Casco Antiguo is a historic district declared a World Heritage Site by UNESCO, where restored colonial and republican buildings share streets with boutique hotels, restaurants, offices and homes. As a peninsula surrounded by sea, it adds the salt air of its surroundings to Panama’s humidity.
In many old buildings air conditioning arrived after construction, and the ducts run through small technical spaces and routes that are not obvious. That is why the route is learned before any work, and the access points are agreed with the owner or the management, without opening anything that has not been settled. If the route is not documented, the first report describes it for later visits. The area is about 7 km by road from the Climatiza office, in an approximate calculation.
Data point: At the Tocumen station the mean relative humidity drops to 64.9% in March, the least humid month, and rises to 82.4% in October (ETESA, 1977 to 2010, in Spanish). The EPA recommends keeping indoor air below 60%.
