Continuous commissioning

75F Dynamic Airflow Balancing (DAB) is a proactive zone control system that remotely monitors and controls conditions in individual spaces for superior comfort and efficiency. Predictive machine learning algorithms optimize heating and cooling capacity by redirecting conditioned air to the spaces that need it most, a strategy which is proven to lower utility costs by up to 45%.

Individual room comfort control

The DAB design is fine grained, so every space gets its own individual temperature control. Building engineers who implement 75F’s DAB technology can expect vastly improved energy efficiency, occupant comfort, and productivity. These advantages are accessible to a wide variety of commercial buildings thanks to a full-stack solution that works out of the box, scalability across a range of central plant equipment and site footprints, and intuitive and user-friendly tuners like zone prioritization for hassle-free operation. 

Energy efficiency that scales

Dynamic Airflow Balancing scales easily from simple RTUs to advanced hybrid AHUs. DAB works out of the box to stage fan speed to airflow requirements in the system based on thermodynamic calculations and continuously redirects air. In a variable air volume system with staged heating or cooling, VFD frequencies are automatically set to best match the required stage. For built-up AHUs with chilled water and/or hot water coils and variable frequency drives, DAB resets temperature at the air handler to an optimum value for load calculations.

Dynamic Airflow Balancing scales easily from simple rooftop units to air handling units with variable-frequency drive fans connected to a central plant.
75F’s wireless sensors, placed in each zone, capture thousands of data points a minute and millions of data points daily on temperature and humidity

Predictive and proactive

75F’s wireless sensors, placed in each zone, capture thousands of data points a minute and millions of data points daily on temperature and humidity. Via a 900 MHz wireless mesh network, these sensors upload to 75F Athena and a dynamic thermal model of your space in the cloud. Athena’s algorithms include a live weather stream and forecast data so 75F can predict optimal control strategies. Each zone is configured for parameters such as size of damper and the min/max damper positions for tracking in the algorithms. After a few days, the 75F technology can very accurately anticipate heat loads and can use that information to predictively and proactively control the temperature and air volume in the zones or offices of a building.
