Croniment Corporation's U.S. Headquarters

Cronimet National Headquarters

Cronimet Corporations's U.S. headquarters,  a 13,265 square foot office building in Aliquippa, PA.  Petrus  Engineering and Ken Shiderly Construction teamed together for a complete  turn-key project.  The building is an example of  spacious and functional architecture that was designed with low  operating costs in mind.  The exterior walls were constructed using ICF technology,  with a striking split-faced masonry facade, which gives an effective  R-value of 43 and the solidness that only reinforced concrete walls can  give.  The HVAC is a state-of-the-art VRF (variable refrigerant flow)  system that is so efficient that for much of the year they are cooling  some of the zones in the buildinng by heating other zones (there are 29  zones in the building!).  The entire interior space is lit with highly  efficient and decorative LED lighting . . . giving both a natural and comfortable light as well as a very real power savings.
