Workshop Agenda• Permaculture Design Principals• Edible Landscaping• LED Grow Lights• Solar Greenhouses• Living Walls and Rooftop Gardens• Social Enterprise• Urban Homestead Design
Permaculture = "permanent" & “culture."Its roots evolve from• the design of sustainable agricultural systems,• techniques and principles of ecologically designed communities,• urban restoration and self-reliant regions.in such a way that all life benefits (i.e. human and non-human).
Permaculture Ethics and Guiding PrinciplesPermaculture Ethics• Care of land;• Care of people;• Reduce consumption and share surplus.
Principle 1: Ethics, care of land and peopleCaring for the land,people and all lifewould be astep forward for all.
Principle 2: Relative locationThe strategic selectionand placement ofplants, animals,structures, etc., so thatthe yields of oneelement becomethe requirements for What does the chicken produce that can be used by other elements in the design?another element
Principle 3: Multiple functions, single elementEvery element shouldprovide at least threefunctions.• A "living" fence can act as a barrier, act as a windbreak, and provide food and medicine for the family.• When designed into a system, bees can provide; food, income, and pollination.
Principle 4: Multiple elements, single functionMultiple elements for a singlefunction adds diversity and makesthe local ecosystem moreresilient to environmentalfluctuations.For instance, for heating a structure,the elements would include:• body heat from animals,• south facing windows, and• the use of thermal mass to store the collected heat.
Principle 5: Efficient energy planningThe goal is to help reducethe amount of effort(primarily human labour)The property is divided intozones related to howfrequently each zone is visited.The more intensive the activitythe closer to human habitationit should be.
Zones and Sectors Sectors take into• Zone Zero - Home consideration the• natural elements and Zone One – Home Garden wildlife.• Zone Two – Home Orchard• Zone Three – Farm• Zone Four – Managed Forest• Zone Five - Wilderness
Principle 6: Biological resources• Move away from monocultures.• Mimic the diversity and resistant qualities of natural systems.• Focus on utilizing energy flows (water, wind, etc.) that pass through a region.
Principle 7: Energy recyclingEnergy flowing through thesystem is used in many ways.• Water systems might create keyline swales and dams as it passes through the landscape.• Energy recycling would also include recovering biogas from waste and orientating structures to obtain maximum solar gain.
Principle 8: Maximize diversity• Build stability by maximizing diversity, in terms of plants animals and in terms of livelihood.• Maximize the number of beneficial interactions• Create as many microsites, and habitats as possible by increasing edges, patterns, and plant guilds.
Principle 9: StackingStack elements in verticaland horizontal space aswell as in time to grow asmuch as possible in avertical plane so largerareas of land can beput back into a morenatural state in the hopeof healing the planet.
Principle 10: Appropriate technologyUse implements that are E.F Schumacher,locally made, can be ‘Small is Beautiful’repaired locally, and usedwith the skills of localpeople.Also, have less reliance onfossil fuels.
Principle 11: ScaleReturn to smaller scaletechnology and a balancewith technical diversity.http://www.ferrari-tractors.com/smallscale.htm
Mollisons 7 Permaculture Laws• (1) Everything is connected to everything else.• (2) Everything gardens.
Mollisons 7 Permaculture Laws(3) Yield of a system is theoretically unlimited. Limited only by the imagination and experience of the designer.(4) "Protracted and thoughtful observation, rather than protracted and thoughtless labour."
Mollisons 7 Permaculture Laws5) The problem is in the solution, or everything works both ways. Problems turned into assets and wastes into resources.(6) Stay out of the bush; it is already in good order.
Mollisons 7 Permaculture Laws(7) Work with nature instead of against it.

Solar Greenhouse Rules of ThumbDesign:•If the greenhouse is longer than 16ft., the East and West walls should besolid.•For maximum solar heat gain, the glazed, south side should be tilted to thesame degree latitude you are located at, plus 15 degrees.•For maximum solar benefit on plant growth the glazed, south side should betilted to latitude plus 5 degrees•Snow can reflect 50 more total radiation through a vertical wall than a tiltedwall can transmit.•The angle of the north roof should approximate 30 degrees to reflect lightdown on the inside.•There should be a double doorway/vestibule on the main entrance if thegreenhouse is not attached to another building.•Insulate with R-20 in the walls and R-40 the roof.
Solar Greenhouse Rules of ThumbFoundation:•For a greenhouse less than 300sq. ft. should be attached, a pit or dug intothe side of a hill.•The floor in a five foot deep pit (no wider than 12ft.) will average 40-50degrees Fahrenheit, year round; providing warmth in the winter and coolingin the summer.Glazing:•Glazing should equal at least 1/4 of the total floor area.•R-12 insulation over the glazing for 14 hours will reduce the buildings heatloss by one half.•The south wall should be double glazed.•The east and west walls should be a triple glazed.•The north wall should be insulated and painted white.
Solar Greenhouse Rules of ThumbHeat Storage:•Choose building materials that absorb heat quickly.•Use as much storage as possible.•Use at least 1/2 cubic foot of stone or 4 gallons of water/sq.ft. of glazing•Insulate the perimeters of the foundation.•If it gets above 90 degrees in December, January, or February morestorage is needed.•Provide heat storage directly below plants.•Rocks 3/4 of an inch to 1 1/2 inches in diameter are most suitable forstorage bins.•The surface area of the storage should be at least equal to the floor area.Location:•The greenhouse should face within 30 degrees of true south.•No obstruction as tall as the greenhouse should be within 4 1/2 times theheight of the house.•Provide a wind break on the north side with trees, buildings, or hills.•If the floor area is less than 200sq. ft., the greenhouse should be attachedto another building.
Solar Greenhouse Rules of ThumbPlant Care:•If the greenhouse faces 15 degrees east of south, it will benefit plantresponse to light intensity.•Red and blue light from painted walls will promote healthy growth andearlier flowering.•Plants prefer fluctuating temperatures from day to night.•Water once/ day during summer and once/ week during winter.Solar Heat Benefit:•During the day a greenhouse can put excess heat into an attachedbuilding heating an area over twice its own size.•A greenhouse will raise the humidity of an attached structure about 5percent.•An attached greenhouse is usually cooler than a freestanding structuresince 10-15 percent of the suns radiation is blocked by the adjoiningstructure.
Solar Greenhouse Rules of ThumbVentilation:•Vents should equal 1/6 of the floor area with uppers of 1/3 larger than thelowers.•Fans regulating air flow should circulate four(4) cubic feet per square foot ofglazing per minute.•Low vent windows should swing open at the top to aid thermo-circulation anddeter low flying insects from entering the house.•Upper vents should be located along the upper ridge or on opposite side wallthat a lower vent/door is located.

Social Enterprise inthe Age of Responsibility
Key Principles in the Age of ResponsibilityConsidered Design- Less energy, less waste, reusable resources•Eliminate Waste,•Generate Benign Emissions,•Use Renewable Energy,•Close the Loop on Production,•Use Resource Efficient Transportation,•Sensitize Stakeholders,•Redesign CommerceLife Cycle Assessment and Biomimicry
In the Age of Responsibility the company contributes to and becomes part of the community. It is not just something to invest in or work at. It is something to believe in.
