Desert Architecture – Characteristics, Materials and Examples for Arid Climate

Desert architecture is a field that uses innovative design concepts to address the unique issues that arid places provide. From the rocky deserts of the Southwest to the scorching, dry deserts of the Middle East, buildings that are not only durable and practical but also seamlessly blend into the surrounding environment need to be built while taking into consideration factors such as extreme temperatures, a scarcity of water, high winds, and architecture that blends in with the surrounding landscape. The result is a rich history of innovative solutions that balance functionality, sustainability, and aesthetic beauty.

One defining element of desert architecture is its emphasis on sustainability. With limited resources, creativity in the material and technical choices in order to decrease energy use and waste is a must. Many desert structures employ passive solar design techniques, which use the sun’s natural heat and light to regulate interior temperature. Desert architecture requires careful consideration of several factors unique to arid environments.

Factors to consider

• Temperature: Desert temperatures vary greatly, so buildings that can regulate temperature while also providing shade should be developed.
• Water scarcity: Water is a key resource in many arid areas that must be carefully safeguarded and maintained.
• Wind: Strong winds are common in desert regions, necessitating the building of structures capable of withstanding high wind speeds and sandstorms.
• Sun exposure: Solar shading devices and UV-resistant materials must be used since the intense sun exposure in deserts could be harmful to individuals and detrimental to building components.
• Cultural context: Local customs, traditions, and construction materials should be taken into consideration because desert locations frequently have a rich cultural heritage.

Construction materials must be carefully chosen while designing for the severe desert environment. Due to the environment, construction materials must be strong and heat-resistant or they would rot and be destroyed. By decreasing wind and sun damage, protective coatings and finishes can extend the life of building components.

Some materials used in arid environments include:

Adobe

• A sand, clay, and water combination is molded into blocks and sun-dried.
• Renowned for its thermal mass, which helps control indoor temperature.
• Capability to tolerate high winds common in dry environments.

Stone

• A popular and long-lasting construction material found across the desert.
• Since it can be cut or put in a variety of ways, it is a versatile building material.
• It can tolerate severe winds, soaring temperatures, and fire.

Concrete

• Made from cement, sand, and crushed stone or gravel.
• Strong and long-lasting, offers great fire and wind resistance.
• It is a versatile material for desert building since it can be shaped and finished in a variety of ways.

Rammed earth

• A technique for building that involves packing soil into walls.
• Good thermal mass and insulation qualities.
• Offer a distinct, natural look and are fire-resistant.

Straw-bales

• Bales are used as insulation between a structural frame in a construction technique called straw baling.
• Energy-efficient and offer great heat and cold insulation.
• Affordable and simple to use.

The Kaust University Campus

Architect: HOK

Year: 2009

Location: Thuwal, Saudi Arabia

• The campus was planned to take use of natural sunlight, ventilation, and shade, eliminating the need for mechanical equipment.
• Buildings are positioned to take advantage of prevailing winds, allowing natural circulation to cool and ventilate the interior areas.
• Deep overhangs and perforated screens are two more types of shade structures used on campuses to give shelter from the sun and prevent heat absorption.
• A saltwater cooling system, which uses nearby Red Sea seawater to keep the buildings cool, was also included in the design.
• The buildings were constructed using local materials such as sandstone, limestone, and concrete.

The Desert Courtyard House

Architect: Wendell Burnette Architects

Year: 2015

Location: Scottsdale, Arizona, USA

• The courtyard acts as a focal gathering space and provides cover from the harsh Arizona heat.
• The house features large overhangs that provide shade to the outdoor spaces, reducing heat gain.
• The rusty steel utilised in the house’s outside cladding connects the structure to the arid surroundings.
• Among the sustainable components are a rainwater harvesting system that collects and stores rainwater for landscape irrigation and a solar panel system that generates renewable electricity for the home.
• The house was constructed using locally sourced materials such as rusted steel, board-formed concrete, and rammed earth.

The Oman Botanic Garden

Architect: Arup

Year: Ongoing construction, scheduled to open in 2022

Location: Al Khoud, Oman

• The design incorporates a range of sustainable strategies, such as water harvesting, wastewater treatment, and the use of renewable energy sources.
• One of the key features of the garden is its use of natural ventilation, which reduces the need for mechanical cooling systems.
• The buildings are constructed using locally sourced materials such as limestone, which helps to regulate the indoor temperature, keeping the interior cool and comfortable.
• The garden’s landscape design emphasizes the use of native and drought-resistant plant species, creating an ecosystem that is in harmony with the surrounding desert environment.
• The garden features a range of materials, including local stone, timber, and rammed earth. The design also incorporates a range of sustainable materials such as recycled plastic and reclaimed wood.

Techniques for desert architectural design should take into account the region’s unique climatic and environmental factors. Passive cooling systems, water-saving strategies, and the use of appropriate materials that can withstand harsh desert temperatures should all be significant design concepts.

• Proper orientation, shading devices, thermal mass, natural ventilation, insulation, and courtyards are all examples of passive design solutions for desert architecture.
• These solutions can aid in the regulation of interior temperatures and the reduction of the requirement for mechanical cooling systems.
• Materials that are long-lasting, heat-resistant, and resistant to sandstorms and other harsh weather conditions must also be chosen carefully.
• Rainwater collection, greywater recycling, drought-resistant plant species, xeriscaping, water-efficient fixtures, and permeable surfaces are all examples of water-efficient desert design methods.
• These measures can assist to reduce water use and demand on freshwater resources.

Passive design strategies, water-saving techniques, the use of renewable energy sources, the selection of sustainable materials, and the implementation of green building practises should all be considered as sustainable features for desert architecture. To answer to the specific needs of desert climates, these design ideas may be used to produce sustainable, energy-efficient, and aesthetically pleasing desert living environment structures.
