• The Building Science group will begin to take a more comprehensive approach to tracking Post-Occupancy energy data from past projects to better understand pEUI vs actual EUI. • We will enhance our annual performance review format for employees to include language regarding demonstrated efforts to pursue building performance metrics including embodied carbon.

Improving Knowledge • The Sustainability Network will roll out and provide training sessions for the new sustainable tools and resources for the firm including Appendix G and establishing project goals and tracking in Vision.

• Employees will be encouraged to attend webinars, seminars and conferences on low carbon materials and structures in addition to developing the knowledge and skills for leading effective Integrated Design charettes.

• We will continue to encourage and pay for all members of the Sustainability Network to get registered in additional sustainable and resilient building and infrastructure design rating systems including LEED, Green Globes, Living Building Challenge and the Well standard.

Project Delivery • Design teams will begin to use the new “Appendix G,” a revit-based project performance template, which is based on the complete system of COTE Top 10 metrics.

• We will continue to develop the internal standards/best green practices narrative and include embodied carbon for each building type.

2020 Action Plan (cont.)

• The Building Science Group will continue to develop the policies regarding energy modeling and carbon tracking on projects in conjunction with the mechanical department and integrated design group.

Sustainable Operations • Each office will have a Sustainable Office operations committee dedicated to finding opportunities to reduce energy and carbon footprint. The committees will use the MIT Sustainable Office System as a guide to develop new ideas and benchmark their office against other offices.

• We will institute companywide transportation policies to reduce carbon emissions by encouraging the use of fuel-efficient cars, hybrid vehicles, and electric cars. The company will look into the next fleet of leased cars to be fully electric.

• We will continue to develop the policies to reduce waste by encouraging the use of electronic documents and forms, setting copy machines to double sided, encouraging recycling, packaging policies for lunch and learns, starting composting systems in offices, and reducing the number and size of hard copies for project submittals to reduce waste.
