Passive airflow comfort control

This student design project carried out for Steve Basford from Grant Instruments.

Original design brief:

The student workstation area in the Gates Building is subject to substantial variations in temperature and humidity. Your task is to design an environmental control system that will monitor and predict changing comfort levels. This should be done sufficiently accurately that corrective action can be taken before conditions become too extreme for passive airflow modifications to be effective. You will use a Squirrel environmental datalogger, with sensors to record current environmental conditions and count the number of people entering and leaving. Based on your recordings of the effects of occupancy and incident sunlight, you should develop a predictive model that will then be used to regulate conditions by managing airflow (opening and closing the external doors) on the final project demonstration day.
