The New Green Building Trend is Bricks of Cannabis. Really.

Builders are using cannabis "not in joints but between joists."

The jokes about homes “going up in smoke” are inevitable.

But the truth is that one of the reasons the cannabis-based building material called hempcrete is gaining acceptance in home construction is that it’s entirely fireproof. As a recent New York Times story reported, hempcrete has been used as a building material in Europe for decades, and lately it’s been incorporated in more homes and offices in the U.S. A small group of hemp entrepreneurs envisions a time very soon when hempcrete will be totally mainstream.

Hempcrete is made with the wood-like interior part of a Cannabis plant, which resemble the look and feel of balsa chips. They’re combined with lime and water, and the resulting material is a block that provides terrific natural insulation, while still being flexible, breathable, and, as mentioned already, fireproof.

And there’s no need to worry about teenage hooligans ripping out your insulation to smoke it. Hempcrete contains an almost imperceptible amount of THC, the active ingredient in marijuana that gets you high.

How to Build a cannabrick home

Peacefully Demonstrated outside the Department of Housing May 7 2005
  1. Plant a cannabis seed. Water and allow the plant to grow and produce seed. Plant and water these seeds. Your goal is to grow enough to build a house, you will need about 1 acre to build a 5 roomed home.

    Tyala imbewu ntsangu (ye-cannabis). Nkcenkceshela imbewu uze uyinike ithuba lokuba ikhule ide ikhuphe eyayo imbewu. Uyothi ke uyityale nalembewu uyinkcenkceshele njalo. Injongo yakho kukukhulisa izityalo ezothi zonele ekwakheni indlu, uyakudinga i-acre (malunga nentsimi) enye ukuze wakhe indlu enamagumbi amahlanu.

    Plant 'n hemp saad. Water en laat die plante om te groei en saad te produseer. Plant en water hierdie sade. Jou doel is om  genoeg te groei om 'n huis bou, jy sal ongeveer een aker benodig om 'n 5-kamer huis te bou.

    Sokutshala imbewu insangu njalo. Amanzi nokuvumela isitshalo ukuze zikhule futhi ukhiqize imbewu. Plant namanzi lezi zinhlamvu. Umgomo wakho iwukuba akhule ngokwanele ukwakha indlu, uzodinga 1 Acre ukwakha 5 roomed ekhaya.


  2. Consider the many relevant points presented in the guidelines of Build a house with hemp / Building with hemp.

    Qwalasela yonke imigaqo oyibekelweyo kwincwadana i-Build a house with hemp / Building with hemp.

  3. Start planning where your house will stand. Consider everything about the environment you’ll be building in, like winter and summer sunshine, wind and rain – you don’t want to build on a floodplain, or your house will wash away. Be sure to plan all your water and waste requirements.

    Ceba indawo ozokwakha kuyo indlu yakho. Qwalasela yonke into ngomhlaba lo uzokwakha kuwo indlu yakho, izinto ezinje ngemimoya, ilanga, neemvula zehlobo nobusika, akekho umntu ofuna ukwakha indlu yakhe emgxobhozweni okanye apho iyothi ibe lilifa lezikhukhula khona. Uqiniseke ukuba unamanzi akulungeleyo ukwenza oku.

    Begin met die beplanning, waar jou huis sal staan. Oorweeg dit alles oor die omgewing en jy sal gebou in, soos winter en somer son, wind en reën - jy wil nie op 'n vloedvlakte bou nie, of jou huis sal wegspoel. Maak seker om te beplan al jou water en afval vereistes voldoen.

    Qala uhlela kuphi indlu yakho eyokuma. Cabanga konke mayelana imvelo uyobe ngokwakha ku, efana ebusika kanye kwelanga ehlobo, umoya nemvula-ungafuni ukwakha ethile kwemfunda, noma indlu yakho iyoba basuse. Qiniseka ukuhlela konke amanzi kanye imfucuza izidingo zakho.

  4. Cut the grown cannabis plants down and leave in the field to rett for a week. The morning dew and natural rotting process will loosen the fibers from the plant.

    a. Process the plant matter by cutting leaves and branches off, then hit small bundles the length of the plant over and upturned rake.
    b. The long fiber parts that remain in your hand are good for weaving rugs and making various other items your skills can accomplish.
    c. The seed can be gathered for more housing.
    d. Gather the small woody bits (the hurd) that have fallen, this waste is what will be used in the construction material.

    Sika / sarha izityalo uzibeke egadini ixesha elingangeveki ukuze zibole. Umbethe wasekuseni nezinye izinto zendalo ezibolisayo ziya kuyikhulula I-fibre ezityalweni.

    a. Yikhawulezise ngohlukanisa intonga zezityalo namagqabi, uhlale uyiharika rhoqo.
    b. Intonga ezi zinothi zincede kwezinye izinto ezifana nokwenza ingubo nezinye izinto onothi uzibonele zona ngokolwazi lwakho.
    c. Imbewu inokuqokelelwe ukwakha ezinye izindlu.
    d. Qokelela imithana ethe yaziwela njengokuba uzoyisebenzisa xa usakha indlu yakho.

Be sure to consider all aspects of your house design and structural requirements. Although the cannabis-cement will become stronger than steel in time, it is not advised to build over 2 floors high without considering structural implications. With planning this cement can be used to build up to 4 floors high.

The cannabis-cement will dry over a period of a month (depending on the weather). At this point you will be able to add the roof. Seal your home’s walls with lime; lime external walls annually. Decorate your house with masonry to make it unique, and paint with coloured lime as per custom.

Building industry embraces hemp-based concrete

INDUSTRIAL hemp, widely applauded for its unrivalled green credentials, is emerging with a bright future in the building industry.
Hempcrete
Hempcrete
And one Queensland builder is especially passionate about the material’s potential, is educating visitors from around the globe in how to use it.
Hempcrete Australia director Johan Tijssen, of Maleny, has now built several buildings around Australia using hempcrete, more accurately known as hemp lime composite (HLC).
His latest project is a two-level three-bedroom house nearing completion at Moffat Beach, Caloundra.
Mr Tijssen also conducts regular workshops in hempcrete construction which have attracted overseas participants. The next training is due to run in Perth early in 2015.
“We look at why and how HLC insulation works including aspects such as the hygroscopic nature of hempcrete,” Mr Tijssen said.
“This is its ability to regulate the humidity and temperature in a room.”
Hempcrete was created in the 1980s by a Frenchman restoring old buildings in the Champagne region and it has taken on a new prominence in recent years, particularly in the sustainable housing sector.
Hempcrete
Hempcrete
HLC, a combination of water, hemp aggregate and a lime-based binder, sequesters carbon dioxide for the life of the building and offers excellent thermal insulating and acoustic properties.
Mr Tijssen, who has more than 20 years experience as a builder and has studied hempcrete applications extensively across Europe, is the first in Australia to acquire BCA certification for hempcrete installation and training methods.
He sources industrial hemp grown in the Hunter Valley for his projects but hopes the crop will eventually be grown widely in Queensland. Growers require a permit. The plant is a different strain of cannabis sativa that contains very little of the psychoactive substance found in marijuana.
Mr Tijssen said hempcrete buildings had excellent insulation and thus significantly lower energy costs, and were a good option in cyclone and earthquake prone regions because HLC was more flexible than concrete.
“To an extent the hempcrete wall will flex back, when concrete would crack,” he said.
Hempcrete was also a carbon-negative material, removing more CO2 from the atmosphere than what it puts into it.

Hempcrete Store Wins Sustainability Awards

The Science Museum has been honoured for its green credentials this month by scooping two prestigious awards for its new Hempcrete storage facility at Wroughton.
The innovative storage building which is made from hemp and lime, was honoured for its sustainable design by winning the Sustainability Award at the Museums and Heritage Awards – beating stiff competition from the BP Showcase Pavilion at the Olympic Park and the Museum of Surfing.

The project was also recognised earlier this month at the Greenbuild Awards, where it won the Best Workplace New Build category – fending off competition from organisations such as Co-op and Network Rail.
Like many other national museums, the Science Museum only displays 8% of its collections to the public – there is just not enough space to display any more. The other 92% of the collection is housed in storage facilities. One of these storage sites is a former airfield near Swindon, which holds 16,000 objects including large scale items such as aeroplanes, trains and cars.

The Hempcrete facility was designed as a radical new solution to protecting objects including horse-drawn carriages, fine art works, wooden ship models and paper archives. Many of these objects are sensitive to changing climate conditions such as light, heat and moisture so providing the right environment is essential to prevent deterioration.
The solution was to create a zero-carbon storage building from hemp and lime – low carbon natural materials which provide temperature and humidity buffering and ensure that the museum’s collections are maintained for future generations.

Matt Moore, Head of Sustainable Development, Science Museum said “I’m delighted that the Hempcrete project has won these awards and been recognised by the museums and building sectors. The project is part of a wider remit to reduce emissions across all our sites. Using science and engineering to look after the Science Museum collections seems to be a perfect solution to one of our biggest challenges.”
Hempcrete is a material made from hemp fibre and lime mortar mixed and moulded in precast, pre-dried cassettes to form Hemclad panels. The material is typically used to provide sustainable building materials for housing and industrial building sectors.
As well as protecting objects from deterioration, the Hempcrete facility allows the museum to reduce carbon emissions and make significant energy savings. The new store will be used to house valuable objects from the Science Museum as well as those of its sister museum – the National Railway Museum.

Growing our way out of climate change by building with hemp and wood fibre

Hemp pant
Houses made from hemp could mitigate climate change. Photograph: Roy Morsch/Corbis
From domestic housing to the Science Museum, plant-based construction materials cut reliance on scarce resources and build healthy, efficient and zero carbon buildings

How can buildings help with climate change? It’s all about renewables and “sequestered carbon”.
The Department for Business, Innovation and Skills’ 2010 report on Low Carbon Construction concluded that construction was responsible for around 300m tonnes of carbon dioxide emissions, which is almost 47% of the UK’s total. Of this, around 50m tonnes is embedded in the fabric of buildings.
Making one tonne of steel emits 1.46 tonnes of CO2 and 198kg of CO2 is emitted make one tonne of reinforced concrete. One square metre of timber framed, hemp-lime wall (weighing 120kg), after allowing for the energy cost of transporting and assembling the materials actually stores 35.5kg of CO2.
If we can convert plants into building materials, we are in a win-win situation. Plants use the energy of the sun to convert atmospheric CO2 and water into hydrocarbons – the material from which plants are made.
The plant acts as a carbon store, sequestering (absorbing) atmospheric CO2 for as long as the plant continues to exist. This CO2 is only re-released when the material is composted or burnt, and the great thing is that through replanting it you can re-absorb this CO2 annually, in the case of straw or hemp, or every decade or so in the case of timber, rather than the 300m years that it takes to recycle coal or oil.
Secondly, plant based materials can be used to make high performing building envelopes, protecting against external weather and making a building more comfortable, healthy and energy efficient to live in.
Not only can they be used as insulation materials, displacing oil-based alternatives such as polyurethane foam, but they also interact with the internal environment in a way that inorganic materials just can’t do.
This is because they are “vapour active”. Insulating materials such as hemp-lime, hemp fibre and wood fibre are capable of absorbing and releasing water vapour. This is doubly effective, because not only can they act as a buffer to humidity (taking moisture out of the air), but they also stabilise a building’s internal temperature much better through latent heat effects (energy consumed and released during evaporation and condensation within the pores of the material).
To build using hemp, the woody core or shiv of the industrial hemp plant is mixed with a specially developed lime-based binder. Factory-constructed panels are pre-dried and when assembled in a timber frame building, the hemp shiv traps air in the walls, providing a strong barrier to heat loss. The hemp itself is porous, meaning the walls are well insulated while the lime-based binder sticks together and protects the hemp, making the building material resistant to fire and decay. The industrial hemp plant takes in carbon dioxide as it grows and the lime render absorbs even more of the climate change gas. Hemp-lime buildings have an extremely low carbon footprint.
Building with hemp lime

In this way bio-based materials can be used to construct “zero carbon” buildings, where the materials have absorbed more CO2 than is consumed during construction. By applying PassivHaus principles (the voluntary industry standard for low-carbon design) to bio-based buildings, a building’s energy use once inhabited can also be reduced to minimal levels. This is a true “fabric first” approach, where the fabric of buildings passively manages energy consumption, rather than purely relying on renewables such as solar panels and ground source heating systems, which have a more limited life-span and the potential for failure.
I worked on a project recently for the Science Museum to reduce the high energy cost of archival storage. They needed to have large enclosures kept at a steady humidity and temperature to ensure that items ranging from the first edition of Newton’s Principia through to horse drawn carriages and even Daleks do not deteriorate. Normally this uses energy intensive air conditioning systems.
The three-storey archival store that the Science Museum built in 2012 using a hemp-lime envelope was so effective that they switched off all heating, cooling, and humidity control for over a year, maintaining steadier conditions than in their traditionally equipped stores, reducing emissions while saving a huge amount of energy.
Improved bio-based materials can also passively improve the internal air quality of buildings by interacting with airborne pollutants, removing them from the building. The new HIVE building – a £1m project funded by the Engineering and Physical Sciences Research Council – has been designed as a platform for research projects into this kind of sustainable construction. The HIVE has a purpose-built flood cell, which will also support research into creating buildings and building materials that are more flood-resilient – a valuable resource in these times of climate change induced adverse weather conditions.

Industry and government must also embrace the opportunities presented by bio-based construction materials to reduce emissions. Domestic housing is a key part of this. Good quality housing can be built out of structural timber with a bio-based insulating envelope using straw; hemp-lime, or other systems using wood fibre or other cellulose fibres.
With domestic housing high on the government’s agenda, it is time the construction industry recognised the economic and environmental benefits of bio-based construction materials and became less reliant on depleting resources including oil and steel.

  1. Plant a cannabis seed. Water and allow the plant to grow and produce seed. Plant and water these seeds. Your goal is to grow enough to build a house, you will need about 1 acre to build a 5 roomed home.

    Tyala imbewu ntsangu (ye-cannabis). Nkcenkceshela imbewu uze uyinike ithuba lokuba ikhule ide ikhuphe eyayo imbewu. Uyothi ke uyityale nalembewu uyinkcenkceshele njalo. Injongo yakho kukukhulisa izityalo ezothi zonele ekwakheni indlu, uyakudinga i-acre (malunga nentsimi) enye ukuze wakhe indlu enamagumbi amahlanu.

    Plant 'n hemp saad. Water en laat die plante om te groei en saad te produseer. Plant en water hierdie sade. Jou doel is om  genoeg te groei om 'n huis bou, jy sal ongeveer een aker benodig om 'n 5-kamer huis te bou.

    Sokutshala imbewu insangu njalo. Amanzi nokuvumela isitshalo ukuze zikhule futhi ukhiqize imbewu. Plant namanzi lezi zinhlamvu. Umgomo wakho iwukuba akhule ngokwanele ukwakha indlu, uzodinga 1 Acre ukwakha 5 roomed ekhaya.


  2. Consider the many relevant points presented in the guidelines of Build a house with hemp / Building with hemp.

    Qwalasela yonke imigaqo oyibekelweyo kwincwadana i-Build a house with hemp / Building with hemp.

    Oorweeg die baie relevante punte in die riglyne van die Build a house with hemp / Building with hemp.

  3. Start planning where your house will stand. Consider everything about the environment you’ll be building in, like winter and summer sunshine, wind and rain – you don’t want to build on a floodplain, or your house will wash away. Be sure to plan all your water and waste requirements.

    Ceba indawo ozokwakha kuyo indlu yakho. Qwalasela yonke into ngomhlaba lo uzokwakha kuwo indlu yakho, izinto ezinje ngemimoya, ilanga, neemvula zehlobo nobusika, akekho umntu ofuna ukwakha indlu yakhe emgxobhozweni okanye apho iyothi ibe lilifa lezikhukhula khona. Uqiniseke ukuba unamanzi akulungeleyo ukwenza oku.

    Begin met die beplanning, waar jou huis sal staan. Oorweeg dit alles oor die omgewing en jy sal gebou in, soos winter en somer son, wind en reën - jy wil nie op 'n vloedvlakte bou nie, of jou huis sal wegspoel. Maak seker om te beplan al jou water en afval vereistes voldoen.

    Qala uhlela kuphi indlu yakho eyokuma. Cabanga konke mayelana imvelo uyobe ngokwakha ku, efana ebusika kanye kwelanga ehlobo, umoya nemvula-ungafuni ukwakha ethile kwemfunda, noma indlu yakho iyoba basuse. Qiniseka ukuhlela konke amanzi kanye imfucuza izidingo zakho.

  4. Cut the grown cannabis plants down and leave in the field to rett for a week. The morning dew and natural rotting process will loosen the fibers from the plant.

    a. Process the plant matter by cutting leaves and branches off, then hit small bundles the length of the plant over and upturned rake.
    b. The long fiber parts that remain in your hand are good for weaving rugs and making various other items your skills can accomplish.
    c. The seed can be gathered for more housing.
    d. Gather the small woody bits (the hurd) that have fallen, this waste is what will be used in the construction material.

    Sika / sarha izityalo uzibeke egadini ixesha elingangeveki ukuze zibole. Umbethe wasekuseni nezinye izinto zendalo ezibolisayo ziya kuyikhulula I-fibre ezityalweni.

    a. Yikhawulezise ngohlukanisa intonga zezityalo namagqabi, uhlale uyiharika rhoqo.
    b. Intonga ezi zinothi zincede kwezinye izinto ezifana nokwenza ingubo nezinye izinto onothi uzibonele zona ngokolwazi lwakho.
    c. Imbewu inokuqokelelwe ukwakha ezinye izindlu.
    d. Qokelela imithana ethe yaziwela njengokuba uzoyisebenzisa xa usakha indlu yakho.

    Sny die gegroei hemp/cannabis plante af en in die veld verlaat om rhett vir 'n week. Die oggend-dou en die natuurlike verrotting proses sal die vesel van die plant los te maak.

    a. Proses van die plantmateriaal deur te sny blare en takke af, dan is getref klein bundels die lengte van die plant oor en omgekeerde hark.
    b. Die lang vesel dele wat in jou hand bly is goed vir die matte weef en die maak van verskeie ander items jou vaardighede kan bereik.
    c. Die saad kan vir meer behuising ingesamel word.
    d. Versamel die klein houtagtige bits (die hurd) wat gedaal het, die afval is wat sal in die konstruksie materiaal gebruik kan word.

    Sika izitshalo insangu njalo. isikhule phansi endle ukuze rhett isonto lonke. Amazolo ekuseni inqubo lwemvelo ukubola kuzokwenza athambise imicu kulesi simila.

    a. Ukucubungula udaba plant ukusika amaqabunga namagatsha ahambe ke hit izinyanda amancane ubude sitshalo phezu ne hala sokutakula.
    b. I-long fibre izingxenye ezisele esandleni sakho kukhona okuhle ngokuba ihlanganisa omata kanye nokwenza ezinye izinto ahlukahlukene amakhono akho kungaba afeze.

Dibanisa ngokwalo mgaqo 10:2:3:3, dibanisa ke lemvuno yakho yomgquba wentsangu (10) kunye nesanti yasemlanjeni 0.5mm(2), ikalika (3) kunye namanzi (3) ukwenza udaka (Nale into ke iyokuthi ixhomekeke kwindawo leyo ukuyo nemvula zakhona njalo-njalo).

    Was die kudde, droog dit af, dan was dit weer. Wees versigtig om nie toe te laat die aangeleentheid te verrot of verval gedurende hierdie proses, deur die draai, voorlê en laat die Afrika-son om droog die kudde goed. Nou kombineer in verhoudings 10:2:3:3 kombineer die cannabis / ntsangu / dagga Hurd (10), gewaste riviersand 0.5 mm (2), hidrouliese kalk (3) en water (3) aan die deklaag te maak (Hierdie proses kan tweaking nodig, afhangende van jou geografiese ligging, humiditeit, reën, ens)

    Geza the hurd , zoma it ke geza futhi . Qaphela ukuba singavumeli udaba ukubola noma ukubola kulo msebenzi , ngokubhekisa , angabiki futhi sivumele ilanga Afrika ukuze ome le hurd kahle . Sebesebenzisa ngezabelo 10:2:3:3 hlanganisa insangu njalo. / ntsangu / insangu Hurd (10) , umfula wageza isihlabathi 0.5mm (2) , wokubacindezela umcako (3) kanye namanzi (3) ukwenza semboza ngabo izithombo zezihlahla (Le nqubo may badinga tweaking kuye ngokuthi indawo yokuhlala yakho, umswakama, imvula, njll)

  6. Now build your house! Ngoku ke yakha indlu yakho! Nou bou jou huis! Manje ukwakha indlu yakho!

  7. Teach others. Fundisa abanye. Onderrig ander.

You can use this “dagga-cement” for making bricks, shutter casting or the proven “pole-and-dagga” method. This last method allows for a sturdy, warm, fireproof and water proof home – built with pride and intuitive engineering, not a ‘uniform box’.

Be sure to consider all aspects of your house design and structural requirements. Although the cannabis-cement will become stronger than steel in time, it is not advised to build over 2 floors high without considering structural implications. With planning this cement can be used to build up to 4 floors high.

The cannabis-cement will dry over a period of a month (depending on the weather). At this point you will be able to add the roof. Seal your home’s walls with lime; lime external walls annually. Decorate your house with masonry to make it unique, and paint with coloured lime as per custom.

Always PLANT A TREE in a place that will provide shade, to commemorate this accomplishment.

Assist your family, friends or neighbors with your experience and expertise. Share information and technique; you can uplift yourself and your community.

Zuma notes MP’s call for medicinal canabis

Cape Town - IFP MP Mario Oriani-Ambrosini’s urgent call for the legalisation of marijuana for medicinal use seems to have found an ear in the country’s top office.

“I was touched to see the man I’ve known and worked with for more than 20 years in this condition. I’ve asked the minister of health to look into this matter,” President Jacob Zuma said on Thursday during his reply to the parliamentary debate on the State of the Nation address.

Less than two hours earlier, Oriani-Ambrosini, flanked by IFP president Mangosuthu Buthelezi and IFP caucus chairman Ndlovu Velaphi, released details of his private member’s bill, the Medical Innovation Bill.

“I am here because I am a man of principle. This is not an easy thing to do,” said Oriani-Ambrosini, the day after he used his four minutes in the parliamentary debate on Wednesday to make his call – almost a year after he was diagnosed with terminal lung cancer.

“I am now in the 0.01 percent survival rate… Being a politician, paid by the people of South Africa to do a job, it became natural for me (to speak) for those who do not have a voice. The most important thing to do is to remove the legal obstacles.”

His private member’s bill seeks to make it possible to prescribe marijuana, or other alternative treatments, to terminally ill patients. It excludes doctors and patients from possible prosecution, seeks to regulate the use of medical marijuana – “to trade criminal profits into tax for people”, according to Oriani-Ambrosini – while also establishing at least one research hospital for medical treatment innovation.

Published in the Government Gazette on Valentine’s Day, the private member’s bill also sets out a framework for the commercial and industrial uses of cannabis, which is already used in textiles and building materials in a global industry.

“This is my contribution – I don’t want to say last contribution – I hope God will give me the strength… ” said Oriani-Ambrosini, who with his usual self-depreciating wit touched on the consequences of using medicinal dagga.

“There are no side effects except my hair growing curly for the first time in my life. I’m still looking to manage this,” he quipped, adding that he appreciated his glowing skin.

Buthelezi confirmed his support for his MP.

“Dr Ambrosini, we have travelled a long road with him. We have slaughtered many monsters… He has taken on one of the most fearsome monsters at this time.

“I do hope, with God’s help, he will do something not only for himself, because this is not his attitude, but for the whole human race.”

Advocate Robin Stransham-Ford, also a cancer patient on alternative treatment, outlined plans to push for a constitutional challenge to decriminalise dagga for medicinal use next year, but acknowledged Oriani-Ambrosini’s request to try for a political solution.

It is understood the president has already received from Oriani-Ambrosini the large volumes of work of the South African national working group on the medicinal use of marijuana.

Submitted to the government last November, it includes reports on various clinical trials, including several run by US teaching hospitals, on the benefits of medicinal marijuana.

#WDC2014 is the first word in innovation

Cape Town - Remember this hashtag #WDC2014. Use it, retweet and spread the word that Cape Town, as the World Design Capital 2014, is showcasing innovative designs that will uplift communities throughout the city.

Speaking at the official launch of the World Design Capital 2014 (WDC2014) programme on Thursday, mayor Patricia de Lille said almost 700 submissions had been received from design students, non-governmental organisations and residents during the 10-month proposal period.

The 450 projects that were selected represented a “selection of innovative creations that will uplift communities to have a stake in the future of the modern global city that Cape Town aspires to be”, she said.

Each project has its own hashtag and geolabel, so it can be followed and found long after 2014. Open Streets, an initiative encouraging car-free streets, can be found on #WDC207, for example.

Alayne Reesberg the chief executive of Cape Town Design, said: “We can’t emphasise enough how extraordinary the submissions were.”

They followed four themes: African innovation, global conversation; bridging the divide; today for tomorrow; and beautiful spaces, beautiful things.

One of these projects, Kaya Labs, overcame the digital divide by creating computer labs from containers so that township residents have access to the internet.

Richard Perez, the programme director for the WDC, said each of the city’s 111 wards would have co-design workshops where councillors and officials, community organisations and designers could work together to find creative solutions to their problems.

Many of these would deal with upgrading parks and public spaces. “The idea is to deliver some of the projects in 2014.”

It was also about getting the city council to incorporate design thinking into its organisational structure. This meant that future plans and policies should include aspects of design that would create a more sustainable and inclusive city.

The year-long programme includes five WDC signature events, the city’s ward projects and existing events that will be leveraged for WDC 2014. The programme starts with a bang on the December 31 as the city hosts its biggest New Year’s bash.

Other events include the vegetable garden at the Company’s Garden, an outdoor solar sculpture that will be self-illuminating at night, a multilingual translation application for use on mobile phones and a community-led project to redesign the layout of informal settlements.

Although the official WDC projects have been identified, everyone is encouraged to get involved. All events and exhibitions would be free and open to the public, said WDC2014 media manager Priscilla Urquhart.

Also in the pipeline are design “bootcamps”, at which high school pupils will be encouraged to hone their creative skills, and maybe take up a design-related career.

“There has been huge interest from international media and publications such as Wallpaper, because of our unique approach to resolving pernicious issues,” said Reesberg.

“We’re addressing universal issues for emerging markets.”

The World Design Capital is an initiative of an international NGO, the International Council of Societies of Industrial Design, to promote industrial design.

Cities that in the past have been designated World Design Capital include Torino in Italy, Seoul in South Korea and Helsinki in Finland. Cape Town is the first city in Africa to hold the title.

Housing backlog will cost R800bn

 South Africa needs at least R800 billion - and a “miracle” - to clear its housing backlog of 2.1 million houses within the next seven years.

This is according to the Finance and Fiscal Commission (FFC) which released its report on “alternative finance and policy options for effective and sustainable delivery of housing in SA” on Monday.

It also believes the present approach to housing provision won’t be sustainable.

The FFC’s main responsibility is to make recommendations on the “equitable” division of revenue between the three spheres of government and provide advice to organs of state on financial matters.

The head of the commission, Bongani Khumalo, said the housing sector faced many challenges. This included increasing housing backlogs and a decreasing number of low-cost houses being provided by the government.

Some of the reported 3 000 service protests in the country since 2009 have been blamed on unfulfilled promises of RDP houses. Khumalo said the backlogs had increased from 1.5 million housing units in 1996 to 1.8 million units in 2001 and then 2.1 million in February this year.

“If we were to look at the demands or backlogs that we currently have, and we have to eliminate those by 2020, the total amount required for that period is about R800bn to actually eliminate in the next seven or eight years,” said Khumalo.

He said this would translate to more than R120bn a year.

The government allocates about R30bn to provide housing. “So the sustainability is really an issue, unless a miracle happens… And also it’s important that when look at sustainability, we also look at the track record,” said Khumalo.

He said the housing sector was also affected by the “unique phenomenon” of an increasing gap market.

The gap market is made up of households earning too much to qualify for subsidised housing, just above R3 500 a month, and too low to qualify for mortgage bonds, earning about R15 000.

Khumalo said overall, the commission concluded that different households in different housing circumstances required specific interventions and a different approach. He said one solution would be to encourage additional funding from the private sector as well as household contributions towards housing provision.

However, he stressed that “the choice remains the government’s”.

The FFC’s warning comes a month after researchers reportedly said that the housing waiting list, used by the government to allocate RDP houses on a first-come-first-served basis, was a “myth”.

A report by the Socio-Economic Rights Institute and the Community Law Centre at the University of the Western Cape apparently found that there were multiple mechanisms and systems to allocate housing, some of which were out of sync with one another.

The report scrutinised the provision of housing in Gauteng and the Western Cape.

It said that beneficiaries were often forced to rely on luck to get houses. “Other… idiosyncratic and often community-based methods are adapted to local situations.”

Hemp expected to take off as building material as first hemp house opens in Thornbury

VICTORIA'S first house built from hemp will open to the public next month.

Architects Dorit Przyeorowski and Steffen Welsch, who designed the Thornbury house, said the much-maligned hemp plant was set to take off as a sustainable building material with its excellent insulation properties.

"Everyone smiles and laughs when they hear about hemp as a building material because they associate it with marijuana, but it's a slightly different crop and you can't smoke it," Mr Welsh said.

"We believe it has a big future as a material for housing on a small and medium scale."

Ms Przyeorowski said hemp had strong environmental credentials because it was fast growing and stored carbon dioxide.

She said it had low embodied energy and the potential to make walls carbon neutral.

>>Would you consider using hemp as a building material? Tell us below.

The hemp is mixed with lime and water and then poured into formwork, similar to the way in which rammed earth walls are made.

Owner Michelle McGeachen said she and her husband, two children and parents were looking forward to opening their Northcote home to the public and inspiring other people to consider using the new building material.

"It's a little bit more expensive, but you offset the expense with the reduced heating and cooling costs," she said.

"The house is lovely and warm in winter and will be cool in summer."

Ms McGeachen said the material was also strong, durable and weather proof.

The not-for-profit Alternative Technology Association has organised the Sustainable House Day opening.

The hemp house is open on Sunday, September 8, from 10am to 4pm, at 123 Jenkins St, Northcote.

GOING GREEN

Sustainable living is becoming a “hot topic” and adapting to this lifestyle can create a bigger and brighter future for all generations.  People are now considering ways to reduce their ecological footprint by driving less in their own transport, reducing their meat intake and even wearing sustainable and affordable fashions.  As individuals, we are increasingly aware of the impact we have on the natural, social and economic environment, thus adapting to sustainability can only benefit each individual in the long term

Science the key to SA's future: Motlanthe

Problems inherited from the apartheid era can be solved through research, Deputy President Kgalema Motlanthe said on Saturday.

"Inevitably, most if not all the historically inherited challenges constituting a dead weight on our development ambitions can only be addressed through the research agenda of our national research institutes," he told a summit on science and technology in Polokwane, Limpopo.

Motlanthe said national research institutes had the task to remain relevant to the developmental agenda through the use of science, technology and innovation.

"In other words harnessing the force of science and technology to meet our developmental needs is among the surest ways out of the current quagmire of under-development," he said.

Motlanthe said through the National Development Plan, government laid out the parameters within which each social partner could make a contribution towards the achievement of the country's shared vision.

"This shared vision entails the reduction of poverty, stimulating economic growth, effecting economic transformation and creating employment."

He said South Africa needed to do more in mobilising resources for the task of producing quality education for both teachers and learners alike.

"Only a sound and quality education system with strong emphasis on mathematics and science can serve as a reliable feeder for tertiary institutions...," he said.

Motlanthe said research projects were carried out disparately without knowledge sharing and co-ordination to avoid duplication.

"Our national research efforts lack a central framework or institute to define and identify the most immediate projects, resulting in duplication, wastage and inefficient use of funding."

The lack of collaboration robbed the country of the benefits which would accrue from research.

Research institutes could commission a study of the systemic failure in the governance system and how best could government address its problems, he said.

Motlanthe said under-utilisation of existing research institutes by government often led to wasteful expenditure in that each government department commissioned research in common areas.

"I submit that the benefits of science, technology and innovation are not only potentially immense for us but also, and more crucially, constitute the pre-conditions for South Africa's development."
