Why does condensation can still take place today even surrounded by some non-residential buildings?
Answers: Theoretically it shouldn't. Buildings are insulated very very well these days, almost nouns tight. HVAC systems are designed to compensate for that by exchanging the stale air beside fresh air. During winter, moisture may enjoy to be added to the air to be exact circulating throughout the building. The system is supposed to control the amount that is added, but on point adds too much. This will wreak condensation on windows, doors, etc. Your home works surrounded by a similar way if you hold a humidifier mounted on the ductwork at the furnace. There is a humidistat that controls the amount of moisture added. If we don't adjust for changing warmth, we get condensation. Hope this help.
