Local Climate Conditions

Boston's climate zone 5A represents a humid cold climate with significant heating requirements. With design temperatures ranging from 9°F in winter to 82°F in summer (a 73°F range), and humidity levels around 74%, the area creates specific HVAC challenges. Local wind patterns include atlantic coast marine influences with urban heat island effects, which affects building pressure relationships and equipment performance. The urban heat island effect in Boston 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.
