The story of the Delft ECD Training Centre

The Training Centre is a passive solar, earth sheltered building out of tyres, cob, compressed earth bricks, ecobricks and glass bottles at the Delft Early Childhood Development (ECD) centre. The design is centered around minimizing the use of cement and concrete whilst showcasing the potential of alternative and sustainable materials. The building feels warm and welcoming amidst a stark social landscape. 
The character of the building is revealed in its hybrid use of natural, recycled and conventional materials and its journey to completion. From the beginning the environment was focused on creating a rich learning environment, starting off with a sustainable building course, progressing under the hands of local community members, interns and volunteers to its full expression as a training centre for early childhood development.

Q&A with Anita Venter, from Start Living Green grassroots development in Bloemfontein

In honour of women’s day we asked Anita Venter a few questions about her grassroots development initiative using sustainable building methods in Bloemfontein. We have great admiration for the shack replacement initiative and what she has done to empower her change agents to become more self-sufficient and build community in her local context. We first got to know of the work Anita does when she invited Peter to participate in the Lebone Arts and cultural centre, a collaborative project with Los Tecnicos in 2014. We were also honoured to host her and six of her change agents on one of our natural building courses in 2015.

How did you first get involved in natural/sustainable building? Tell us about the journey.

Since the early 2000s I have done many research studies on housing from socio-economic and policy perspectives. Continue reading

Join us for a unique free, natural and sustainable learning opportunity

We recently embarked on our first Sustainable Building Course with Earth and Tyres in collaboration with international NGO rockstars Long Way Home. You may have been eager to join in, but due to time or financial constraints had to sit it out? The sustainable building course ends on Friday 19 May, but we still have a lot to do to complete the building. That’s where your opportunity comes in…
Volunteers on site

Natural building course alumni, Bennett and Monre, volunteering on the Delft ECD

Since 2010, I have been dedicated to training people interested in natural and sustainable building. The only common denominator among all the participants was their eagerness to live a life more in harmony with nature and the natural environment.

Since those early days I have seen a steady increase in the number of people interested in what was initially considered an alternative lifestyle. And as the planet seems to be going a little bit more haywire with every passing season, be it electoral or climatic, more and more people are starting a journey towards greater independence and freedom. For many people this means ensuring their primary needs, food, shelter and water are taken care of in one way or another. Often the first step on this journey is building their own dwelling, a deeply satisfying and empowering experience.

Recently, I’ve been engaged with the City of Cape Town and introducing natural and alternative building materials to the public built environment. The first project was the Early Childhood Development (ECD) centre in Delft. Delft, is one of the poorer suburbs in Cape Town with some staggering violent crime statistics. The city is playing the long game as the first 1000 days of a person’s life plays a vital role in the rest of their lives. Early intervention and development is essential. That is why I’m excited about the subtle potential of the environmentally friendly building, exposing children from a young age to the creative potential of earth and other alternative construction materials. And let’s face it, it’s a beautiful and healthy environment that any child will be lucky to grow up in.

But, I wanted to take it a step further and provide a beautiful and natural training space for ECD carers to train in too. We’re presenting it in collaboration with international NGO Long Way Home – tyre building experts and all-round inspiring humans doing amazing things in rural Guatemala. With support from The Sophia Foundation and buy-in from the City we embarked on this journey at the end of April with our very first Sustainable Building Course with Earth and Tyres. You may have been eager to join in, but due to time or financial constraints had to sit it out?

We are busy building a passive solar, earth sheltered building out of tyres, cob, compressed earth bricks, ecobricks and glass bottles at the Delft Early Childhood Development (ECD) centre. But, the sustainable building course ends on Friday 19 May and we still have a lot to do to complete the building (check out our progress). The anticipated date of completion is the end of June. That’s where your opportunity comes in!

We’re sending out a call for volunteers to participate and assist in the completion of the build. It is impossible for us to say what will happen on which dates, but overall the following activities will be taking place from now until the end of June, and we hope you can join us:

  • Cob pack-out and plastering of tyre walls
  • Steel reinforced concrete ring beam installation
  • Bottle bricks in cob
  • Compressed earth brick floor
  • Roof installation
  • Lime plaster finishes
  • Paving
  • Earth berm installation
  • General tom-foolery

To participate in this unique opportunity you need to have completed one of my previous courses. Please email us your name and contact information as well as days that you are available to join us.

To find out more about the Delft ECD centre and what we’ve been up to you can read the article that appeared in Earthworks Magazine, or you can check out the albums on Facebook and Flickr. We’ve also created a series of shortfilms about the different materials that were used in the build, you can check them out here.

We hope you can join us on this journey.

Guest post: Hybrid alternative and natural building blocks at the Delft ECD (Early Childhood Development Centre)

In Delft, an impoverished township on the outskirts of the Cape Flats, local government is changing its approach to building early childhood development centres with a pioneering project showcasing a hybrid of natural building methods and up-cycled waste materials.

Peter McIntosh, founder of the Natural Building Collective was the project coordinator for the alternative materials (natural and recycled) portion of the Delft ECD build.

Delft ECD_Natural building collective

The new Delft ECD (Early Childhood Development Centre) represents the first time that government – in this case the City of Cape Town – has significantly integrated alternative and unconventional building methods for the construction of a public building.

The considered design of the Delft ECD building is an example that will make an essential contribution to the development of South Africa’s youngest residents. The alternative building materials, which include both natural methods (compressed earth bricks and cob) and recycled waste materials (ecobricks, tyres, glass bottles), deviate from conventional brick and concrete, while creating a healthy environment.  Continue reading

Transition Ethics: The Art of Compromise

Do we as ethical natural builders have a right to deny someone a home simply based on the argument of its purity? Surely it’s about having the humility to acknowledge that sustainability is about economy and social justice as much as it is about ecology. Scott Gallant from Rancho Mastatal in Costa Rica writes that the transition ethic says that no one is going from zero to sustainable overnight. Making the transition takes time and, we have to meet people where they are at.

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

TERRA Award ~ first international prize for contemporary earthen architecture

The TERRA award is a collaborative effort on an international scale to enable both professionals and the general public to fully appreciate earth’s increasing popularity as a building material of high aesthetic and technical quality. 

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.

Passive solar design can dramatically reduce our demands on fossil fuels and other forms of energy input, allowing our buildings to become producers and not consumers of energy and resources, supporting us in a healthier more comfortable abundant way.

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.
