Passive solar popular apartments in Israel: an evaluation using a simple linear model

A two-equation linear model for passive solar evaluation is used to evaluate direct gain passive solar methods suitable for typical Israeli apartments in three climatic zones in Israel. It is shown that very high savings can be obtained, especially in the Jerusalem area, which is characterized by low temperatures during the winter and comfortable temperatures during the summer.
