Low-carbon renovation: how can digitalization maximize the impact of work?

Faced with the growing demands of the ecological transition, low-carbon renovation has become a priority for property asset managers. However, reducing the carbon footprint of renovation work is not limited to improving the energy efficiency of buildings. It is now essential to integrate all emissions from a building’s lifecycle, particularly those linked to materials and renovation sites(Scope 3), which can account for up to 90% of an asset manager’s total carbon footprint.

By digitizing your property portfolio, you cananticipate the environmental impact of renovations, compare several scenarios and maximize carbon gains while optimizing costs.

1. Why is low-carbon renovation an essential lever for real estate?

A response to new environmental regulations

Carbon performance standards for buildings are becoming increasingly stringent:

• The European taxonomy imposes carbon emission thresholds for an asset to be considered sustainable.
• France’s RE2020 incorpor ates embedded carbon in construction and renovation materials.
• Environmental labels (BBCA, HQE, BREEAM) now require Scope 3 reduction initiatives.
• Operating labels (OsmoZ, BREEAM In-Use, HQE Exploitation, LEED O+M) require precise monitoring of the building’s environmental performance, making the use of an asset digitization tool essential.

If you don’t integrate these constraints today, you run the risk of seeing your assets become obsolete, and of incurring high compliance costs.

Scope 3: the next frontier in real estate decarbonization

While efforts to reduce emissions have long focused on the energy performance of buildings (Scope 1 and 2), they remain insufficient to achieve carbon neutrality.

Scope 3, which includes materials in the operating, renovation and end-of-life phases of buildings, is often the forgotten part of low-carbon strategies. Yet it represents :

• Up to 50% of new building emissions (embodied carbon in materials).
• Up to 90% of a property portfolio’s emissions when construction sites and waste management are included.

A poorly planned renovation can therefore generate more emissions than it saves in the long term, hence the importance of an approach based on digitalization and anticipation of carbon impacts.

2. Digitization: a key tool for optimizing the impact of renovations

Evaluate the carbon footprint of work before taking action

Thanks to real estate asset digitization tools, it is possible toanalyze the carbon impact of an existing building and simulate several renovation scenarios.

• Identification of existing materials and calculation of their carbon footprint.
• Quantification of emissions generated by different renovation options.
• Simulation of long-term carbon gains to compare the most efficient solutions.

This approach makes it possible toavoid carbon-intensive renovations and choose the best performing options from an ESG point of view.

Compare several strategies for reducing Scope 3

Digitization tools make it possible to evaluate several alternatives for a single renovation project:

• Renovation with conventional new materials → High carbon impact.
• Reuse and low-carbon materials → Significant reduction in Scope 3.
• Change of use of the building to limit major interventions → Strategy with controlled carbon impact.

Rather than applying standard solutions, digitalization means thateach project can be tailored to minimize the carbon footprint of the work.

Optimizing waste management and re-use

One of the main levers for reducing Scope 3 is the integration of the circular economy into renovation work:

• Inventory materials that can be reused directly on site or in other projects in the portfolio.
• Reduce construction waste by limiting systematic demolition and making the most of existing resources.
• Promote local re-use channels to minimize the carbon impact of transporting materials.

Digitization makes it possible to integrate these strategies right from the project design stage, guaranteeing a renovation with low environmental impact.

3. Maximizing the carbon impact of renovation work by aligning renovation and ESG financing

Access to green financing and sustainable bonds

ESG financiers and investors prefer projects with a well-defined carbon trajectory. Thanks to digitalization, asset managers can :

• Demonstrate the alignment of their renovations with the criteria of the European taxonomy.
• Make it easier to obtain green financing and sustainable bonds by proving the low-carbon impact of the work.
• Improve the ESG rating of real estate assets to make them more attractive to investors.

A well-modeled renovation can therefore maximize environmental benefits while securing access to sustainable financing.

Anticipate future standards to avoid additional costs

By integrating carbon modeling, it is possible to anticipate regulatory changes and compliance obligations:

• Integration of future emission thresholds to avoid unnecessary short-term renovations.
• Optimize costs by avoiding costly and time-consuming upgrades.
• Planning of operations to align sites with the requirements of environmental labels and certifications.

This approach optimizes investments and avoids costly corrections in the future.

4. Towards a systematic approach to low-carbon renovation

Gradual but inevitable adoption

With the rise in ESG requirements, taking Scope 3 into account is becoming a necessity for real estate asset managers. Those who adopt low-carbon renovation strategies today will benefit :

• Easier access to sustainable financing.
• Better anticipation of regulatory requirements.
• Increased market value for their assets.

A lever for securing the competitiveness of real estate portfolios

Integrating carbon modeling – or forecasting – into renovation projects offers several advantages:

• Reduce costs over the long term by minimizing unnecessary intervention and late compliance.
• Better control of regulatory and financial risks linked to market developments.
• Optimized asset value by ensuring alignment with environmental standards.

Managers who take a proactive approach to low-carbon renovation will be best positioned to meet market demands and maximize the performance of their assets.

Conclusion: structuring low-carbon renovation to maximize its environmental and financial impact

Optimizing renovation work can no longer be limited to reducing the energy consumption of buildings. Scope 3 integration and on-board carbon modeling are now essential levers for guaranteeing truly sustainable, high-performance renovation.

Digitizing real estate assets makes it possible to :

• Optimize renovation choices by comparing several scenarios.
• Integrate the circular economy and the re-use of materials to reduce the carbon footprint of the work.
• Securing green financing and maximizing asset value.

Tomorrow’s real estate will be low-carbon, circular and data-optimized. Those who anticipate this transformation will enjoy a sustainable competitive advantage.
