At Monde Nissin's 10,000 m² warehouse in Laguna, eight Big Ass Fans HVLS units keep the production floor comfortable — with an estimated saving of more than PHP 400,000 a year, and payback in about 15 months, compared with cooling the same floor using many smaller fans. The savings below are estimates based on that multiple-small-fan alternative, not measured utility figures, and every building is different.
The facility
Monde Nissin operates a 10,000 m² production and storage warehouse in Laguna with high ceilings and an open floor plan. Like many large industrial buildings in the Philippines, the tall, open volume made it difficult to keep the working level comfortable during the hot months, and the space carried a significant cooling and electricity load.
The challenge
The plant needed to keep a large, open, high-ceiling production floor comfortable through the hot months without air-conditioning the whole volume. The usual way to move air across a floor this size is to install many smaller fans — but that means a lot of units drawing power continuously, with uneven airflow, more noise, and hot and cold spots from one zone to the next.
The solution
Philippine GeoGreen specified eight Big Ass Fans HVLS units sized for the building's coverage and circulation needs. High-volume, low-speed fans move large columns of air slowly across a wide diameter, so a small number of correctly sized units can cover a big open floor. The eight fans were positioned to overlap their coverage, break up stagnant air, and create a steady, gentle airflow across the whole production area rather than isolated pockets of cooling.
The results
The eight HVLS fans cover the floor with a steady, even breeze from far fewer units than a small-fan approach would need. The table below summarizes the estimated outcomes, benchmarked against cooling the same floor with multiple smaller fans.
| Metric | Estimated result vs. multiple smaller fans |
|---|---|
| Electricity use | ~40% lower (estimated) |
| Annual savings | PHP 400,000+ (estimated) |
| Payback period | ~15 months (estimated) |
| Worker comfort & temperature consistency | Improved |

Why it worked
This project suited HVLS fans well: a large, open, high-ceiling space where the practical alternative is a floor full of smaller fans. One correctly sized HVLS fan replaces many small ones and runs on a single efficient motor, so it covers the floor evenly while drawing less total power — which is where the estimated saving comes from.
