Adobe is an especially suitable material to use for building houses in desert environments. Because adobe conducts heat very slowly, adobe houses maintain a pleasant, constant temperature. In the desert, adobe buildings remain cool during the heat of the day but retain the warmth of the sun during the cool evenings. Ideally, a material used for building houses in desert environments should enable those houses to maintain a pleasant, constant temperature.
Adobe is an ideal material for building in desert environments. It conducts heat very slowly. As a result, a house built of adobe retains the warmth of the desert sun during the cool evenings and then remains cool during the heat of the day, thereby helping to maintain a pleasant temperature. In contrast, houses built of other commonly used building materials, which conduct heat more rapidly, grow hot during the day and cold at night.
