Abstract Scope |
Heating and cooling buildings is a major source of energy consumption. Ways to store energy in low demand times and use it in peak demand times are needed, especially as renewable energy use become more prevalent. Concrete additive manufacturing (AM) could provide another avenue for thermal storage in buildings. In partnership with the Federal Energy Management Program (FEMP), Oak Ridge National Laboratory (ORNL) has conducted a field validation of thermal energy storage with an active insulation system called the Empower Wall. Concrete AM formwork enabled the use of these technologies. The wall uses electricity in low demand times such as at night when cooling loads are lower to cool the printed concrete formwork and central concrete mass to be used to cool the room at a later time. The Empower Wall was able to reduce energy cost and peak loads on the HVAC system. |
