In the world of green building, there is a common myth: Sustainability is for the new; complexity is for the old.

For the Sheraton Saigon Grand Opera Hotel, an icon of Ho Chi Minh City for over two decades, the challenge was clear.
The hotel had tried for LEED certification twice before. Each time, the verdict was the same: “Impossible”. Between its 20-year-old HVAC system, high water consumption, and decades of renovations that didn’t match the original blueprints, the mountain seemed too steep to climb.
That is where the story changed.
Seeing potential where others saw limits
When TERAO was brought in, we didn’t look at the age of the building – we looked at its potential.
We knew that behind the “impossible” labels lay a high-performing engine that just needed the right tuning.
This journey wasn’t about a massive, expensive renovation. It was about technical precision and daily intentionality.
Quiet Work, Measurable Change

Terao experts went into the heart of the hotel’s operations. We worked alongside the facility team to analyze the systems and identify exact measuring locations for fresh air. We analyzed the flow rates in showers and kitchens, optimizing fixtures without a single guest noticing a difference in their luxury experience.
A deeper understanding of how the building performs
Cooling systems refined.
Operating schedules fine-tuned.
Water fixtures optimized.
Waste is tracked and reduced consistently
Small Improvements, Big Impacts
For the guests, nothing feels different.
The comfort is the same. The luxury is familiar.
But behind the scenes, the building works smarter:
⚡ Energy: Now performing in the top 31% of hotels globally.
♻️ Circular Economy: Achieved a waste diversion rate of over 50%.
🌿 Superior Air Quality: Average CO2 levels below 700ppm (typically around 640ppm), ensuring a healthy and productive environment for guests and staff.
😊Human Experience: A 95% satisfaction rate, proving that sustainability enhances luxury.
These are not one-time results; this is how the hotel runs — every single day.
