Abstract: Various embodiments described herein provide systems and methods that utilize radiant energy to adjust an interior occupant space temperature of an interior occupant space in a building structure. In a building structure comprising building components (e.g., wall, ceiling, floor, roof, etc.) that form the interior occupant space, a system may comprise an adjacent volume formed adjacent to an interior occupant space, of the building structure, using at least one of the building components. The adjacent volume may have an adjacent-volume temperature, may be substantially air sealed from the interior occupant space, and may share a boundary with the interior occupant space. The system may further comprise a thermal conditioning module coupled to the adjacent volume, where the thermal conditioning module is capable of adjusting the adjacent-volume temperature within the adjacent volume.
