Wind driven rain louver

A louver assembly for a heating, ventilation, and air conditioning (HVAC) system, the louver assembly comprising:

• a louver blade comprising a first segment and a second segment, wherein the second segment is adjustable, relative to the first segment, between a first position and a second position, the second segment movable between a first position and a second position, wherein the second segment reduces an amount of free area through the louver assembly, and wherein the second segment is increases the amount of free area through the louver assembly in the second position;
• a controller configured to control transition of the second segment between the first position and the section position;
• and
• a sensor communicatively coupled to the controller, wherein the sensor is configured to collect data indicative of an operating parameter of an environment surrounding the louver assembly, and the controller is configured to control transition of the louver blade between the first position and the second position based on the data.

A louver blade for a louver assembly, wherein the louver blade comprises:

• an upstream segment comprising a first extension;
• a downstream segment comprising a second extension and a third extension, wherein the downstream segment is configured to rotate relative to the upstream segment between a first position and a second position;
• and
• a seal disposed within a recess of the second extension, wherein the seal is engages with the first extension of the upstream segment in the first position of the downstream segment,
• wherein the downstream segment reduces an amount of free area through the louver assembly in the first position and increases the amount of free area through the louver assembly in the second position.
