Real Estate price transparency

[The Bank of Spain and the Ministry of Housing have recently signed a cooperation agreement to improve the analysis of the housing market in Spain.](https://www.europapress.es/economia/construccion-y-vivienda-00342/noticia-banco-espana-ministerio-vivienda-colaboraran-mejora-analisis-mercado-vivienda-20250630145420.html) This agreement aims to strengthen the quality of the information available, foster collaboration between both institutions, and advance toward a deeper and more structured understanding of the real estate and housing sector. Among its objectives are the creation of a shared data space and the joint development of analytical projects.

Reinforcing this move toward greater market insight, [the Bank of Spain has also entered into a new agreement with the General Council of Notaries](https://www.eleconomista.es/legal/noticias/13466847/07/25/el-consejo-general-del-notariado-y-el-banco-de-espana-firman-un-convenio-para-reforzar-el-analisis-del-mercado-inmobiliario.html). This collaboration is designed to further strengthen real estate market analysis by leveraging the precise and detailed data generated through notarial activities, complementing the broader push for enhanced data quality and research.

At Accumin, we see this development as an opportunity to improve transparency and build trust across the entire residential ecosystem; including a genuine conversation we believe is essential: the need to improve transparency around actual sale prices as a lever for a less opaque and a more precise and trustworthy sector. 

We’ve been working for some time with ﬁnancial institutions and other sector stakeholders to promote more accurate, data-driven, and calibratable models. Spain has a complex system in terms of access to real sale price information: the data exists, but it is subject to access restrictions, aggregation, and time lags. Even so, we believe there is room for progress — even without major legislative changes.

There are useful examples across Europe. In the United Kingdom, actual sale prices are openly accessible to all market participants. In Germany, although the real sales prices data is not public, there are systems in place so that appraisal ﬁrms and banks have access to real data allowing them to improve the quality and consistency of their valuations and risk assessments. Both models show that there are viable ways to make better use of available information and raise industry standards.

Improving transparency beneﬁts all stakeholders in the residential ecosystem: citizens and consumers, who can make better-informed decisions; ﬁnancial institutions, which can manage risk more effectively; and supervisory authorities, which gain more reliable tools to assess market conditions.

The recent announcement from the Bank of Spain and the Ministry of Housing opens the door to further progress in this direction. Not only from an institutional standpoint, but as part of a broader cultural and technical shift already underway.

At Accumin, we will continue contributing our experience, technological capabilities, and international perspective to support the evolution and trust on a real estate and housing market that is more efﬁcient, more transparent, and better aligned with the real needs of all its participants.

Accumin and IESE prove the link between energy efficiency and home value in Spain

Spain's largest property valuation company, Tinsa by Accumin, the data and market analytics platform Accumin Intelligence, and IESE Business School have published the first report to statistically demonstrate the impact of energy efficiency on house prices in Spain, isolating the influence of other correlated variables.

The study, 'Energy Performance and Residential Property Value in Spain', is based on a representative sample of 243,414 properties collected between 2012 and 2024. It shows that energy efficiency has a significant and positive impact on the value of homes, consistently across different regions, property types, price ranges and ages.

For each of the dwellings, the variables of energy performance certificate, surface area, age, location, construction characteristics and valuation were analysed. Using discontinuity regression design, the authors were able to isolate the specific impact of energy efficiency on house value from other correlated factors.

More efficient homes also tend to be more modern, with better construction quality and higher prices,' explains Cristina Arias, Director of the Tinsa by Accumin Research Department and one of the authors of the report. At first glance, it is difficult to distinguish whether the market places a higher value on energy-efficient properties because of their energy-efficiency characteristics, thus incorporating the value of the energy savings that the property will provide in the future, or whether, on the other hand, the higher value is due to other factors related to construction quality, which are paid for during construction or renovation and are more tangible at the time of purchase. When analysing energy efficiency, it is common to ignore these correlations, leading to misleading results.

Arias emphasises that the model captures how houses that are structurally the same, differing only in the letter of their energy certificate, have different values. The impact is therefore exclusively due to the improvement in the energy rating, isolated from the influence of other variables," he explains.

The results of this study, which includes a complete analysis of the efficiency of the Spanish housing stock by age, type or climate zone, show the existence of a 'green premium' in the Spanish housing market, where better CO₂ emission ratings translate into higher property values.

Here, the 'green premium' is defined as the percentage increase in the price of housing associated with an improvement in the energy rating of the property. This concept reflects how the market positively values properties with higher levels of energy efficiency, as they incorporate both future savings in energy costs and a contribution to environmental sustainability," says Arias.


Looking at the whole sample and averaging across all letter transitions, it is estimated that a one-letter improvement in energy efficiency increases the price of a home by an average of 1.3%.

A larger impact is observed for the transitions of properties belonging to efficient categories (C-A) compared to transitions between inefficient categories (G-D). For example, there is an increase of 1.2% when moving from E to D, 2.1% when moving from B to A and up to 3.3% when moving from C to B.

'The study shows that the increase in value associated with greater energy efficiency is not limited to the higher-priced properties in the premium or luxury segment, nor to detached houses as opposed to apartment blocks, nor to specific locations, but is an attribute that is valued in all market categories,' says Arias.

##### Growing trend

The study concludes that energy efficiency contributes to property revaluation. Although it currently has a moderate direct impact on the value of housing, its importance is consistent across all segments, and it is positioned as a key factor in determining market prices.

Historical analysis shows a growing trend in ‘green premium', which corresponds to a higher valuation of sustainability, due to both the environmental awareness of housing demand and the application of stricter regulations on energy efficiency.


The results suggest that we are at the beginning of an upward trend in the valuation of efficient properties and a relative devaluation of inefficient ones.

It is reasonable to expect that the importance of energy efficiency will gradually increase as stricter regulatory policies on CO₂ emissions and energy consumption are applied. For example, the introduction of more demanding European and national regulations, such as the recent EU Energy Efficiency Directive and its transposition into Spanish legislation, will force owners to invest in improving the energy performance of their properties,' says Cristina Arias.

Access the full report

The interaction between the operational savings generated by improvements in energy efficiency, regulatory standards and greater environmental awareness among consumers will contribute to increasing the 'green premium' in the coming years, positioning energy efficiency as a strategic factor for the future of the real estate sector, concludes the study.

Persch Consult by Accumin at Expo Real 2024

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.
