+We dedicate this Module to the Mother &

Father of Integral Permaculture: Dana Meadows & Howard Odum, two original

pioneers who helped humanity make great strides in understanding systemic

thinking, in all four quadrants.

This class provides a solid introduction of the science & technology of the home, covering bio-climactic principles as well as choice of materials, location &

design context. But we also question the great emphasis which is put on more & larger

construction by the alternative movement these days.

BioConstruction or EcoBuilding are terms which technically mean 'construction which promotes life' or 'ecological building', not something which is centered - yet again - on consumerist values: putting human whims & comfort above all

else.

How or when are these 'bio' & 'construction' terms used in contradictory ways? Do we need to coin a new 'perma-construction' term?

Class 2.5 of the PDC+++¿How do we ensure optimal resource use &

best choice of materials, interventions & technologies?

This is something so basic that it is quite common to fall into old habits, simply copy what others have done or (even

worse) use the materials 'we like', those we are familiar with, or technologies we find pleasant instead of those

which do, in fact, best fit the criteria of sustainability.

In this class we look at the importance & thinking behind the hierarchy of resources & the scale of interventions, two tools amongst various which we use to ground our designs.

The objective is to create systems that are ecologically sustainable, economically viable, that satisfy needs, don't exploit or contaminate &

that are self-sufficient in the longer-term.

Guidelines for Integral Design1. Make a sketch of your habitual design PROCESS

(e.g.. of the last thing you designed)

2. Observe how it differs from the Design Frameworks (shown in class M2.4)

3. Analyze your Design Motivations (see class M2.3) & if it fits well with your Vision & Mission

4. Are there other designs that could represent a better use of resources (that YOU control) for sustainability?

5. Make a list of the various designs you could make (a brainstorming) & then a PMI analysis of each one.

6. Present this in your Design Portfolio!

... things are a lot more interesting than we usually

imagine ...

in the last 20years, the 500 largest firms in the world

increased their production & sales by 700% whilst

REDUCING their labour force

right now are alive 3/4 of the 65+ year olds that

have ever lived. A fundamental problem of

the 21st century.

we are destroying 200 species per day - all being tranformed to

human biomass

Can we INCREASE in Complexity

Only if we become MORE intelligent :)

Bioclimatic architecture consists in the design of buildings taking into account the climatic conditions, making use of the available resources (sun, vegetation, rain,

winds) to reduce the environmental impacts, trying to reduce energy consumption,

based on principles intertwined with the local culture.

A Big Challenge for All of Us

❖ In Spain we generate more than 550kg of rubbish per person per year

❖ In the Canaries 750kg per person per year (3/4 of a ton)

❖ In each square kilometer of the sea there are floating 18,000 plastic remains ...

❖ ... killing many animals every day

Urgent social need

❖ Soft plastic and plastic fibers’ decomposition time is between20 & 50 years

❖ Hard plastic’s decomposition time is more than500 years

❖ Two huge floating plastic dumps, collected by Pacific currents

❖ Bigger than the USA in area

google Great Pacific Garbage Patch

Urgent environmental need

The Plastic Problem

The Plastic Problem

❖ If it’s burnt in dumps, the problem might be worse:❖ DIOXINS, some of the most toxic known substances,

are generated … & nowadays found even in mother’s milk

Health, environment, social problem…
