Sidara Chairman and CEO

Letter from Leadership

Introduction

For decades, our diverse collaborative of dreamers, darers, and doers has delivered projects that empower clients and communities around the world. And with our new brand, we have reaffirmed our mission to develop comprehensive solutions for the world’s most critical challenges, uniting under a shared purpose of advocating for the world as we would for our own home.

The following report showcases how we aligned our efforts around those key interventions of decarbonization and gender equity within the operations of our organizations and on the projects we touch. And while our formal reporting journey is just beginning, this report details how our companies have long upheld the principles of environmental stewardship, social impact, and good governance.

Advocating for Home

Strategic Growth

To align fully with that purpose, our Sustainability Council — with the direction and support of the Sidara Board — launched a company-wide journey to formally report on our environmental, social, and governance metrics. Our objective was to understand and quantify our impacts on the world we call home and identify the interventions needed to create the greatest positive impact possible.

For us, 2022 reflected a year of growth in our ability to deliver innovative and integrated solutions for our clients and across our entire portfolio of businesses.

Our research and exploration have led us to acknowledge that our companies operate in sectors that are carbon-intensive and traditionally male-dominated. The built environment remains one of the world’s greatest climate culprits. And as our global community focuses on achieving a low-carbon future, Sidara has committed to finding solutions that can facilitate and accelerate that transition. To achieve these objectives, our industry needs the creativity, expertise, and empathy of empowered women who can deliver inclusive solutions that uplift their communities.

About Sidara

ESG at a Glance

With the formation of Introba — the coming together of Integral Group and Ross & Baruzzini — we were able to not only transform the built environment by delivering living systems, but drive our ESG journey forward, resulting in the publishing of this very inaugural report. To enhance our service offering in environmental engineering, we acquired Greely & Hansen, allowing us to deliver specialty water services to communities in North America and beyond.

To support our company-wide energy transition strategy, Penspen launched its Energy Transition Consultancy, a multi-disciplinary center of expertise focused on the design, development, and repurposing of infrastructure to accelerate the global energy revolution and help nations reach net zero.

Finally, to further strengthen its credentials in regenerative and sustainable design, Perkins&Will acquired McLennan Design, an internationallyrenowned sustainability consultancy. Jason McLennan, the creator of the globally-recognized Living Building Challenge, now serves as Perkins&Will’s first Chief Sustainability Officer.

A Lasting Handprint Throughout this report, you will learn how our visionary clients continue to solve complex problems. From providing over one million people in Angola with solar power to increasing biodiversity via an apiary located at an airport, we are advancing the human experience, sustainability, and innovation with our projects around the world — the handprint we leave on society.

But this is only the beginning. Under the canopy of Sidara, we will continue to lead with imagination, commitment, and determination on our mission to create environments where humanity and nature harmoniously coexist, elevate how people live, connect communities, and make room for all cultures to shine.

Thank you for joining us on this journey, and welcome home. ​

ESG at a Glance Note from Sustainability Council Chair Our ESG Journey & Approach Goals & Performance Footprint vs. Handprint Our Commitments

Charlotte Douglas International Airport | Charlotte, North Carolina, USA - Landrum & Brown / Perkins&Will / TYLin

Note from our Sustainability Council Chair The world is undergoing the largest wave of urban growth in human history. Therefore, we must urgently incorporate decarbonization and sustainable practices into the space and infrastructure to accommodate the estimated five billion people who will inhabit those cities by 2030.

Recognizing that the built environment is responsible for producing nearly 40% of all global greenhouse gas (GHG) emissions each year presents us with a unique opportunity to innovate and introduce holistic lifecycle carbon planning and sustainable solutions that will bend the carbon curve and enable growth to proceed in a way that works for both people and the planet (WBCSD 2018).

Our commitment to ESG principles galvanizes the collective power of our people, inspires the communities we work with, and enables thriving built environments and ecological systems to regenerate rather than deplete.

The people and companies that make up Sidara share an exceptional vision for driving sustainability in all that we do. Through mechanisms such as our Sustainability Council and various global commitments, we have begun our formal ESG journey towards driving long-term change and the decarbonization of the built environment.

As the current Chair of Sidara’s Sustainability Council and a long-standing advocate and technical specialist for sustainable building practices, I am proud to lead a group that drives our vision forward on a practical, day-by-day basis. By bringing together sustainability experts and leads from across all our companies, the Council strives to achieve five main goals:

Note from Council Chair

Introduction

Our ESG Journey & Approach

ESG at a Glance

Our Planet

Goals & Performance

Our People

1. Support the identification and sharing of best practices across all Sidara companies.

2. Assist companies in operating new and existing buildings (within their direct control) that are net-zero whole life carbon by 2030.

3. Promote a low embodied carbon approach and net-zero carbon pathways in the work we deliver to clients.

4. Advance internal ESG efforts and build a culture of sustainability and stewardship across Sidara.

5. Collaborate with industry partners to advance thought leadership on sustainable infrastructure and policy.

If 2021 marked the start of our formal ESG reporting journey, 2022 was the year we established a baseline of our performance against indicators within the nine Global Reporting Initiative topics outlined in this report. Under the leadership of the Council, and guided by Sidara’s Executive Committee, we seek to establish a common framework for our ESG commitment across all our companies, which has been led by Introba and validated

by PricewaterhouseCoopers (PwC), as well as a common set of priority reporting topics for upcoming disclosures.

Reflecting on all the work we did in 2022, I am exceptionally inspired by our signatory onto the World Green Building Council Net Zero Commitment and subsequent research and advocacy in the“Beyond Buildings” report,

Footprint vs. Handprint

Our Governance

our presence and impact at COP27, and the expansion of sustainable projects within our existing portfolio.

Looking ahead, we aim to expand awareness and engagement across our companies, drawing on impact networks, a living systems worldview, and greater integration with natural ecosystems. We are also refining our approach to data management, emphasizing the collection of quality data, and strive to formalize the ESG expectations across Sidara.

As one of the world’s largest privately-owned architecture, engineering, and consulting groups, we see ourselves playing a critical leadership role in fostering a sustainable future for all of humanity. Our commitment to ESG principles galvanizes the collective power of our people, inspires the communities we work with, and enables thriving built environments and ecological systems to regenerate rather than deplete.

Strengthened by the diversity and expertise of our brands, we continue to strive for positive outcomes at scale. By combining the technical expertise, geographic presence, and unique culture of each company, we promise to deliver equitable sustainability solutions that focus on increasing resilience, resource efficiency, circularity, biodiversity, and whole lifecycle carbon to every client and project.

Our ESG Journey & Approach Rooted in a Regenerative Process The Purpose of our ESG Program is...

Our Design

– to galvanize the power of our people...

– in such a way that we catalyze, lead, and inspire within the communities where we work...

– to enable the thriving of ecological systems.

Working with the unique potential of Sidara, a collaborative of organizations whose exceptional expertise and diverse resources span all aspects of the built and natural environment, we seek to evolve our role from building on the environment to working with it. Specifically, we seek to play a key role in accelerating the transition to a lowcarbon future in which life is thriving.

Our Process To build a strong foundation upon which this program can develop and evolve, our work is based on the following premises: A. This is a capability-building process. Our program needs to evolve over time. Its ongoing viability relies on a shared commitment to learn through this process and co-create our approach.

B. Data is essential. The processes and systems to embed these outcomes will be supported with data collection to measure progress. This ensures that the program allows our business, our customers, and the communities we serve to thrive.

C. Third-party advice and review. In our inaugural year, we engaged a third-party consultant to provide a critical review of the program and advise on risks and gaps in preparation for official assurance next year.

Note from Council Chair

Introduction

Using ESG work as an instrument to realize that potential, our focus on Decarbonization and Gender Empowerment arises from the insight that these are nodal points of intersection for our industry, and ones which we can influence directly. Movement here will have impacts that ripple out to create other benefits to the larger social, economic and environmental systems in which our projects are located. This approach roots our program in regenerative practices by embracing a living systems mindset. The core principle we will use to guide the work is the stewardship of our Home.

ESG Impact Networks Through the conscious creation of ESG Impact Networks, we can accelerate change within the organization. Our approach is inspired by the Impact Network concept from David Ehrlichman.

Our ESG Journey & Approach ESG Reporting Structures Reporting Brands

Internally Operating via Pillars

All brands within Sidara are represented within the 2023 Collaborative Annual Report for financial performance in the 2022 fiscal year.

Sidara operates through five verticals, referred to internally as Pillars. Each Pillar includes a leading brand(s), as well as subsidiary or affiliate organizations, which we call our ‘specialty brands.’ To align with operations, this is collected through a Pillar approach. Each brand provides ESG data that is then rolled up and presented by Pillar and/or by region (where appropriate). ESG-focused initiatives (footprint stories) and project examples (handprint projects) will be highlighted in this report by brand.

As this is our inaugural year for ESG reporting, focus was placed on the leading brands to establish proper ESG Governance and programmatic structures.

The following brands were included in the ESG reporting for the 2022 fiscal year, and the graphic featured represents a static version of a dynamic evolution that continues to take place among our collaborative of brands: – Dar Al Handasah (referred to as Dar; specialty brands excluded in 2022) – Perkins&Will (specialty brands included in 2022) – Currie & Brown – Penspen – TYLin (specialty brands excluded in 2022) – Introba – Landrum & Brown (referred to as L&B)

Our ESG Journey & Approach Methods, Frameworks, and Assessments Methodology

Global Reporting Initiative

Risk & Materiality Assessments

The ESG program has been developed with guidance from our internal Introba team, including leaders and consultants from their Australian & U.S. ESG advisory services teams.

Introba’s remit was to take all brands within Sidara on this Journey, including collecting the data, facilitating stakeholder engagements and target setting workshops, as well as production of this report. The decision to leverage consultancy resources within was based on having the skills in our business and the knowledge of how to do this for large, complex and multi-regional organizations.

Details regarding our ESG methodologies can be found within the appendix.

The Global Reporting Initiative (GRI) was selected as appropriate on the basis that it is an internationally recognized framework which aligns with our global reach as a collaborative of companies. Additionally, GRI is the most holistic framework available; it allows us the flexibility to prioritize and select areas of focus within U.S., and it is compatible with other frameworks we are already using in various parts of Sidara, such as the WorldGBC’s Net Zero Carbon Buildings (NZCB) Commitment. GRI leaves us room to mature our ESG program over time, as best suited for our group of companies.

For the inaugural year of ESG reporting, our risk and materiality assessments were conducted in a series of workshops with our champions using the GRI’s complete list of topics as a structure.

See appendix for more details on our initial materiality assessment results.

This report has been reviewed by a third party (PwC) for feedback and verification readiness.

The review was conducted to validate our methodology, data collection quality, and governance process.

Note from Council Chair

Introduction

We intend to revisit the materiality assessment approximately every two to three years. In future years, we will require input from a larger group of stakeholders, and include a double-materiality assessment, in addition to expanding our use of metrics beyond the GRI framework.

We are targeting to submit for GRI reporting in 2024 based on the 2023 fiscal year. We will continue to track the fast-changing regulations and standards, with a plan to adjust our reporting program as necessary to meet market demand.

For target setting, we leveraged an outcomesbased approach, beginning with the collection of baseline performance data. With the results of the baseline data in mind, we identified a set of “Desired Outcomes” which will become our long-term goals (2040, 2050). Performance will be measured against short-medium term goals (2025, 2030) to evaluate our progress and hold us accountable along the way.

Collectively, our brands are well on their way to meet our 2025 targets.

Sidara’s ESG program has set clear baseline performance expectations (“good”) and a roadmap for raising the bar over time. The program has been designed to be agile enough to address the complexity and varied nature of the collaborative.

Governance

Each company can exhibit leadership (“better” or “best”) depending on where they are on their journey. Lessons learned through each company’s experiences can then be further utilized to support the advancement of others.

The creation of ESG Implementation Plans are scheduled for next year (2024), which will detail the actions needed to realize desired outcomes and identify all responsible parties.

Footprint vs. Handprint

Throughout this report, we refer to examples of footprint stories and showcase our handprint projects.

Our ESG program uses an “outcomes-based approach” structure. This identifies a desired end state, outlines how each desired outcome can be measured, and establishes a set of targets on a timeline against which our performance can be evaluated .

The desired outcomes serve as our long-term goals which we strive actively together to reach, while remaining aware of their inherent challenges and potential barriers that may be outside of our control. We have also set shortand mid-term targets to guide us along the way, contributing to a clear and aligned roadmap for all brands within the collaborative to follow.

“The World Green Building Council’s (WorldGBC) Net Zero Carbon Buildings Commitment is developed to recognise and promote advanced climate leadership action from businesses, organizations, cities and subnational governments in decarbonizing the built environment, to inspire others to take similar action and remove barriers to implementation.”

“The Women’s Empowerment Principles (WEPs) are a set of Principles offering guidance to business on how to advance gender equality and women’s empowerment in the workplace, marketplace and community. Established by UN Women and UN Global Compact, the WEPs are informed by international labor and human rights standards and grounded in the recognition that businesses have a stake in, and a responsibility for, gender equality and women’s empowerment.

WEPs are a primary vehicle for corporate delivery on gender equality dimensions of the 2030 agenda and United Nations Sustainable Development Goals (UN SDGs).”

“The United Nations (UN) Global Compact is a voluntary initiative based on CEO commitments to implement universal sustainability principles and to take steps to support UN goals. The world’s largest corporate sustainability initiative, the UN Global Compact is a call to companies to align strategies and operations with universal principles on human rights, labor, environment and anti-corruption, and take actions that advance societal goals. The multi-year strategy of the UN Global Compact is to drive business awareness and action in support of achieving the Sustainable Development Goals (SDGs) by 2030. The SDGs provide a powerful aspiration for improving our world — laying out where we collectively need to go and how to get there.”

C40 is a global network of nearly 100 mayors of the world’s leading cities that are united in action to confront the climate crisis. Mayors of C40 cities are committed to using an inclusive, science-based and collaborative approach to cut their fair share of emissions in half by 2030, help the world limit global heating to 1.5°C, and build healthy, equitable and resilient communities.

With endorsement from the Sidara CEO, Talal Shair, all Sidara’s leading companies will sign up to the WorldGBC Commitment. Those that have joined as signatories are: – – – –

Our Zero Carbon Commitment In line with the World Green Building Council (WGBC) Net Zero Carbon Buildings Commitment (the Commitment), we diligently monitor and evaluate greenhouse gas emissions (GHG) stemming from the buildings associated with our operational activities. In our 2022 data collection process, we meticulously gathered Scope 1 (direct) and Scope 2 (indirect) energy-related emissions data, categorized by office location (rolled up to the region) and operating company (rolled up to the Pillar).

Commit > Disclose > Act > Verify > Advocate The Commitment requires deep collaboration across the entire value chain, and radical transformation in the way buildings are designed, built, occupied, and deconstructed.

The Commitment considers the whole lifecycle impact of buildings and builds on WorldGBC’s Whole Life Carbon Vision and best practice principles for implementation.

1

Commit

Commit to operating all new and existing buildings within organizations’ direct control at net zero carbon, achieving maximum reductions of embodied carbon, and compensating any residual emissions in new developments and major renovations by 2030.

Support all companies within Sidara to achieve the same.

2

Disclose

Annually measure, assess, and disclose the Sidara portfolio’s energy consumption and carbon emissions, to include Scope 1 and 2. For any newly built asset or major renovation, Sidara will complete whole lifecycle analysis for embodied carbon reduction.

3

Act

Implement a decarbonization roadmap that outlines a reductionfirst approach, improving energy efficiency and securing renewable energy. Maximise the reduction of embodied carbon for any new developments or major renovations, compensating for all residual upfront embodied carbon emissions. Support Sidara in implementing energy conservation measures, procuring renewable energy and offsets, and procuring low-carbon materials for new assets or major refurbishments under direct operational and financial control.

4

Verify

Undertake independent third-party verification of energy performance and associated carbon emissions for assets and portfolios under direct financial and operational control. For the whole lifecycle, verify embodied carbon reduction to market baseline requirements upon building a new asset for own use or undertaking any major refurbishment to existing assets under direct control.

5

Advocate

Advocate in client engagements by promoting a low-embodied carbon approach and net zero carbon pathways; internally through efforts like Sidara’s Sustainability Council, and with industry partners by advancing thought leadership on sustainable infrastructure.

Learn more about: The Commitment - World Green Building Council (worldgbc.org)

For this inaugural year of reporting, we focused on the energy-related Scope 1 and 2 emissions. Some operating companies with more experience in greenhouse-gas-emissions reporting included additional environmental metrics, including water consumption and Scope 1 fleet vehicle emissions.

We’ve been tracking our operational emissions for the last decade and continue to make strides in carbon reduction. The Commitment helps hold us accountable to this goal.

For example, our recently enhanced decarbonization policy requires that, with every new office lease we sign, our places of business run on 100% electric energy, reducing dependence on fossil fuel energy sources. We aspire to be the change the building sector needs.

We are working to expand our collective reporting with aligned methodologies to include metrics on Scope 1 fleet vehicle and refrigerant (fugitive) emissions, water consumption, biodiversity impacts, and Scope 3 supply chain emissions.

We are aligning our data collection around GRI 302 Energy (EUI) and 305 Emissions. For 2022, the Scope 1 and 2 energy consumption (EUI) and associated GHG emissions for all companies within Sidara performed better than benchmarked data.

The energy-related GHG emissions performance compared to benchmarked data can be found in the table to right.

The results of our baseline year data collection led us to recognize an opportunity to consolidate our real estate holdings in certain regions to better align with the hybrid work model and make optimal use of underutilized office spaces. Additionally, we are actively engaged in ongoing lease negotiations with our landlords to phase out gas, install onsite renewables, and retrofit existing spaces with energy-efficient technologies.

Different regions also presented their own unique challenges for data collection. Looking ahead, we aspire to enhance our data collection processes to ensure more accurate and comprehensive performance data in the future.

Introduction to Our Environmental Impact

Introduction

We are recognizing the largest differences between benchmark and performance are those companies that have significant operations within the Middle East and Africa (Pillars: Dar, Energy). Our offices operating in Africa have an average EUI of 40 kBTU/SF compared to a typical office in the continent at 87 kBTU/SF. Within the Middle East, offices are fuel switching due to unreliable electric grids, where running on diesel generators are less carbon intensive than the electrical grids.

Sidara

Global Infrastructure

To address this challenge, we devised a data collection methodology which uses a “good/ better/best” framework to delineate the relative accuracy of data sets.

We recognize that employing benchmarking data introduces a margin of error, and we are actively pursuing strategies to secure access to more accurate data in the future. One strategic approach involves including a request for submetered data and utility bills for occupied floors as part of lease negotiations, both for existing and new offices.

Overall, in the 2022 Baseline year, Sidara’s total energy consumption (kBtu) was 15.8% lower than benchmarked buildings, and the total GHG emissions for Scope 1 and Scope 2 were 30.00% lower than the benchmark.

Energy

Introduction to our Benchmarking Solution

With over 92% of the offices (86% by area) that do not pay utility bills directly (outside of direct control), these offices are reported using EUI centered on benchmarking data (see benchmarking methodology) and measured against the typical performance of commercial offices in their specific regions.

Total Building Energy GHG Emissions (MTCO2e) - Comparison of Benchmarked vs. 2022 Performance by Pillar

Project Mangement

Per standard GHG protocols, we could defer such emissions to Scope 3 as it falls outside of our direct control. However, in anticipation of evolving technology, including the increased use of sub-meters by landlords and potential for new lease agreements, we are choosing to maintain all energy-related emissions of our operations within our Scope 1 and 2 reporting. This decision makes us better positioned to anticipate future emissions and plan strategically around decarbonization.

– Good = Benchmarking data leveraged where utility data is not available (traditionally Scope 3) – Better = Whole building metered data or utility bills which are prorated by leasable area (traditionally Scope 3) – Best = Actual energy usage from sub-metered readings or utility bills specific to leased/ owned space (Scope 1 and/or 2)

Embracing this approach not only grants us access to a greater volume of data but also enhances its quality. This is evidenced by instances where we have access to performance data, resulting in superior performance compared to benchmarked data as can be seen from the figure on the right.

Architecture

One of our main challenges is obtaining actual utility data for our leased assets. With 238 offices (sites) operating in 2022, in 60 countries around the world, over 96% of those offices are in leased spaces. In many of these leased spaces, utilities are often bundled within the overall rent, and in many of those cases the spaces are not submetered and/ or landlords do not provide whole building energy use data.

Our goal is to achieve “Best” data quality for all data points, but we understand that this process will take time, and will be critical when renegotiating lease agreements.

Innovative Benchmarking Methodology Benchmarking Methodology The need for building energy performance benchmarks in over 170 cities with Sidara offices has led to the development of a novel benchmarking methodology. This methodology aims to provide location-specific energy use intensity benchmarks while accounting for uncertainty in baseline parameters. It also offers a streamlined, scalable, and dynamic process that measures progress over time.

We have addressed this need by combining traditional energy modeling with machine learning techniques. This automated approach accelerates the creation of building energy models, enabling rapid evaluation of various design options. It not only establishes benchmarks in any country and city around the world, but also identifies high-priority carbon reduction strategies, offering a roadmap for future decarbonization.

models to provide scientifically-grounded targets and accommodate variations across a range of unknown factors.

effective decision-making frameworks that provide directionally accurate roadmaps toward designing and retrofitting low-carbon buildings.

The strength of our approach is in its ability to bring together building science and data science, or mechanistic models and machine learning (Design and Analytics). Our fully automated workflow rapidly, systematically, and intelligently completes end-use characterization, sensitivity analysis, parametric exploration, and multi-objective optimization to develop

Once a benchmarked energy use intensity (EUI) has been established for a typical office building within any given city or country, we combine these factors with local grid emission data to translate EUI into energy-related greenhouse gas emissions (Scope 1 and Scope 2). All these factors have been integrated into our new ESG Data Portal tool.

Probabilistic results are conveyed as distributions given uncertainties in underlying model inputs.

Handprint Project: Kingdom of Saudi Arabia Pavilion – Expo 2020 Dubai A complex challenge in high-performance design

Creating a sustainable and iconic “window-to-the-world” Inspired by the theme “the sky is the limit,” the Kingdom of Saudi Arabia’s iconic Pavilion soars in a symbolic, inspiring, and unique inclined prism design that draws on the Kingdom’s welcoming character and its rich history, with a nod to the Expo 2020 theme of “Connecting Minds, Creating the Future.” The design was envisioned to faithfully represent the Kingdom’s identity and tradition of hospitality, while taking millions of guests on an immersive journey to explore the country’s rich heritage, age-old traditions, vibrant culture, and natural wonders.

From the earliest stages of planning, the Pavilion was intended to meet highly ambitious sustainability and energy efficiency objectives. This commitment was inspired by the core values of the Kingdom’s Vision 2030 — sustainability, technology, and innovation — and by the high standard of sustainability set for Expo 2020 — which aimed to set a blueprint for sustainability and be one of the most sustainable Expos ever by ingraining sustainability in everything from the pavilions themselves and the construction process to the post-Expo legacy.

Dar’s detailed design for the LEED Platinum Pavilion incorporated everything from renewable energy and state-of-the-art energy efficiency features to water recycling schemes and construction materials with low-embodied carbon.

Saudi Arabia Pavilion, Expo 2020, Dubai, United Arab Emirates — Dar

Delivering results and inspiring business leaders, the Pavilion showcases how sensitive and ambitious design choices can create a complex and inspiring project with a highly impactful visitor experience.

By prioritizing the highest standards of sustainability and energy and water efficiency, we were able to achieve a staggering 82% reduction in indoor water use, and used 650 photovoltaic panels to achieve a 24% annual energy savings.

Handprint Project: LED Streetlights in Edinburgh Currie & Brown Wins “Energy Project of the Year - Public”

A greener, more welcoming city for future generations Edinburgh, United Kingdom — Currie & Brown

As part of one of its public service outreach events, Currie & Brown employees in Scotland partnered with team members at their client Amey to help upgrade more than 55,000 streetlights in Edinburgh to high-efficiency LED bulbs.

The project is predicted to save the City of Edinburgh Council around £54 million over a 20year period. It has already reduced total street lighting energy consumption by approximately 60%, while reducing CO2 emissions by 75% in the same period.

This contributed to the shared goal of the City of Edinburgh and Currie & Brown to create a carbon net zero city. This project was awarded the “Energy Project of the Year – Public“ at the 2022 Energy Awards.

In addition to the financial and environmental advantages of the project, communities across the Scottish capital have seen the benefits of this initiative. For example, upgrades to the lighting systems in the Colinton and Trinity Tunnels have allowed residents and visitors greater visibility and access.

This project delivered what it set out to: reducing street lighting energy consumption by approximately 60% [compared to the baseline year] and has seen CO2 reduced by 75%.

This translated to a cost reduction of £3.8m for the City Council by the end of March 2022. The project was also delivered under budget, with a strong safety record, and all amidst the backdrop of Brexit and a global pandemic. So winning this award was truly the icing on the cake.

Handprint Project: Biópio and Baia Farta Photovoltaic Plants in Angola One million solar panels for one million people

Revolutionizing Energy Access in Angola On July 20, 2022, Angolan President João Lorenço inaugurated the first two utility-scale solar photovoltaic plants in Benguela province.

A key enabler of Angola’s transition to renewable and clean energy, these transformational plants can collectively deliver up to 585 GWh of electric energy annually — saving over 214 million liters of diesel (which would have been required to generate this electric energy by diesel-powered plants) and consequently eliminating up to 723,000 tons of CO2 every year, reducing Angola’s greenhouse gas emissions and substantiating the country’s commitment to the Glasgow United Nations Climate Change Conference of November 2021.

The two plants are part of one of the largest public, renewable energy intervention programs in sub-Saharan Africa. The venture includes five other photovoltaic plants, which will deliver clean, sustainable energy to more than one million people in Angola.

Dar is providing consultancy services to facilitate the construction of these photovoltaic power plants, which will incorporate one million solar panels, designed to deliver 370 MW of clean, sustainable, and reliable energy.

Benguela, Angola — Dar

With one of Africa’s largest public renewable energy intervention programs, the Republic of Angola has taken a transformational and incredibly ambitious step in its energy transition towards cleaner and more sustainable energy. Dar is honored and privileged to be supporting the delivery of these seven photovoltaic plants which will save up to 723,000 tons of CO2 emissions every year, while providing reliable, sustainable energy for over a million people across Angola.

Handprint Project: EET Hydrogen’s low carbon hydrogen production plant in the UK Delivering a hydrogen economy in the UK’s industrial heartland.

Transforming the energy landscape to reach net zero As part of the UK’s commitment to net-zero (GHG) emissions by 2050 and goal to generate 70% of its electricity from renewable sources by 2030, Penspen, Sidara’s global energy specialist, is engineering the natural gas pipeline and related infrastructure required for EET Hydrogen’s large-scale, low-carbon hydrogen production plant — one of the first-of-its-kind in the world. In addition to supplying low-carbon energy for the country’s industrial heartland, EET Hydrogen’s new production hub will create low-carbon hydrogen to supplement electricity generation for transportation and to be blended into gas for heating. By 2030, its impact in reducing emissions will be equivalent to taking 1.1 million cars off the road.

to decarbonize through HyNet, UK’s leading industrial decarbonization project, including energy-intensive and high-process emission industries like cement and chemicals, as well as food and beverage production.

In its initial phases, the hub will produce 1.35GW of hydrogen capacity — more than enough to power a large UK city like Liverpool — and capture some 2.7 million tons of carbon per year.

By 2030, EET Hydrogen expects to deliver nearly 4GW of low-carbon hydrogen — 40% of the UK Government’s target.

This project will enable the decarbonization of hard-to- reach sectors including the heating of homes, fuel for industry, and flexible power generation. It will also create up to 75,000 jobs and generate £17Bn for the region and £37Bn for the UK.

Successful demonstrations at Pilkington Glass and Unilever have already shown how the switch over from natural gas to hydrogen could work and over 40 organizations have now signed up

Water Stewardship Although focus has been placed on decarbonization, we acknowledge that water stress is also becoming an issue in many places where we work globally, and we anticipate it to be an increasing point of climaterelated risk.

In 2022, some Pillar companies submitted data on water consumption, however, much like the barriers identifiied within energy and emissions reporting, since over 96% of our offices are leased assets, we do not have access to water utility bills or water meters for our operations. Therefore, we anticipate the need to rely on benchmarking until more data is made available by our landlords.

We are currently working on a methodology to benchmark our water consumption for our global portfolio.

Water Stress In preliminary climate-related risk assessments, we have been able to review countries which anticipate future water stress (ratio of total annual water withdrawals to total available annual renewable supply, accounting for upstream consumptive use).

Handprint Project: Google Bay View in California A “Net Positive Water” story in water-scarce California

Designing the largest LEED BD+C v4 NC Platinum-certifiied project in the world Mountain View, California, USA — Introba

Google’s new Bay View campus, located adjacent to the NASA Ames Research Center, is built to the highest design and sustainability standards.

Across the 42-acre site, there are 20 acres of open space, two office buildings, a 1,000-person event space, and 240 short-term employee accommodation units.

– Largest LEED BD+C v4 NC Platinum-certified project in the world and is expected to be the largest facility to attain the International Living Future Institute (ILFI) Living Building Challenge (LBC) Water Petal certification.

– 100% electric building in which even the kitchens are electric to decrease carbon emissions.

– Features a first-of-its-kind dragonscale solar roof across all three buildings, which uses the latest in building-integrated photovoltaic technology.

– Combined with power from nearby wind farms, Bay View will be one of Google’s first campuses expected to operate on 90% clean energy.

– Houses an innovative geothermal pile system to heat and cool the buildings, which is estimated to help reduce the water needed for cooling by about 90% compared with a traditional cooling tower system.

[This] has been a 10-year partnership — the largest, longestrunning project in our firm’s history. It epitomizes the growth we’ve experienced, not just in size but in capability, talent, and teamwork. As we like to say, the best ideas often come from the trades — and not just the engineers, but the pipefitters, sheet metal specialists, and those pulling wires.

Handprint Project: Chicago O’Hare International Airport Apiary A buzzworthy project located in unexpected infrastructure

Rebuilding urban biodiversity and social inclusion Since 2011 the Chicago Department of Aviation (CDA) has housed the United States’ first onsite apiary at O’Hare International Airport. As a long-time partner of the CDA, Landrum & Brown supported in the planning and implementation and is involved with ongoing tenant coordination.

This unique venture is part of a city-wide network of apiaries and is made up of 75 beehives which host over one million bees and produce more than 1,200 pounds of honey annually.

As bee populations have dramatically declined around the world over the last 20 years, so have yields of fruits and vegetables. Roughly 30% of all the food we eat is pollinated by bees, including 80% of all flowering crops in the U.S. each year. O’Hare’s on-airport apiary works towards replenishing bee populations, which in effect helps restore local ecosystems.

In addition to its environmental and biodiversity impacts, the apiary also plays an important social role. The honey produced here is processed and distributed as part of the Sweet Beginnings Beelove™ a social enterprise aimed at providing life-changing training and work experience to citizens returning from incarceration. The training and work experience allows graduates of the program to gain employment in many different industries such as manufacturing, food service,

Not only does this program respect the earth in the production of honey and its products, it provides important job opportunities for residents who are transitioning back into employment. Programs like this are critical to workforce development and to the health and vitality of our communities.

In fact, addressing refrigerant use globally is the number one thing we can do to mitigate global warming. However, refrigerant use is on the rise globally. We are witnessing a demand for air conditioning worldwide due to improving socioeconomic conditions in many countries, falling costs of equipment, air pollution and forest fire smoke preventing buildings from being naturally ventilated, the rising temperatures from climate change, and as we are seeing a shifting to electric heating systems that rely on refrigerants.

Research & Advocacy Handprint Projects: Future of Aviation

Research on the Future of Aviation has been Led by the Landrum & Brown and Dar Teams.

If you have ever traveled by plane, you have most likely visited an airport that Sidara has partnered with, worked on, or helped design. Throughout our history, we have planned, designed and constructed more than 300 airports across six continents, from large international hubs to specialized support facilities. In today’s post-pandemic world, however, it has become clear that we have entered a new era for airports, in which their design, construction, and operation must account for the growing impacts of climate change and the energy transition, emerging AI and technologies, and changing global demographics. Therefore, we believe the airports of the future will need to be designed to focus on the following:

Sustainability, energy & climate resilience

Passenger Experience

Innovation & Technology

The most successful airports in the future will be those that invest and innovate in these key areas. By bringing together our member firms to deliver the most complex and pressing projects, we continue to be the long-term partner of choice, ensuring that any airport, wherever it is needed in the world, can contribute to innovation and position itself as a hub of the future.

Research & Advocacy Representing Together at COP27

As part of our first-ever participation in the annual global climate change conference, we arrived at COP27 in Egypt’s Sharm El-Sheikh with an ambitious vision for the future: a unified, research-backed action plan that countries in the MENA region can follow to decarbonize three key sectors — the built environment, transportation, and water and energy resources. If implemented at scale, these recommendations would power a much more rapid transition to net zero in the region, while also improving the quality of life for communities and empowering governments to attract investments and talent.

COP27 Theme: Together for Implementation Dar sponsored and hosted a series of panel discussions, featuring experts from companies across the collaborative — including Penspen, Introba, Perkins&Will, and Currie & Brown — as well as industry leaders and influencers such as the World Green Building Council, PwC, WEF, and C40 Cities. Our workshops focused on net-zero solutions, the energy transition, decarbonization, sustainable and smart cities, and the circular economy. Dar’s experts also joined the World Green Building Council to launch the “Roof Over our Head” campaign, which aims to improve the lives of two billion climate-vulnerable people living in informal settlements. Throughout the conference, our teams also collaborated with the Egyptian Ministry of Social Solidarity, the Egypt Green Building Council, the World Economic Forum, the Marrakech Partnership for Global Climate Action, and other regional and international stakeholders to collectively explore and promote sustainability solutions. Within Sidara, COP27 sparked our collaborative’s widest internal employee campaign around sustainability principles and thought leadership to date.

The results of these explorations further Perkins&Will’s design work, improve processes, foster personal growth, and contribute to the knowledge base of our industry. Open to everyone at the firm, the program provides grant recipients 40 hours of company time, to be spent over six months, as well as $1,000 toward expenses (or 80 hours and $2,000 for teams).

A New Formula for Neighborhood Livability

Closing the Loop on the Circular Economy

What’s the Future of Transit in a SelfDriving-Car World?

The work recognizes a need for more comprehensive metrics to evaluate neighborhoods, expanding beyond traditional factors. The authors introduced “socialized” metrics, including rent burden and median home value, alongside conventional transit-oriented development metrics. This work showcased an increased awareness around equity and access issues and the need to expand the catalog of metrics used to define “good.”

Through ongoing conversations with manufacturer’s representatives focused on material health and embodied carbon, it became evident that take-back programs for materials such as carpet and ceiling tile were not apparent to project teams, leading to a gap in the circular economy. This project employed a series of surveys completed by building owners, general contractors, and product manufacturers to learn where these gaps are most apparent and how overlaps in approaches to lowering waste and embodied carbon can be leveraged in future design work.

This study, led by Nelson Nygaard, delves into transit best practices in the era of selfdriving cars. It recommends prioritizing transit to ease urban congestion and emphasizes the need to enhance the transit experience despite autonomous vehicle competition. Cost savings and reinvestment opportunities in autonomous transit are also highlighted. The project seeks to improve transit infrastructure and promote car-free travel.

Diversity, Equity, and Inclusion (DEI) We Are Up for the Challenge!

Desired Outcomes

Striving for equity within the workplace is a worthwhile challenge, as a diversity of voices at every table breeds innovation. The task of creating a workplace that fosters inclusion and a sense of belonging will be uniquely executed by each operating company, with each individual region working to address its own variety of complex challenges .

All companies within Sidara are dedicated to fostering and maintaining a workplace that is diverse, inclusive, and provides equitable opportunities for all. We strive to nurture a culture of respect and a sense of belonging across our companies globally.

“The world is our home. And for us, home isn’t just a place. It’s a feeling.”

The above sentiment is one we feel applies to each office in which we operate, and we desire to create a working environment in which all our people feel at home within their companies.

With a goal of achieving an aspirational target of gender equality within governance bodies, we acknowledge that this requires actively building a diverse pipeline of talent for the future. Therefore, we holistically prioritize ecology, equity, circularity, and resilience.

Achieving a goal as audacious as gender equality is contingent upon the advancement of opportunities for women within the industry at large. It will require a multi-faceted approach to meet our goals, which will include, at minimum, an active approach to academic STEM outreach to build a diverse workforce and pipeline of talent, as well as addressing any inequalities which may still exist within our operations today.

work to address female representation within the Middle East and Africa, as applicable to the context of the region. Additionally, we plan to expand our research to represent industry averages regionally (currently represents USA only).

– Gender Diversity by Job Classification – In alignment with broader research, female representation begins to decrease as one’s career advances. We will continue to address barriers to career advancement for women within operations in all regions and in all Pillars.

– Remuneration – The analysis on Gender Pay Equity Distribution has provided clarity on where gaps still exist within our operations.

The results in the remuneration graph on the following page communicate: – 100% means 1:1 male to female pay ratio (achieving gender pay equity) – >100% equates to where male employees are paid more than their female equivalent counterparts – <100% equates to female employees who are paid more than their male counterparts.

The results of this analysis has allowed us to pinpoint current gender-pay gaps, which are being elevated for evaluation and adjustment based on all pay equity factors including education, experience, and responsibilities.

Introduction

Employee Resource Groups (ERG) are voluntary, team member-led groups focused on fostering diversity, inclusion, and belonging within Introba.

These groups help team members build stronger internal and external connections; offer social, educational, and outreach activities; create development opportunities for future leaders; and increase engagement among team members.

ERGs are an excellent support system and vehicle for creating a culture of awareness and respect, as well as fostering diversity, inclusion and belonging within the workplace. ERGs are available to everyone currently employed or contracted with Introba. This means employees from all offices, functions, disciplines, and levels are allowed and encouraged to join, including those in management and leadership roles.

Since that first meeting on September 18th, 2018 (where Nat Oppenheimer, the Buildings Sector Leader at TYLin, was present with eight other industry professionals), DFF has grown to include over 200 industry professionals all pushing to eradicate human slavery in the built environment, both on the construction labor and supply chain sides of the equation.

Combining these principles with significant sustainability efforts within Introba, DFF has joined forces with countless organizations and teams to foster what we collectively refer to as Ethical Decarbonization — leveraging our combined efforts to better understand supply chains and realize new heights of knowledge and agency.

Diversity, Equity, and Inclusion (DEI) Handprint Project: Destination Crenshaw in Los Angeles

USA’s largest permanent outdoor art and cultural celebration of African American contributions

Fostering Culture and Community in the Heart of Black Los Angeles During planning of the LA Metro Rail extension connecting LAX to central LA, the decision to route the rail line at ground level on Crenshaw Boulevard could have impacted the Crenshaw community, the heart of Black LA. Instead, an opportunity emerged to foster the area’s strong arts culture. Anchored by permanent and rotating art installations, 10 new public parks, exhibits, and entirely new streetscapes, this 1.3-mile-long public art and cultural experience will run along Crenshaw Boulevard and celebrate the longstanding reputation of the neighborhood as a creative incubator as well as Black LA’s impact on popular culture and social change.

This outdoor culmination of sound, color, energy, and the arts will be the nation’s largest art and cultural celebration of African American contributions to world culture and was designed around the four themes of: improvisation, firsts, dreams, and togetherness. The project documents and preserves over 200 years of history of Black people in L.A. and will also present construction career opportunities for residents and is designed to support existing local businesses and provide artists from the area with a launchpad to start their careers.

Footprint Story: Learning & Development at Perkins&Will Exceptional L&D program at Perkins&Will

Employees and teams “Thrive” through internal programs that center around their growth and development “Thrive” is Perkins&Will’s internally designed performance management system.

It prioritizes a year-round dialogue between Champion and Partner, during which Partners (employees) work with one Champion to gather and understand 360 feedback, discuss career aspirations and set goals, and identify and complete development and training. At year’s end, we utilize a formal Review process to evaluate each Partner’s progress.

Our global Learning & Development efforts are focused on our organization’s strategy and our communities’ aspirations. By closing the gap between the opportunities of our future and our capabilities today, we can manifest our full potential. Through programs, tools, and partnerships, we deliver best in class solutions to get us from where we are to where we aspire to be. At the heart of everything we do is a belief that everyone can learn, and through this continuous practice, we demonstrate to this amazing industry what it is to be deliberately developmental.

Project Climbs: Great work results from a clear understanding of each project and the unique responsibilities, skills, goals, and work styles of each team member. While we have resources needed to help us plan and staff projects, we saw that more could be done to encourage strong communication, nurture feedback, and provide further development to project teams. Project Climbs is a critical mechanism to ensure teams are set up for success, prepared to make the necessary adjustments as they go, and willing to take the time to reflect and share important lessons learned to improve our work.

Footprint & Handprint Project: Our home at 150 Holborn in London Our “House of Brands” — all operating under one roof improves employee engagement, retention, and performance

Showcasing collaboration, co-location, and connectivity in the heart of London Designed and built by the companies that make up Sidara, 150 Holborn serves as an example of ingenuity as well as a purpose-built home to foster growth, creativity, and collaboration. With sustainability and data-driven performance improvements in mind, 150 Holborn has secured a BREEAM rating of Outstanding, has received an “innovator” design denotation by the Building Research Establishment, and earned a SmartScore rating of gold for its technologically advanced smart building features. It is also on target to achieve the highest building certification under LEED and makes significant contributions towards water and energy efficiency and materials use.

The 135,000-square-foot space encompasses eight floors that can house over 500 employees and includes a 2,500-square-foot landscaped rooftop pavilion/garden with 360 degree views of London. The concept evolved around a central atrium and an open staircase that runs the whole height of the building, linking easily from floor to floor and creating opportunities for chance encounters. This was conceived as the heart of the building and is characterized by transparency, connectivity, and openness.

Handprint Project: Student Residences at Princeton University 2023 AIA New York design award winner

Expanding learning opportunities for 1,000 university undergraduates in LEED Gold dorms New Jersey, USA — Silman

This expansion of Princeton University’s campus by adding two new residential dorms is intended to increase the university’s undergraduate population by up to 1,000 students. The project consists of eight mid-rise residential towers with connector buildings featuring extensive green roofs, as well as a central dining hall located partially below grade.

The framing system consists of structural steel frames with precast plank floors at the towers and structural steel with composite slabs on the metal deck of the central dining hall. The dining hall roof framing supports the “Campus Walk”, a system of sidewalks connecting each residential tower and interspersed with landscaping and seating areas. Most towers feature pass-through portals (where the Campus Walk cuts through the buildings), and large building-end cantilevers starting at the second level above grade.

The facade’s many finishes — including precast concrete panels, masonry, glass, and metal wall panels — all required careful detailing to support and integrate into the building. The project is currently on track to achieve its goal of LEED Gold certification.

Introduction to Social Impact

Introduction

This project was ambitious in creating collaborative student learning spaces within the dormitory buildings, with several common rooms, double-height meeting spaces, art studios, public art, and performance spaces intertwined with residential space. Multiple green roofs, including a structured plaza over the central dining hall, add to the aesthetic and are the most visible aspects of the LEED Gold certification Princeton is seeking.

Maintaining high standards of performance and continual improvement builds confidence in achieving our objectives and fosters optimism for the future. Sidara is committed to providing a safe and healthy working environment for all its people and stakeholders.

Sidara is committed to helping our companies become the best places to work, placing the utmost importance on the health and wellness of our employees. We engage all employees according to the nature and scale of their activities in achieving the goal of zero harm to people, property, and the environment.

Sidara has been reporting on Health, Safety & Environment (HSE) since 2020. During 2022, Sidara continued to refine and expand our performance reporting mechanism, widening participation to enable the global reporting of our HSE performance. The development of this reporting system has provided a basis from which to support our ESG goals and commitments. The HSE program has now expanded to become the ESG program, and the previous efforts are now reflected as OH&S, Employee Well-being, and Environmental Performance.

Our companies are dedicated to designing projects that not only minimize environmental impact, but also have a lasting positive influence on the health and wellbeing of the communities we serve .

Reporting on GRI 403 OH&S does not capture the full breadth of how we think about health, safety and well-being at Sidara. We are inspired by the WELL Building Standard from the International WELL Building Institute (IWBI), the JUST Label from the International Living Future Institute (ILFI), and other employee engagement ratings and surveys, including Gallup and Best Places to Work.

Health, Safety & Well-Being 2022 Performance

OH&S Training

Our overall 2022 safety performance continues to compare well with our market peers, and additional technical solutions have been developed and adopted by Sidara to further promote and improve engagement and reduce risk through the reporting of safety observations.

Maturity and development will benefit the investigation and reporting of incidents when they occur, and this will require further investment in the development of key personnel.

During 2022, Sidara increased its OH&S-related training hours by 260%, rising from 7,109 hours in the previous year to 18,663 hours. While this overall improvement is impressive, on aggregate it only represents a one hour increase per employee on average.

However, while we have established a solid foundation on which to develop, we must remain vigilant against complacency. To this end, we’ve adopted a structured approach, in alignment with international standards and best practices, to identify risk mitigation opportunities, support further improvement, and prioritize our focus and resources.

Currie & Brown (Project Management Pillar) continues to make good use of their e-learning services to provide desktop OH&S training, while Dar conducted a great deal of Fire Safety, HSEMS, Basic Induction and Refresher training for sitebased personnel.

Health, Safety & Well-Being 2022 Performance

The Total Recordable Injuries Rate (TRIR) is an internationally recognized OH&S metric, which measures annual injuries defined by the U.S. Occupational Safety and Health Administration (OSHA) as “any work-related injury or illness that results in death, loss of consciousness, days away from work, restricted work activity, transfer to another job, or medical treatment beyond first aid.”

Recordable Injuries by Class (2020-2022)

Total Recordable Incident Rates (TRIR)

0.9 0.8 0.7

The presented value indicates the number of recordable injuries within the organization for every 100 employees. The TRIRs are compared against the OSHA benchmark data for the Architecture, Engineering and Related Services industry, as a subset of the Professional and Business Services sector. To date, this value has yet to be revised from its 2020 figure.

0.6 0.5 0.4

The TRIR for 2020, 2021, and 2022 is provided in the table to the right, along with peer group comparisons. Although a lagging indicator, the TRIR is a direct measure of how effective our OH&S systems are at keeping our people safe. Favorable comparisons to the available benchmarks reflect well on those systems, however, this does not detract from our intention to continually improve our performance. We remain committed to driving our injury rates lower in the future and combining the TRIR metric with other leading indicators, such as training and near-miss reporting, as we journey towards our overall goal of zero harm.

Handprint Project: Thomas Jefferson Health in Philadelphia Strategy for the digital transformation of the hospital

A digital transformation for health care from the inside out Philadelphia, USA — Introba

By helping Thomas Jefferson Health in Philadelphia, USA, embark on a digital transformation, Introba is working to ensure the almost 200-year-old establishment continues to revolutionize the care it provides to patients by transforming its use of technology.

The central objective of the project was to provide operational guidance on a Joint Network Operations Center, which includes an operational model, physical design peer review, and financial model.

Introba conducted technology visioning workshops to identify the future capabilities needed and how they might be enabled by digital transformation. Patient experience technology use cases and integrations formed part of a comprehensive study to optimize workflows and process journeys in all clinical and administrative functions.

Digital transformation at TJH reduces the need for manual processes and physical paperwork and enables seamless data sharing, leading to a significant reduction in waste and a more sustainable approach to delivering patient-centric care. Additionally, energy monitoring and automated solutions can help minimize the carbon footprint associated with patient travel and hospital infrastructure, contributing to a greener and more eco-friendly healthcare system.

Health, Safety & Well-Being Handprint Project: Lululemon Store Support Center Hyper-focused on health and well-being

Walking the talk on wellness: a new headquarters office for Lululemon Vancouver, Canada — Introba

Lululemon is designing a new 13-story global headquarters in Vancouver, BC to reflect the company’s focus on fitness and an active, healthy lifestyle. Introba is collaborating with the company to align sustainability, health and well-being metrics with the company’s target audience via education, consulting, and documentation.

The building’s design will showcase how healthy spaces that promote occupant wellness also contribute to a more sustainable built environment. The design incorporates access to daylight, green spaces, and landscaped terraces throughout, as well as retail and restaurant space on the ground level.

Working with a client like Lululemon gave us the opportunity to think outside the box and we did so by leveraging an outcomes-based approach. Their understanding of well-being, tied to the roots of yoga philosophy, allowed for a creative approach, in a way that we never experienced on a project before. It required us to embrace biophilic design and a deeper understanding of how humans are innately connected to nature.

The project has ambitious targets for LEED Platinum, WELL Platinum and Zero Carbon certifications. In addition, Introba developed the overall approach for biophilic design and integration of healthy materials.

Health, Safety & Well-Being Handprint Project: The Point in Utah

600-acre site of publicly owned land to foster innovation and catalyze economic growth

Driving growth through mobility and walkability in Utah, USA Utah, United States — Sam Schwartz, a TYLin company

To help redevelop the 600-acres site of the former Utah State Prison, the Point of the Mountain State Land Authority hired Sam Schwartz to create a smart mobility plan for the “The Point”, designed to foster innovation, technological advancement, and catalyze economic growth in the youngest and fastest growing state in the country.

Once implemented, the plan will set a leading standard for the redevelopment of publicly owned land and can serve as an example for large-scale, mobility-centric developments around the world.

The Smart Mobility program includes five key elements: a dedicated transit circulator, an extensive, high-quality active transportation and micro-mobility network, electric car share, mobility hubs, and a mobility as a service (MaaS) program and app.

Although the site conditions and location for The Point are unique, the ideas can be replicated in other cities and inspire developers building multimodal communities or retrofitting neighborhoods to deliver a broad range of mobility options.

Introduction to Social Impact

Introduction

The Plan we developed demonstrates a completely new paradigm for urban development. The compact, walkable, urban design combined with a full vertical mobility system will achieve greater connections and enhanced community with a fraction of the greenhouse gas emissions compared with a traditional site plan. Our team created a template for sustainable mobility systems that can be replicated around the world.

Footprint Stories: Our Community Support Programs TYLin: Building Bridges in Our Community

Introba Gives The Introba Gives program is a global framework formalizing our commitment and approach to giving back to the communities in which we work and live.

Running from late September to early October, this year’s BUILDing Bridges in Our Community Week (BBC Week) included partnerships with a diverse range of organizations across the Americas, from Canada in the north to Panama in the south. With the aim of connecting TYLin’s people with local communities, this year’s effort involved nearly 300 volunteers from across the organization and included such activities as providing meals and medical aid, building structures, planting trees, and cleaning streets.

The program focuses on: – Supporting our communities and those most vulnerable through our time, skills and funds – Improving accessibility to charitable and humanitarian opportunities, platforming events, and supporting and supporting employees with flexible paid volunteer time – Introducing a financial process to support pro bono work by using our design skills to benefit non-for-profits – Creating more consistent and wider reaching impacts

In addition to building lasting relationships with local organizations, BBC Week serves to foster deeper connections between employees.

The annual event is managed by the BUILD Task Force, an employee-led group focused on deepening the firm’s understanding of diversity, equity, and inclusion, and was designed to advance TYLin’s vision to connect the people, places, and ideas needed to build smarter, more resilient, sustainable, inclusive, and equitable communities.

The Introba Gives program provides employees from all locations with four flexible volunteer hours to be used throughout the year.

Social Purpose Program at Perkins&Will The Social Purpose program gives Perkins&Will employees a chance to contribute to their communities in more personal ways, providing pro bono professional services to nonprofits to whom such services would otherwise be unavailable. Projects address human needs such as affordable housing, childcare, healthcare, and education. Whether it’s offering design or “sweat equity,” participants in the program are inspired by the power of human connection.

Perkins&Will published “Together, We Design: Stories of Giving Back Through Community Partnerships,” which showcases inspiring organizations that extend a hand to people in need — from children and teens experiencing homelessness to communities in areas at high risk for natural disasters. These organizations, and the people behind them, are everyday heroes: They see a problem and do everything in their power to help.

ResilientSEE Puerto Rico Water Filters Campaign from Perkins&Will

ResilientSEE Puerto Rico Earthquake Response from Perkins&Will

Following Hurricane Fiona’s impact on Puerto Rico in September 2022, the southern part of the island was left with 12 to 20 inches of flooding, destroying homes, roads, and bridges. In response, resilientSEE-PR, Bags of Love, and Círculo de Puerto Rico, three organizations dedicated to post-disaster recovery since Hurricane Maria in 2017, launched a fundraising campaign to provide water filters for three flood-stricken rural communities. With a $5,000 goal for 500 filters, resilientSEE successfully raised $2,700.

After powerful earthquakes hit Puerto Rico, Perkins&Will collaborated with local non-profits to design the Guánica Resilient Community Center & Emergency Center, a year-round community space. Equivalent to the size of two basketball courts, the Center will offer community support, such as a community kitchen and laundry, and legal and physicalmental services. It will also serve as a safe shelter during emergencies for residents and their pets. (More details on pp 43 of link)

TYLin, in collaboration with Bridges to Prosperity, constructed an inaugural hybrid suspension bridge over the Gasumo River at the Nyamagabe municipality in Rwanda. The seemingly straightforward design holds profound significance, offering passage for school children (even during rainy season), boosting the local economy, supporting local businesses, and enhancing healthcare accessibility, all aligning with Bridges to Prosperity’s mission of combating rural isolation to foster prosperity.

British Columbia, Canada — Introba

Introba has supported the new collaborative workspace and sustainability lab, Third Space Commons, led by the TQD team within the Faculty of Applied Sciences at the University of British Columbia, Canada. As part of its global Introba Gives Initiative, the team provides coaching and practical advice, benefitting communities worldwide through volunteering and pro bono projects.

Introba Gives also allows junior engineers, such as those at TQD, to take more ownership and responsibility on projects while leaning on the knowledge and expertise of their mentors whenever necessary . This latest project, which focused on the use of hempcrete, demonstrated how TQD’s design would result in 65% lower carbon emissions, which aligns with both companies’ missions to increase awareness around net-zero carbon and netzero design practices on campus, in the city, and beyond.

Very enjoyable and a privilege to work with the TQD team.

I was extremely impressed with their ideas, enthusiasm, and professionalism. Meeting tomorrow’s designers helps sharpen our focus within the industry.

Governance of Sustainability

Sidara maintains a well-established governance structure, comprised of a Board of Directors and five standing committees: Audit Committee, Leadership Development Committee, Investment Committee, Executive Committee, and Risk Committee.

Sidara recognizes that good corporate governance is not static and is committed to continually evolving to meet changing circumstances and requirements, and support growth and sustainability.

A commitment to sustainability is a longestablished part of our culture. Sidara was founded in 1956 by Dr Kamal Shair, a social entrepreneur with a desire to improve life for the people who lived and worked in Sidara’s environment.

This structure is designed to establish governance from the top down, with the Board and its Committees providing oversight and guidance to the Pillars.

Over the last 18 months, this structure has expanded to include the establishment of Sustainability, Digital, and Innovation Councils, which provide concentrated focus by professionals with the requisite knowledge and expertise.

Sidara is committed to rigorous governance across its organization, ensuring transparency and accountability.

The world in which Sidara operates is a changing landscape driven by technological advances and increasing demands for sustainability and social responsibility. 2023 marked the launch of a Board-driven governance project, led by our Executive Director Bashar Rihani, aimed at evolving and improving Sidara’s corporate governance to address these changes.

The project follows the corporate governance framework of the Wates Principles, focusing on: – – – – – –

Good governance is not just important for Sidara but for all the communities and societies where we work. Therefore, the sustainability features and positive, long-lasting impacts of our project are paramount.

“One of my key aims in founding a consultancy business was to establish an enterprise — a sustainable enterprise — that would go on providing jobs and creating wealth for the societies in which it operated for generations to come.” – Dr Kamal Shair Sidara continues, under the leadership and direction of its chairman Talal Shair, to build on its sustainability-focused foundation via its newly launched governance project and the formation of the Sidara Sustainability Council.

“As a leader, I aim to build a culture of greater collaboration and responsibility across our more than 300 offices and over 19,00 employees, while upholding Sidara’s commitments to sustainability, net zero and ESG.” – Talal Shair

ESG Methodology Risk & Materiality Assessment For the inaugural year of ESG reporting, the risk and materiality assessments were conducted in a series of workshops with the Pillar champions using the GRI’s complete list of topics as a structure. Each Pillar had to identify its “top 10” topics that were deemed material to their business. This helped us understand unique context, as well as uncover commonalities and divergences between operating companies.

We intend to revisit the materiality assessment approximately every two-three years, and in future years will require input from a larger group of stakeholders (both internal and external).

As part of the materiality discussion, Pillar champions were asked to rate the severity and likelihood (assuming existing mitigations are in place) of each topic and plot them on the chart(s) to the right. Risk was considered in terms of reputational, operational, and commercial.

Once the “top 10” were completed in the workshop, the ESG Champions were asked to undertake this process across the remainder of the topics. From the risk & materiality assessments, four topics emerged with strong support across all Pillars. Additional metrics were recommended to be included to align with the vision and goals and to support requirements of Sustainability Linked Loans (SLLs). Lastly, final metrics were included to our initial disclosures list based on data availability and program maturity.

ESG Methodology Data Collection

Environmental (E) Data

The Sidara ESG data collection process bridged across seven (8) central environmental metrics addressing the topics of energy, emissions, refrigerants, water, waste, business travel, employee commute and supply chain ; six (6) central Social metrics addressing the topics of diversity, remuneration, turnover, health & wellbeing, training, and community impacts; and six (6) Governance metrics addressing the topics of governing body diversity, policies, structures, economics, commitments, and risk. These topics originated with the Sidara ESG Champions and in reference to the World GBCI Commitment, the Global Reporting Indicators, and the Just label.

The Environmental data collection efforts for 2022 focused primarily upon the topics of energy and associated greenhouse gas (GHG) emissions from Scope 1 and Scope 2 sources. The other E metrics’ data was not readily available from all our operating companies, and so did not become an established output of this 2022 report.

The data collected was received in varied time periods across 2022 (annual, quarterly, monthly).

For this reason, the data collected for the year 2022 is calculated on a total (annual) basis, so that the ESG metric data provided by the different operating companies could be consistently represented for the full calendar year. This method, therefore, relied on the data available at the time of publication.

The use of such an outcomes-based approach allowed for us to stay accountable to our goals while identifying gaps and areas of opportunity for future years. The 2022 data will serve as a baseline for future years of Sidara data collection, except in instances where a more ambitious baseline is set by Sidara for a particular ESG metric(s).

Introduction

Energy consumption was reported by our operating companies, as well as office square footage, to allow for the final determination of each individual office’s Energy Use Intensity (EUI) and greenhouse gas emissions. This energy consumption data comes from utility bills provided to each individual office location Sidara relied upon the use of the U.S. Department of Energy’s EIA (Energy Information Administration) and AFDC (Alternative Fuels Data Center) for GHG emissions factors. These factors were used to calculate the GHG associated with energy and fuel consumption reported to us. The use of the AFDC’s data was necessary as Scope 1 energy consumption was reported not only in energy units (e.g., kWh) from the grid, but also in terms of diesel and/or natural gas consumption.

In some instances, operating companies did not have energy consumption data available.

For these particular cases, a ‘benchmarking’ approach was utilized. The benchmarking approach was the use of a model which

accounted for office size, location, and predetermined combinations of baseline building parameters (locations, program types, envelope constructions, usage profiles, conditioning systems, etc.) to output projected building energy consumption.

Social (S) Data The Social data collection efforts for 2022 addressed a large body of confidential information. For this reason, reporting from the operating companies was handled individually for each Social metric; particularly where it concerned the measurement of Diversity, Equity, and Inclusion (DEI) performance. The DEI data was therefore provided directly to the Sidara ESG team, and the data stored in a private location.

Occupational Health and Safety (OH&S) data was obtained through the Dar HSE Performance Report 2022 (prior to Sidara rebranding), led by Sidara’s Head of OHSE. Educational training data was collected through internal tracking and was provided to the team and stored in a private location.

Leadership demographics data was collected through internal tracking and then provided to the team and stored in a private location.

All other social data, namely remuneration and turnover data, were likewise provided only to the Sidara ESG team and stored in a private location

Governance (G) Data The Sidara Governance data exists as a conglomeration of diversity data (specific to governing bodies), and reporting on policies, commitments, economics, risks, governance structures. Additionally, data is collected with regards to anti-bribery & corruption training & education offerings. For the year 2022, this data was not available from all of the Sidara operating companies and as such limited data performance has been disclosed. ESG policies, including data collection methodologies are under development.

This report has been reviewed by a third-party for feedback and verification readiness by PwC. The review was conducted to validate our methodology, data collection quality, and governance process. This report is not assured.

Corporate employees, regionally allocated employees and remote employees were associated with the office which they are geographically assigned to for the purpose of analysis.

Greenhouse gas (GHG) emissions: Gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of thermal infrared radiation emitted by the Earth’s surface, the atmosphere itself, and by clouds.

This property causes the greenhouse effect. Water vapor (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4) and ozone (O3) are primary greenhouse gases in the Earth’s atmosphere.

Green power: Green power refers to energy generation sources that do not produce greenhouse gas emissions during their electricity generation operations and produce the least environmental impact among today’s offerings. Green power is purchased through the local municipality, typically at a premium rate. It should be noted that the actual electrons delivered to an asset (building) do not have a different carbon intensity than buildings which do not purchase green power. Purchasing green power financially supports more renewable energy being added to the local grid, and thereby helping to reduce the carbon intensity of the entire grid over time.

IGES Factors: Institute for Global Environmental Strategies are a publisher of a global list of grid emission factors. This list is used when a regional source cannot be found.

Indirect Emissions: Emissions that are a consequence of the activities within well-defined boundaries of, for instance, a region, an economic sector, a company or process, but which occur outside the specified boundaries of the activity.

Just Label: A voluntary disclosure tool administered by ILFI for organizations to help optimize policies that improve social equity and enhance employee engagement.

Key Performance Indicator (KPI): a measurable value that demonstrates how effectively a company is achieving key business objectives. Organizations use KPIs to evaluate their success at reaching targets.

Lesbian: A woman who is emotionally, romantically or sexually attracted to other women.

LGBTQIA+: Lesbian, Gay, Bisexual, Transgender, Queer and/or Questioning, Intersex, and Asexual and/or Ally Living Systems: Living systems are open self-organizing life forms that interact with their environment. These systems are maintained by flows of information, energy and matter. Multiple theories of living systems have been proposed. Such theories attempt to map general principles for how all living systems work.

NABERS Rating: the National Australian Built Environment Rating System, is an initiative by the government of Australia to measure and compare the environmental performance of Australian buildings and tenancies.

NGA Factors: National Greenhouse Accounts Factors are prepared by the Department of the Environment and Energy and is designed for use by companies and individuals to estimate greenhouse gas emissions.

Nodal: being, relating to, or located at or near a node.

Nodal decision making requires seeing or imaging the entire set of stakeholders at work with one another, expending the least effort to do what is most beneficial in order to return the system to self-direction or elevate it to a higher level of expression.

Introduction

Residual Emissions: Emissions which exist despite all feasible sustainability efforts to eliminate emissions.

Scope 1 Emissions: Direct greenhouse (GHG) emissions that occur from sources that are controlled or owned by an organization (e.g., emissions associated with fuel combustion in boilers, furnaces, vehicles).

Scope 2 Emissions: Indirect GHG emissions associated with the purchase of electricity, steam, heat, or cooling.

Although Scope 2 emissions physically occur at the facility where they are generated, they are accounted for in an organization’s GHG inventory because they are a result of the organization’s energy use.

Scope 3 Emissions: Indirect GHG emissions are the result of activities from assets not owned or controlled by the reporting organization, but that the organization indirectly affects in its value chain. Scope 3 emissions include all sources not within an organization’s Scope 1 and 2 boundary. The Scope 3 emissions for one organization are the Scope 1 and 2 emissions of another organization. Scope 3 emissions, also referred to as value chain emissions, often represent the majority of an organization’s total greenhouse gas (GHG) emissions.

SDGs: 17 Sustainable Development Goals (SDGs) are an urgent call for action by all countries - developed and developing - in a global partnership. They recognize that ending poverty and other deprivations must go hand-inhand with strategies that improve health and education, reduce inequality, and spur economic growth – all while tackling climate change and working to preserve our oceans and forests.

Underrepresented Groups: A group who are fewer in number than the statistical norm for their group in society, such as people who identify as women, LGBTQIA+, disabilities, veterans, and from underrepresented minority groups.

Underrepresented Minority Groups: persons who identify as Indigenous or as a racial or ethnic minority in their region (as per minorityrights.org) Water Use Intensity (WUI): The ratio of Water Use Intensity (WUI): The ratio of water consumption to floor space.

Wellness: An active process of becoming aware of and making choices toward a healthy and fulfilling life.

Wellness is more than being free from illness, it is a dynamic process of change and growth.

WEP: Women Empowerment Principles from UN Women WGBC: The World Green Building Council (World GBC) is a global network of Green Building Councils which is transforming the places we live, work, play, heal and learn.

Sustainability: A dynamic process that guarantees the persistence of natural and human systems in an equitable manner. Sustainability is a triple bottom line approach = People, Planet, Profit.
