Local Climate Conditions

Philadelphia's climate zone 5A represents a humid cold climate with significant heating requirements. With design temperatures ranging from 7°F in winter to 87°F in summer (a 80°F range), and humidity levels around 76%, the area creates specific HVAC challenges. Local wind patterns include mid-atlantic coastal influences with urban heat effects, which affects building pressure relationships and equipment performance. The urban heat island effect in Philadelphia 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.
