Legence - Sustainability Report 2023

Sustainability Report

A MESSAGE FROM OUR CEO

We are working to support our partners, their communities, and the natural world we share.

Legence is a legion of companies with best-in-class craftspeople, consultants, contractors, engineers, and professionals working in tandem to foster a sustainable future by championing building efficiency today. Through our work we strive to radically improve the performance of the built environment at speed and scale.

We are laying the groundwork for our own sustainability program, beginning the process by standardizing a level of excellence across our companies from health and safety, environmental performance, and good governance, to diversity, equity, and inclusion (DEI), and career development. We are innovative, we are passionate, and we are walking the talk. That is why our mandate is to elevate our people and processes.

Safety is at the heart of our strategy because we’re a people business. Especially when we’re on construction sites every single day, whether we are wearing a hard hat and welding pipe, servicing equipment, conducting a building energy audit, or bending sheet metal, we’ve got to be safe. It’s simply non-negotiable. We have started collecting data to map our environmental performance through a Greenhouse Gas (GHG) Inventory and set forth a roadmap to get to Net Zero by 2040. Our career development pathways are upskilling our workforce to be leaders in the industry, and we are outlining strategies to foster and promote DEI throughout our companies.

Our governance approach, led by our Executive Leadership Team, places emphasis on strong policies, collaboration, and transparency. This three-pronged approach of environmental, social, and governance (ESG) strategies helps us win every day. On jobsites, in our design studios, and during client interactions, we are putting our roster of change-makers and subject matter experts into practice.

Throughout this inaugural Sustainability Report you will see how we internalize our mission to improve the performance of the built environment and we are eager to continue to share our progress year after year. We share this journey with our employees, investors, industry peers, and customers because we understand that everything we do makes a difference. Today, tomorrow, and for the future. As one of the largest ESG consulting practices in North America, our north star is sustainability, and we are constantly working to attain that standard of performance through everything we do.

WE ARE A Safety-First Culture

We pride ourselves on safety, it is a practice ingrained throughout our business units and a promise we keep by supplying our teams with industry leading tools, equipment, benefits, and protocols. Safety starts with our leadership and flows into our day-to-day operations. At our facilities, we promote occupant health through improved indoor air quality, access to daylight and natural ventilation, health and wellness amenities, as well as healthy building materials and furnishings. Many of our business units also have a dedicated safety lead to facilitate safety initiatives onsite while our Legence-wide safety communication plans help drive our safetyfirst culture and instill best practices throughout our operations.

OUR COMMITMENTS

ƒ Maintain a safety-first culture, promoting the health and wellness of our team and an incident-free workplace

ƒ Promote occupant health at our facilities through:

Improved indoor air quality

Access to daylight and natural ventilation

Health and wellness amenities

Healthy building materials and furnishings

Safety is fundamental to every business decision

Best-in-Class Safety Task Force

Safety for all requires a collaborative team approach.

We created a Best-in-Class (BIC) Safety Task Force to act as a foundation for driving safety initiatives and their implementation across our legion of companies. In early 2021, we ran a BIC Safety Task Force study across Legence to understand how our organization as a whole can provide a best-in-class safety environment to our 4,000+ employees. To lead this Task Force, we hired a Director of Environmental Health and Safety (EHS), Zach Gill, whose focus is to deliver on our commitment to safety. To date, we have launched three safety initiatives aimed at lowering incident rates for our most vulnerable employees, those within their first two years of employment.

WE FOCUSED ON

ƒ Awareness

ƒ Mentorship

ƒ Pre-Task-Planning

Each initiative involved team members from across our business units to develop a minimum standard of expectation. We also have a charter and sample program, and track key performance indicators (KPIs) associated with these programs monthly where they are reviewed by the EHS Director and the executive committee for continuous improvement.

Investing in Safety

Whether our people are working in the office, on a job site, or anywhere in between, safety is our number one priority.

HARD HATS TO HELMETS

Legence provides premium, high-quality personal protective equipment (PPE) to our business units. We recently upgraded our team members’ traditional hard hats to new helmets complete with better shock absorption and fittings. The cost of more advanced hard hats is well worth the investment to ensure our people are safe.

INCLUSIVE SAFETY PRACTICES

Legence is determined to promote inclusivity within our organization, especially when it comes to keeping our team members safe. We do this in two ways:

ƒ To ensure safety protocols are easily understood and followed, Legence provides safety materials in multiple languages.

ƒ Legence understands that one size does not fit all when it comes to PPE. Gender-specific protective harnesses are just one example of equipment that is designed to fit and protect men and women differently. Legence purchases and provides the right PPE for every individual while on the job.

DRIVING SAFETY POLICY

Many of our employees find themselves on the road as part of their daily work. The safety of our staff is of the utmost importance to us, which is why we have specialized driver safety training to reduce distracted driving, help acclimate our drivers to winter driving conditions, and relay safe driving practices.

CONSTRUCTION SAFETY WEEK

Every May we participate in Construction Safety Week to reaffirm our commitment to safety. Across Legence, special events are hosted with a focus on safety education. These events range from on-site and in-office training sessions, lunch and learn presentations, and equipment safety demonstrations where vendors are brought in to provide training on specific tools. Yearout Mechanical even brings their entire workforce together for a day long safety workshop. While the medium and methods may change across business units, the goal is the same—to ensure that our teams have the knowledge and skills they need to stay safe and protected on the job.

SAFETY ONSITE AT OUR FABRICATION FACILITIES

Our fabrication facilities are prime examples of our commitment to safety and efforts to spearhead Prevention through Design (PtD). The time and investments we supply to each facility help reduce risk and cut down on labor by improving efficiency and workflow. Each fabrication facility is designed as a controlled environment that allows us to develop and monitor our processes around best practices with the latest tools and technology at our fingertips. Our expert electrical service providers at VarcoMac have a newly designed facility that optimizes space for added efficiency. At Therma, we have a laser in our fabrication facility to cut sheet metal, and at Bel-Aire Mechanical, an automated pipe welder is in use. All of these tools and technologies reduce risks by lowering on-site labor and installation time.

WE ARE Positively Impacting the Environment

The built environment contributes 40% of all the carbon emissions on the planet, so the work we do within our business units makes an impact beyond the United States.

As an Energy Transition Accelerator™, we show up for our customers and provide end-to-end solutions that are improving building performance to positively impact our environment at speed and scale.

Our commitments, outlined below, are the markers of our success. As we grow and develop greater efficiencies throughout our operations, our goals and KPIs will adapt to ensure we are measuring and making progress on material aspects of our business.

OUR COMMITMENTS

ƒ Achieve Net Zero status across our corporate operational footprint by 2040

ƒ Achieve and maintain carbon neutrality annually, starting in 2024

ƒ Annually report our GHG emissions and progress towards Net Zero, with an interim goal to reduce operational emissions by 15% within three years of each acquisition

ƒ Develop a methodology to track and report on the avoided emissions from our market activities

ƒ Support and advise our clients on decarbonization and climate mitigation strategies

We are impacting the environment beyond our borders, helping decarbonize the world

Driving Towards Net Zero

In the same way we advise our clients to develop Net Zero strategies, Legence is developing interim targets for carbon emissions reduction in advance of our Net Zero by 2040 goal. This roadmap shows our progress to date as well as the initiatives we plan to explore in the future.

BENCHMARKING DATA

We are onboarding each facility into ENERGY STAR Portfolio Manager to benchmark data. To date, 100% of our facilities are benchmarked in ENERGY STAR Portfolio Manager, where we have the ability to track and manage our building data.4

INVENTORYING GHG EMISSIONS

Legence calculates a GHG inventory annually to benchmark and understand our sources of emissions. We use this information to get a full picture of our emissions sources and contributions so we can prioritize action and lay the groundwork to achieve net zero status by 2040.5

OPTIMIZING BUSINESS TRAVEL

In late 2022, Legence rolled out a centralized online travel booking platform called Onriva to help track and manage emissions from employee business travel. This platform allows for more precise tracking of our scope 3 emissions which are included in our GHG inventory, and helps identify instances to reduce unnecessary travel.

ACCOUNTING AVOIDED EMISSIONS

We have developed a methodology to quantify avoided emissions resulting from the delivery of Legence company services, and plan to launch that reporting initiative in 2023.

INTEGRATING BEST PRACTICES

We have crafted an ESG Program onboarding process to help new companies integrate Legence’s ESG program. The program includes guidance on tracking and reporting operations data for use in our annual GHG inventory and avoided emissions accounting, incorporating best practices, and driving efficiency and sustainability into operations.

CATALOGING FLEET OPTIMIZATION

We developed a strategy to transition to electrifying our fleet as vehicles and infrastructure become more widely available.

PRIORITIZING GREEN BUILDINGS

We strive to certify and maintain environmental certifications for company-owned facilities, in addition to partnering with landlords on leased properties to promote sustainable building performance, maintenance, and design.

CONSERVING WATER AND REDUCING WASTE

At our leased spaces we do our part to reduce water usage and minimize waste sent to landfills by conserving water and adopting recycling and reuse strategies.6 At our owned facilities, we use waterefficient fixtures and appliances, where possible, and implement waste management practices.

ASSESSING RENEWABLE ENERGY OPPORTUNITIES

We explore opportunities to participate in local community solar programs and, where possible, partner with landlords to explore the potential for onsite renewable energy generation. Two of our CMTA office buildings were designed with on-site solar, which is metered by the utility, providing distributed energy resources to the local grid. (See page 22)

INVESTIGATING RENEWABLE ENERGY PROJECT SPONSORSHIP

We are assessing the feasibility of off-site renewable energy sponsorships that can help us reach our carbon neutral and Net Zero goals.

PROCURING 100% RENEWABLE ENERGY

We have made incremental progress to purchase green power with a commitment to purchase 100% renewable energy for our operations. As a precursor to that commitment, we have conducted a cost analysis to identify the total investment needed to attain 100% green power and have begun discussing that strategy with our Board.

ƒ 1,344 MWh of green power purchased in 2022

ƒ $26,000 needed to purchase renewable energy credits to offset all scope 2 emissions from electricity 7

EVALUATING GREEN POWER

We plan to screen and select green power vendors in 2023 with whom we can develop a green power procurement strategy and accelerate green power procurement across all Legence facilities.

GROWING PARTNERSHIPS

We utilize renewable energy credits (RECs) as a last resort after exhausting all operational efficiencies and maximizing green power procurement. We will aim to partner with a trusted vendor of RECs and carbon offsets to offset any remaining emissions from our value chain to achieve carbon neutrality annually, starting in 2024.

SPONSORING RENEWABLE ENERGY

We have the potential to explore opportunities for direct sponsorship of renewable energy, carbon removal, or mitigation projects to take us the last mile on our road to Net Zero.

Prioritizing Green Buildings

When exploring options for our leased spaces, we look for sites that are transit-oriented, close to green space, and green building certified. We collaborate with our landlords to integrate green and high-performance building language into our leases in order to track and improve our environmental performance.

CMTA Zero Energy Office Spaces

CMTA designed and built two of their own zero energy office buildings to showcase engineering techniques for sustainable, energy-efficient building design.

CMTA designed and constructed their 20,000 square foot corporate headquarters in Louisville, Kentucky, to LEED Gold standards and received a perfect ENERGY STAR Score of 100 through strategic design efforts. Features like a roof-mounted solar photovoltaic array produce more energy than the building demands annually, making it Zero Energy. The building also achieved Carbon Neutrality in 2012 and uses geothermal heating and cooling. Beyond energy, daylighting and Aircuity Demand Control Ventilation are employed to increase comfort and provide a safe working environment for employees.

CMTA went beyond high-performance design at their Louisville, Kentucky, corporate office and engineered a building that also showcases health and wellness strategies. The two-story, 25,000 square foot building was designed and constructed to WELL® Gold standards. Special features like an approved alternative compliance path (AAP) for glare reduction saved costs and eliminated unnecessary shading to improve the quality of the space. LED lighting systems in the building use a color temperature designed to support circadian rhythm and reduce glare.

CMTA and Baltimore City Public Schools LEED

Platinum® Certified and Zero-Energy Building Design

Our engineers and project managers at CMTA are experts in green building design and construction.

In early 2021, two Baltimore City Public Schools (BCPS), Graceland Park – O’Donnell Heights Elementary/Middle School (Graceland) and Holabird Academy (Holabird), opened the doors of their zero-energy, zero operational carbon buildings to students and staff to finish out their school year. BCPS enlisted CMTA’s help in designing these buildings in 2015 to provide the school district an opportunity to re-imagine what energy efficiency and sustainable design could look like in their buildings.

Design of these buildings was completed in March of 2017 and focused on:

Achieved more than a 300% energy use intensity (EUI) improvement from average facilities

Avoided an additional 150.5 tons of carbon dioxide from the surrounding environment

Clean Energy

Clean energy is a key element of our emissions reduction strategy.

With the addition of the Inflation Reduction Act (IRA) renewables continue to become more cost-effective. At Legence, we are committed to procuring green energy for our entire organization. Utilizing clean energy will have a significant influence on moving the needle toward overall carbon reduction in our operations.

Electric Vehicles

The biggest producer of emissions throughout our business is our fleet of vehicles, and we are stepping up to identify a seamless integration of electric vehicles (EVs) into our operations where feasible. We conducted a fleet assessment with ICF to gain insights on our EV readiness. We will use that study to determine which vehicles we upgrade as EV production and infrastructure grows over the next few years. Recently, in preparation for this industry shift to EVs, we installed charging stations at two of our locations as an available amenity to employees who are early adopters of this technology, as well as to charge the few electric vehicles that are currently in use within our operations.

Black Bear Energy Renewable Energy Procurement

Each year the Solar Energy Industries Association (SEIA) releases the Solar Means Business Report to track solar adoption by America’s largest companies. Black Bear Energy, through competitive bidding and project management, helped Blackstone and its portfolio companies install close to 100MW of solar capacity, which is equivalent to the energy needed to power 16,400 U.S. homes.9 This robust renewable energy capacity led Blackstone to rank in the top 10 of corporate users by total installed on-site solar capacity and top five for the Real Estate Industry for total installed solar capacity in SEIA’s 2022 report. Black Bear’s project facilitation, collaborative client relationships, and best-practice oversight made this a reality and is a testament to their role in supporting the deployment of solar throughout the commercial and industrial real estate industry.

WE ARE Elevating Our People

A sustainable world needs big thinkers and that is exactly who our people are.

Legence’s legacy is defined by our people. We strive to diversify our workforce, and emphasize equity and inclusion for all. By bringing together and elevating our engineers, professionals, and craftspeople, we are able to provide them with more benefits and opportunities for both personal and professional growth.

OUR COMMITMENTS

Our power is our people

Our Benefits

We strive to offer exceptional benefits to our employees.

We have the advantage of a diverse makeup of companies in which to pull best practices from to bring the most comprehensive benefit coverage to our people. Merging benefits plans is not a simple process, but we are actively working to maximize and consolidate packages where we are able. We provide vision, life, and disability insurance at no cost to our employees on Legence benefits and have merged nearly all business units onto the same health care coverage plan.

Some of our business units employ team members who are represented by unions; these team members have prescribed coverage and benefits through their union providers, which Legence contributes to, but they are not eligible to participate in certain benefits. We are, however, making an effort to ensure unionized employees have access to auxiliary services like HealthAdvocate™ that go the extra mile to maximize a coverage plan’s potential.

Healthcare Difference Makers

As a legion of companies, our combined size has opened doors to more services and benefits partnerships:

HEALTH SAVINGS ACCOUNTS (HSA)

This benefit can help employees on a high-deductible medical plan save for expected and unexpected medical expenses throughout the year. Money is deducted straight from an employee’s paychecks, pre-tax, and deposited into a savings account that can be used to pay for eligible medical expenses, first-aid, and medications. Additionally, Legence provides an annual employer contribution of $1,200 for individual coverage and $2,400 for all other coverage levels.

SPRING HEALTH

A new program launched in January of 2023 which provides support and resources for mental health. Through this program each covered individual, including dependents, can access up to 12 free counseling sessions per person each year, along with selfguided resources and tools.

TWIN HEALTH

This program uses digital technology and medical science to reverse, improve, and prevent chronic metabolic diseases such as type II diabetes. The Twin Health program is helping team members normalize their blood sugar, reduce medications, manage weight, and feel better.

Financial Planning

Another benefit available to most Legence employees is assistance with retirement planning. We have partnered with ADP and Edelman Financial Engines to provide employees with financial education, resources, and planning tools. At the request of employees, we have improved our 401(k) plan to include investment in a sustainability-focused fund or the option to customize a personalized investment strategy through a self-directed brokerage account option with TD Ameritrade.

Diversity, Equity, and Inclusion

DEI remains a top priority in our company and our industry at large.

We are actively pursuing initiatives to identify more diverse candidates and have taken steps toward removing terminology and requirements that may exclude candidates from our job postings. By changing the narrative of our job postings to be more inclusive and skills-focused, we are widening our applicant pool. We appreciate the growth and opportunities that come as a result of bringing more diverse backgrounds and perspectives to our team and are proud of the groundwork we have laid to promote those outcomes.

Tracking Diversity

Through our applicant tracking system, Dayforce, we are able to collect, organize, and track candidate information including demographic and diversity data throughout the recruiting and hiring process. If hired, that information is carried over to Dayforce’s Human Resources Information System where we are able to produce a full picture of our workforce including age, race, gender, veteran, and disability status. Through the collection of this data, we will be able to target initiatives that grow diverse populations and accurately disclose the information about the individuals who make up Legence.

Training and Development

Compliance training, career development, and continued upskilling are all aspects we cover through employee learning initiatives.

Our aim is to build consistency across our legion of companies with basic training requirements at the Legence level on topics such as compliance and safety, while relying on our specialized subject matter experts to create a more robust learning platform through Legence U. We are dedicated to training our leadership on the principles of sustainability so they can disseminate that information to each of their respective business units, tailoring their delivery to each business unit’s ESG expertise.

Knowledge Collaboration: Building Science Leadership Group

The Building Science Leadership Group (BSL) at CMTA was established in 2020 and is comprised of building and engineering leaders from across disciplines who are focused on improving and maintaining CMTA’s collective building science expertise. With over 20 members from 13 different offices, the BSL Group hosts educational sessions and shares content on a dedicated BSL webpage which was recently launched in 2022. To date, the BSL has shared 40 articles and 50 training videos to the site. Moving forward, the BSL Group plans to launch a Legencewide newsletter to begin sharing knowledge across Legence’s business units.

Upskilling and Diversifying Our Workforce

When joining the Legence team, career development and success is pursued with emphasis. We want everyone helping us build better to know we are actively seeking resources to develop skills not only to serve our clients, but for the betterment and advancement of our industry. We have several resources at our disposal aimed at upskilling and elevating our people.

ƒ We work with Blackstone’s Career Pathways program to drive economic mobility for diverse and historically under-represented talent. This includes reframing our job postings to contain more inclusive language and removing unnecessary degree requirements that can become barriers to entry.

ƒ We use Direct Employers to place our open positions on sites that help grow talent from veteran and military sites, as well as disability and minority sites. Through Direct Employers, we are able to host our job openings on over 700 career sites to facilitate a large, diverse, and strategic talent pool.

ƒ We partner with unions, high schools, and colleges to provide hands-on apprenticeship, co-op, and internship opportunities. Through our work with Maryland’s Anne Arundel County School District and in partnership with the Architecture, Construction, and Engineering (ACE) Mentoring Program, we are teaching high school students the value of learning a trade. We currently provide 100+ active internships and 500+ union apprenticeships throughout our legion of companies.

ƒ We are developing a Legence-wide learning and development program, Legence U, with the help of seasoned leaders and experts in specialized roles. The aim of this program is to leverage our diverse knowledge, skills, and abilities available at Legence to support the growth and development of our team and broaden our collective knowledge.

We are CHALLENGERS

We are providers of new thinking and powerful solutions. We are ready to question convention and rethink what’s possible.

We are COLLABORATORS

We solve complex problems by working together as coworkers, clients, and partners.

We are DEDICATED

We’re committed to protecting our world and supporting the wellness of all people.

CASE STUDY

Therma’s Life-Saving Safety Training

The power and importance of safety training was recently demonstrated after two plumbing service technicians from Therma were faced with a real-life medical emergency. While on the job, Pablo Jimenez and Rigoberto Hernandez were unexpectedly thrust into action when a local delivery driver suffered a major heart attack. Pablo and Rigoberto relied on their CPR/AED training and saved the delivery driver’s life by performing CPR and calling 911. A representative from the delivery company expressed their gratitude for Pablo and Rigoberto’s quick response, and Legence could not be prouder of the selflessness and readiness displayed by Pablo and Rigoberto in this life-saving event. Their actions are a testament to our safety-first culture, and reinforce our commitment to providing safety training to all Legence employees.

Philanthropy and Volunteerism

Legence aims to practice good citizenship by fostering charitable giving, dedicating time to volunteering and community-building activities for our staff and stakeholders, and partnering with local non-profits and government programs to provide resources and support for causes that align with our mission and vision. Looking forward, we are setting up a process to track our giving and volunteer initiatives across all our business units to compile and share our impact on a year-over-year basis.

VOLUNTEER TIME OFF

Many of our business units provide employees with volunteer time off and host specific volunteer days to help make an impact within their local communities.

CASE STUDY

Sponsoring the U.S. Department of Energy’s Solar Decathlon

Legence is a steward-level sponsor of the U.S. Department of Energy Solar Decathlon and provided jurors from across our business units to act as judges for the event. With a mission similar to our own, the annual Solar Decathlon creates healthy competition between students to design and build high-performance, low-carbon buildings that mitigate climate change and improve our quality of life.

Freddy Boateng of RE Tech Advisors and Jess Farber of CMTA, were selected to participate in the Solar Decathlon as a juror and grand juror on the Build Challenge, respectively. Taking part in events like this is a rewarding part of our work that would not be possible without collaboration and communication between our business units and support from our Board. We are fortunate to be in a position to lend our services and financial support to this unique, skillbuilding event.

SPOTLIGHT

Gilbert and St. David’s

Before formalizing under Legence, many of our business units forged long-term relationships with community partners where they showcased good citizenship and made an impact in local communities. Gilbert’s professional relationship and corporate sponsorship of St. David’s Center for Child & Family Development Make Them Shine Gala is one such partnership. For the past 12 years, Gilbert has been a corporate sponsor and helped raise funds for this important cause that provides services and opportunities to children in need.

“Supporting students in the design of sustainable buildings is a clear demonstration of living our mission.”

Leadership Approach

Risk Management

Legence is dedicated to keeping up with industry trends and best practices in our approach to risk management. We believe that overall, our approach to risk should be levelheaded and realistic. We use outside resources such as insurers to help ameliorate some risks, but we also rely on our general counsels and information technology (IT) specialists to report on potential risks to the ELT, who will track, monitor, and respond to risks on a case-by-case basis.

Cybersecurity

Our cybersecurity efforts are based on the United States’ National Institute of Standards and Technology Cybersecurity Framework (NIST CSF) to keep people and their information safe. To assess our preparedness for cyber threats, we go through a range of scenarios including employee phishing exercises and table-top exercises to strategize our response to cyber-attacks. We continually respond and adapt to cyber risks to keep up with industry standards. As with all our policies, cybersecurity is reviewed annually, and we have dedicated resources and processes in place to communicate risks to leadership on a quarterly basis.

Supply Chain

Legence has a long line of suppliers within our various business units and through our supply chain practices we are able to support a variety of diverse business enterprises. These suppliers are often based on geographical locations and availability, and we frequently partner with small businesses who supply specialized parts and materials to our legion of companies. Through these intimate partnerships we are able to guarantee efficient, predictable service. As a bonus, our trusted suppliers heed this mutual relationship and provide us with essential market insights, such as rising demand on specific products or new materials slated for market.

Over 50% of our top suppliers are local businesses

To remain competitive in these markets we price check for fair rates. Foreseeable risks to our supply chain, including increased regulatory requirements, are something that we take seriously. We are doing our part to:

ƒ Actively choose fair and ethical sourcing

ƒ Price check and set fair rates of exchange

ƒ Reduce shipping emissions by sourcing from local suppliers where applicable

ƒ Procure sustainable Legence branded gear

Policies

Our policies hold us accountable for our actions and facilitate good governance. As a newly formed company with different procedures across our varied business units, our priority is to set forth the following policies for overall compliance. Each year we review our policies and make updates according to new risks or regulations. To date our policies cover:

ƒ Anti-corruption

ƒ Code of Business Conduct and Ethics

ƒ Delegation of Authority

ƒ Information Management

ƒ Travel and Expenses

ƒ Whistleblower Mechanisms

Whistleblower Policy and Employee Hotline

Our Whistleblower Policy details the procedure for employees or contractors to raise concerns without fear of dismissal or retaliation of any kind. Employees and contractors are able to use the avenues outlined in the policy to submit concerns regarding questionable accounting or auditing matters and other unlawful activity and may do so confidentially and anonymously. One such avenue is an employee hotline that can be used to report misconduct anonymously via telephone.

Committees and Councils

As we set up formal committees to help drive efficiencies and thought leadership across our legion of companies, we are finding a stride that encourages widespread participation.

Legence Leadership Council

The Legence Leadership Council (LLC) exists to foster collaboration and enhance communication among senior leaders throughout the enterprise. Its 125+ members make up a diverse body of leaders with representation from each of Legence’s business units and functions. The LLC meets at least once a month to disseminate critical information up and down the organization, share best practices and lessons learned, and provide a safe forum for members to provide feedback and satisfy their intellectual curiosity. Lastly, the LLC provides professional development to its more junior members from Legence’s most senior leaders.

Communications Council

Comprised of individuals from different business units, the communications council is tasked with ushering in a holistic communication process that works to provide helpful resources and guidance to our employees, as well as share happenings and success stories from our legion of companies.

Stakeholder Engagement

Stakeholder engagement is two-fold for Legence.

Our priority is our people, and we value the feedback and insights we gain from engaging with our employees. Beyond our offices and jobsites, we strive to engage with external organizations through industry events to be an active force for good and share our best practices.

Engagement Survey

Legence received over 800 responses on our first engagement survey that covered a range of topics from confidence in leadership and DEI-focused questions to safety in the workplace. With a 62% response rate, we were able to gain essential insights to gauge how satisfied our employees are.

Industry Participation

Our team is made up of big thinkers and industry veterans who are eager to share their experience and thought leadership to help advance our industry. By attending industry events and joining membership associations we are able to share our vision of a more sustainable future.

Transparency

We are committed to providing regular reporting to stakeholders on activities associated with our business in alignment with the United Nations Sustainable Development Goals (UNSDG) to drive transparency. It is in our best interest to align with reporting frameworks to showcase our commitment to transparency. Being transparent not only holds us accountable, but leaves room for collaboration and knowledge-sharing within our industry to help everyone transition faster to a more sustainable world. This annual sustainability report is the first step in our reporting journey, and we intend for it to grow and expand year over year.

UNSDG Alignment

The United Nations Sustainable Development Goals have been adopted by 193 countries and are the world’s shared plan to end extreme poverty, reduce inequality, and protect the planet by 2030. Through our ESG approach and initiatives, we align with 11 of the 17 goals:

NO POVERTY

Every member of the Legence team plays a key part in creating a more sustainable world, and we support our people by paying them competitive salaries and contributing to unions.

GOOD HEALTH AND WELL-BEING

We radically improve the performance of the built environment — making the spaces we occupy healthier and more sustainable. To support the wellness of our employees, partners, and professional communities, we commit to:

Maintaining a ‘safety-first’ culture, promoting the health and wellness of our team and an incidentfree workplace. We promote occupant health at our facilities through improved indoor air quality, access to daylight and natural ventilation, health and wellness amenities, and healthy building materials and furnishings.

QUALITY EDUCATION

We are upskilling our workforce for both technical and vocational positions to promote a well-rounded employee base and to grow our people’s skills for future career development and success. Through our business we also design and build certified green building education facilities to foster healthy, safe, and inclusive learning environments that benefit the communities in which we work.

GENDER EQUALITY

Legence maintains a diverse and experienced Board of Directors and executive team, targeting a minimum of one-third of members representing women and minority groups. We also conduct hiring practices that promote diverse hiring pools and will continue to be an equal opportunity employer. Our training and development is focused on upskilling our workforce and promoting diversity throughout our industry.

AFFORDABLE AND CLEAN ENERGY

Legence helps our clients innovate and expand their energy infrastructure to enable the adoption of alternative, renewable, and decentralized energy innovations. To date, Legence has helped design and implemented more than 150 MW of renewable energy generation.

DECENT WORK AND ECONOMIC GROWTH

Legence fosters a supply chain that drives economic growth for minority-owned businesses, and we have a successful history of acquiring and growing privately held and founder-owned businesses. We are growing our diverse employee base every year and are constantly evolving our practices to use industryleading tools and procedures that promote safety, efficiency, and innovation in our sector.

INDUSTRY, INNOVATION AND INFRASTRUCTURE

Our community engagement and technical expertise have generated over $5 billion in energy and infrastructure projects. Legence is a choice building science and engineering solutions provider. We pair sector expertise with creative ingenuity to lead and deliver design-build projects that meet efficiency goals and protect the wellbeing of occupants.

REDUCED INEQUALITIES

Legence provides career opportunities that are rewarding, respectful and embracing of diverse backgrounds and perspectives. We track, maintain, and report on diversity data. We also remain committed to increase hiring from veteran populations and other historically underrepresented groups.

SUSTAINABLE CITIES AND COMMUNITIES

As a national leader we play an active role in design and construction of the municipal, university, schools, and hospitals market, and in that role, we emphasize health and sustainability. Our approach improves operational and energy efficiency and creates high performance buildings while significantly reducing the amount of deferred maintenance. Through our efforts we have helped communities implement their carbon reduction roadmaps through performance contracting and both zero energy and zero carbon buildings.

CLIMATE ACTION

Legence is an Energy Transition Accelerator™. Our team radically improves the performance of the built environment by maximizing efficiency consumption. We have adopted climateconscious goals, policies, and processes and have embedded them across our organization.

PARTNERSHIPS FOR THE GOALS

Legence is a team of experienced solutions providers, working as one to push our clients further and build a future defined—and redefined—by efficiency. Our success is our clients’ success and is always the result of skill, dedication, and collaboration. To achieve our goals, we rely on every stakeholder. We engage our peers and partners to move the industry forward through advocacy and collaboration.

WE ARE Planning for the Future

While our business units have been providing decarbonization solutions for 50+ years in aggregate, we are still in the early days of Legence’s sustainability story.

This is both galvanizing and humbling. Our legion of companies—working in concert—have allowed our clients to define and accomplish their sustainability objectives at unparalleled speed and scale. At the same time, Legence has an opportunity to turn our expertise inward and push the envelope with respect to sustainability reporting and outcomes. To that end, we have endeavored to set an example in an area that remains largely uncharted—the tracking of avoided emissions—with a hope to inspire other firms to take similar, impact-driven action.

KEY ESG INITIATIVES FOR THE FUTURE

ƒ Maintaining a best-in-class safety culture for our employees, clients, and communities

ƒ Continuing to lead with respect to sustainability goal setting, tracking, and achievements

ƒ Remaining an employer of choice with limitless career development potential

ƒ Building upon our culture of philanthropy, community service, and volunteerism

The Legence vision is to build a sustainable future for all people. Everything we do makes a difference for our employees, our customers, our partners, our investors, and the planet. As set forth in this inaugural sustainability report, we are dedicated to continuing to invest in our people, culture, and processes to see these initiatives come to life. In tandem with our ESG programs, our core mission remains to be an indispensable, trusted advisor to the critical services providers operating in the built environment that have a meaningful impact on society, quality of life, and the environment.
