The second largest NATO Peace Headquarters in Europe, and probably the largest seismic isolated building in the world, the new NATO JFC Headquarters is a 100,000 sq. meters - 164 million euro complex for the relocation of the former AFSOUTH HQ in Naples, Italy. The complex provides new, effective work space for over 2,500 personnel. Interplan was in charge of the full A/E mission and for preparing the project's Integrated Security Plan. The HQ is comprised of 6 main buildings organized around a public space: Main Complex, Motor Pool, Community Center, Italian Command HQ, Media Center, sports courts and helipad. The Main Complex building is the largest facility on site with 4 above grade floors and a large 2 level underground working areas. The entire structure is isolated at the base by the means of 450 HDRB seismic isolators.
The energy saving and environmental sustainability strategies implemented at the new HQ include a District cooling central plant with an Ice Melt storage system which allows the nightly use of the refrigerators necessary for producing ice and the use of ice during the day to obtain "free" A/C cold fluids. Also a grey water system ensures that rainwater and well waters are collected, treated, and re-used for irrigation, washing and flushing. Natural lighting of the work areas is achieved to the maximum extent, thanks to main corridors configured as multilevel distribution galleries with clearstories on top to introject sunlight into the hearth of the building blocks. These sustainability measures allow for significant energy savings estimated in an overall 30% reduction of the annual O&M costs in comparison to conventional modern office buildings.
