Abstract: In some embodiments, apparatuses and methods are provided herein useful for environmental control inside an enclosure including an enclosure, an exhaust fan located in proximity to an outlet of the enclosure, a temperature sensor located proximate the exhaust fan and configured to provide exhaust air temperature data, a first sensor located proximate a supply intake of one of one or more electronic equipment and configured to provide sensor data associated with air that is supplied to the one of the one or more electronic equipment, a fan control unit (FCU), and a power control unit (PCU). The FCU is configured to adjust fan speed of the exhaust fan. The PCU is configured to receive the sensor data from the first sensor; receive the exhaust air temperature data; and provide the fan speed control data to the FCU based on the sensor data and the exhaust air temperature data.
