We’re thrilled to announce Peter McIntosh will be co-facilitating Long Way Home’s inaugural Green Building Academy in Guatemala this year. Participants can expect a solid grounding and hands-on experience in green, sustainable building and construction practices, social development and a rich cultural immersion. The Academy will take place in Comalapa, Guatemala, and will draw on the expertise of the Academy‘s instructors, who for 9 years have built an 18-building school using state-of-the-art green and sustainable technologies and methods.
The Green Building Academy provides a menu of unique educational options that are relevant to both professionals and students inside AND outside of the construction industry. Guided by best practices in green construction, the Academy is dedicated to educating individuals and organizations, in both theory and practical application, about sustainable design, planning, and building practices. Participants will connect to their environment, and develop increased consciousness & competence relating to sustainability, environmental & ecological balance, and ethical & respectful community development. The Academy equips participants with the knowledge, skills, and dispositions to apply their creativity to design and construction using sustainable, unconventional materials and low-impact methodologies with potential for off-grid implementation.
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.
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.

Thank you, I am very pleased for recognition of this off grid, rammed earth building , where I designed and built the house, energy & water systems and sewerage.

How did you first get involved in natural building?
I have been always interested in natural buildings and as a student studied natural building in Malawi and Zambia. I have travelled a lot in remote Africa and have an interest in indigenous architecture which is both material and energy efficient. Continue reading →
In the first of our series of Q&As with pioneers of natural and sustainable building in South Africa and beyond, we caught up with Jill Hogan in honour of Women’s day in South Africa.
How did you first get involved in natural building?

In the early 90’s my life changed completely and I found my self alone. In wanting to be part of a community, I met Hurta Stuurman and did some work with her on her cob house at Hermanus/Stanford and knew that this is what I wanted to do. It combined my concept of Permaculture with creating an organic home for myself, while allowing me to use my knowledge of earth/clay.
Tell us about your journey.
In the 70’s I worked for a nursery. I had a pot plant business, but was exposed to organic veggie gardening and became more and more interested. At the same time, I started doing pottery and assisted in teach children with learning disabilities now known as ADHD, and so was exposed to lateral thinking.
In the 80’s I went back to “school” and did a fine arts majoring in ceramics.
In 1992 I was introduced to Permaculture and did the design course with John Wilson from Fambidanzia, at Tlholego in Rustenberg, and I developed a true passion for sustainable development.
Someone was setting up an Eco Village in McGregor and I was drawn to become one of the original developers. But personality clashes among the original six members caused the project to collapse, sending me into McGregor itself where I bought a piece of land in the town. Continue reading →
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.
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.
As the cost of power continues to rise and the cost of solar energy continues to drop, going off grid has never been easier. Learn how to calculate your energy requirements, as well as choose an inverter, batteries and solar panels to suit your needs.
As we’re heading into winter South Africa’s continued loadshedding will have an even greater affect at home and work as people spend more time indoors requiring amongst other things more lighting as well as heating. We are blessed with abundant sunny days making solar very reliable without the need for a lot of backup storage in the form of batteries. If you are considering going off the grid, whether partially or fully, my previous post will give you a basic understanding of how solar energy works and the components of the system. In this post, I show you how to calculate your energy requirements, as well as choose an inverter, batteries and solar panels to suit your needs.
Being dependent on a central power source is not very powerful at all, especially as costs of centralized large-generation capacity gets ever more expensive, while the costs of solar energy continues to fall.
Recently, in South Africa the centralized electrical grid is unstable and has led to the current reality of regular power outages; subsequently many people are considering solar as an alternative. We are blessed with abundant sunny days making solar very reliable without the need for a lot of backup storage in the form of batteries. These equations shift depending on where you live, however even countries like Germany which is not as blessed with as much sunshine, place a large emphasis on solar technology as part of their energy solution. Whether you live connected to the electrical services grid, or off-the-grid, there are compelling reasons to use alternative sources of energy.
This post will give you a basic understanding of how solar energy works and the components of the system. If you have no experience in electrical energy at all it may seem a little daunting, however the math is really simple and with a little practice it’s as easy as ABC.
