Local Climate Conditions

Chicago's climate zone 5A represents a humid cold climate with significant heating requirements. With design temperatures ranging from -5°F in winter to 89°F in summer (a 94°F range), and humidity levels around 70%, the area creates specific HVAC challenges. Local wind patterns include lake effect and urban canyon winds, which affects building pressure relationships and equipment performance. The urban heat island effect in Chicago can increase ambient temperatures by 5-10°F, requiring additional cooling capacity in dense areas. Air quality considerations require enhanced filtration systems due to moderate air quality conditions.
