NXTBLDNG as the foundation for green bond analysis at NN Bank

In a real estate market where transparency and sustainability are increasingly vital, access to validated building data is essential. To help property stakeholders gain insight into performance, risks and opportunities, CFP Green Buildings developed the data platform NXTBLDNG. This central source of building information now also serves as the foundation for NN Bank’s green bond analysis.

NXTBLDNG: one platform for reliable and scalable building data

The NXTBLDNG (Next Building) digital twin platform automatically collects, enriches and makes building data accessible at address level. It combines validated sources and climate risk analyses with CFP’s proprietary calculation models and algorithms. The result is a complete digital building profile, including:

• Building characteristics such as year of construction, function and floor area;
• Energy performance, including energy labels and consumption;
• Physical features such as insulation levels and glazed surface area;
• Climate risks including heat, drought and flooding;
• Retrofit measures with corresponding investment costs.

This results in a reliable dataset containing, among other things, carbon emissions, EPCs, surface area and retrofit costs. The dataset supports green bond applications by providing trustworthy input for impact reporting.

How NN Bank uses NXTBLDNG for green bond analysis

NN Bank uses green bonds to finance sustainable mortgages and reach a broader group of investors. Once green assets meet the criteria of the EU Taxonomy, reporting on their climate impact becomes mandatory, including under the ICMA Green Bond Principles.

NXTBLDNG provides the required building data to report on climate risks, energy performance and carbon emissions in a clear and substantiated way. This approach enables NN Bank to:

• Identify eligible green assets in line with the EU Taxonomy;
• Assess whether a property ranks among the top 15 percent most energy-efficient homes in the Netherlands;
• Calculate carbon emissions, energy and gas use per property;
• Gain a portfolio-wide overview and benchmark it against national averages;
• Monitor the greening of the portfolio year-on-year in a transparent manner.

Outcome: insight, scale and impact

While NXTBLDNG offers a wide range of data fields, the energy, carbon and retrofit indicators already provide critical insights for NN Bank’s green bond impact reports. Thanks to the platform’s scalability, properties can be assessed efficiently and objectively, without manual data collection.

The collaboration between NN Bank and CFP Green Buildings contributes to a future-proof real estate portfolio, where reliable data underpins sustainable financial decisions.

By adopting CFP’s NXTBLDNG platform, NN Bank strengthens its sustainable finance strategy. Structured and scalable access to real estate data gives the bank deeper insight into the climate impact of its portfolio. This creates a solid foundation not only for green bond reporting, but also for forward-looking investment decisions and transparent communication with investors.
