Lessons Learned – The ESG Journey So Far at Hoyo Tech

As we near the final stretch of implementing ESG across Hoyo Tech’s offices in Skopje and Struga, it’s time to step back and reflect. ESG transformation is not just about installing smart systems — it’s about how those systems perform, evolve, and support people in the real world.

This article shares what we’ve learned on the ground: the wins, the unexpected challenges, and how our approach changed as our technology matured. It’s a story of iteration — driven by data, feedback, and commitment to purpose.

✅ What Worked Well

🔋 Energy Intelligence Delivered Results

• Solar + battery system in Struga now covers ~80% of daily energy needs on sunny days.
• Real-time load management reduced peak-hour grid draw by more than 65%.
• Adaptive automation decreased idle-time consumption by 18% in Skopje.

🌬️ Comfort Is Measurable and It Improved

• Implementing zone-based climate and lighting increased comfort ratings by 24%.
• User override requests dropped, signaling improved alignment between AI and human preference.
• Air quality compliance was above 95% in both offices, even during high occupancy.

📊 ESG Monitoring Made Governance Real

• Internal dashboards brought ESG out of the boardroom and into daily operations.
• Monthly KPI reviews helped teams proactively solve issues before they became complaints.
• Executive visibility into ESG metrics led to smarter procurement and planning decisions.

🧩 Surprises & Challenges

1. Too Much Data, Not Enough Context
   ➡️ Early in the rollout, Genera had access to a massive volume of sensor data — but lacked behavioral insight.
   ➡️ Solution: we redesigned the Initial Vector (IV) for Genera to include context on device purpose, zone function, and occupancy behavior.
2. Learning vs. Privacy
   ➡️ Behavioral learning by Genera had to balance efficiency with ethical boundaries.
   ➡️ Employees voiced concerns about passive pattern recognition, leading to the introduction of opt-in learning and user review prompts before changes were applied.
3. One Size Doesn’t Fit All
   ➡️ Automation that worked perfectly in Skopje sometimes failed in Struga due to layout and sun orientation.
   ➡️ Our biggest takeaway: ESG automation must be local and adaptive, not just templated.
4. The Human Element is the Hardest to Automate
   ➡️ Comfort is subjective. What feels right for one person may not for another.
   ➡️ Manual overrides remain essential — not as a flaw in the system, but as a safety valve for trust.

🔁 How We Evolved

• Introduced zonal behavioral modeling instead of building-wide assumptions
• Created persona-based AI settings (e.g., “Deep Focus”, “Team Sync”, “Energy Saver”)
• Added visual indicators in dashboards for environmental quality, so users could act even before AI did
• Built a feedback loop between user sentiment and ESG scoring metrics

📈 Impact Snapshot

Our Conclusion: ESG Is a Process, Not a Product

It’s tempting to think ESG success is about tech deployment — but in reality, it’s about evolution. What began as an ESG checklist is now a living framework woven into our operations, culture, and user experience.

We’re proud of the progress. But we’re even more excited for what comes next.

What’s Next in the Series…

In the final article, we’ll outline how we’re scaling ESG into the Hoyo Home platform — bringing everything we’ve built for our internal offices to homes, residential buildings, and partner ecosystems.
