Implementing passive solar heating involves using the building’s structure to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. Heat Distribution – Passive solar design allows solar heat to circulate from collection and storage points to different areas of the house. Materials such as concrete, masonry, wallboard, and even water absorb heat during sunlit days and slowly release it as temperatures drop. 56, P < 0. wt qn eu ux ju nb qe tr sm zg
