Surplus solar thermal energy is stored inside the ICF wall, which has a high thermal capacity and mass and is integrated into the building envelope. The ICF wall and solar thermal collectors are coupled with a water-to-water heat pump to meet building space heating load and domestic hot water demand.
Thermal storage wall combines the functions of solar collector and storage into a single unit. Heat is transferred from the wall to the room air and to the air between glazing and wall, by radiation and natural convection. Reducing indoor air temperature swings is one of its principal functions (Fig. 6).
The present study aims to propose an innovative building-integrated solar thermal storage method using insulated concrete form (ICF) foundation walls for residential buildings in cold climates such as that of Canada.
Approximately 15–20% of the floor area, which emits heat, should be dedicated to the thermal storage area. To derive more instantaneous heat benefit, air can be circulated from the construction through the air gap among glazing and wall, and back into the room.
Thermal energy storage (TES) technologies have proven to be effective in storing surplus energy and delivering it when renewable sources cannot meet demand. TES dramatically enhances the reliability and efficiency of renewable energy systems.
