Puig Tower office building

This office building consists of three underground floors and twenty-two storeys above ground at Plaza de Europa, 46-48, Hospitalet de Llobregat (Barcelona province).
The work involved the installation of air conditioning, ventilation, centralised control, sanitation and plumbing, natural gas, fire-fighting facilities, solar thermal energy and filtering systems.
The air-conditioning equipment is based on a VRV direct-expansion facility using outdoor water-condensing heat recovery units on each storey. Adiabatic cooling towers, boilers and all associated pumps were installed on the 22nd floor.
The building has received a LEED® gold certification.
