    Hot Dry Climate: Physiological Objectives

    Uploaded by

    Cebo Dharu
    This document describes the characteristics of a hot dry climate and strategies for building design in these climates. Key points include: - The climate is very hot and dry during the day with low humidity and rainfall. Nights can be cooler. - Buildings should be enclosed and inward-looking to protect from heat, sun, and dust. Larger walls should face north and south. - Shading is extremely important. Roofs, walls, and outdoor spaces should be shaded through overhangs, trees, or surrounding buildings to reduce heat gain.

    HOT DRY CLIMATE

    • Characterized by very hot, dry air and dry


    ground.
    • Day time air temperature ranges from 27-49
    degree Celsius, night
    time temperature may fall to 22 degrees.
    • Humidity is moderate to low.
    • Water level is usually low.
    • Low rainfall, as low as 500mm/year.
    • There is little or no cloud cover which permits
    direct radiation to heat
    the ground during day and ground to lose heat
    during night.
    • Summers are subjected to hot, dusty winds.
    • This region is usually flat, sandy, rocky ground
    with spares
    vegetation of cacti thorny bushes.
    • Parts of Rajasthan, Gujarat and Madhya
    Pradesh fall under it.

    PHYSIOLOGICAL
    OBJECTIVES
    • Problem is of protection: reduce the radiation
    from the sun, ground
    and the nearby buildings.
    • Breeze can be used after it has been cooled and
    filtered.
    • The building objective is to minimize heat gain
    during day and heat
    loss during the night.
    • Lack of humidity/Evaporation is the climatic relief.
    • Low humidity leads to high rate of evaporation
    and this can be an
    advantage: Desert coolers.

    FORM AND
    PLANNING
    • Buildings and the external living spaces are to be
    protected from the
    hostile conditions: Solar radiation, hot dusty winds,
    etc.
    • Enclosed, compact and inward looking building
    is the most
    suitable.
    • Larger dimensions of the building should face
    North and South.
    • Non-habitable rooms like toilets, store room, etc.
    can be used as
    thermal barriers: can be placed on East and West.
    • Roof, walls and outdoor spaces must be
    shaded: Roof
    projections (chajja), shading devices, trees, walls
    of surrounding
    buildings are common examples.
    • Mutual shading: by aligning buildings close to
    each other.
    • Fenestrations (doors and windows) should be
    small.
    • Simple ceiling with ventilated roof is advisable.

    SOME TRADTIONAL
    CASES
    • Examples can be the mud houses in Kano,
    Nigeria or even in Egypt.
    • Roof and heavy walls made of earth, brick or
    stone.
    • The heavy walls provide good thermal and noise
    insulation.
    • Roof and courtyards are used at night for
    sleeping.
    • Windows and doors are small to restrict heat
    and dust.
    • One major example is the haveli of Rajasthan
