Moving from End-of-Cycle Reporting to Continuous Insight
Luc: Rudy, first of all, congratulations on another strong GRESB performance with both your funds. We’re proud to have supported you along the way. Could you share how Scaler has helped improve your ESG data process?
Rudy: Before Scaler, we worked with a consultant who collected all our ESG data—reading smart meters, compiling invoices, and gathering information from grid operators—before entering everything into the GRESB spreadsheet. It worked, but we only saw the results at the end of the reporting cycle.
That meant we discovered missing or incorrect data very late in the process. Now, with Scaler, we upload everything into the platform early in the year and can monitor progress in real time. We immediately see which assets need attention, where data is missing, and whether we’re on track. We’re much more in control throughout the process, rather than waiting until the final moment.
From Reactive to Proactive
Luc: That sounds like a big change. Has this visibility spread across the organization?
Rudy: It’s starting to. The ESG team uses Scaler daily and we share many insights across the company—for instance, in our annual report or ESG strategy. More and more colleagues from portfolio management approach us with ESG-related questions. I’d like to see them go directly into Scaler to explore the data themselves. That’s the next step.
Data Quality and Trust
Luc: You’ve mentioned control and transparency. How has Scaler affected data quality?
Rudy: It’s improved significantly. Because Scaler structures the data according to clear rules, all assumptions have to be explicit. That means our interpretation of the GRESB guidelines is now fully aligned with those of our industry peers. The data has become more reliable and comparable—and that gives us confidence.
Frankly, I sleep better now because there are fewer last-minute issues. We know exactly where we stand and that our data is solid when we submit.
Insights and Visualization
Luc: Altera gathers data from many sources—energy providers, financial systems, certifications. Has consolidating that data in Scaler made a difference?
Rudy: Absolutely. In the past, we worked with huge spreadsheets, which made it difficult to identify outliers or inconsistencies. With Scaler’s dashboards, it’s easy to see where an asset’s energy use is off the charts, and then drill down to find out whether it’s due to a tenant, a shared system, or something technical. That’s a major step forward in efficiency and understanding.
The Value of Partnership
Luc: You’ve worked closely with our Customer Success team, especially Jordy. How has that experience been?
Rudy: Excellent. I thought onboarding support would last a few months, but even today, whenever we have questions, Jordy is there to help. That kind of ongoing support really exceeds expectations—it makes Scaler feel like a true partner, not just a platform.
Continuous Development and the Role of AI
Luc: We’ve recently launched some of our new AI features. How do you see them contributing?
Rudy: What I like about Scaler is that you keep evolving based on client feedback. For example, we use the Net Zero Carbon Roadmaps as a central part of our ESG strategy—they guide our decisions on acquisitions, capex, and disposals.
The new AI assistant will make the platform even more powerful. It will allow colleagues without an ESG background to ask questions directly in the platform and get meaningful answers. That will help sustainability thinking spread further within the organization.
Looking Ahead
Rudy: GRESB remains an important benchmark for us—it shows where we stand versus our peers. But our long-term goal is a net-zero, climate-resilient portfolio that also delivers social impact. In that sense, Scaler’s features—like pathways and data quality checks—are far more important than the score itself.
Luc: That’s exactly how we see it too. Thanks, Rudy. It’s great to hear how Scaler supports your ESG journey. Congratulations again on your results, and we look forward to continuing our partnership.
Rudy: Likewise. Thanks, Luc and the Scaler team.
