Esperanza Base in Antarctica
A Building System that meets all needs, even in the most critical conditions.
Located at a latitude of 63°24‘ S and a longitude of 56°59’ W on a rocky surface at 25 meters high and 30 meters from the coastline, the Esperanza Base is located in Hope Bay, Trinity Peninsula, the northernmost part of the Antarctic Peninsula.
The structure was inaugurated in 1952 as a permanent base, and it now consists of 43 buildings for a total covered area of 374,400 sqm. It accommodates up to 90 people during the summer which fall to 55 in the winter season. In addition, around 1,100 tourists visit the structure each year during the austral summer.
In 1995, the first experimental work carried out with the Emmedue Advanced Building System in Antarctica was realized for the expansion of the Esperanza Research Base, managed by the Argentine Army. In the following years, the Base was further expanded reaching 6 residential units, also built with the Emmedue Building System.
possible with traditional systems. In fact, with the Emmedue System, it is possible to have a 40% saving on the timing, which allowed to realize the required structures during the short period that characterizes the Antarctic summer (December - January), before the soil was covered again by ice and snow, and before darkness fell on Antarctica again. The speed of application of the System is guaranteed by the easy manoeuvrability and ease of assembly of the Emmedue Panel, even under the most difficult operating conditions.
System has proved to be a winning choice as it
allows constructing buildings that last over time and do not require maintenance. In fact, the buildings made with the Emmedue System are made of reinforced concrete and EPS panels, materials that are able to withstand the harsh climatic conditions of Antarctica, unlike metal structures, material with which the remaining units are made, which tend to corrode quickly due to phenomena such as humidity, infiltrations, thermal changes; therefore, these require periodic and expensive maintenance interventions, and often even the complete replacement of the entire unit.
The walls of the units in question, were realized with the PDM150 Double Panel with 7 cm thick slabs, thus obtaining a final wall thickness of 34 cm that guarantees a transmittance of 0.219 W/m²K. The floors were made with the PSS120 Floor Panel, which allows to obtain a thermal transmittance of 0.3 W/m²K.
In the area, winds can reach 200 km/h, which is why the decision to adopt the Emmedue System has once again proved to be appropriate. In fact, constructions made with the Emmedue Advanced Building System in areas with high cyclonic risk, where winds can reach even higher speeds, have shown their ability to resist the passage of the most powerful gusts of wind, also confirmed by tests carried out in renowned laboratories internationally recognized.
