Elisa Rubalcava
Elisa completed her Bachelor's degree in Architecture in Mexico, specializing in the field of heritage conservation. She worked on the conservation of the 16th Century Mexican Monasteries designated by UNESCO before pursuing her postgraduate studies in the Conservation of Monuments and Historic Sites at the Polytechnic University of Catalonia, Spain. Elisa was the conservation architect for the restoration and rehabilitation work at Museo del Acero “Horno 3” (Blast Furnace No.3) in Monterrey Mexico, a national industrial heritage site.
Since 2016, Elisa has worked within the Conservation and Construction Services program area of the Historic Resources Management Branch, responsible for undertaking conservation and environmental management work on nine historic sites owned by the Government of Alberta. Four of these are Industrial heritage sites that preserve historic infrastructure related to natural gas production, coal mining and irrigation farming. Turner Valley Gas Plant, a Provincial Historic Resource of Alberta and National Historic site of Canada is particularly significant as it is located in western Canada’s largest oil field and is considered a birthplace of Alberta’s energy industry, extracting and processing natural gas from 1914 until 1985.
