igreen: green skills for the future workforce

The igreen program is a joint initiative of Steplight and Dusseldorp Skills Forum. Last year saw the implementation of the first round of igreen programs (in NSW, Victoria and Tasmania).

Watch the video below for a brief summary of the program.

What is igreen?

Quotes from the igreen video:

It’s a program for those kids that are going to be looking for a job when they complete school… They actually have to go out into their community: introduce themselves to their community and do house assessments. It gives them a realisation that they can go further with it, to gain further accreditation.

- Maggie MacFie (Central Coast Youth Connections)

The igreen program starts with students and young people assessing exactly how they impact on the environment and by having young people then showing this concern and going out into the community. It’s spreading the message. It’s really a powerful message for people to take in – that they, in their own homes make a significant difference to the overall environmental resources in this country and across the world.

We wanted to have the igreen program at Gorokan High School for a number of reasons but I suppose a primary one is the environmental factor.

- Les Clark (Principal, Gorokan High School)

I think it’s the sort of program that will help me in the future because I’ve got the credentials and know what needs to be done and I’ve got the certificates to show it. It might get me a job in home sustainability.

- Student

The Training

For the training that we did, we had three different [types] of training: some in the classroom where we worked out of a booklet [...] And then we learnt how to use the software on the internet [...] And we also went out on day trips to practice using the information.

- Student

When students are taking up the issues of the environment and they’re going out and meeting members of the community and going into their homes to help those people assess their energy use, it’s a significant thing for students, and it really does build up their confidence.

- Les Clark

The Benefits

I’d tell other people to do this because it’s fun and it’s a real hands-on course where you get to go out and learn stuff on the job.

- Student

I think a lot of schools would benefit from taking on this program. It has the capacity to engage students and it is a significant program in terms of our environmental responsibilities for the future, for future students and their families.

- Les Clark

I’d recommend this program because it’s really educational and it can help in future life as well.

- Student

It puts these young people in quite a unique position where they actually will be providing advice and giving information to people that are much older than themselves. So they have to come across as credible. [These are] really good skills to learn for the future work force.

Green skills are important. They are the skills of the future.

Watts Clever? Using a plug-in mains power meter

Watts clever plug-in power meterPlug-in power meters allow you to measure the electricity consumption of appliances around your home or workplace. A range of energy saving options can often be identified, and if nothing else, the devices will help you understand which appliances are using the most energy. The usage guide shown below is for this plug-in mains power meter available from Steplight.

Measuring Standby Loads

These are the steps to measure the standby power consumption of an appliance:

  1. Plug the appliance into the power meter.standby power foxtel box and tv remote control
  2. Turn the appliance back on to ‘stand by’ (eg, so the remote can be used on a television).
  3. Press ‘FUNC’ on the power meter twice to display the power consumption in Watts.
  4. This is how much power the appliance is using in standby mode.

So how much can be saved by turning all these appliances off at the wall?

  1. Measure the standby power (in Watts) of an individual or group of appliances.
  2. To work out the cost, find how much you pay per kWh on your electricity bill (often around $0.25/kWh), and multiply this by the hours in standby per day (an example of 20 hours per day is shown below).
  3. To calculate the approximate total savings (the power meter can do a similar calculation to this automatically if you have already entered your electricity tariff):

Measuring Appliance Electricity Consumption

There are two ways to measure appliance consumption. If you know how often an appliance is used then measure the Watts of the appliance and multiply this by the number of hours:

power meter calculationFor some appliances, power usage changes over time, so consumption cannot be calculated using the above method. This is the case for a refrigerator that turns on and off throughout the day, or a washing machine where the power used will depend on what cycle is running. You can use the power meter to work out the usage over time, and the cost, using the following steps:

  1. Plug the appliance into the power meter
  2. Set the cost of electricity on the power meter to what you pay (see manual)
  3. Leave the appliance plugged into the power meter for the desired measurement time (24 hours, one washing machine load, etc.)
  4. Come back after the specified time and press the ‘FUNC’ button until you come to ‘kWh’ for consumption or ‘Total Price’ for cost.

Understanding temperature to save energy

Energy Efficiency

Temperature can be a rough indicator of appliance energy efficiency. Most electrical appliances produce ‘waste heat’ when switched on. This is because all the components inside them are not 100% efficient and the wasted energy is typically converted to heat. As such, inefficient appliances usually produce more waste heat than efficient ones (think of hot halogen down-lights, poorly insulated ovens, and so on). Do you have wasteful appliances which could be used less or replaced with energy efficient alternatives?

Thermal Comfort

Radiant temperature, in particular, is an important aspect of thermal comfort. You can use a non-contact thermometer to find what parts of your building are letting in too much heat in summer or sucking it all out in winter. Measure the surface temperature of a window and compare it to an internal wall. Can action be taken to better manage heat loss or heat gain through the window?

Air Conditioners

As a rule of thumb, a one degree adjustment can save around 10% off your heating and/or cooling costs. Most people find a temperature of 24-26 degrees to be pleasant in summer and 18-20 degrees suitable in winter. If you use an air conditioner or ducted heating, these are good guidelines to follow. Setting an air conditioner lower in summer typically does not make it work any faster. It will just use more electricity because the compressor will stay on for longer.

Refrigerators

Fridges and freezers often remain on their over-spec factory settings. To measure the fridge or freezer temperature, place a thermometer inside and leave it there for 30 minutes. Four degrees is recommended for your fridge and as ‘warm’ as -12 degrees is suitable for the freezer. Adjust the settings on your unit as appropriate. A freezer set at -12 will safely store foods for relatively ‘short’ periods (2-3 months). The factory settings of around -18 degrees can store food for longer periods, but this is unnecessary in most cases.

Green jobs or greener jobs?

In today’s Sydney Morning Herald, Ross Gittins poses the questions: what is a green job? and, why are we aiming to create them anyway? He makes the point that simply putting the focus on creating ‘green jobs’ could do little to meet the goal of a low-carbon economy.

He goes on to outline the conundrums surrounding defining what a green job might be:

If, for instance, a job maintaining a wind turbine is a green job, what about a job in the business that makes the turbines?

And if it’s green to manufacture steel turbines, what about the jobs of the people who mine the iron ore and coking coal needed to make the steel? But if it’s not green to be a miner, would it be better for us to import all the turbines we need so the sin of being non-green was on someone else’s head?

We tend to agree – there probably won’t ever be a suitable description of a green job. Here at Steplight our focus is on delivering quality educational outcomes to those we work with, so we’re not too caught up in defining ‘green jobs.’ The outcome we are aiming for is more informed people who are empowered and equipped to take action in reducing their ecological footprint. This can take many shapes: from helping a business complete a review of their energy consumption, delivering sustainability training to a community, or supporting the delivery of home sustainability assessment programs.

Two of our programs, which are a joint initiative of Steplight and Dusseldorp Skills Forum, go one step further by including practical experience and employment opportunities for young people. The Y Green program is a home sustainability project where young people are trained and then employed to conduct sustainability assessments in their local community (see video below). The igreen program, on the other hand, involves high school students completing accredited training and then going on to complete a number of home sustainability assessments in their local community as practical experience.

In reality, very few of the participants in these programs will actually end up being full-time home sustainability assessors. But that’s not the point. By completing a course in sustainability and then applying this knowledge in their community, participants in these programs gain valuable experience not just in sustainability, but also customer service, workplace safety, and so on. Whatever field they go on to work in we hope they’ll be making more informed decisions about the broader environmental impact of their every-day actions.

So maybe it’s time we put the focus on greener jobs and creating valuable green skills. Then everyone’s job can be a ‘green job.’

igreen train-the-trainer in Home Sustainability Assessment underway

igreen train-the-trainer at Steplight, home sustainability assessment course19 teachers from four states have commenced the igreen train-the-trainer at Steplight this morning. The training event, made possible by Dusseldorp Skills Forum and Integral Energy is an opportunity for secondary school teachers to complete a nationally recognised Course in Home Sustainability Assessment (21854VIC). This is the course that forms part of the igreen program.

igreen is a secondary school program which assists households in becoming more sustainable and creates opportunities for the development of green skills in young people. It involves students completing a nationally recognised training program and then going on to complete a number of home sustainability assessments in their local community. The assessments involve providing advice and information on household energy and water efficiency.

Upon completion of the train-the-trainer course this week, participants will be qualified to teach this course (under auspicing arrangements) to secondary school students in Years 9, 10 and 11.
