Richard Horden “Beach Point” 1997

Design a subconsent Surf Lifesaving Tower.

Two or more A3 sheets due 30 Aug 2013 12:00 noon.

Background

How are we going to live well, with purpose, with more community, and with less reliance on resources like materials and energy?

The SHAC Challenge is a way to learn about the building code, experiment with buildings, and to develop prototypes for our new built environment. We designers, engineers, architects, builders, and others will be creating our new built environment for the rest of our lives.

This challenge has entrants considering a a key future design need: structures that sit off of the ground, on potentially adjustable supports.  How is the structure anchored to the ground?  Are the anchors durable? When will the structure overturn?

Objectives
* Provide a playful competition to help designers, builders and the public better understand the art and science of building.
* Promote design and build as a collaborative, evolutionary process
* Promote the re-use of building materials
* Promote living well, with purpose, and with less reliance on money and resources
* Promote creative responses that do not require a large budget

Design Requirements
* The building must not require building consent, as per the DBH discussion document.  Example exemptions (daawalls fences), (gadecks), (i10m2 buildings), (jveranda/patio/porch/awnings), (jb - pergola), (je - shade sail), (jf - carport), and (k – low cost / consequence).  Exemptions can be combined.
* The building will provide for use as a surf life saving tower. It may also provide other use(s) now or in the future.
* The building may make use of recycled building materials.
* The building may make use of solar energy: eg, passive solar, solar electric, or solar thermal technology.

Entry Requirements
* Due Date – 30 Aug 2013
* Please supply two A3 presentation sheets that explain the project. This may include 3D sketches, plans, elevations, sections, and/or photos of the materials or techniques to be used.
* Entries not to include names or logos, only your assigned number. Register for your number here
* List the exemptions used from Schedule 1 of the building Act.
* In up to 50 words, explain the project and its purpose, it’s present and potential future uses.
* In up to 100 words, explain how it could be constructed
* How will it be supplied with any electrical power, and water, if needed.
* You may choose to include a sketchup file. Photos of projects underway are acceptable.
* Please submit the A3 sheets as PDFs.
* Please submit all files electronically to tim@shac.org.nz.
* Maximum size about 15 MB per email.
* Submitted designs should be copyrighted by the author(s) under a Creative Commons license of your choice, suggested: “CC-Attribution” or “CC-Attribution-NonCommercial”* Questions can be sent to tim@shac.org.nz, and answers will be sent to all registered teams.

* SHAC reserves the right to not accept any entries.
* Best entries will be honoured with awards and prizes at the Christchurch Festival for Transitional Architecture – 24-28th October 2013.  FESTA.org.nz
* All entries may be published by SHAC on our web site or other medium.
* Thank you for your submission!

Intensive Urban Agriculture

I seem to get confused often by the word garden. I always think vegetables, but sometimes I later realise that people mean decorative gardens! When I was in Japan last month I specifically went to Kyoto because I heard it was called a garden city.

The Japanese were very hungry at the end of the second world war. Vast areas of the urban landscape had been destroyed. In the first 7 postwar years, three large earthquakes also contributed to the difficulties.

Intensive gardening and farming fills the suburban neighbourhoods of Kyoto. Groups of two and three story houses with private decorative gardens are surrounded by paddocks of vegetables and rice.

For a peppercorn rent, residents let a few furrows for their own use, or larger areas to sell to local shops.

The lack of fencing allows for small tractors and other machinery to be used and shared by many.

Kyoto is known for the garden city – for its decorative gardens – but I like the productive vegetable gardens.

Japan is fascinating. The Japanese are so respectful of everything -work, other people, the natural world. And they have so many rituals – for me it seems to be a way to relax. Together it makes for a human society that is synchronized with the natural environment. Their technology is very efficient and they husband their natural environment so as it produces so many useful things from urban land, rural land, and even the forests. Japan is about 130% the size of New Zealand. And they are worried that they only produce food for about 40% of their population. That is 48 million people!

Kyoto

In early February I visited Tokyo and Kyoto. Tokyo is the megalopolis – it has huge apartment buildings that extend as far as I could see from the 18th floor of my hostel. Kyoto on the other hand is largely 2 and 3 story buildings interspersed with many decorative gardens, temples, and productive fields.

I presented at the “Earth Systems Governance Conference Tokyo 2013” at the United Nations University. Yes I fell off my chair when I was accepted to speak at this conference!!

The conference is trying to raise the point that all of humanity is a system “governed” by written and unwritten, or formal and informal, rules and norms.

The conference did attract many presenters on top-down international relations and nuclear energy policy, however the project is also about “bottom up”, grassroots changes in our human-made earth system.

It was a fascinating conference – I was astonished that the people that consider big global issues find what we are doing in Christchurch interesting.

Presently, in New Zealand, the current set of unwritten rules and norms say: “houses are very expensive; spending 5 times your annual income on your house is the best way to save for the future; building a house is best left to the experts; group action is ineffective; excellence and high performance is the sole realm of the highly trained professional; making positive change in your life is profoundly difficult and best left to the experts.”

I presented on the emerging network of groups in Christchurch that are showing other possibilities and suggesting new norms.  These groups are creating new possibilities and presenting new ideas that will likely lead to a more sustainable built environment.

One key idea is that we use volunteers and skilled people collaborating together. Another is that you don’t need to be a highly trained person to start something.

There is an informal network of groups in Christchurch that have responded to the earthquake are rewriting the informal rules, and creating new norms. These groups include Greening the Rubble – [gardens can be anywhere!], Gapfiller – [life is a stage!], CPIT – [we are learning by doing!], Live in Vacant Spaces [there are other ways to access land!], The Concert [volunteers are effective, and it is very fun!], Rekindle [we don’t have to throw those building materials away!], White Elephant [young people create and do!], Renew Brighton [a community can remake itself] Maybe one day the formal rules could change, in response.

Written rules also have an impact that was recently documented by Stu Donovan on transportblog.co.nz

The primary impact of local government regulations is not through the constraints they place on land supply (i.e. urban containment), but actually through the barriers they create to the development of more compact and affordable housing. Here’s some examples of regulations pursued by local governments in New Zealand that seem likely to restrict the supply of affordable housing:

  1. Minimum lot sizes – i.e. “all ye who have less money shall be forced to purchase land you don’t want.
  2. Minimum apartment sizes – i.e. “all ye who have less money shall be forced to purchase living space you don’t want.
  3. Minimum parking requirements – i.e. “all ye who have less money shall be forced to pay for vehicles you don’t own”.
  4. Maximum height limits – i.e. “all ye who chose to live like rats are consigned to perish like rats – on the street.
  5. Heritage protections – i.e. “all ye who don’t have the money to renovate a villa shall live elsewhere.

The Earth Systems Science Plan defines the five analytical problems of governance. The five A’s, for short: Agency – to what degree groups and individuals feel like they can act to create positive change. Allocation and Access – how individuals and groups are allocated or access needed resources like land, housing, food. Accountability – projects are legitimated – how do we know about, participate in the decision making around projects that affect or interest us? Adaptiveness – how do we change or reorganize in response to needs? And finally, Architecture – what structure of organization allows for good outcomes in the other areas? For example, what type of command and control, what processes or procedures, or what norms?

In Christchurch we have a loose network of groups that come together for various projects as suits each group. Each group thus retains its own agency – the ability to act. There are no formal contracts between groups that restrict or prohibit action.  Each group has a few energetic coordinators who harness the capacity of skilled professionals and keen volunteers/apprentices. No explicit coordination between groups is needed. Each group’s actions are coordinated by skilled and resourceful coordinators who keep the momentum going.

Projects are “legitimated” when people volunteer to do them. Good projects are supported by volunteers. Employees do what their bosses say, but volunteers only work on things they believe in.  More volunteers equals more legitimacy equals more impact. It is unlikely that an unpopular project will have a big impact, while popular projects will grow and grow.

And It seems that from this architecture of a loose affiliation of interacting groups, supported by a mix of volunteers and professionals, emerges a system that can support a more sustainable built environment.  In other words it supports supports multiple groups to have agency, to have legitimacy, and to demonstrate other ways of allocation and access to resources.

Will this hodge-podge of groups lead to a more sustainable built environment? This is still to be discovered. I had an intuition that this was the case, and the conference introduced me to the academic literature further supports this case:  That small, self-governing systems of local groups do effectively and fairly allocate limited resources. See, for example, the work of natural resource economist Elinor Ostrom.

We are prototyping possibilities for the future today!

+1
  

A Sustainable Office Chair? $200 cash prize!

David McKay makes a convincing argument that 40% of our total energy use goes to make the products that we buy.

Announcing a SHAC Micro-Challenge – The “Sustainable Office Chair”

Please submit your sketch or photo of your practical and comfortable Sustainable Office Chair.

Is it one made from natural materials, or a durable and repairable chair that lasts for many years, or one made from entirely recycled products, or hand made, or made by a machine like a 3D printer, or a chair that is made from starch and dissolves when wet?

Judging: Chair must be practical, comfortable, suitable for your office, and “sustainable”

Please supply a photo or sketch and a short description, how to make the chair, and how is the chair “sustainable” – that is – supporting living well, with purpose, and with less reliance on resources.

Please email your submissions to tim@shac.org.nz by the 24 October 2012.  $200 cash prize for the best submission.  Other prizes too! The judges decision is final.  The best submissions will be exhibited publically.
