1. Preserve Our Present, Secure Our Future, and Have Fun While We’re At It.
Destination Zero Carbon (DZC) - Junior Category is a clean energy education programme and a race confederation built around the excitement of a drag-race competition. Let DZC expose your students to the phenomenon of global warming and its negative impacts through structured questioning and a high measure of hands-on activities. Students will be introduced to the intricacies of hydrogen fuel cell technology and its relevance as an alternative and sustainable clean fuel source to fossil fuel.
See how DZC can help your school cultivate environmentally-aware individuals of the future…
Destination Zero Carbon (Junior Category) Inter-School Finals 2011 took place on 1-3 November at the Clean Energy Expo Asia 2011, Suntec International Convention and Exhibition Centre.
Day 1 Highlights:

Day 2 Highlights:
Race Day, and the excitement was palpable. Teams tested their cars one last time before the actual race. While some teams masked their anxiety believably well, others were clearly a bunch of raw nerves.

I took the liberty to interview some teams before the qualifying races. Amongst them were team buddies Mohd Hazim B Mohd Hasni and Ho Jia Jin representing Hong Kah Secondary School. When asked about Speedy’s design, the team shared that the car was conceptualized in a dream. “We chose to use discarded drink cans as they are lightweight and provided us the metallic look we were hoping for,” Hazim said.
‘Speedy’, winner of the DZC Innovation Award, was the brainchild of team buddies Hazim and Jia Jin representing Hong Kah Secondary School. The Innovation Award was presented to the team
for their car’s unique, ‘mind-blowing’ design.
The duo had heard about the competition from their school teacher and were immediately drawn to the challenge. In spite of the relatively short preparation time and the extra hours they had to put in, both were visibly glad to be a part of the DZC action.
Greendale’s ‘Sonic Duo’ and ‘Daloy’ teams were all out to win it, but they also mutually agreed that the experience had been invaluable. Cedric Khng and Wang Shih Yong of ‘Sonic Duo’ were later awarded the DZC Best Presentation Board Award for their “attention-grabbing” presentation board design and “photo-realistic rendered images” of their car.

The qualifying rounds witnessed a mixture of smooth-sailing success for some teams, and of disappointment for others. Representatives from one particular school stood out from the rest— D&T teacher-in-charge, Mr Alfred Lim, and his entourage of determined competitors from Bukit Panjang Government High School.

While fellow competitors from the other schools dealt with their share of clear-cut victories and failures to launch, the students of both teams from BPGHS cheered their cars on, refusing to give up on finishing the race, no matter what. Their efforts paid off as both their cars—‘Nightmare in the Light’ and ‘My Eco Car!’—got through to the finals.
Mixed reactions from competitors after a truly remarkable round
In a candid interview, Mr Lim said he was pleasantly surprised by the enthusiasm his students had shown in the construction of their race-cars and the effort they’d put into their race preparations. Watching their excitement over the use of the hydrogen fuel cells, he expressed his hope that this would spur enough interest in them to incorporate clean energy considerations into future D&T projects.
Day 2 ended on a high note, with a prize-presentation by Ms Sharon Toh, General Manager, South Asia, Dassault Systemes SolidWorks.

2. Ride the Sustainability Tide.
The environment as we know it is changing, largely for the worse—or so we’re told. We hear terms like ‘sustainability’ and ‘sustainable development’ being mooted in policy debates, finding its way into mainstream school curricula, and floating about those we consider to be the environmental ‘sympathisers’ amongst us. But whether or not we choose to ignore it, the concept of sustainability is in fact gaining ground. This should come as no surprise, as all across the fields of agriculture to the fields of academia, significant loss of biodiversity from human activities gone unchecked is affecting us in ways we have yet to fully perceive, much less quantify or appreciate. So before this elusive concept of sustainability threatens to engulf us all unawares, let’s give the ideal its due consideration.
Sustainability, at its most basic level, is the capacity to endure. For humans, it is the long-term maintenance of well-being. In ecology, sustainability describes how biological systems remain diverse and productive over time, which, over all, is a precondition for human well-being. The intricate relationship between humans and the Earth’s biosphere has lead to the most widely quoted definition of ‘sustainable development’ by the Brundtland Commission of the United Nations on March 20, 1987 as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
~Source: http://en.wikipedia.org/wiki/Sustainability (retrieved on 24/10/2011)
The inescapable truth is that human development is taking place at the rate at which the Earth cannot bounce back from in time to meet the needs of our generations to come. In 1992, Edward Wilson, American biologist and two-time winner of the Pulitzer Prize for General Non-Fiction, noted that human activities have increased 'background' extinction rates by between 100 and 10,000 times. The world’s coral reefs—home to over 25% of fish in the ocean and estimated to generate up to $375 billion each year in revenue through eco-tourism—have experienced 20% (irredeemable) loss and a further 20% degradation in just the last several decades alone. Experts believe that the increasingly dire state of the world’s poor is inextricably linked to the problems in our environment.
If our Earth—the only known celestial frontier wherein human life is blessed with generations of continued existence—is really in that much trouble due to our own actions, then it begs the question that should we not, ALL, feel the compulsion to do something to abate it right now?
The calls to adopt sustainable corporate practices have been greeted with reactions ranging from wholesale adaptation to casual indifference. Much of the nonchalance and/or aversion that we (in developed countries) feel towards our world going to waste can be attributed to narrow self-interest; the mantra ‘we will not negotiate our way of life’ dictates that we resist change for its own sake. It is popularly believed that caring for the environment and losing sleep over the world’s poor and destitute are the work of the few, selfless activists and academics whose sole aim and purpose in life is to answer a moral-calling born of a shared humanity.
While this belief has helped buoy the hopes of the millions affected by careless business practitioners, much of the masses have also been ‘bitten’ by the proverbial ‘green bug’. Consumers are increasingly more aware of the environmental costs of the products they buy, which has led to a growing demand for products with the stamp of sustainable design . Students—agents of social change in our foreseeable future—are increasingly coming in contact with literature that champion the sustainability cause. Governments are hard-pressed to meet international emissions standards and to keep pace with legislative must-haves if they are to continue to have a say in the world stage.
With all these players piling on the pressure to depart from the fundamentally flawed strategy of ‘develop-now-and-restore-damaged-ecosystems-later’iii, early movers have shown that embracing sustainability as a means to ‘lower costs’ and ‘increase... revenues’ may not be too far-fetched an idea after all . Borrowing the metaphor of WASTE=FOOD from a keen observation of how the forest recycles its own waste, the field of Biomimicry has yielded what has evolved to be known as the Cradle-to-Cradle (C2C) design concept. C2C design is ‘a holistic economic, industrial and social framework that seeks to create systems that are not just efficient but essentially waste free’ , and is one widely-adopted mode of operations cited by sustainable companies as the analogous phoenix that rises from the ashes. The challenge, therefore, is for companies—large and small alike—to re-think business models, be willing to innovate for the sake of a sustainable future, and to view (legislative) compliance as opportunities—rather than obstacles—to their corporate vision, mission and values.
If we opt to lull ourselves into the mistaken belief that sustainability is someone else’s problem, or that we are but one person with neither sufficient means nor motivation to heal the Earth, the good news is there’s still no stemming the tide of sustainability. Whether we choose to view it as a natural human progression (born of a shared humanity), or the product of market- and/or legislative-pressure (thereby an act of self-preservation), sustainability is here to stay. And it stands to reason that if we are to do the same, it’s about time we ride the sustainability tide.
SolidWorks takes a ‘Consumption-Management Approach’ to sustainability by offering users the means to perform environmental impact simulation on their SolidWorks designs. SolidWorks Sustainability is the first environmental assessment and sustainable design tool integrated into a CAD package. It is the world’s only tool that performs a screening level LCA (Life Cycle Assessment ) in design and engineering. It leverages on the expertise of PE International, a leader in LCA consultancy services for over 20 years. This wealth of experience in the LCA arena alongside powerful GaBi software database make SolidWorks Sustainability the world’s most comprehensive tool for quantifying the environmental performance of materials, processes, products and infrastructure. SolidWorks users can now base their technical decisions on the highly-reputable LCA knowledge of PE International.
“SolidWorks Sustainability allows us to ask the hypothetical question of ‘What would be…’ by moving the environmental impacts consideration up into the design process, rather than do a post-mortem analysis of ‘What is…’ (in-production consideration) and ‘What was…’ (post-production consideration)”, says Asheen Phansey, Product Manager of SolidWorks Sustainability & North American Sustainability Leader, Dassault Systèmes. This sentiment is echoed by Delphine Genouvrier, Business Development Manager at Dassault Systèmes (EMEA), who envisions that environmental impact considerations for choice of material will someday be a driving factor in product design, and should therefore be given the same weight as more established economic parameters.

This means making design decisions to ensure future environmental stability. Using SolidWorks SustainabilityXpress allows us to be environmentally conscious about our designs.
Metrics used to assess Environmental Impacts
This represents a measure of Carbon dioxide and its equivalents (such as Carbon monoxide and Methane) that are released into the atmosphere primarily by the burning of fossil fuels.
This tabulates the amount of non-renewable energy used from sources associated with the part’s life cycle in units of mega joules (MJ). This impact includes not only the electricity or fuels utilized during the product’s life cycle, but also the upstream energy required to obtain and process these fuels, and the embodied energy of materials which would be released if burned. Energy consumed is expressed as the net calorific value or energy demand from non-renewable resources (e.g. petroleum, natural gas, etc.). Efficiencies in energy conversion (e.g. power, heat, steam, etc.) are taken into account.
Sulfur dioxide, Nitrous oxides and other acidic emissions to air cause an increase in the acidity of rain water, which in turn acidifies lakes and soil. These acids can make the land and water toxic for plants and aquatic life. Acid rain can also slowly dissolve man-made building materials such as concrete. This impact is typically measured in units of either kg Sulfur dioxide equivalent (SO2e), or moles H+ equivalent.
When an over-abundance of nutrients are leaked into a water ecosystem, eutrophication occurs. Nitrogen and Phosphorous from waste water and agricultural fertilizers causes an overgrowth of algae, which in turn deplete the water of oxygen and result in the death of both plant- and animal-life. This impact is typically measured in either kg Phosphate equivalent (PO4e) or kg Nitrogen (N) equivalent.
Case Study: Material of a Disposable Cup
Let’s consider the humble drinking cup.
A typical disposable cup is only used once but the material used in its production has significantly different impacts on the environment.
Here, we’ll make a simple comparison between using a disposable paper, foam and plastic cup.
Open Part. Download the Part file and open it in SolidWorks. “Cup”
Go to SolidWorks Menu -> Tools -> SustainabilityXpress.
Assuming the Cup is made of Paper.
Select the following options:
Transportation & Use:
Set as Baseline.
Click on Set Baseline at the bottom of the Task Pane below the pie charts. A grey bar updates this data as Current Baseline.
Comparison with a Foam (or Polystyrene) Cup.
Edit the options below:
Name: PS Medium/High Flow
Process: Injection Molded
Click on Next
to look through the dashboard which provides real-time feedback on the environmental impact of the design in the 4 stages of its life cycle:
-Transportation and Use
-End of Life
All stages show that a Foam Cup is worse off environmentally than a Paper Cup of the same mass.
Green bars indicate the current material has a lower environmental impact than the previous material.
Red bars indicate the current material has a higher environmental impact than the previous material.
Online Sustainability Calculator.
Click Online Info at the bottom right corner and the website will be launched. The Sustainability Calculator takes the values that we found for the Environmental Impacts (CO2, MJ, SO2, and PO4) and represents them in a mode that is easier for us to understand.
Energy Consumption -> Hours of powering a laptop.
We can conclude that using a Paper Cup is relatively more environmentally friendly than using a Foam Cup, which requires 8 times more energy.
Now set Polystyrene (Foam) as baseline .
Find Similar Material.
Return to the ‘ Material’ tab and click on Find Similar.
A dialog box appears with options for choice of ‘Material Class’ and other mechanical properties.
Plastics’ for Material Class and click Find Similar.
Material Class and click Find Similar.
A list of alternative materials matching your options appears.
Choosing an alternative material (in our case, a ‘plastic’) with a more environmentally friendly design is as easy as clicking on each material name and watching the environmental dashboard respond accordingly.
Compare our foam cup baseline with disposable plastic cups made of PP (Homopolymer).
Notice that green bars appear for all the charts.
Tip: PP is one of the plastics which can be recycled whereas foam is non-biodegradable.
Click Accept to change your material to
Generate a Report.
Click on Generate Report and wait for Microsoft Word to launch.
You can key in your own comments and conclusion to justify your choice of material.
Save the Part file to save the material settings of the above SustainabilityXpress options.
If you’re thinking of purchasing drinking vessels for posterity’s sake, consider doing a comparison of
reusable cups with materials like: Glass
-Plastics: Melamine resin
-Other Non-metals: Ceramic porcelain
