KintaTair focuses on scenario-driven deployments: small retail stores with variable customer flows, manufacturing workshops with intermittent particulate spikes, and multi-zone offices with uneven occupancy. Each deployment begins with a short baseline campaign — sensors log temperature, relative humidity, CO2 and particulate levels for two weeks. Using those logs, our team builds a short scenario library that includes typical occupancy peaks, cleaning schedules and local weather patterns. From there we simulate ventilations and control strategies, then deploy staged changes over a six-week period, measuring air quality improvements, energy delta and maintenance events. Practical examples: a boutique retailer reduced peak-day ventilation load by 22% through occupancy-triggered damper control; a light-manufacturing unit moved to predictive filter replacement, cutting unscheduled maintenance by 60%. These case results help site managers pick conservative, low-disruption measures first and scale interventions as confidence grows.
