The Eye of the Wind

I’m on vacation visiting family in Vancouver, British Columbia and had the rare treat to go to the top of a wind turbine on Grouse Mountain.  The 1.5 megawatt turbine provides about 25% of the electricity the mountain needs to operate, and it makes a beautiful, powerful statement on the top of this urban ski mountain.  Wind power reduces waste from dirty sources of electricity production, and is driving new jobs and economic development.

But the owners of Grouse have taken it one step further, and installed a custom-built, glassed in viewing pod at the top of the turbine – The Eye of the Wind – the world’s first elevator-accessible viewPOD.  For $25, you take an elevator to the top and take in spectacular views of the city, ocean, and surrounding mountains.

The thrill of some slight vertigo along with the chance to learn all about wind power and see the area from a really unique perspective makes it well worth the price of admission.  One section of the floor is see-through glass, and demands some courage and faith-in-engineering to step on.

Each pane of the glass wall has some fun-facts about how the turbine works and the local area.  A flatscreen provides real-time data about wind speed, electricity generation, carbon avoided, etc. (unfortunately the wind wasn’t blowing at a sustained rate of over 9 km/hr while we were there, so the blades weren’t turning, and they’re still addressing the final hurdles before they can tie in to the grid).

Grouse rents out the pod for corporate functions and the like, and have done a great job of maximizing the value of their wind turbine.   The turbine was built by Leitwind out of Italy, a division of the company that builds some of their chairlifts, and the pod was custom built using components from 10 different countries.

While the folks back home in Massachusetts, have been arguing over the impacts on tourism of the Cape Wind project, this project pushed ahead and has shown that turbines themselves can be a revenue-generating tourist attraction.  I’d sign up right away for a boat tour through the first offshore wind farm in the US – not only to see those beautiful turbines up close, but to be a part of history, experiencing the early steps of creating a safe, independent, clean energy system.

Biomimicry in the Mainstream

On Sunday, the Boston Globe ran a piece titled “It’s Alive!  How closely can a building emulate nature?” giving some solid, mainstream attention to the concepts of biomimicry and regenerative design as well as the Living Building Challenge.

Omega Institute for Holistic Studies (source: Boston Globe)

The article references one of my favorite biomimetic examples, the termite mound:

In 1996, a landmark project was completed: the Eastgate Centre, a large office building and mall in Harare, Zimbabwe, designed by architect Mick Pearce. Modeled after termite mounds found in the region, the building has no air conditioners, yet stays cool through a ventilation system inspired by nature. Termites perpetually dig (and plug) holes to catch breezes and modulate the temperature within their mounds. Using fans, vents, and funnels, the Eastgate Centre mimics this system. It uses 10 percent of the energy of buildings of similar size, and was estimated to save $3.5 million on energy in the first five years of operation.

It’s a great example of how smart design can save lots of money and dramatically reduce energy demand.

The article also provided a nice update on the latest status of the Living Building Challenge – still no certified projects, as they need to be monitored in operation for a year, but three are expected to pass the test this summer.  Seventy have been registered – which is a great sign that momentum continues to grow and pull the leading edge of building design towards truly sustainable, restorative practices.

Another exciting bit of news from the article:

The global architecture firm HOK has established a collaborative relationship with the Biomimicry Guild, working with its biologists. Plans for a project in India, to design a city, include rooftops that imitate the “drip-tip” structure of a local fig leaf; this structure encourages the rapid runoff of water, essential during monsoon season. British architect Michael Pawlyn is working on a greenhouse in the Sahara desert that desalinates seawater, inspired by the Namib Desert beetle, which manages to survive by catching water droplets from fog on its shell and funneling them to its mouth.

This is a great development – but we’d love to see some projects in the US as well, where buildings are responsible for almost 50% of our energy use, and approximately three-quarters of our electricity use.  Biomimicry in building design is a massive and critically important component if we are to dramatically reduce demand (on the order of 90% like in the termite example) so that we can meet the remaining demand with 100% clean, renewable energy.

University of Illinois – Backcasting from a Sustainable Future

There are many ways to think about and articulate the concepts of sustainability and restoration – that is a global society where our activities don’t systematically undermine the social and ecological systems upon which we depend, and works to restore and revitalize those systems we’re currently damaging. At Aedi we define sustainability using the framework for Strategic Sustainable Development (SSD) to guide our thinking.

credit: Arising, http://wearearising.org

This approach involves imagining oneself in a sustainable future, where the four scientific principles of sustainability are not violated, and then ‘backcasting’ to the present day and asking the question “what did we do back then to get here today.”

I just wrote a post for Greenopolis.com about how the University of Illinois, and hundreds of other colleges and universities are essentially taking this approach to move their campuses, communities, and all of society towards a climate neutral, sustainable future.  (To browse hundreds of other climate action plans from colleges and universities across the country aiming to achieve climate neutrality, check out the online Reporting System of the American College & University Presidents’ Climate Commitment (ACUPCC).)

In some of their planning documents, the folks at Illinois do a good job of articulate two important components of sustainability – the first that has to do with all future generations (human and otherwise) and the second that involves the billions of people today who are already suffering dearly from our global, unsustainable systems.  They write:

“The first societal challenge focuses on the need to maintain natural ecosystem function and adapt human-dominated ecosystems to restore critical functions of natural ecosystems. Such ecosystems: (1) have closed loops (waste from any process is re-used or becomes input to another process), (2) re-use non-renewable resources (e.g., minerals), (3) use renewable resources (e.g., water and forestry supplies) at a rate less than their renewal rate, and (4) provide habitats to healthy populations of native species. Such an approach will be achieved through creative, system-level design of essential human services (e.g., food, water, shelter, energy, transportation, information, social interactions, security, and health care) that emphasize environmental as well as social and economic criteria.

“The second societal challenge focuses on impoverished communities, where a lack of essential human services, often accompanied by rapid population growth, threaten both local and global sustainability and create serious challenges to success on the first grand challenge. Better understanding of the economic, political, and social policy drivers of poverty is needed to develop creative solutions that enable citizens of these countries to sustainably develop needed capabilities, such as food and shelter, having good health and a life of normal length, and fulfilling social needs. To be sustainable, such capabilities must be supported within a diverse and equitable interdependence with economic markets, social security, government services, and political processes. This interdependence provides critical safety nets when environmental, economic, or social changes stress livelihoods.”

The structure of Aedi Group, through the co-profit model, is designed to address both of these simultaneously.  First, our for-profit companies are all set-up to work towards sustainability.  Second, our non-profit, Village Corps, aims to empower the world’s poor to generate sustainable prosperity and resilient communities for themselves.  In this way we aim to ensure that not only does our work support others around the world, but also the economic-engine for that work is not acting against those efforts by reinforcing unsustainable systems that result in symptoms that threaten the very people we would like to help.

It is this approach of imaging the future we want and working together to create it that will help us break free from the habits and systems of the past which are now (largely inadvertently) creating results that threaten billions of people and natural systems of all kinds the world over.

UAE’s Ecological Footprint

WWF has developed a great quick video about the Ecological Footprint of the United Arab Emirates – among the highest in the world (the US of course is right up there as well).  The Ecological Footprint concept is a great way to measure and communicate the ecological impact of an individual’s, organization’s, or nation’s activities.  It translates these impacts into area measurements, and shows that in total, we are using resources faster than the Earth’s biogeochemical systems can regenerate them – about 25% faster since the late ’80s.  At this point that means we’d need to about 1.4 Earth’s to support our current global economy – and of course we only have one.  The Living Planet Report from WWF and the Global Footprint Network dives into all of this in a really accessible way.

At the same time, we’re reducing the planet’s biocapacity, and thus it’s ability to generate resources and assimilate waste.  It’s scary stuff.  But hats off to the UAE for engaging with WWF and the Global Footprint Network to educate its population and look for ways to create better, and ultimately sustainable, systems:

The Danger of the Single Story

Yes, another TED Talk – but this one is not  focused so directly on our construction business.  While this topic is relevant in all of our work, it is particularly important in the work of our non-profit, Village Corps.  Here, Nigerian native, Chimamanda Adichie talks about the danger of the single story – how they can create very limited mental models and impact our perception of how the world works, often with negative impacts:
