We’ve launched a crowdfunding campaign so you can help us finish building an edu-centre at the Delft ECD

We’ve launched a crowdfunding campaign because we really need your help to finish building the edu-centre in Delft so carers from informal crèches can get training in early childhood development.

We are busy building a passive solar, earth sheltered building out of tyres, cob, compressed earth bricks and glass bottles at the Delft Early Childhood Development (ECD) centre. But, we need your help to finish building it. The building will be an edu-centre so carers from informal crèches can get training in early childhood development.

Visit Thundafund to make your contribution!

Following our involvement with building the Delft Early Childhood Development centre with natural and sustainable building materials we saw the space and need for an adult training centre there so that, amongst other things, carers from informal crèches in Delft and surrounding areas can receive training in early childhood development. It has been widely accepted that the first 1000 days in a child’s life is critical to their, as well as society-at-large’s health and wellbeing. During this period, children’s brains can form 1,000 neural connections every second and these connections are the building blocks of their future. But, we need your help to complete the building…

What we have achieved to so far:

  • Peter McIntosh has raised R120 000 from the Sophia foundation towards materials and has donated three months of his time towards the success of the project.
  • We have provided employment for eight members of the local community during the building process.
  • We have provided a month-long training sustainable building course including for architecture students of CPUT. The course was presented in collaboration with Guy Williams on behalf of international NGO Long Way Home from Guatemala.
  • We have also used provided other learning opportunities for volunteers, architecture interns.

We need to get from here:

How we’ll use your contribution:

With your help we can complete this building… Your contribution will go towards completing the following activities:

  • Planning gum pole purloins to level to install roof sheets
  • Installing IBR roof sheets
  • Complete last two sections of ring beam (shutter/form and pour concrete)
  • Source and make over 2000 more bottle bricks
  • Install bottle bricks in cob above ring beam
  • Cob scratch plaster coat, form coat and final lime plaster coat internally
  • Form and final plaster coat on internal and external bottle walls
  • Level and stamp floor
  • Gravel, newspaper, cob and compressed earth brick floor layers
  • Final layer on floor
  • External plaster finishes on tyre walls and ringbeams
  • Final touches on tyre retaining wall and earth berm
  • Front level ramp and paving threshold
  • Painting fibre board on door-front

With your support we are making a difference… Thank you! 

 

Transition Ethics: The Art of Compromise

This post first appeared on Numundo on 16 February 2016. We are re-posting it here with the permission of  Shayna Gladstone and author Scott Gallant.

To introduce the post, we’d like to share with you why we were so excited to read Scott’s post. Written by Scott Gallant from Rancho Mastatal Sustainability Education Center in Costa Rica, the post is based on his experience teaching the three permaculture ethics during the center’s Permaculture Design Courses, and the realization that a fourth ethic is required in order to facilitate a conversation about compromise.  They filled the gap with the Transition Ethic. Scott quotes Jessi Bloom and Dave Boehnlein, authors of Practical Permaculture, who acknowledge that “the transition ethic says that no one is going from zero to sustainable overnight. Making the transition takes time.” He goes on to say that “We have to meet people where they are at.  We must understand their cultural context.” Continue reading

From the ground up ~ approaches to building a foundation for your natural building

Foundations for conventional building have, to a large extent, a one size fits all approach regardless of the type of ground you are building on i.e. a concrete and steel foundation that works equally well on all types of earth and varies only slightly in its design. It requires little thought and has been proven to be effective. The cement in concrete provides the compressive strength, and the steel tensile strength to resist cracking. It does however come at a cost to both your pocket and the environment.

When building with earth your foundation needs to be well considered as the integrity of your building rests here. Decisions you make about your foundation depend on the materials you have available, the type of ground you have to build on and what carbon footprint you want to leave. The goal should be to create foundations that are hard enough, move uniformly and resist cracking for the walls above it. Foundations will always have a higher Mpa value than the walls, however it does not need to be excessive. A 4 Mpa foundation is sufficient for a 1.6 Mpa mud-brick wall, which most types of foundations are suitable for. Furthermore, if after levelling the site the undisturbed earth is hard enough, foundations may well be unnecessary.

There are several strategies for foundations depending on the type of ground that you are building on. In this blog post, I discuss the four types of ground, (1) uniformly hard, (2) uniformly soft, (3) hard and soft, and (4) clay, their challenges and several strategies you may incorporate into your design. The discussion is quite technical in some areas so I recommend that you read my three-part series on understanding earth first. Continue reading

TERRA Award ~ first international prize for contemporary earthen architecture

Earth is becoming increasingly popular in contemporary architecture: hundreds of projects of high aesthetic and technical quality are emerging across five continents. This material, which has low embodied energy, is readily available and appropriate for participatory buildings. It could help provide a solution to the needs for ecological and economical housing.

To enable both professionals and the general public to fully appreciate this building material, the following partners have taken the initiative, under the auspices of the UNESCO Chair “Earthen architecture, construction cultures and sustainable development”, to launch the first international prize for contemporary earthen architecture: the Labex AE & CC-CRAterre-ENSAG Lab research unit, the amàco project, the Grands Ateliers, the CRAterre association and EcologiK/EK magazine.

Wang Shu, 2012 Pritzker architecture prize laureate, is the president of honour of this TERRA Award, the trophies for which will be presented in Lyon on July 14, 2016 at the Terra 2016 World Congress.

Context

Since its creation in 1979, the CRAterre-ENSAG Lab has been considered as the international research and training reference centre for earthen construction. It will organize in July 2016, under the auspices of the UNESCO Chair “Earthen architecture”, the Terra 2016. This World Congress takes place every four years on a different continent and will be held for the second time in Europe. It is expected to draw around 800 professionals, teachers and researches to Lyon (France).

The TERRA Award was initiated within this framework. It will be the first international prize for contemporary earthen architecture and a natural furtherance of the national award launched in 2013 in France by CRAterre-ENSAG, AsTerre and EcologiK/EK magazine.

Objective

The purpose of the TERRA Award is not only to identify and distinguish outstanding projects, but also to highlight the audacity of the project owners for choosing to use earth, the creativity of the designers and the skills of the craftsmen and entrepreneurs.
An itinerant exhibition will feature 40 buildings from all continents, constructed using various techniques (adobe, cob, CEB, rammed earth, plaster, etc.) for all types of programs: housing, public facilities, activities, and exterior and interior designs. The exhibition will be completed with lectures and workshops by CRAterre-ENSAG and the amàco project.
The search for outstanding achievements deserving of this prize and the associated exhibition will make it possible to generate the first worldwide database on contemporary earthen architecture. The resulting virtual library will be available both to the general public and professionals via this website.

Involved projects

The projects must have been completed after January 2000.
There are eight categories covering all types of programs, whether new or renovated:

  • Individual housing
  • Collective housing
  • School, sports and health facilities
  • Cultural facilities and religious buildings
  • Offices, shops and factories
  • Interior layout and design
  • Exterior design, art and landscape
  • Architecture and local development

How to incorporate passive solar design in your building, using thermal mass and insulation.

DSC01797_edit 1

Passive solar design is the starting point of sustainable building. Once one understands the basic principles of using the abundant natural renewable resources at our disposal we become more creative in our approach to design, more in tune and observant, reconnecting us with the natural rhythms that surround and sustain us, if only we would pay attention. Sustainable buildings save money, reduce your carbon footprint and provide a healthy living environment, transforming buildings from consumers of energy to producers and forging buildings that meet our needs.

From a permaculture perspective, incorporating these aspects into the design of your home are excellent examples of several permaculture design principles. To mention the most obvious: Observing and interacting with your environment to make the most of the sun’s migration, catching and storing energy, using and valuing renewable resources and services, integrating functions and elements rather than segregating them and obtaining a yield from the planet’s most abundant energy source, the sun.

Passive Solar Design uses the energy provided by the sun and stored in the earth. First we need to look at how this energy is utilized by defining insulation and thermal mass and then look at the strategies of how to incorporate them into our designs.

The dynamic qualities of African Vernacular Architecture

In this guest post written by Jon Sojkowski, he chronicles common misperceptions of African vernacular architecture and how it is being abandoned for the status that comes with living in conventional Western style buildings. He asks whether these modern materials are truly better than the vernacular options.

By Jon Sojkowski

African vernacular architecture is a subject that has had very little attention. The lack of documentation and available data on the internet has led to a severe misunderstanding of a type of architecture that a large percentage of the population in Africa living in on a daily basis. The lack of data has led to negative perceptions regarding African vernacular architecture, mainly that it is temporary, primitive or for the poor. Most people, when they think of a mud hut, get an image of a dilapidated mud structure which is quite small and has a thatch roof. Sadly, this perception exists both inside and outside the African continent, but it is simply not the truth. Continue reading
