Thermal energy storage systems in buildings can store cooling/heating energy during non-peak load hours or when renewable energy sources are available for later use when demanded. Using the building envelope as a thermal battery can help to shave the peak load, reduce the burden in electric grids, and enhance the occupant''s
Masonry concrete walls are studied for energy storage and losses in cold weather. •. Energy storage is a primary function of the product of density and specific heat capacity. •. Energy loss is first dominated by thermal conductivity and diffusivity. •. Wall WS1 can store 92 % of the heat transfer over 24 h. •.
