In the Caribbean, South America and even North America forficaons are a recurrent topic in the field of conservaon of historic buildings. In this typology every architectonical element has historic value, therefore, very few intervenons are allowed, making the conversion of forficaons a very challenging task. In the last two decades in Cuba, there have been examples of refurbishments and conversions of forficaons into museums, some of them with dire consequences for the collecons and the structures. Moreover the accommodaon of modern funcons and the preservaon of the structure heavily rely upon the balance between various environmental parameters of the interior spaces. This study explores the challenges and opportunies of an environmentally driven conservaon approach to the refurbishment of one of Habana’s most iconic XVIII century’s defensive structures, Santo Domingo of Atares’ Castle. The dissertaon illustrates the development of an architectural proposal for the conversion of the castle into a museum and associated energy and environmental strategies. The museum funcon is parcularly demanding due to the rigorous standards for the preservaon of the collecons, convenonally accomplished by mechanical equipment. Recently, however, there has been a major concern in the conservaon scene about energy consumpon and sustainable pracces in historic buildings, with examples worldwide. Therefore, the work aims at idenfying the characteriscs of the exisng climac and environmental condions affecng the interior spaces of the thermally heavyweight fortress, in order to device passive and hybrid strategies for the new funcon. This led to an analysis of the requirements of the collecon in a hot-humid climate in conjuncon with the parameters for human comfort, in order to idenfy to what extent the original condions can be passively modified to adapt the building to the conversion. Finally, with the help of computaonal dynamic simulaons, passive strategies and zoning opons were tested for the achievement of suitable interior environmental condions and energy savings.

In the Caribbean, South America and even North America fortifications are a recurrent topic in the field of conservation of historic buildings. In this typology every architectonical element has historic value, therefore, very few interventions are allowed, making the conversion of fortifications a very challenging task. In the last two decades in Cuba, there have been examples of refurbishments and conversions of fortifications into museums, some of them with dire consequences for the collections and the structures. Moreover the accommodation of modern functions and the preservation of the structure heavily rely upon the balance between various environmental parameters of the interior spaces.
This study explores the challenges and opportunities of an environmentally driven conservation approach to the refurbishment of one of Habana’s most iconic XVIII century’s defensive structures, Santo Domingo of Atares’ Castle. The dissertation illustrates the development of an architectural proposal for the conversion of the castle into a museum and associated energy and environmental strategies. The museum function is particularly demanding due to the rigorous standards for the preservation of the collections, conventionally accomplished by mechanical equipment. Recently, however, there has been a major concern in the conservation scene about energy consumption and sustainable practices in historic buildings, with examples worldwide. Therefore, the work aims at identifying the characteristics of the existing climatic and environmental conditions affecting the interior spaces of the thermally heavyweight fortress, in order to device passive and hybrid strategies for the new function. This led to an analysis of the requirements of the collection in a hot-humid climate in conjunction with the parameters for human comfort, in order to identify to what extent the original conditions can be passively modified to adapt the building to the conversion. Finally, with the help of computational dynamic simulations, passive strategies and zoning options were tested for the achievement of suitable interior environmental conditions and energy savings.

The best natural ventilation strategy was tested against the use of night-time ventilation with an alternative humidifier composed by silica-coated louvers inserted in the covers of the openings in the roof. Both strategies are effective keeping relative humidity below 70%, but the dehumidification achieves lower temperatures.

Da Vinci’s artefacts are wood, leather and fabric objects of different sizes and types of interaxtion and exhibition modes. For its preservation in hot-humid climates it is needed conditions of less than 70% of relative humidity.
