This certification represents a significant milestone for the company, as it validates its continuous efforts to establish, implement and maintain a solid Information Privacy Management System (IPMS).

- **Competitive advantage:** ISO 27701 certification makes a difference in a competitive market by demonstrating commitment to the highest standards of information privacy management, opening up new business opportunities and strengthening relationships with existing customers.


"This certification helps to guarantee compliance with a fundamental principle of the GDPR, the principle of proactive responsibility, which means that organisations adopt the appropriate technical and organisational measures not only to comply with the regulation, but also to demonstrate their compliance, and to commit to continuous improvement," says Ángeles Martínez, Head of Digital Business and Data Protection in Accumin's Legal Department.

This certification is in addition to those already obtained by the Group's companies in Spain, Portugal and Morocco: Tinsa Spain, Tinsa Digital, Balkide, PVW Tinsa Portugal and Tinsa Maroc.

Accumin adquiere la consultora energética y de sostenibilidad Zero Consulting

**Accumin** has acquired energy and sustainability consultancy **Zero Consulting**. With offices in Barcelona and Madrid, Zero Consulting specialises in advising on **sustainability in real estate development projects** (design, simulation and parameterisation in BIM technology, circularity and carbon footprint) and the management of sustainable buildings with low energy consumption, as well as consultancy for the certification of LEED, WELL, DGNB, BREEAM and VERDE projects (measurement and approval). 

Although it operates mainly in Spain, Zero Consulting has begun to internationalise its activities, with projects in Europe, Latin America and the Middle East. (More info at www.zeroconsulting.com).

Accumin thus expands the scope of its energy services in international sustainable certification, in the analysis of sustainability from the origin of new building projects and in the study and improvement of the energy performance of buildings and their life cycle. 

Sustainability is one of Accumin's strategic growth areas, an expertise presents in its three business verticals: Value & Advisory, Intelligence & Software and Risk Management. Accumin has positioned itself as one of the leading companies in this field, both in energy performance certification in Spain and Germany and in the analysis of energy efficiency data and natural and climate risks for many European financial institutions.

"We are delighted to add Zero Consulting's expertise to our family. With their help, we are adding new capabilities to offer 360º coverage in sustainability applied to real estate assets. The sum of knowledge and diverse perspectives under the global Accumin brand makes us the best partner to support citizens, companies, the financial sector and the public administration in the goal of promoting efficient and sustainable buildings and urban environments"

In Spain, Deyde DataCentric by Accumin (part of Accumin Intelligence) has been chosen by the Ministry for Ecological Transition and the Demographic Challenge (MITERD) to design, build and validate a unified database of energy certificates at national level. 

Accumin Intelligence’s technological capabilities are supported by the knowledge in energy consultancy and the housing market of Tinsa España by Accumin, the largest real estate valuation company in the country, which has carried out more than 110,000 energy performance certificates since they became compulsory in Spain to sell a home or rent a property. Tinsa España by Accumin has helped thousands of homes to benefit from Next Generation funds totalling €7.8 million for efficiency improvements that have reduced their cooling and heating demand by an average of 7%.

"We are delighted to add Zero Consulting's expertise to our family. With their help, we are adding new capabilities to offer 360º coverage in sustainability applied to real estate assets. The sum of knowledge and diverse perspectives under the global Accumin brand makes us the best partner to support citizens, companies, the financial sector and the public administration in the goal of promoting efficient and sustainable buildings and urban environments", says James Cornell, Chairman & Global Chief Executive Officer of Accumin.

Artur García, CEO of Zero Consulting, points out: "Joining forces with Accumin is a new challenge that will allow us to offer our sustainability consulting services to a wider portfolio of clients and in geographies where we are not yet present. It is a great opportunity for the whole Zero Consulting team to growth and consolidate, contributing our know-how in sustainability consulting and offering our own software tools developed for life cycle analysis and nZEB building design to a much larger number of clients".


Tinsa Mexico by Accumin obtains the ISO 27001 certification for information security 

News 21.jpg

**Tinsa Mexico by Accumin** is the first Accumin company in Latin America to obtain ISO 27001 certification, the most prestigious international standard for information security management.

This certification places Tinsa Mexico by Accumin in a differentiated position in the highly competitive Mexican market. ISO 27001 certification is much more than regulatory compliance. In a context where cybersecurity threats are increasingly common, a solid information security management system is essential to protect the confidential data of our customers, employees and partners,' says Jesús Orozco, General Manager of Tinsa Mexico by Accumin.

The ISO 27001 standard guarantees that the company complies with the highest international standards for managing and mitigating risks and ensuring the confidentiality, integrity and availability of information.

The certification is the result of an exhaustive process that took almost a year of continuous work, as ISO 27001 requires the implementation of strict security controls, internal and external audits and the coordination of local and global teams.

ISO 27001 certification involves not only technology, but also a comprehensive approach to organisational processes and security culture.

News & Events

Persch Consult by Accumin at EXPO REAL 2024

**Persch Consult by Accumin** had a prominent presence at **Expo Real 2024**, the leading international real estate event. During the fair, the company not only engaged in numerous strategic discussions with industry professionals but also received the prestigious Approved by HypZert GmbH trophy. 

The Persch Consult by Accumin team was represented by key members including **Christian Schuhmann MRICS, Steffen Berger FRICS, Marios Antonios Batsilas FRICS, Marcus Steede, Daniel Risso**, and **Eileen Winterholt**, who played a vital role in building new partnerships and promoting the company’s services.

Expo Real is the most important trade fair for the real estate industry and therefore offers a fully comprehensive overview of developments, topics, innovations and solutions in the real estate industry. In this way, it provides the necessary orientation in a time of upheaval.


Acumin sponsors the RICS Built Environment European Summit 2024

News 19.jpg

Accumin participated as Silver Sponsor in the second edition of the RICS Built Environment European Summit, held on 14 and 15 October at the Azkuna Zentroa in Bilbao (Spain). The event, which brought together 300 professionals, explored how the property sector, and cities in particular, can move towards a more sustainable context in line with global objectives.

Accumin was well represented at the event: **Maarten de Haas**, Global Head of Value & Advisory; **Manuel Hurtado**, Global Head of Intelligence; **Belén Dávila**, Director RICS Value & Advisory Services at Tinsa España by Accumin; **Raquel Gómez**, Head of Valuations & RE Specialist in urbanData Analytics (uDA) by Accumin; and **Pedro Mestre**, Director of PVW Tinsa by Accumin.

The debate revolved around topics such as ESG, sustainability, taxonomy, renovation, urban transformation or the risks involved in raising stakeholder awareness of the importance of socially responsible investment, the decarbonisation of the real estate sector, the integration of sustainability in investments or the concept of climate-resilient cities.


The exchange of ideas and networking led to conclusions such as:
- To achieve carbon neutrality by 2050, it will be necessary to renovate the existing building stock, as 85% of the current buildings will still be standing by that date.
- Brown risk or green premium? Although there is currently no evidence of an immediate fall in the value of non-green assets, there is a growing perception that an asset that does not meet a high standard of energy efficiency has fewer potential buyers than others.
- Reducing consumption, improving energy efficiency, reusing materials and finding more efficient and technological models for developing property products are some of the challenges facing the various players.
- The impact of regulation and legislation, standards and risk management play an important role and are seen as a turning point for the sector.
- Value, data and risk form a triangle that puts Accumin on the right track to contribute to the sustainable development of real estate.


Accumin holds its Strategy Days in Madrid

News 18_1.jpg

More than 40 leaders from across the Group's geographies met in Alcalá de Henares (Madrid, Spain) to celebrate success, share strategy, drive new projects.

It was three intense days of work to have a clear vision of where Accumin is and look at the future with our 3-5 years plan. Accumin’s leaders learned more about the challenges of each of the three global business verticals (Value & Advisory; Intelligence & Software and Risk Management) and all the innovations that are being cooked up in the transversal and disruptive area of Accumin Home.

The Strategy Days sessions challenged leaders from 14 countries to think outside the box and innovate on behalf of customers. They also participated in presentations and workshops to understand themselves as a team and explore the values that underpin the new global corporate identity: Act with Integrity, Lead the Way and Unite as One. 

Accumin as the new global brand to drive better real estate decision-making

17_strategy_days.jpg

**Asertia**, the global real estate group owned by the international private equity firm **Cinven** and known in the real estate sector as **Tinsa Group**, has announced plans to reorganize and more clearly define its diverse range of products and services worldwide.

The group behind market leaders Tinsa and Deyde DataCentric (Spain and Latin America); Persch Consult and on-geo (Germany); and Troostwijk (Netherlands), among others, unites its companies under a new group name: **Accumin**.

As one of the world’s largest and most trusted real estate advisory companies with more than 40 years of experience, Accumin has one clear purpose: to empower people and businesses to grow by making the right real estate decisions and see value clearly. As part of redefining the group, Asertia combines its collective products and services under three core verticals to bring greater clarity on the group’s capabilities: **Value & Advisory**, **Intelligence & Software**, and **Risk Management**. 

In addition to the three verticals, there will also be a new transversal division called **Home**, which will primarily focus on bringing greater clarity and efficiency to help consumers make better real estate decisions as buyers, sellers and owners of real estate. 

“Value is everywhere if you know how to look. In a world that is increasingly uncertain, our aim is to bring precision, clarity and innovation, and build trust with our clients, identifying opportunities and risks that might otherwise go unnoticed. This is an exciting phase of our present and future evolution as a combined group that demonstrates our overall capabilities in independent expertise and innovative intelligence and software solutions. Our purpose is to help our clients, and their customers see value clearly, building upon our reputation as a company that clients can trust to provide them quality and independent, unbiased advice,” said **James Cornell, Chairman & Global Chief Executive Officer of Accumin**. 


“Our strength and our value lie in our integration of independent diverse perspectives from various countries, sectors, and disciplines, which gives us a global vision backed by local expertise, strengthening our ability to cut through complexity, providing value and clarity to our business customers and to the end consumer”

To strengthen the company’s strategic global vision, Accumin has named experts to lead its newly defined structure:
- **Maarten de Hass** has recently joined as the **Global Head of Value & Advisory**. Maarten has significant international real estate experience in multinational companies and brings with him years of working in consulting firms such as MVGM, Cushman, Deloitte and EY.
- **Manuel Hurtado** also recently joined as the **Global Head of Intelligence**. Coming from the strategy and technology consulting firm McKinsey, Manuel has been a key leader in their data and Gen AI area and has more than a decade of international experience in data strategy, digital transformation and analytics.
- **Johan Drost**, current CEO of Troostwijk Group, a subsidiary of Accumin, has been appointed **Global Head of Risk Management**. Here Johan combines his background within banking and insurance to help build on Troostwijk’s vast products and services from risk inspection to Real estate loss assessing and valuation for insurance purposes.  
- **Jose Rivera**, current Group Head of Digital will lead the transversal, and newly created consumer-focused division and become **Global Head of Accumin Home**.

“Our strength and our value lie in our integration of independent diverse perspectives from various countries, sectors, and disciplines, which gives us a global vision backed by local expertise, strengthening our ability to cut through complexity, providing value and clarity to our business customers and to the end consumer,” adds James Cornell. “By amplifying our human perspective with intelligence and software, we give clients greater control and confidence over real estate related decisions, which is what will be key to helping our clients and their customers see value clearly.”

Today’s repositioning of the group under the global brand of **Accumin** is the beginning of a wider unification in how the company presents itself, working together whilst respecting regulation to preserve independence and data protection between its subsidiaries. While the company envisions most of its companies to ultimately rebrand as **Accumin**, most subsidiaries will first pass through a transition period in which they will be endorsed “by Accumin” to respect the powerful reputation that the individual companies have built in their local markets. 

Accumin transforms into an ecosystem of local and global expertise, harnessing the power of the diversity of its talent supported by intelligence and software, true to its name: the combination of knowledge, or acumen, and accuracy or precision, which are central to the value proposition the company offers for clients.

##### About Accumin

Manuel Hurtado Card.jpg

**Persch Consult GmbH | Chartered Surveyors**, a **Tinsa Group** company, has been awarded the Gold Medal by **EcoVadis**, recognizing its commitment to sustainability and corporate social responsibility.

EcoVadis is a global sustainability rating platform that evaluates companies' performance in environmental, social, and ethical dimensions. The comprehensive assessment covers 21 criteria across four themes: Environment, Labour & Human Rights, Ethics, and Sustainable Procurement.

Achieving the Gold Medal is the result of a concerted effort across all levels of Persch Consult organization and the Tinsa Group. This is the second time that Persch Consult has received an EcoVadis medal, whereas last year it received the Bronze Medal.
Receiving the Gold Medal from EcoVadis is not just a badge of honor, it represents an ongoing commitment to sustainable growth.

Bronze for on-geo

News 14.jpg

It's clear: companies need effective sustainability management to minimize the negative impacts of their activities on the environment and society. At **on-geo**, we also place great importance on improving our sustainability performance and thus making a positive contribution to future-proof and ethical supply chains. This is precisely where CSR (Corporate Social Responsibility) ratings come into play.

**EcoVadis** is now the world's largest provider of sustainability ratings for global supply chains. Founded in Paris in 2007, EcoVadis assesses over 130,000 companies in 175 countries worldwide – and on-geo joined this year. The EcoVadis rating examines 21 sustainability criteria in four areas: **environment, labour and human rights, ethics, and sustainable procurement**. The criteria are based on international standards such as the ten principles of the UN Global Compact, the conventions of the International Labor Organization (ILO), the Global Reporting Initiative (GRI) standard, and the ISO 26000 standard.

The assessment methodology aims to measure the quality of a company's sustainability management system based on three management pillars: policies, actions, and the reporting of results and key performance indicators (KPIs). This concept is based on the PDCA (Plan, Do, Check, Act) cycle, which forms the foundation for many management systems worldwide. Using a questionnaire that takes into account a company's industry, size, and location, information and evidence on sustainability performance are collected and analyzed. The assessment result is communicated via the scorecard and remains valid for twelve months.


Overall, we achieved 63 out of 100 points in the initial assessment in 2024, placing us in 81st percentile. By comparison, other companies in our "Information Technology Services" sector received an average score of 53 in 2024. EcoVadis' overall assessment also shows that on-geo is among the top 13 percent of assessed companies in this sector. We performed particularly well in the areas of environment, labor and human rights, and ethics, compared to our industry: **60 points in the environment, and 70 points in labor and human rights, and ethics**. However, in the area of "Sustainable Procurement," on-geo only achieved the rating "incomplete." This corresponds to the modal value, i.e., the number of points awarded most often to companies within this category.


The achieved percentile (81st percentile) means our score is equal to or higher than 81 percent of the companies participating in the EcoVadis rating, meaning only 19 percent performed better. This immediately earned us **Bronze**, placing us among the **top 35 percent** (65th percentile or higher) of all companies rated across all industries over the past 12 months.

Another important part of the rating is the so-called "360° Watch" results: These contain relevant public information about a company's sustainability practices, compiled from more than 100,000 data sources (including NGOs, the press, and trade unions). The results are incorporated into the assessment and can have a positive, negative, or neutral impact on the score. Our 360° Watch result was **without any anomalies** and was therefore **rated as good**.

For us, the EcoVadis rating is an important tool for illustrating, reflecting, and evaluating our sustainability performance. Above all, our achieved percentile ranking demonstrates that we are significantly above average in terms of environmental protection, social responsibility, and ethical corporate governance. This positive sign motivates us to continue improving and to continue to focus on sustainable business practices in the future.

**Deyde DataCentric**, a Spanish technology company specialized in data quality, geolocation, and information validation and enrichment, and a member of the group, has signed a collaboration agreement with the **Ministry for Ecological Transition and the Demographic Challenge** (MITERD in Spanish) for the design, development, and implementation of a unified national database for Energy Performance Certificates (EPCs) in Spain.

This cooperation agreement between Deyde DataCentric and MITERD will allow the creation of an efficient system of shared and updated information to know exactly the energy situation of the residential stock and facilitate the control and identification of deficiencies and possible errors in the EPCs.

'In addition to our experience in database management, validation and enrichment, we will contribute our knowledge of energy consulting and the housing sector, which comes from being part of the Tinsa Group. Deyde DataCentric has developed the algorithm for modelling energy performance certificates that enables Tinsa to catalogue the energy efficiency level of every house in the country'

Deyde DataCentric will be responsible for designing, building and implementing this single database of validated, corrected and enriched energy certificate information at the property cadastral reference level during the 4-year contract.

“In addition to our experience in database management, validation and enrichment, we will contribute our knowledge of energy consulting and the housing sector, which comes from being part of the Tinsa Group. Deyde DataCentric has developed the algorithm for modelling energy performance certificates that enables Tinsa to catalogue the energy efficiency level of every house in the country," explains Deyde DataCentric.

Supported by this technological expertise and its energy and real estate consultancy, Deyde DataCentric will be responsible for enriching and validating the information in the registers of the Spanish Regions updated data from additional public sources and with information exclusively owned by Deyde DataCentric.

This public-private partnership initiative will improve the quality and structure of information on residential energy efficiency in Spain. By validating that the information on the certificates is consistent and meets the technical criteria, it will provide a true aggregate picture of the energy situation of the housing stock. This transparency is essential to promote public policies that help citizens improve the energy efficiency of their homes, in line with the objectives set by Europe,' the company explains.

Deyde DataCentric will also provide the technological infrastructure in the cloud under the main international information security standards, as it has the prestigious ISO 27001 certification from Aenor.
