The National Library of Scotland is one of the most important libraries in Europe. The Library holds priceless collections, whose conservation depends on the adequate environmental conditions, checked by using energy efficient systems.


The Library decided to rely on the Carbon Trust to develop a management plan for carbon emissions. One of the main purposes of this project was to exploit the extraordinary efficiency of Turbomiser in order to provide a low cost, low-impact and efficient cooling for archives and reading rooms.


The project concerned the replacement of two former chillers with the 300 kW TMH water cooled Turbomiser units connected to a sophisticated free cooling system providing chilled water to some UTA units in the building.


Although the former refrigeration plant had never been monitored, it has been possible to calculate a reduction of 11.4% in energy consumption, with a sensible saving in costs and carbon emissions.
