In recent years, the world has undergone rapid and often unpredictable changes. Geopolitical tensions, economic uncertainties, and climate change are all challenges to which both companies and communities must respond. In this environment, it becomes particularly important to build on stable values that provide direction in the long term.

The story of Graphisoft Park has always been about being more than just an office or business park. We are building a community where innovation, collaboration, and a human-scale environment coexist. As CEO, my top priority is to preserve this unique atmosphere while ensuring that the Park remains at the forefront of international sustainability.

I am convinced that sustainability is no longer merely a responsibility, but also a competitive advantage. Our goal is to align our operations and developments with the highest international standards and to obtain and maintain certifications that authentically reflect our commitment to environmental and social responsibility. At the same time, for us, sustainability is not solely about metrics and reports: the quality of our daily decisions, the harmony of the built environment, and the well-being of our community are just as important.

In the future, we will therefore strive for developments and operational solutions that simultaneously strengthen our environmental performance, support our tenants' success, and further enrich community life of the Park. We believe that a sustainable business environment is truly valuable only if it is not only efficient but also inspiring and people oriented.

While ESG regulations and expectations are constantly changing worldwide, the most important guiding principle for Graphisoft Park remains the responsible mindset that has defined our operations since the Park's founding.

I would like to thank all our colleagues, partners, and tenants for their dedication to ensuring that Graphisoft Park is not only a successful business environment but also a sustainable and livable community. I am convinced that together we can further strengthen this unique place and set an example of how economic success and responsible operations can be mutually reinforcing values.

Overview of Our Company Group

Graphisoft Park SE is a listed company exclusively focused on real estate development and management. The Company was established on August 21, 2006, through a de-merger from Graphisoft SE European Joint Stock Company, a globally recognized software developer. The company's shares have been listed on the Budapest Stock Exchange (BÉT) since August 28, 2006. Since January 1, 2018, Graphisoft Park SE has been operating as a Regulated Real Estate Investment Company (SzIT).

The total land area owned by the company today, after the sale of the Southern development area in July, 2025, is approximately 16 hectares, located in Budapest's 3rd district, directly on the Danube riverbank, on the former site of the Óbuda Gasworks (town gas manufacturing plant). Over the past 25 years, a total of 82,000 square meters of leasable space (office, laboratory, educational, and other related service function buildings) was developed and put into operation on this site. Approximately 2,000 underground related parking

spaces are available to tenants. In addition, there is the potential for further development of approximately 46,000 square meters of leasable space in other parts of the area, along with associated underground garages and service units.

Regarding the corporate group, real estate development activities are carried out by the project companies of Graphisoft Park SE (its subsidiaries), namely Graphisoft Park Ingatlanfejlesztő Kft. and Graphisoft Park South I. Kft., after the sale of Graphisoft Park South II. Development Kft. during 2025. Graphisoft Park Services Kft. is responsible for the operation of the Park, while Graphisoft Park Engineering & Management Kft. handles engineering and administrative activities related to the Group's real estate development and operations.

This sustainability report applies to Graphisoft Park SE and its subsidiaries, i.e., the entire Company Group.

Integrated real estate development, property, and facility management

Graphisoft Park is an integrated real estate development, property management and operating company, which is able to meet the needs of its customers and tenants in a complex manner by keeping these functions in one hand. We perform all of this in line with maintaining and further developing the Park's ecosystem and well-being services. We manage our buildings throughout their entire life cycle, including construction, utilization, operation, and renovation periods.

During all of this, we keep in mind the criteria that require the minimization of emissions and the environmental burden of a sustainable

built environment. Pursuant to the Company's general, conservative development policy, development of a new building begins only if there is significant demand from tenants.

Graphisoft Park today - real estate portfolio, tenant base, utilization

The Park is home of internationally recognized technology, research and development companies and educational institutions, creating the domestic "micro-Silicon Valley" dreamed of at the start of the development. The 20 buildings of Graphisoft Park provide space for more than 100 companies, from start-ups to multinational companies, where a total of more than 5,000 highly qualified employees work and about 1,000 students study. In addition to the Park's unique natural features, the technological and IT focus created the milieu in which such globally listed companies are present in the Park as tenants for a long time, such as SAP (since 2005), Microsoft (since 1998), Servier (2007 since), and of course Graphisoft SE, the software company that founded the Park but now operates as an independent tenant, since 1998.

The Aquincum Institute of Technology (AIT-Bud-apest) was located here in order to integrate the research and development work with the educational function, which became known at the best American universities through the teaching of one of Budapest University of Tech-nology's specialties. The International Business School (IBS), founded in 1991, which provided training in English from the beginning, and the Real School educational institution, which focuses on environmentally conscious education from kindergarten to graduation, also moved to the Park.

The effectiveness of the strategy is also confirmed by the fact that the Company operates its buildings at a permanently high, nearly 100% occupancy rate, despite the recent uncertain economic environment and changes to office use which have caused an observable decrease in demand on the office market.

The integration of the home office option and the flexible design of existing office spaces came to the fore among tenants. Among our tenants, we see that research and development work with a high degree of creativity and intensive collaboration cannot be without personal presence at least partially,

but the flexible use of communal spaces, meeting rooms and hybrid working overall reduces the size of the required rental properties. The effect of the trend is also reflected in the utilization of Graphisoft Park:

The occupancy rate in 2025 was 96%, an increase of 2% compared to last year. Similar to previous years, the occupancy rate of our offices is still exceptionally high compared to the Budapest average. This is also helped by the fact that the

tenants of Graphisoft Park commit to a longer period compared to the domestic average, due to the Park's unique natural features, the environment provided by the technological and IT focus, and the possibility of flexible office design. Since the opening of the Park in 1998, our tenants have spent an average of more than 16 years with us.

Building concept

In developing Graphisoft Park we planned for a low building density of 25%, with a height limit of 11 meters for new buildings. Colleagues working in offices built in this way feel comfortable in their workplace. The 550-meter-long, car-free Danube promenade adjacent to the park also contributes to the well-being of tenants and visitors.

As a result of conscious design, all our building's

One of the main considerations in the planning was the low density of buildings, which has resulted in a high proportion of green spaces (over 60%). Only 45,000 m2 of the total 160,000 m2 of buildable area is occupied by structures and buildings in the Graphisoft Park.

This means that the current land usage by buildings is a low

quality fresh air to flow into our buildings.

In addition to the new office buildings, the Aquincum Campus was created in 2013 with the renovation of the more than 100-year-old former Gasworks complex. Once renovated, the design and internal layout of the buildings made them suitable for educational purposes. Renovating old existing structures instead of erecting new ones is also environmentally beneficial, as it significantly decreases the amounts of materials and energy needed.

The typical building height is 3 floors, thus the height of more mature trees is dominating over the buildings. All buildings have high exposure to natural sunlight, which in the hot season is compensated for by natural shading provided by tall trees. The predominance of green surfaces is enhanced by the fact that most of the parking is provided underground. The Park is accessible to pedestrians, from the Angel Sanz Briz road and adjacent public spaces, as well as from the Danube bank. The 7-hectare green park is also open to visitors to the public.

Financial stability

In recent years, we have had to face more unexpected events than usual, just think of the outbreak of the Ukrainian-Russian war, the drastic increase in energy prices, or the high inflation environment. However, our company's revenues have not declined during this time, and operating cash flow has only been affected to a lesser extent. This is largely due to the fact that the office park's tenants are typically stable companies working in research and development and innovative solutions, which have not been affected so sensitively by the crisis. The rise of home office

and the spread of hybrid office use have had a smaller impact on occupancy compared to the Budapest average.

Based on the results of the last 5 years, we can say that stable operation providing

a secure cash flow strengthens investor confidence and cre-

ates value for shareholders.

Materiality analysis

Materiality analysis sets the foundation for our sustainability strategy, ensuring that we focus our resources and attention on our most important impacts. For the 2024 report, we used the materiality analysis carried out in the first half of 2023, as there were no changes in the business that would justify a change in the materiality analysis - this was reviewed and confirmed by the com-pany's management. Going forward, we will con-

tinue to monitor material topics, and if significant changes occur in the value chain or the market, we will review the analysis with the involvement of experts. In addition, we will actively follow developments in the double materiality methodology and changes in new reporting requirements.

1. Impact Analysis:

   During the impact analysis, we identified and prioritized the environmental, social, and governance topics that Graphisoft Park and our value chain have a direct or indirect impact on, or potentially could have. The analysis considered industry trends, obligations, expectations, as well as the goals, values, and management approach of Graphisoft Park.

2. Stakeholder analysis:

   Numerous stakeholders participate in our value chain and business operations, and their opinions and expectations are also crucial elements of our sustainability strategy. Using the results of the impact analysis, we developed a survey to assess stakeholders' opinions, which was voluntary and anonymous. As the first step of the stakeholder analysis, we identified and categorized our stakeholders.

   Since most of our buildings function as rental spaces, our key stakeholders are our tenants, as well as their employees and partners. Suppliers involved in the construction, maintenance, and operation of the buildings, as well as our employees who collaborate in these processes, are also crucial stakeholders in the value chain. As a public company, shareholders, investors, creditors, authorities, and other stock market stakeholders are also important interested parties.

   We strive to reach all stakeholders through various channels, including direct contact, (at least) annual tenant forums for our tenants, and continuous active communication with our shareholders and investors through announcements, publications, and general meetings. We regularly seek collaboration opportunities with local communities, our neighbors, and local governments.

   Our main stakeholder groups include:

   
   
   

3. Determining materiality:

Based on the evaluation of the stakeholder survey, the opinions of stakeholders, and the extent of Graphisoft Park SE's environmental and social impacts, we organized these into a matrix. Then, a group of internal and external experts determined the generally material topics, as well as areas of particular significance for individual key stakeholder groups.

As a result of the analysis process, the material topics identified were:

1. Energy efficiency

2. Material use

3. Workplace occupational health and safety

4. Well-being of employees and tenants

5. Climate risks

6. A stable tenant base

7. Long-term supplier cooperation

8. Fair and legal employment

9. Competitive salary and benefits

10. Ethical and legal business conduct

    Themes 11 to 19 were not initially included in the analysis of material topics but being of importance to us, they ended up being included. We also report on these topics in detail in our Sustainability Report:

11. Biodiversity

12. Water use

13. Air pollutants and greenhouse gasses

14. Waste generation

15. Renewable energy sources

SUSTAINABILITY REPORT

2025

Description of our sustainability strategy

Our Sustainability Strategy was updated and revised in the second half of 2025, in line with the following key principles.

Graphisoft Park's ESG strategy is based on the understanding that sustainability today is no longer merely an operational or compliance task, but a key factor in long-term competitiveness, investment value, and value creation. Accordingly, the Park addresses environmental, social, and corporate governance aspects through a unified, integrated ESG approach. In developing this strategy, special attention is given to the Park's natural features, its role in the community, and the technological and innovation-oriented nature of its tenant base.

Graphisoft Park aims to implement a sustainable business and operational model that meets the expectations of tenants, investors, employees,

and regulators alike, while preserving the human-scale, green, and innovative environment that forms the foundation of the Park's identity.

Environmental decarbonization, efficiency, and preservation of natural values

The central elements of the environmental pillar are decarbonization and the gradual implementation of energy-efficient operations. The Park aims to optimize energy consumption by modernizing building operations, implementing smart building management systems, and expanding digital consumption monitoring. The strategy places a strong emphasis on integrating renewable energy sources and reducing long-term dependence on fossil fuels.

The principles of circular economy are reflected in both operations and renovations, particularly through the minimization and reuse of waste generated from building operations and tenant fit-out work. An important element of the Park's environmental strategy is maintaining a high proportion of green space, protecting biodiversity, and strengthening urban ecosystems, for example through the use of green roofs, nature-based planting, and water retention solutions.

International green certifications-such as LEED, BREEAM, WELL, and GRESB-serve not only as credentials but also hold strategic importance for continuous improvement, market positioning, and tenant decision-making.

Society: tenant experience, community, and well-being

Our social pillar focuses on people: the Park's tenants, employees, and the broader community. Graphisoft Park is committed to providing a healthy, inspiring, and safe work environment that supports physical and mental well-being. This includes the quality of the indoor environment, natural light, air quality, ergonomic workspaces, and noise reduction.

The strategy also takes into account the transformation of work: community spaces and services adapted to flexible, hybrid work contribute to tenant satisfaction and the attraction of talent. Community building plays a key role through regular tenant programs, events, and collaborative initiatives based on dialogue, which strengthen long-term ties to the Park.

Diversity, inclusion, and accessibility are reflected in both the physical environment and the design of services. The Park aims to maintain an inclus-

ive environment that ensures equal access and a safe environment for all users

Corporate governance: transparency, compliance, and responsible decision-making

The corporate governance pillar forms the stable foundation of the ESG strategy. Graphisoft Park treats transparency and structured reporting as strategic tools, with particular emphasis on reporting in accordance with standards, as well as the expectations of investors and financiers. Digital sustainability data collection and monitoring create opportunities for enhanced information provision to tenants and investors.

Strategic situation assessment and ambition

The strategy is based on an internal and external situation assessment that identifies Graphisoft Park's strengths, areas for improvement, and environmental and market risks. Due to the constant evolution of ESG expectations, the Park aims to define its level of ambition by taking into account the entire operational and market environment.

Building on existing best practices, Graphisoft Park intends to gradually advance to higher levels of sustainability, thereby strengthening its ESG performance.

The ESG strategy is thus an integral part of the Park's business operations and developments, contributing to long-term value preservation and the maintenance of competitiveness.

buildings all demonstrate our commitment to the environment. For many years, we have been working to make our daily operations as efficient as possible, with increasingly reduced environmental impacts.

The built environment is responsible for significant emissions related to both development and building operations. Due to our company's operations (mainly due to raw material and energy use), our own climate impact and emissions across the value chain are substantial. In the development of the Park, the buildings are always equipped with the most modern, energy-efficient devices available at the time, aiming for long-term aspects of building operation and maintenance. Our goal is to further strengthen and continuously improve this approach, thereby redu-

Starting from 2023, our renovation and modernization programs will focus on projects that increase energy efficiency and optimize energy consumption, which we implement in continuous consultation and collaboration with our tenants. In line with our objectives, between 2023 and 2025, solar panel systems, new windows and doors, and heat pumps were installed in certain buildings, tailored to the specific needs and decarbonization goals of the respective tenants. In 2025, as part of our long-term ESG strategy, we also began developing a comprehensive energy modernization roadmap, based on which we will launch energy efficiency improvements in 2026-2027 on several larger buildings

The mechanical setup of the buildings varies; some are equipped with traditional gas boilers and refrigeration units, while others use VRV systems. The mechanical ventilation includes heat recovery units. Lighting in many areas is controlled by motion sensors, and LED lighting has been installed in the garages. We have also continued to implement LED lighting in common areas.

Sustainability of Our Buildings:

Green Building Certification

Guided by BREEAM standards and striving for carbon neutrality, we manage and renovate existing buildings and plan potential future new investments.

In 2017, Building 'N' was developed according to BREEAM New Construction standards. From the preliminary design stage, a BREEAM AP qualified professional was involved, supporting and guiding the entire building development process. Adhering strictly to BREEAM's rigorous criteria, the character of Building 'N' was formed with the involvement of external stakeholders, placing

great emphasis on complying with the norms of sustainable built environments, catering to tenant needs and well-being.

Building 'N' in the Park, based on its certification, features numerous amenities and wellness functions that cater to tenant needs. This includes the development of proper combinations of lighting systems and natural light with shading; ensuring good air and water quality; maintaining optimal noise levels within the office area and providing adequate sound insulation; ensuring alternative ways to access the building; placing electric car chargers in the parking area; and actively contributing to the fit-out of tenant spaces.

SUSTAINABILITY REPORT

2025

Building 'N' in the Park was the first to be certified with a BREEAM New Construction rating. Since 2017, new developments and building renovations have been carried out in accordance with BREEAM New Construction criteria. Accordingly, during renovations, we strive to perform demolitions in a non-destructive manner and store the materials for reuse. Based on the principles of the circular economy, we often reuse demolished building elements (e.g., glass walls). In planning renovations and refurbishments, we consider the adaptability to tenant needs and long-term, sustainable use.

The Park uses the BREEAM In-Use certification system to certify the buildings it manages. Several of our buildings (M, N, S) have held a BREEAM In-Use Very Good rating since 2015, and we are currently working on renewing these certifications. In the coming years, our goal is to further increase the number of certified properties, including through the assessment of the G and South Park buildings; these are currently in the pre-certification phase and the data submission stage required for that. It is worth noting that in 2024, Building N advanced from its previous

"Very Good" rating to the "Excellent" category, and we expect Building M to achieve the "Excellent" rating in 2026 as well.

BREEAM in use certification

for two additional buildings by 2026

Beyond building certifications, we place a strong emphasis on expanding cycling infrastructure-such as providing bike racks, changing rooms, and service points-to support

active mobility. As a result, the Park earned the gold level of the Active Score certification in 2024, which remained valid in 2025. The certification confirms that the Park supports those who commute to work by bi-

cycle, scooter, and other active modes of transportation: it provides a sufficient number of bike racks for users and visitors, ensures a high level of security, has modern changing rooms and showers, and provides access to services that promote active commuting.

Energy consumption

Operating office parks involves significant energy use, making it crucial to increase energy efficiency, replace fossil energy sources, and integrate renewable energy sources into the energy mix.

Purchased electricity consumption Gasoline and diesel consumption Natural gas consumption

We meet the heating, cooling, and electricity needs of the Park's buildings using natural gas, pur-

chased electricity, and locally generated solar power. Our emergency generator is fueled by gasoline and diesel. Electric vehicles are becoming increasingly common in both our tenants' and our own vehicle fleets, and we provide charging facilities for them (see: Other Emissions section). In 2025, the Park's total energy consumption was 79,468 GJ.

Compared to 2024 figures, Graphisoft Park's total energy consumption increased slightly - by 3.44%

- in 2025. Within this, both purchased electricity consumption and natural gas consumption increased. As in the previous year, the main reasons for this can be found in the weather.

In 2025, unlike in previous years, it was not the summer heat that caused the greatest increase in energy consumption, but colder-than-usual winter temperatures. While the annual average temperature was 14.1 °C in 2024, it was only

12.9 °C in 2025. The number of days with freezing temperatures rose from 45 to 65, which is clearly reflected in the energy consumption data.2

² https://www.metnet.hu/napi-adatok?sub=5&pid=15321&date=2023

With ongoing mechanical maintenance and modernization of the buildings, our goal is to ensure uninterrupted use while also reducing the need for energy resources. We plan to implement further efficiency improvement projects in the future and are currently working on developing a multi-year development program related to these opportunities.

Use of renewable energy sources

Like prior years, throughout 2025, we ensured the complete green electricity supply for Graphisoft Park by purchasing guarantees of origin and

we plan to continue this practice. Meanwhile, we regularly explore the possibility of installing a solar park either within or outside the Park premises that could cover a larger portion of our electricity needs.

In previous years, there were two small solar farms operating within the Park, which were expanded starting in 2025, so that by 2026, annual solar energy production could increase to around 300,000 kWh. In 2025, the solar panels generated a total of 17,915 kWh of electricity, covering 0.13% of the Park's total electricity consumption.

The results show that, as in previous years, emissions from our own operations (Scope 1, 2) account for just over 3% of our total emissions (Scope 1, 2 and 3).

Since Scope 3 emissions account for most of our

total carbon footprint, reducing them is a top priority for us. Although these emissions are not under our direct control, monitoring and mitigating them remains a fundamental responsibility. Our Scope 3 figures are sig-

nificantly influenced by our tenants' decisions and operational practices, so we intend to place even greater emphasis on these in the future. This includes, among other things, reducing waste generation, promoting responsible material use, and encouraging lower water and energy consumption, which we intend to support through continuous and regular dialogue, for example, through tenant forums.

Our market-based emissions decreased by 3.6% compared to 2023, while our location-based emissions decreased by 10.1%. Compared to the previous year, 2024, we achieved improvements in nearly every metric. Our Scope 1 emissions decreased by 0.8%, and our Scope 2 location-based emissions by 9.9%. Our market-based Scope 2 emissions were zero, as in previous years, thanks to the purchase of green electricity. Regarding our Scope 3 emissions, we achieved a significant reduction of 11.5% (location-based) and 14.9% (market-based) in the Upstream segment. Only in the Downstream segment was there a slight increase (0.8%) in market-based emis-

sions. Overall, compared to 2024, our location-based emissions decreased by 5.7% and our market-based emissions by 6.51%.

Compared to 2022, which is considered the base year, the Park's total greenhouse gas emissions also show a downward trend. By 2025, total emissions had decreased by 14.7% according to the location-based methodology and by 12.4% according to the market-based methodology. Scope 1 emissions show a significant decrease of approximately 54.9%, while Scope 2 location-based emissions have decreased by 28.7% compared to the base year. For Scope 3 emissions, a more moderate but still downward trend can be observed: upstream emissions

decreased by 5.7% according to the location-based methodology (9.9% according to the market-based methodology), while downstream emissions decreased by 15.1% (8.4% according to the market-based

methodology). Overall, the data show

that emissions associated with the Park's operations have decreased in several emission categories compared to the base year.

Other emissions

In addition to greenhouse gas emissions, the daily operation of the Park is associated with a certain level of other air pollutant emissions, primarily originating from the use of vehicles by the tenants.

To minimize emissions from vehicle use, we support the use of electric cars. In previous years, electric chargers were installed based on individual requests, but in the second half of

2024 we have built identical chargers on uniformed terms, based on requests. In addition to metering and billing, this will also support energy management for each building, i.e. setting and monitoring optimal energy use. There are currently a significant number of electric vehicle charging stations, 186 in total, located within the park.

Additionally, the Park is easily accessible by bicycle and public transportation. For cyclists, numerous bike racks, changing rooms, and bike repair stations are available. We provide a shuttle bus service for the Park's tenants, connecting them with the city's public transportation (suburban trains, buses, and metro stations). This service is popular, with high usage rates, as 20-25% of the office park workers regularly use it. In the future, our goal is to provide an e-shuttle bus service for those using public transport.

As part of the modernization of our vehicle fleet, we have begun introducing hybrid and electric vehicles into our company fleet. By 2025, 86.6% of the company's vehicles will be powered by alternative drive systems (plug-in hybrid, electric).

Reducing climate risks

Graphisoft Park is affected by climate change and its consequences, including high summer temperatures, increasing occurrences of showers and thunderstorms, as well as droughts and water scarcity.

For now, the Park's high-capacity cooling equipment provides an adequate solution for high summer temperatures, and there are no issues thus far. However, areas requiring development have been identified, such as the need to manage the quantity and quality of internal heat emitters in some older buildings.

Additionally, the Park's green areas contribute to creating a favorable microclimate. If the Park's surface were mostly paved with asphalt or paving stones, it would be much warmer on hot days, and the sensation of heat would be worse. The cooling effect of shade-providing trees and evaporating plants (this effect is also called

"evapotranspiration") is particularly noticeable on these days. On Budapest's heat map, areas with high vegetation coverage show significantly lower surface temperatures compared to densely built-up areas, a benefit further enhanced in the case of Graphisoft Park by the proximity of the Danube.

Although Graphisoft Park's stormwater drainage system was not sized for sudden heavy rainfall, the vast green areas provide sufficient absorption capacity. Considering the expected summer heat and drought, we have planted indigenous plants that tolerate local climatic conditions well on the Park's territory. Our goal is to maintain sustainable green vegetation throughout the summer months without excessive use of (drinking) water.

Surface temperature

Graphisoft Park is committed not only to improving the condition of green spaces but also to participating in the development of a new generation of climate-adaptive urban green infrastructure. Due to increasingly frequent extreme weather conditions, traditional urban stormwater management is not sustainable in the long term. Therefore, in 2025, our company began implementing the sponge city model ("szivacsvâros-modell"), which treats rain not as a problem to be drained away, but as a valuable resource to be utilized locally. With the sponge city approach, surface water

utilization can be operated as a decentralized system. By improving soil structure and directing water into the root zone, natural infiltration, and thus plant vitality, can be enhanced. We have established several pilot projects in the Park, such as directing rainwater from paved surfaces to green areas, creating drainage beds, collecting roof runoff from buildings, and aerating compacted soil. These measures improve natural water dynamics and the local microclimate.

attention to the conscious selection and use of materials.

The principle in renovations is to consider existing conditions, perform the least amount of intervention possible, and minimize demolition waste and construction material needs, practically implementing the principle of circularity. Accordingly, a significant portion of the usable, good condition elements resulting from demolition activities (e.g., doors, glass walls, ceiling elements, lamps, floor boxes, switches, mechanical elements) are reused wherever possible. This approach reduces the quantity of new materials required, their environmental impact, and costs.

Among the materials and elements procured, those made from recyclable or recycled materials are preferred for environmental reasons, as they have a lesser environmental impact than their traditionally produced counterparts. Examples include gypsum boards made partly from power plant gypsum and partly from recycled gypsum and paper. Mineral fiber ceiling tiles, carpet, and PVC floor coverings are also partially made from recycled materials and are recyclable.

Water Consumption

The water demand of office buildings and service units is primarily supplied from the drinking water network, while irrigation primarily uses well water.

Due to the numerous built-in water-consuming appliances, devices, and sanitary fittings used daily by building users, our impact on water consumption is significant. Therefore, monitoring water usage is crucial, as is regularly providing feedback to tenants and informing them of measures to reduce water consumption.

When selecting household appliances that use water, the amount of water consumption was a critical consideration, with 75% of dishwashers being low water usage models. Minimizing water demand was also a key criterion in selecting sanitary equipment; additionally, some buildings have flow reducers in the water blocks, with plans to expand these soon.

The extensive green areas on the Park's premises (including ground-level and extensive green roofs) contribute to creating a pleasant microclimate, evaporation, and storing rainwater. These areas also play a crucial role in draining large amounts of rainwater simultaneously.

Most of the generated wastewater is of a communal nature, thus it does not require pretreatment before being discharged to the sewage treatment plant. There are several kitchens and catering units within the Park, which have local pretreatment systems, grease and oil separators, and grease and oil traps that pretreat the wastewater before it enters the sewer system. Additionally,

the vehicular areas have light liquid separators and outlets. The pollutants captured by these systems are transported off-site as waste from the Park. The wastewater is conveyed from the Park to the treatment plant through a built sewer network.

Waste management and waste reduction

Minimizing waste generation and recycling the waste generated benefits everyone, as it not only ensures a clean, livable environment but also reduces primary raw material usage and costs.

Reducing and minimizing the amount of waste generated has always been a priority, having placed a lot of emphasis on this from the beginning.

We achieve the greatest impact through the conscientious implementation of renovations and conscious material usage. During procurement, we prefer high-quality, long-lasting materials and products to minimize premature waste generation.

We encourage our tenants to choose recycled or used materials and elements during fit-out installations, contributing cost-effectively to the principle of circularity.

Due to the operation of restaurants, cafes, and eateries linked to daily office activities in the Park, reducing food waste is particularly important. Several self-service and weight-based restaurants in the Park help reduce food waste by serving personalized portions, ensuring people only take as much as they will consume. Our menu-based restaurants optimize portion sizes. At the end of the process, to utilize the inevitably

remaining food, some restaurants in the Park collaborate with Budapest Bike Maffia. Through their "Emergency Food Rescue" project, they save consumable warm meals and food items, distributing them to those in need, thereby contributing to the fight against climate change by reducing food waste.

Outdoor bottle filling stations have been introduced in the Park to minimize plastic waste generation. These allow Park visitors and workers to easily refill their water bottles with refreshing water.

If a material, product, or food becomes waste, the next steps are proper collection, reuse, recycling, or disposal.

Types and amounts of waste generated

Waste is generated primarily from tenant activities and our own operations, particularly from maintenance activities. We have control primarily over our own waste generation, but we also have some influence over waste generated from our tenants' daily activities in the Park and from the infrastructure and services that support it.
