NRG Block can create affordable zero energy-ready buildings. NRG's truly continuous insulation (zero thermal bridges) optimizes concrete's thermal storage capacity. NRG's concrete interior absorbs and stores energy. The middle layer of continuous insulation holds the energy in the building and prevents exterior influence. NRG's concrete exterior adds an attractive, secure, fire-safe, bulletproof, and low-maintenance architectural finish. NRG Block enables demand shifting of electric HVAC to periods of off-peak rates. Over 300 buildings have been created in the last 25 years. Low embodied-carbon concrete options coming online will complement the lifetime low operating-carbon performance that NRG already delivers.
