Abstract: Systems and methods of environmental parameter determination are provided. A system can include a data processing system to obtain sensor data, apply a data normalization operation to the sensor data to generate a normalized data set for storage in a database, obtain, from the database, the normalized data set to generate at least a first cognitive index and a second cognitive index, each of the first cognitive index and the second cognitive index, compare each of the first cognitive index and the second cognitive index with a threshold, generate, based on the first cognitive index and the second cognitive index, a unified cognitive index for the indoor space, generate, responsive to the unified cognitive index, a digital output that corresponds to the unified cognitive index; and provide, from the data processing system, the digital output to a client computing device for display by the client computing device.
