Wait: What about concrete's high embodied carbon? Because new mix designs on the very near horizon will drastically reduce concrete's embodied carbon, NRG Block can be your complete low embodied carbon and low operating carbon solution. NRG Block's patented technology won the New York State Governor's Award for Energy Excellence for one reason: It works. As designers, you know the first rule of energy efficient design: Lower the building energy load through passive means. NRG's interior uses its high heat capacity to store a lot of energy. NRG's continuous insulation holds more energy in your building, and keeps Mother Nature out. NRG's exceptionally long thermal lag time enables demand shifting of all-electric HVAC systems to loading during periods of off-peak times and rates. NRG's wide variety of textures and colors gives you flexibility to design beautiful architectural finishes. Most important: People who live in NRG homes deserve what NRG can deliver: exceptionally comfortable, quiet, attractive, safe, secure, and low-maintenance homes. Please feel free to call me or e-mail me anytime to talk about your project. I ALWAYS return calls and e-mails within one business day. Thanks! Marty Walters, General Manager, NRG Block.
