A New Journey Begins


A New Journey Begins

Picture us…lost on the barren wasteland through a cold wet December on a yet to be established living roof, situated somewhere between the solar hot water evacuated tubes and the bank of 16 solar PV panels on our roof.  Ann and I were about to set camp… for a month.  Yup, that’s right, we were going to OCCUPY our roof top equipped with our tent, our home grown food, and our composting toilet bucket from December 1 all the way through Consumptionmas (Xmas) till New Years day.

At the dinner table Emily cringes her eyebrows, cocks her head to one side and asks “Your going to do what?”  Parker shaking his head with a look of great concern resembling a parent upon hearing of their child’s wish to climb Everest… naked…asks “Why?”

Why?  Complete helplessness!  Pissed off!  Sad!  Angry!  Frustrated beyond words trying to make a difference the conventional way via slow incremental change (committee).  Passionately wanting to make a statement, (not that living in a mud house and shitting in a bucket doesn’t), but in respect to the movement to occupy for the change from a corrupt political and economic system, to occupy ‘reality’… not the illusions and distractions that entertain our culture, to occupy truth and fact and to dismantle the false arguments that sustainability is too hard – too expensive – too inconvenient.

The Scar next door (it is now 3 times bigger)

We wished to spend our month to speak truth to the failings of a growth based economy, corporate capitalism, greed, self-gratification, ecological destruction, political dysfunction, regulatory failure… all of which we can see from our roof.  We wouldn’t have to go far with our solar powered video camera to blog on it.  Just peak over the edge of our roof to see the thousands of trees gone on Goodwin Farms, and see what 10 months of dumptruck loads of fill look like (one day there was 120 dumptrucks, but even being conservative at 50/day for 8 months equates to 9600 loads of fill), entombing millions of life forms from bees, birds, fungi, ants, frogs, plants…  and the wetlands which is the local ground water recharge and spring mating ground for countless species; and this all being allowed under the watch and the rules and regulations of our municipality and province.  No Laws were being broken.  Well, the laws are wrong.  This is after all what land ownership means in our culture.

Nature has no rights…it is simply a thing enslaved to those with rights.  Here is a link to a Bioneers program talking about how 12 municipalities in the US have granted rights to nature.  http://www.bioneers.org/radio/series-archives/2010-series/earth-justice

Most of us could point to countless violations of nature which demonstrate the crazy extraction of anything, at any price for the benefit of a few, with the real cost yet to be paid.  Place these actions alongside the efforts for our community whose has produced a remarkable ICSP (Integrated Community Sustainability Plan) that is entirely aspirational… a great plan sitting on a shelf.  Here’s the link. http://www.highlands.bc.ca/sustainability/

Just imagining what Fox news north or the CBC would report on.  “Couple who recently completed building mud house, and whom compost their own BLEEP decide to move to their roof in December.”  The reality is that most of the country would just see the entertainment value of the two eco-freaks, unaware of the reason.  No impact, no information exchange… just two damp cold people more miserable than before, self abusing themselves for the entertainment of the sheeple (sheep people).

What are two conservation minded science nerds, with passions for local food, nature, solar technolgies,  policy, and green building supposed to do?  Well the first step is to not OCCUPY the roof, but rather OCCUPY ourselves.  You might argue that being occupied with a task, a project, will stop the ghosts from haunting you, and Chris Hedges would argue that it is merely more distraction supporting ones illusion… or delusion.  But what if you occupied yourself stirring the pot of Sustainability Soup.  What if you dreamt up a project that in its very concept would fit every aspect of the desires of the Municipal OCP and Sustainability reports, but broke all the “current” rules?  Now things are getting interesting.

Lower Garden Site (permaculture gardens and small Living Building Dwelling)

Imagine for a moment if two people decided to build an affordable dwelling on impacted land, where resources were shared between buildings and ecosystems, where the building needed no combustion for cooking or heating.  Where the house produced ALL of its own energy and water, with no waste, and that attached to the house was the creation of food gardens 10 times the floor area of the dwelling (also on damaged land).  What if this home like its parent (the Eco-Sense Home) had zero carbon footprint, and actually contributed to the community by providing local food, and the occupants could rely less on a car.  What if this building met all 7 petals of the Living Building Challenge, and the very creation of this building led to municipal policy changes to allow such.  Our home is about the reproduce!

Lets face it… a project such as this would make great media.  So pro-active, a model of extreme affordable modern sustainability, a model of all the concepts cities and towns are trying to implement, situated right here beside an ecological disaster.  See map.  Even better would be the stories if the project was stalled and thwarted by a political system that although supports it on paper, disallows it as it is not legal.

Ann and I have decided to push and drive policy by ‘doing’, in an attempt to create the most appropriate example of sustainable community land use planning in the CRD, with the limited funds, skills and knowledge we have at our disposal.  Surely enough if we can do it, then anyone with more means shouldn’t be scared of it.

The new policy we have written by the way… is derived from our idea of the Net Zero Zone, and rather than create a new zone, we have written a policy for an attachment to the property called the NZAD (Net Zero Additional dwelling).  The details of the policy are presented in this PDF. 20120103 NZAD letter

Humans are purveyors of myths to attach meaning to what at times seems meaningless.   We are entering a critical time symbolized and enshrined by the Northern Gateway and Keystone XL pipelines attaching the dirtiest of oils to the veins of the culture, pumping heroin into the addicted as our entire cultural myth is unraveled.  The criminal gang pushing this symbolizes all things wrong with our current cultural story.  It shines light on a political system that no longer functions as democracy but as a vehicle for corporations to achieve their desires to extract monies from all those whom have come to believe that money in its very existence is real rather than just a monetary concept that was designed as a tool of trade.  It exposes the huge dichotomy of power, politics and greed from ecology and natural systems, from which natural resources are ripped away.  The pipelines are the divining rod where first nations, climate scientists, fisheries, naturalists, natural capital economists, youth groups and small towns have a platform on which to unite and actually put their lives on the line against big environmentally irresponsible monsters.   This pipeline, the oil tankers on our coast, oil sands, climate change issue makes our blood boil….

The unraveling of our present myth, is lending to the beginnings of weaving new stories and new creation mythologies to provide new meaning to something that is now being exposed as having no meaning.  Excellent talk by Michael Mead here (Bioneers) http://www.bioneers.org/radio/series-archives/2010-series/why-the-world-doesn2019t-end

So there you have it.  Welcome to 2012.  It’s going to be very interesting watching much of our civilzation unravel and a new reality emerge.  We all play a role in what that new reality will look like.  Time to get busy…VERY busy.

We will be blogging regularly with our Progress on the NZAD.  Time line so far:

  • Dec 3rd, 2011 corresponded with Jason McLennon from the Living Building Challenge.  Jason is very excited and supportive.
  • The process began on Jan 3rd, 2012 when we officially sent our policy request (see link) into the district of Highlands.  We hope to be on the next council agenda.
  • Jan 6th, we met with Highlands building official.
  • Jan 8th we started resurrecting the old pond (for irrigation water and Net Zero water).
  • Jan 11th started preparing the lower garden site – extensive permacutlure gardens (we have rented a small bobcat)

We’ll keep you posted.

Quick notes:

  • We will be presenting on solar energy on Feb 22nd at 7pm at the Calib Pike Heritage site in the Highlands.  Judith Cullington (from Colwood) is also presenting.  All welcome.
  • Newest Island Gals is out.  Ann’s writes on climate change, how bad it is, and what we can do about it.  see www.islandgals.ca to learn where you can pick up a complimentary copy.

Affordable, Sustainable Homes: Eco-Sense and the Future of Green Building


Here is link to the Cascadia report on Eco-Sense.  One year Research Project funded by a grant from Vancity and the Real Estate Foundation.  Gord and Ann have over 425 hours into this…250 of which was volunteer…we missed our summer.

Affordable, Sustainable Homes: Eco-Sense and the Future of Green Building  (Written for the public.)

Also a link to the Technical Report  which served as the basis for the Cascadia report.  Written by Gord Baird, Christina Goodvin of Goodvin Desgins, and Ann Baird.  Lots of graphs, tables, and building science analysis for the earthen walls in four seasons (temperature, humidity, dew point),  full technical analysis of sustainable energy systems (solar PV, Solar Thermal, wood gassification), full policy report, full water analysis (grey water, rain water harvesting, composting toilets, water balance tables, and more).

See research page on blog  for all the individual reports (water, solar PV, building code, wall performance, and energy comparison reports)

January 2011 Eco-Sense Update


We’ve been saving up our words and this month we have two updates…the first is a very newsy update with short snippets and photos of what is going on here at Eco-Sense.  The second update is probably our longest and most thoughtfully assembled group of words describing what Wisdom means to us…this is a compilation of our deeper thinking on the world and how humans are fitting in.  We use our thoughts on Wisdom to explore what Less Life Stuff, More Life Style is really about and how we personally are getting there.

So here goes with the newsy bits…

Simplifying: In order to keep on track with living what we call a reasonable life with Less life Stuff, More life Style, we have both decided to pull back a bit on our outside commitments.  We have so much passion and energy that we get ahead of ourselves sometimes and get way too busy…hence burn out.  The first sign was that a couple months back our car insurance expired…and we didn’t notice for well over a month.  Oops!  The second sign was a trip to ECO-therapy to help us keep our lives on track.

Our paddle Honeymoon May 2005

The good news is that we are still very much in LOVE, and have excellent communication skills…we just need to make sure we get our downtime to recharge our batteries.  Gord has said that our life has kind of been like that of a drug addict where every time something great happens in our world we are excited and up…and then we crash…until the next fix.  So, Gord and I are learning to say No, and to tune out just a bit from the constant bombardment of negative news…you know, floods, fires, droughts, famine, collapsing eco-systems, greed, apathy, ignorance, dying oceans, melting glaciers…you know all that minor stuff the mainstream culture seems to be ignoring.  So here’s to a new year focusing on our success, spending time together, enjoying nature, and living our simple and rewarding life.

Greenhouse: As part of our own projects we are building an earth sheltered GreenHouse.  This will enable even more of our own food production.  It will even be tall enough for a lemon tree and have space to grow some tea plants.  Gord is really enjoying the project.  It is sure to be very beautiful and functional with the built in cob seating and cob oven on the North wall facing our house.  We will post photos as it evolves.

Wall Temp during sunny sub zero weather

 

House performance: In one word WOW…and we have the data to prove it.  All those sensors in the cob walls are telling a story.  This is a story about how R-value (insulation) and Thermal mass (heat storage capacity) are related and how they work together under different conditions.  Check out these graphs.  Our mass walls are also coming in at R24.

Policy: As many of you know we have become quite the policy nerds.  Last year we wrote a full report on the  barriers/policy ideas for our experiences building out home.  This full report can be found here.  As part of the research on our home funded by Vancity and the Real Estate Foundation, Cascadia is in the process of writing a full case study on the home including the barriers.  All the research, tours, publicity, and recent Living Building Challenge Petal award has resulted in yet another high level policy tour here at Eco-Sense organized by our MLA John Horgan.  John arranged to have the new provincial Minister of State for Building Code Renewal, Naomi Yamamoto and her Assistant Raechelle Williams tour our home to learn about our experiences building the “World’s Greenest Modern House”.  See this link to read our thoughts after this meeting.

John Horgan (MLA), Gord, Ann, Minister Yamamoto

This was not the only higher level Government attention that we received in the week before Christmas.  See this link for a very nice letter we received from MLA John Yap, Minister of State for Climate Action.

John Horgan:  John has been very supportive of our work here at Eco-Sense over the years right from his first tour in 2008 before our home was finished.  This tour inspired him so much that he actually got up in the legislative Assemble to discuss our home.  Here is the Hansard minutes from April 10, 2008 with his speech. http://www.islandnet.com/~anngord/downloads/legislative-report-april10-08.pdf

This visit was the first of many over the following years.  We always found John very knowledgeable, practical, approachable, and highly principled.  John recently attended our big party to celebrate the announcement of our Living Building Challenge award, and has really gone to bat for us with bringing awareness to some of the barriers we have faced with building and living sustainably especially when it comes to energy policy.  John gets it and has an excellent grasp on current reality and the challenges faced and the steps required to move forward in this rapidly changing world.

Our Two Eco-Cents…we support John Horgan for leader of the NDP and for the next premier of the province.  We are generally non-partisan and vote for people not parties.  If you are so inclined to join the NDP to vote for John Horgan as the parties new leader, you must be 12 or older, and pay $10.  You’ve only got one week…to join!  Talk about making your vote count.   We sincerely hope that John Horgan can shape the politics of this province so that EVERYONE (Green, NDP, and liberal views) can work together to focus on the issues and not the politics.

BCSEA Webinar: Also in Dec…the same week everything else seemed to happen around here, we put on a webinar organized by the BCSEA to do a virtual tour of our home to 200 registered participants across BC.  It was a lot of fun as we breezed through over 100 photos of our life and our home telling our story, bantering back and forth, discussing policy, showing energy graphs, etc.  We then took questions for about 20 minutes.  This link on the www.BCSEA.org site allows you to download the slides for the presentation with audio coming sometime in the future.

HSTF, WCS, SSAC, ICSP. Ok, the acronyms are starting to be completely unsustainable in my mind.  Ann served a one year term (2009) on the Highlands Sustainability Task Force  (HSTF).  This full report containing all 42 recommendations is on the Highlands website at http://www.highlands.bc.ca/planning/documents/SustainabilityTaskForce_FinalReport.pdf.  The District of Highlands has brought the Whistler Centre for Sustainability (WCS) on board to help with implementation of these recommendations.  So another committee, the Strategic Sustainability Advisory Committee (SSAC) has been formed to guide the WCS in creating the  Integrated Community Sustainability Plan (ICSP).  Sounds complicated, but it really is a fascinated process as we navigate through the recommendations and create the tools to actually implement the recommendations within a municipal context.  By mid 2011 it is hoped that the OCP will be updated and the Highlands municipality will have a long term community plan to move our community forward.  For me it is very exciting to think that our Eco-Sense ideas of Flush Toilet Ready, Net Zero Zones, carbon offset payment for new construction, energy and water conservation/incentive programs, and no net increase policies for energy and water could be policy or even written into the OCP…and these are only 4 of the 42 recommendations being implemented.

Mary Lake: The Highlands is definitely leading the way with many aspects of sustainability…including that fact that over 39% of our land base is park.  And for those who have not heard the news, a group of passionate volunteers from our small community are working their butts off to create another park, 107 acres around Mary Lake.  www.saveMaryLake.com

Mary Lake

This land consists of mature low lying Douglas Fir ecosystem, with wetlands, two creeks, and a lake.  The Save Mary Lake volunteer group launched a social media campaign headed up by Bob McMinn (86) who has been absolutely relentless in keeping our dreams alive.

Bob, our inspirational leader

This land is an essential nature corridor that connects Thetis Lake park to the Gowlland Range.  Please check out this video of Bob to fully experience the importance of this land for everyone.   http://www.savemarylake.com/contest/

Bob hiking Gowlland Range at 86 years old

Imagine being able to hike right from Victoria to the Gowlland range…ocean to ocean on beautiful trails.  Mary Lake is the missing link.  You can help for just $10 on the interactive map and pick your own personal square meter to save and dedicate.

Spell the word FROG in a wetland with your square meters

Save square meters to spell the word LOVE

The campaign is very unique and fun…Our family is creating a family tree where we have all saved square meters on one old growth tree…right near a very old log cabin that it is rumoured that Emily Carr stayed.  The campaign to save Mary Lake has just got a lot more interesting too…with the launch of a contest called “The Power of Many” to win up to $10K by creating your own utube video to convince people in your life to help save this amazing land.  All donations will also receive a tax receipt from the registered charity with my signature as I am the treasurer doing my little part behind the scenes.  I would personally like to thank the others on the front lines (the BRAINS) of this project; Bob, Greg, Neville, Pattie, Rod, Koi Neah, Dustin, Libby, Eric, Ellie, Rob, and many others….especially the visionary group on the Highlands Stewardship Foundation board who pulled out the Scotch after our last meeting.  I don’t think Gord wrote that into the minutes.   Here is an awesome link to some photos and slide show (of the lake…not us drinking Scotch)…enjoy!

So, there you have it..a VERY quick update to see what’s happening in Eco-Sense land.

Hugs from Ann and Gord

Arcade Journal – Rainwater Collection


RAINWATER COLLECTION

A Simple Path to Responsible Water Use
(excerpt from Arcade Journal – Winter 2009 – guest editor Jason F.McLennan)

——————————————————————————–
Ann and Gord Baird
——————————————————————————–

Incorporating biomimicry into environmental design, whether commercial or residential, combines beauty, simplicity and function into responsible use. With that said, the natural world abounds with examples of simple rainwater harvesting. Lakes, ponds, wetlands and groundwater are excellent large-scale, natural examples of rainwater harvesting, while upturned leaves holding droplets serve as micro examples. Architectural expressions of natural systems for capturing and conveying the rain that falls on our sites can be inspiring and add significant meaning to any design. Storing rainwater for future use is a natural, life-supporting process that has been absent for much too long in modern building design.

However, times are changing, and we are increasingly cognizant of our abuses of the world’s water. By installing rainwater harvesting systems, the water that is industrially treated is reduced, contributing to individual and community water security and maintaining balance in the natural water cycles of surrounding ecosystems. The impacts of rainwater collection — a simple process — can be profound.

Rainwater can easily be used for many purposes including irrigation, flushing toilets (which accounts for 30% of indoor water use), mechanical systems, cleaning needs and even potable drinking water, but conservation should always be considered first so that water requirements are reduced.

A Guide to Rainwater Harvesting

A basic system collects rainfall from the roof, filters out debris and then stores it in cisterns; storing clean water results in less tank maintenance down the road. The stored water can then be drawn upon and filtered further as required depending upon the use. It is critical to match the appropriate quality of water to its intended use.

Roof materials, gutters and slope all have their pros and cons. Metal, clay tiles and slate are great, but better yet, consider a living roof, which among many other benefits also acts as a mini-watershed for primary filtration. A living roof also has built-in drainage layers, thus reducing or eliminating the need for exterior gutters.

A first flush diverter is required to discard the first seasonal rain that falls on a non-living roof to clean-up the pollen, bird poo, needles and leaves. There is usually a secondary simple filter (screen) for leaves and other sedimentary materials.

Tanks are literally a big topic, and their size is determined by three factors: roof size, monthly/annual rainfall and monthly/seasonal usage. Cisterns can be concrete with a sealer or membrane, wooden, metal with a membrane, HDPE plastic tanks, ponds or wetlands. Ideally, as with any system, it is important to incorporate biomimicry and consider all the household systems when designing. For example, a large, concrete cistern can be incorporated in the foundation of a home, simultaneously adding a temperature moderating thermal mass, providing a possible dump for solar thermal heat and a water reservoir for fire protection. Your climate, site, budget, other systems and environmental leanings will determine your choice.

Stored water can be used for potable or other uses; non-potable usage does not require any further filtering before it is used but should be marked as “not potable.”

Potable water needs to be filtered or sterilized to meet local code requirements. Usually rainwater will be filtered down to five microns before sterilization. Possible filters include sand, ceramic and disposable. Once adequately filtered, the water can be sterilized to kill any potential pathogenic bacteria via a UV sterilizer, a chemical sterilizer (such as bleach) or a membrane osmosis system; the choice depends on many factors, such as regulations and energy requirements.

What about code? Since policy can be lacking in many jurisdictions, common sense dictates having your water lab tested for potability. (For more on water regulation, please see Ben Gates’s article “Taking the Guerilla Out of Greywater” later in this issue .)

If energy conservation is vital when processing rainwater (as it is at our home), use mother nature’s pumps (gravity) wherever possible and then only special energy efficient pumps. Pump choice is based upon the desired pressure, the amount of head it has to travel (distance straight up) and the volume of flow.

Take for example our vegetable garden’s drip irrigation system. We have a 2,500 square-foot living roof that collects 1,300 gallons for every inch of rainfall; 1″ of rain on one square-foot of roof area produces 0.52 imperial gallons. Precipitation occurs during winter, so we store enough rainwater for four to six months of summer drought. Our storage capacity of 10,000 gallons consists of four tanks, all gravity fed to overflow to the next, thus eliminating our need for a separate stormwater system. Our domestic potable water comes from a deep well, and we utilize a no-flush toilet and low-flow fixtures to reduce our domestic water use. The rainwater system is designed for possible future upgrade to potable quality by installation of a sand filter between the living roof and the storage tanks and then through a five-micron ceramic-filter and UV sterilizer.

Larger scale examples consist of basically the same steps. Keeping systems simple and fully integrated into the building design is the key to water sustainability.

Nature can be our friend or our enemy. If we design with the natural environment, rainy, grey days are sources of joy and renewal, as we watch our vessels fill with the most precious of all resources: water.

Rain Water Harvesting for Drylands and Beyond, by Brad Lancaster

Ann and Gord Baird walk the talk of sustainable living in their newly completed (Dec 08), multi-generational, Eco-Sense home that is registered for the Living Building Challenge. The couple’s passion and knowledge is expressed in their work consulting, building and advancing policy, and in the hundreds of tours they have given of their home. They teach that if it isn’t affordable, it isn’t sustainable and live their motto, “Less life stuff…more life style!”
