April 2021

2020 was an unprecedented year in so many ways. We worked hard, pivoted, and flexed to support our business, our stakeholders, and our colleagues. ESRT benefited from our more than a decade of groundbreaking, industry-leading work on healthy buildings, Indoor Environmental Quality (IEQ), and sustainability. We were in a position to focus on people, service, and the runway for our business. Our bold focus on Environmental, Social and Governance (ESG) matters continues. We have formally committed to achieve net-zero carbon emissions at the Empire State Building by 2030 and across our portfolio by 2035. We formalized and strengthened our commitments to Diversity, Equity, and Inclusion (DE&I) through the establishment of social impact goals and transparency in reporting key diversity metrics. We are a resilient organization that adapts and leads to deliver long-term value to our shareholders through excellence in our ESG performance. Sustainability, including energy efficiency, IEQ, and healthy buildings, is in our DNA and what we do every day. We use our experience and expertise to lead our business and engage with local, state, and federal government and inform our industry. Now we deliver our first Sustainability Report. We present the pathway to a confident return to the office in a post-COVID world. We are the first commercial office portfolio in Americas to achieve the WELL Health-Safety Rating, a third-party validation of our IEQ. We are now deep into version 2.0 of our work to bring more innovation in energy efficiency and IEQ. We will continue to deliver tangible emissions reductions, drive the industry forward, and report transparently on our efforts and milestones. Please read on and learn of our progress to date and plans for the future. We welcome the chance to share them with you. We recognize that DE&I is more than the policies and programs we implement. We strive to be an equitable employer and respect the unique needs and perspectives of all team members. Our leadership and embedded expertise have prepared us for unanticipated challenges, and our strong ESG foundation has become more important than ever. 2020 has underscored the benefits to our stakeholders of our long-term investments and unwavering commitment to sustainability.

EMPIRE STATE BUILDING: THE NATION ' S SUSTAINABILITY ICON

The Empire State Building, the World’s Most Famous Building, is the international icon of the New York City skyline. An urban campus within a single building, it is modernized and amenitized for the 21st century. The Empire State Building is also the leading international model for energy efficiency retrofits in the existing built environment. We have already reduced GHG emissions by 40% over the past decade. We now work on plans to reduce emissions by up to another 40% this decade. To achieve the deep energy retrofit at Empire State Building, we focused attention on the building’s envelope, mechanical systems, and lighting. The team started from the outside in recognition of the importance of improving performance through the building’s walls and windows. 40% Anticipated to reduce emissions by another 40% in the next decade. $4.4 million in annual energy savings.*

Reflective barriers were added behind each radiator to send steam heat back into the building.

*For more information, visit https://www.esbnyc.com/about/sustainability

20 EMPIRE STATE REALTY TRUST

REFLECTIVE BARRIERS Reflective barriers were added behind each steam radiator in the building, which allowed heat to better make its way into the building rather than being sent to the outside. WINDOW INSULATION The team then focused its attention on improving the building’s 6,514 windows’ resistance to heat and cold transfer through a comprehensive reconstruction performed in a window factory installed in the building. 96% of the original frames and glass was reused in the process that added a mylar sheet and a krypton/argon gas layer to the windows. ENERGY EFFICIENCY Once the building insulative envelope improvements were complete, the team installed technologies to improve energy efficiency inside the building. Automated LED lighting was installed to reduce the energy required to illuminate spaces. Tenants added plug load controls to reduce energy from devices left on during off hours. The building’s insulative envelope improvement allowed for the refurbishment, rather than replacement, of decades-old, existing chillers. The condensate from the building’s steam heating system is recycled to warm the water that flows out of taps. State-of-the-art energy-generating elevators transport the Empire State Building’s thousands of tenants. Regenerative braking was installed to capture the wasted energy from slowing down descending elevators and use it to power elevators going up. The Empire State Building is an employee attraction and retention tool for its tenants. Tenants pursue sustainability with their own high-performance certifications and participation in strategic energy and sustainability programs. The building’s custom Tenant Energy Management software allows all tenants to view and manage their energy use in real time.

The building’s 6,514 windows have insulating film with argon and krypton gas to prevent heat loss. Over 96% of the existing frames and glass was reused. The project achieved a 70% cost reduction compared to the cost of new windows. All work was performed on-site, translating to a 100% reduction in Scope 3 emissions* from construction.

*Energy and cost savings evaluated annually through the IPMVP Option D Measurement and Verification process.
