Energy-intensive building

The diverse and unique industrial and technical heritage of Idrija’s 500-year-old mining history was inscribed on UNESCO World Heritage List in 2012. One of the crucial parts of the mercury mine was the smelting plant, which stopped operating in 1995. Its renovation and renewal was a significant challenge in terms of financing and expertise. The energy renovation of the building was carried out in accordance with the possibilities and specifications of the building, which belongs to the technical cultural heritage. The project comprised the reconstruction and extension of the existing ore separation facility and construction of a new building intended for reception of visitors and hosting a permanent exhibition 'From ore to mercury drops'. Two investment phases were planned - the first one is finished, the second one will focus on the furnace, extraction and packaging of mercury in cylinders. In 2020 the refurbushed Idrija mercury smelting plant won the 2nd prize of the ‘Destination of Sustainable Cultural Tourism’ award under category of industrial heritage.

Envelope performance

    In the reconstructed part of the building, there are concrete frame structures with masonry walls in between. All walls, except in the basement, were additionally thermally insulated with EPS panels on the inside of the building, and a cement spray performed over them.
    The window openings remained the same, windows were replaced with ALU windows with double-layer thermopane glazing.
    The roof is made of reinforced concrete beams, to which a wooden substructure is attached. The asbestos roofing has been replaced with a new suitable corrugated roofing. The roof is thermally insulated with soft mineral wool 25 cm thick, and the inside is lined with OSB panels, which are treated with cement spray over galvanized welded metal mesh.
