Home Case Studies Fresh Air Optimization for a High-Rise Office
FLO₂ helped a high-rise office in Pune improve indoor freshness and reduce avoidable ventilation energy by making fresh air supply more responsive to actual space use.

Fresh air optimization for an office where occupancy changes from zone to zone through the day. This project is strongest as a modern workplace story. The office had different types of spaces being used in different ways — workstations, cabins, meeting rooms, and shared areas. A fixed fresh air approach would have treated the entire floor the same, even though not every space needed the same level of ventilation at the same time. FLO₂ helped the office move towards a smarter use-based fresh air strategy, delivering approx. 12% energy saving compared to constant fresh air operation.
High-rise offices often have a mix of steady and intermittent occupancy. A meeting room may be full for an hour and empty after that. A cabin may be occupied only part of the day. Shared zones may experience short periods of high use. When fresh air is supplied in a fixed manner, the building can end up over-ventilating some spaces and under-serving others. This affects both comfort and energy efficiency.
The requirement was to improve indoor freshness in a way that matched how the office was actually used.
FLO₂ was introduced to make fresh air supply more responsive to real indoor conditions. The system helped the office move away from a one-size-fits-all ventilation approach and towards a more intelligent operating model. Fresh air was better aligned with space use, helping support both air quality and energy performance. This made the solution well-suited for an operational high-rise office where employee comfort, continuity, and energy efficiency all mattered.
Before FLO₂, the office showed a steady build-up of stale air through the working day.
After the intervention, indoor freshness was brought into a more controlled operating range. The office was able to maintain better air quality during occupied hours while reducing the energy penalty associated with continuous fresh air supply. The improvement was especially relevant for meeting rooms and shared spaces, where occupancy changes quickly.
| Area | Result |
| Energy Efficiency | Approx. 12% saving compared to constant fresh air operation |
| Occupancy Fit | Fresh air use better aligned with changing office patterns |
| Indoor Experience | Improved freshness in active work and meeting spaces |
| Comfort | Better balance between fresh air and thermal comfort |
| Productivity Link | Fresher indoor air supports focus, alertness, and well-being |
| Operational Fit | Practical for a live high-rise office floor |
This project demonstrates how FLO₂ can help office spaces respond better to the way people actually use them. By making fresh air responsive rather than fixed, the office improved indoor freshness, supported occupant comfort, and reduced avoidable HVAC energy load.
