“…For example, adobe construction (clay or mud) has been used as a main construction material for thousands of years for the construction of buildings in most inhabited regions all over the world [32,35,[37][38][39][40][41][42][43][44]. Moreover, some examples of modern buildings built from adobe construction can be found in many countries that have different climatic conditions [41,45,46]. Similarly, many vernacular techniques like courtyards and wind towers (catchers) were applied in modern buildings for passive designs [47].…”

The Role of Vernacular Construction Techniques and Materials for Developing Zero-Energy Homes in Various Desert Climates

2017

Hot desert regions, like Saudi Arabia, are very challenging in terms of building energy consumption. The role of the housing sector in the country is critical as it accounts for half of the total national electricity consumption. It is important to apply sustainable energy concepts in this sector, and the application of Zero-Energy Homes (ZEHs) could be an appropriate option in this regard. In ZEHs, the energy demand needs to be reduced significantly before employing renewable energy, and a way to achieve that is through applying vernacular construction techniques and materials. This study aims to investigate the role of courtyard, mushrabiyah and adobe construction for the development of ZEHs in the five main Saudi climatic zones represented by Dhahran, Guriat, Riyadh, Jeddah and Khamis Mushait. A base house is designed, modelled and compared with measured electricity values. The comparison between the base house and the houses adapted with these techniques and materials is undertaken based on the annual electricity demand and the maximum power demand, and findings reveal that mushrabiyah can reduce them by 4% and 3%, respectively, while adobe can reduce them by 6% and 19%, respectively. Courtyards are found to be not helpful in terms of energy saving.

“…Green building has become a prominent response to addressing climate change [1]. Green building includes earth building, which is a centuries-old building technology [2,3], applied by many people across the globe [4]. Earth building has substantial benefits for sustainability, cost reduction and energy saving.…”

Informal Settlement Upgrading in South Africa: A Preliminary Regenerative Perspective

2019

View full text Add to dashboard Cite

Informal settlement upgrading is commonly practised worldwide, but often in technical ways, paying little attention to the physical environment. Regenerative development provides an ecological response and emphasises human development concerns. In this paper, we adopt a social constructivist approach to investigating the meaning of construction processes and the value of regenerative development in an informal upgrading process in South Africa. We used data from 18 projects and five in-depth interviews. Our findings show how waste can be used in this process, and that regenerative development delivers houses that are better insulated and avoid some of the risks associated with houses constructed by informal settlers. The value of the project lies in the acceptance of eco-building and the development of an attachment to the physical environment. Regenerative development facilitates self-help, which in turn supports the user value of these houses. We found considerable human development linked to regenerative development. Our findings show that, in addition to providing shelter, regenerative development encourages artistry and imagination, gets members of the community to work together, promotes social empowerment, improves physical and mental health, and fosters enjoyment.

“…Each earthen layer has thicknesses of about 10-15 cm. More details about this technique of construction are presented in [1,2]. is material is recently experiencing a renewed interest because of its low embodied energy [3], its recycling ability, and a positive hygrothermal behavior which offers an attractive living comfort [4].…”

Rammed earth (RE) is a construction material which is manufactured by compacting the soil in a formwork, in different layers. Several recent studies have investigated this material. The seismic performance of RE buildings is an important topic which needs to be carefully investigated. The complex numerical model seems a performant approach to investigate the seismic performance of a whole building. To correctly establish the model, the shear parameters of the material, which are the cohesion and the friction angle, should be identified. This paper first presents experimental studies on the shear parameters of RE through the direct shear tests, at two different scales. The differences of the results at different scales are analyzed. Then, the obtained experimental values are used in a numerical model to simulate the shear behavior of RE walls which are loaded by a constant vertical stress and pushed horizontally on the top. From the obtained results, the values for numerical models are recommended.
