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?

PDC+++ Module 4 Class 7 PermaConstruction

  1. 1. + PDC Module 4 of the PDC++++ + Energy & EcoTechnology We dedicate this Module to the Mother &Class Father of Integral Permaculture: Dana Meadows & Howard Odum, two originalM4.7 pioneers who helped humanity makePerma great strides in understanding systemic thinking, in all four quadrants.Constru-Action 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?

  5. 5. 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 wefind 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.
  6. 6. Guidelines for Integral Design1. Make a sketch of your habitual design PROCESS (e.g.. of the last thing you designed) Individual2. Observe how it differs from the Design Frameworks (shown in class M2.4) 1 6 43. Analyze your Design Motivations (see class M2.3) & if it fits well with your Vision & Mission 5 2 34. 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. Collective6. Present this in your Design Portfolio! The objective is to create systems that are ecologically sustainable, economically viable, that satisfy needs, dont exploit or contaminate & that are self-sufficient in the longer-term.
  7. 7. COMMON HERITAGEEnergíes coming into our Forests, water, soils, air, seeds … 0) cause pollution if NOT system – used, all our junkSun, wind, rain, people … PEOPLE work 1) INCREASE by modest use, CLASSIFICATION - For analysis of USE - RESULTS Cut-&-come-again salads, information, creativity ENERGY ACCOUNTING living components And technology 2) UNAFFECTED by use Returned water (hydroplant),well managed ecosystems, a view, good climate … Some RESOURCES are Useful Reserves 3) DISAPPEAR/ DEGRADE ifneeded RESOURCES Too much = pollution not used waste water, crop failure, fish-escapesto keep the trade 4) REDUCED by usesystem Use 4 y 5 only natural forests, coal, oil, poorly- to create managed marine and forestrySurplus = YIELD conserve resources infrastructure 5) POLLUTE if used pesticides, nuclear, oil, scorn, contempt ... Managing resources - regulate all uses to create a sustainable harvest
  8. 8. A sustainable system produces all the energy and resources that it needs for its maintenance and growth.physical What remains is the “harvest” Legal / social administrative Input energy < Maintenance energy + HARVEST biological cultural spatial “HARVEST” of a system is theorically unlimited - IMAGINATION - temporal Considers „upstream costs‟ (input enegy) & „downstream costs‟ (e.g. health) Cicles technical Niches in time “catching the flow” ENERGY ACCOUNTING preservation (Sustainability)
  9. 9. physical Legal / social administrative biological e.g. Short-Life Housing Coops cultural spatial “HARVEST” of a system is theorically unlimited - IMAGINATION - - Legalization of squatters - temporal lots of alternative people together! Input energy < Maintenance energy + HARVEST technical A sustainable system produces all the energy and resources that it needs for its maintenance and growth. What remains is the “harvest” preservation
  10. 10. “May you live in interesting times” see class 5.10 we are destroying 200 species per day - all being designing with Myth The tranformed to human biomass extinction of External biodiversity right now are alive 3/4 of the 65+ year olds that have ever & lived. A fundamental problemCollective the gray wave of the 21st century.moves ALL the other 2000 CLIMATEquadrants PETROL PEAK 2020 CHANGE monetary instability & in the last 20years, the 500 the information largest firms in the world revolution ... things are a lot more increased their production & sales by 700% whilst REDUCING interesting than we their labour force usually imagine ...
  11. 11. Can we INCREASE in Complexity while LOWERINGenergy consumption? Only if we become MORE intelligent :) ... & fast... hystorical transitions are accelerating
  12. 12. Take into account ALL these factors!BioConstruction vs. PermaConstruction DesignIs born from a personal Is born from a motivation or institutional wish real social need M2 (M2.3) Resources“Natural materials” used Materials used following Resources Scale Scalefollowing whims, trends… M2.5 y M4.2 Ethics & Consumist culture Activist culture Principles M1 y M5

  14. 14. 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. Hórreos in Galicia, Spain Vernacular architecture: localized needs & materials reflect local traditions evolves over time reflects environmental, Swiss Chalet cultural, technological, in the Vaud Alps & historical contextAnimals downstairs, warm floorStraw upstairs, warm roof Cool & DrySnow protection Rodent protection Cave houses in Granada, Spain Cave effect: warm in winter & cool in summer
  15. 15. Most of house underground: high insulation High thermal mass easy to heat in winter Shaded in summer (also with plant shade) Summer sun Isolating coverThermal Winter mass sun Atmospheric temp soil layer Thermal mass Intermediate temp soil layer Constant 14ºC soil layer

  24. 24. Transforming Rubbish Needs lots of imagination ... & personal growth (apparently) into DreamsHelp us invest in a healthier world for the future generations
  25. 25. A Big Challenge for All of Us Urgent social need❖ 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
  26. 26. The Plastic Problem Urgent google Great Pacific Garbage Patch environmental need❖ Soft plastic and plastic fibers‟ decomposition time is between 20 & 50 years❖ Hard plastic‟s decomposition time is ❖ Two huge floating plastic dumps, more than collected by Pacific currents 500 years ❖ Bigger than the USA in area
  27. 27. The Plastic Problem Health, environment, social problem… dump in Graciosa Island - Canarias❖ 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
  28. 28. Let‟s TransformPROBLEM ... Beyond Recycling ... into SOLUTIONwith some compassion, creativity & imagination
  29. 29. The Resources Scale is a tool used in Permaculture Design 0) cause pollution if NOT used, all our junk ¿Which ❖ We always 1) INCREASE by modest use, use the Cut-&-come-again salads,Materials & highest information, creativity possibleResources types in this 2) UNAFFECTED by use Returned water (hydroplant),well managed ecosystems, a view, Resources good climate …will be used Scale that… 3) DISAPPEAR/ DEGRADE if in a really (classified by use consequence) not used waste water, crop failure, fish-escapesSustainable These > > > > > > 4) REDUCED by use natural forests, coal, oil, poorly- managed marine and forestry Society? ONLY if highers can’t be used & to create structures resources 5) POLLUTE if used pesticides, to harvest the others, the nuclear, oil, scorn, contempt ... most sustainable resources
  30. 30. We Create “Hobbit Domes” "Creating the future environments: where it‟s possible to live WITHOUT generatingrubbish, recycling everything small (for 1 person or mini-homes in couple) a new EcoVillage in the Canaries 95% rubbish: plástic, cardboard, newspapers & tires iron support super-isolated from cold and heat & very cozy when plastic is protected from heat light & the weather, it stays inert, hygienic & long-lasting
