Smarter Fresh Air for an Occupied Bank Branch
One-Line Summary:
FLO₂ helped an occupied bank branch in Chennai improve indoor freshness, support occupant comfort, and reduce avoidable fresh air energy load.
Project Snapshot:
| Parameter | Details |
| Client / Project Reference | Federal Bank – Anna Salai |
| Sector | Banking |
| Location | Chennai |
| Building Type | Occupied commercial bank branch |
| Conditioned Area | Approx. 1,180 sq. ft |
| Climate Context | Hot and humid |
| FLO₂ Intervention | Smart fresh air automation |
| Energy Impact | Approx. 17% expected saving compared to constant fresh air supply |
| Occupant Benefit | Fresher air, reduced stuffiness, and a more comfortable working environment |
Project Highlight:
Fast freshness recovery in a compact, live banking environment — without adding continuous HVAC load. This project is a strong example of how FLO₂ works in compact commercial spaces where occupancy changes through the day, but comfort and continuity cannot be compromised. The branch needed fresher air, but not at the cost of running fresh air continuously in Chennai’s climate. FLO₂ helped the space recover freshness within approximately 30 minutes during active response, while reducing avoidable cooling load.
The Context:
Bank branches are busy, enclosed environments. Staff spend long hours indoors, while visitors move in and out through the day. In such spaces, stale air is not just a technical issue. It affects how people experience the branch — whether the space feels fresh, comfortable, and alert, or closed and heavy by afternoon. For this branch, the challenge was to improve indoor freshness within practical retrofit limits, without putting additional pressure on the existing HVAC system.
The FLO₂ Intervention:
FLO₂ was introduced as a smart fresh air automation layer for the existing air-conditioned space.
The system allowed fresh air to respond to the needs of the space rather than operate as a fixed, always-on load. This helped the branch improve indoor freshness during occupied hours while avoiding unnecessary outdoor air intake during low-demand periods. The intervention was designed for a live banking environment, where installation disruption, comfort, and reliability were all important.
What Changed:
Before FLO₂, the indoor environment showed clear signs of stale air build-up during occupied hours.
After FLO₂, the space became more responsive. Freshness recovery was observed within approximately 30 minutes during active response, while indoor comfort conditions remained stable.
The result was better-managed fresh air: enough to support occupant well-being, but not so much that it created avoidable energy waste.
Impact Delivered:
| Area | Result |
| Energy Efficiency | Approx. 17% expected saving compared to constant fresh air supply |
| Freshness Recovery | Recovery observed within approx. 30 minutes during active response |
| Indoor Experience | Reduced stuffiness and improved freshness during working hours |
| Comfort | Temperature and humidity remained stable during operation |
| Productivity Link | Fresher air supports alertness, comfort, and a better work environment |
| Retrofit Fit | Suitable for a compact, operational bank branch |
Project Outcome:
For this branch, FLO₂ delivered the balance most occupied commercial spaces need: fresher indoor air, stable comfort, and lower avoidable HVAC energy load. The project shows how a compact branch can improve the everyday indoor experience without depending on continuous fresh air operation.
