Rammed Earth House in Maun_Botswana

These  photos are from the construction process of a rammed earth house built in Maun, Botswana, by Arch. Paul Marais, researcher from the University of Wales Institute Cardiff in association with the Centre for Alternative Technology in Wales on the study of sustainable technology in southern Africa.

Using soil escavated from the site as well as additional soil from aprox. 80km away (to improve structural aspects but also the aesthetics) this is a beatifully simple but significant example of earth construction as a resilient and universal material / technology.

Ramming the earth was done by hand inside plywood forms, which were reused after ramming for the roof structure.

The earth walls turned out fantastic, and the building respond nice and cool specially in the 35+ tough temperatures common in Maun.

 

" Buildings are energy and they use energy in their daily use. Sustainable Design looks at optimising energy use and harnessing the energy that arrives daily. Buildings have a certain amount of energy used in the process of building them and then they require energy for coolth and warmth, light and dark and suppling water and removing waste.

The energy that goes into building the building, creating it's materials, feeding the artisans and getting it all to the building site, we call the embodied energy.

This is tricky to measure exactly as you can imagine (how much oil and petrol and farmers braai went into that peanut butter that mainly produced a sleepy constructor?) so we use generalised measures and common sense . We know that materials found on site have a low embodied energy so we use natural materials sourced on site where possible. We must also consider the energy use during the buildings lifetime.

This may seem insignificant at first (what's a few heaters compared to ton's of coal used to make concrete) but it can be higher than the embodied energy as it will be over a very long period.

Buildings can be orientated to use the sun's energy for heating and cooling electricity generation and to reduce water and waste energy needs. Another form of energy that we consider in sustainable design is the energy of the occupants of the building.

People have strong cultural and social links to the physical space that they inhabit - sustainable design investigates their needs, wants and desires, creating solutions that fit!"

Secondary school_Gando_Burkina Faso_Francis Kere

Secondary school in Gando with passive ventilation system in Ouagadougou, Burkina Faso by Francis Kere Architecture

'Architect Frances Kere has been building really interesting schools in Burkina Faso for some time. Now he has used rammed earth in one of them, in a creative way.

This school project in one of the world’s poorest countries aims to provide further education to the inhabitants of a rural area. Gando, with a population of 3000, has no secondary education facilities and lies on the southern plains of Burkina Faso, some 200km from the capital Ouagadougou. Diverse design aspects of the project consider the challenging weather conditions where summer temperatures peak at 40°C. 

The natural ventilation cooling effect is enhanced by routing air through underground tubes, planting vegetation, and the use of double-skin roofs and façades to achieve a 5°C thermal reduction. The enhanced indoor comfort and conditions are far more conducive to education.

Energy consumption during construction and operation is reduced to a minimum using only the sun and wind. The collection of scarce rainwater is integrated into the planting concept and is used to irrigate newly-planted trees that are intended to help consolidate previously exploited vegetation.'

Escola secundária em Gando com sistema de ventilação passiva em Ouagadougou, Burkina Faso por Francis Kere

'O Arquitecto Francis Kere tem vindo há já algum tempo a desenvolver projectos e  a construir escolas muito interessantes no Burkina Faso. Neste projecto em particular explora uma vez mais de forma criativa a técnica da taipa.

Num dos países mais pobres do mundo esta escola tem como objetivo garantir serviços educativos complementares aos habitantes de Gando, uma área rural das planícies do sul do Burkina Faso, a cerca de 200 quilómetros da capital Uagadugu, com uma população de 3000 pessoas e sem instalações de ensino secundário.

As condições meteorológicas adversas na região, onde as temperaturas de Verão atingem máximos de 40°C, foram consideradas durante a concepção do projecto.
Por exemplo, o efeito de arrefecimento natural é garantido por um sistema de ventilação que encaminha o ar através de tubos subterrâneos. Este é ainda garantido pela plantação de vegetação e pela utilização de fachadas e coberturas duplas com uma redução média de 5°C. 

Por outro lado o consumo de energia durante a construção e utilização  dos edifícios é reduzido ao mínimo utilizando apenas a energia natural do sol e do vento. A recolha de água das chuvas ainda que escassas é integrada no conceito sustentável de plantação e é utilizado para irrigar as árvores recém-plantadas que se destinam a colaborar na consolidação da vegetação anteriormente integrada.'

Earth Sculptures_Alderney Stones_UK

A new site-specific installation of works by Andy Goldsworthy opened on the island of Alderney, located in the Bailiwick of Guernsey in the English Channel Islands. Alderney Stones consists of an installation of 11 boulders spread across the landscape of Alderney.

Goldsworthy formed each 3-ton boulder from a mold of rammed earth and other materials sourced from the island, such as berries, seeds, old tools and discarded gloves.Set in varying degrees of exposure to the elements, the stones will eventually erode, revealing the elements concealed inside, and ultimately return to the land from which they came.

Rammed Earth in Panyaden School_Tailand

How Rammed Earth Buildings Can Save Energy

By Markus Roselieb

Rammed earth is ideal for hot and dry climates because of its great capacity to store heat. Therefore it is perfect for Chiang Mai during the dry season where we have hot days and cool nights. The heat gets absorbed by the rammed earth walls during the day and is released into the surroundings during the night. In this way, it balances out the temperature of the surrounding area.

In the case of a high moisture content in the environment, rammed earth is very suitable as it has good moisture absorption. The humidity content of the earth when it is dried out is very low. The earth can absorb up to 30 times more water than concrete which means that in the long and heavy rainy season, the rammed earth walls will absorb the moisture of the environment, and balance out the moisture content, providing a mold- and fungus-free space.

Comparing Thermal Performance

The table below compares the thermal performance of classrooms built with two different types of walls.

Source: Earth Architecture in Western China

Red curve = indoor temperature in a rammed earth classroom (like those in Panyaden)

Yellow curve = indoor temperature in a conventional brick and concrete-based classroom

Blue curve = outdoor temperature

It is obvious from the study above that the indoor temperature of the earth classroom is always stable. In summer, it swings only between 21oC and 24oC. In winter, without any energy consumption for heating, it can reach an acceptable indoor comfort.

If you touch earth, concrete, steel and asphalt that are exposed to the sun, you will find that the different materials have different temperatures. The metal will be by far the hottest, followed by asphalt, then concrete (both are still so hot that you cannot walk barefoot on them for more than a few minutes). The earth will, however, be cool.

A concrete building is like an oven in which an air-conditioned interior space is inevitable. On the other hand, rammed earth has an excellent thermal mass because of its high density, and the high specific heat capacity of the soils used in its construction. It can store the heat during the day and release it slowly into the surroundings during the night. This energy-saving feature is one reason why we built our classrooms with this technique.
