Resumo: Given the current issues surrounding the environmental control in museums, particularly revolving around hygrothermal conditions of the internal microclimate, it is important to gain perspective by looking into the past and asserting how it shaped present circumstances on defining climate control strategies. Developments witnessed in science and technology over the past century attest to new approaches and dynamic methodologies that seek to cut energy costs and move from stringent targets to more flexible specifications, opting for simpler and passive measures that intend to be more sustainable. However, differing views exist on these pertaining issues, which accounts for disparities in operating methods and applied standards all over the world that further amplifies the discussion. Tourism can be seen be seen as one of the foremost agents for cultural exchange as well as a major vehicle in facilitating the preservation of cultural heritage with the allocation of resources for its maintenance. However, this relationship between tourism and Heritage Places can often be seen as conflicting in nature, by the fact that it can both lead to opportunities as well as potential complications. Visitors in museum buildings have therefore an impact in the preservation of cultural heritage, given that they influence the internal climate, particularly in terms of hygrothermal conditions, which could possibly induce new concerns as well as hinder their sustainable management. For the present study, an account on the level of climate control strategies used throughout the past century was performed through an exhaustive literature review along with an evaluation of its impact on the sustainability of cultural heritage as well as an analysis of the influence of tourism on its conservation. Therefore, the current work evaluates the impact that tourism, specifically if practiced in an unsustainable way, may infer to the overall preservation of artefacts, mainly on the prediction of mechanical, biological and chemical damage risks. With the aid of a simulation software – EnergyPlus – a model of a generic room from the National Museum of Ancient Art in Lisbon (Portugal) (NMAA) was generated and virtually placed for each district of Portugal, varying also the number in visitors per hour, aiming to estimate – from a risk-based approach – the influence this concerning topic in today’s society has on the internal climate and ultimately the preservation of the artefacts being displayed. In terms of risk assessment, the results show that each increase in occupancy aggravates the potential for damage in each of the considered cases. A geographical distribution of risk is also evidenced, presented in maps, which indicates certain regions where risk is higher than others.
