Federal Contracts –
Energy Conservation & Infrastructure Improvements

Since 1998, NASCO has implemented tens of millions of square feet of infrastructure improvements and upgrades coast to coast for US Federal Government installations, bases, and facilities. In many, if not most, cases this infrastructure renovation has included comprehensive energy conservation and system efficiency measures such as lighting, building controls, HVAC, geothermal, central heating & cooling plants and renewable energy systems. In addition to our vast experience in infrastructure renovation and upgrades, NASCO has been the GC/CM for many new construction projects. As a rule, these projects have been designed and built to a LEED Silver standard to ensure energy efficiency and sustainability.

In all, NASCO’s infrastructure and energy conservation work has saved US taxpayers millions of dollars in reduced energy costs, while providing facilities that are safer, more secure, healthy, productive and efficient.
