Earth Hour savings

Earth_Hour__result_Last Friday Team Green ran an Earth hour during period six in which all unnecessary electronic devices were (supposedly) turned off. This is part of the attempt to hold an earth hour on the last Friday of every month to conserve energy and cut down the schools power use. During this hour the average electricity consumption fell from 4.8 KW to 2.38 KW.

More Earth hours will be held on the last Friday of every month for the rest of the school year in order to raise awareness on the issue of energy use.

Earth Hour results

On Friday 27th March at 2.15pm when the bell announced the end of lunchtime, a group of students went around school and reminded everyone to switch off lights and other electric appliances.

We have been recording the kW consumption with an electricity monitor for a week before and after the event in one block of the college. The blue line is the average consumption during the week, around 3.88 kW.

The green line is the kW consumption during the Earth Hour, averaging 1.50kW.

2015 Earth Hour monitoring

We have calculated that it saves about $20.

We propose to organise Earth Hour once a month, on the last Friday of each month.

The next Earth Hour will be on the 29th May.

Earth Hour at MAC

Earth Hour is a worldwide lights-off event that will happen on Saturday March 28 between 8:30 and 9.30pm.

Here at MAC, we’ll turn off all unnecessary electricity during period 6 on Friday 27th March. We monitored previous Earth Hours at MAC and found that the electricity consumption halved during the period, hence saving about $20.

Participate and be part of a global movement!

Innovation project


MAC_innovation_challenge_prezi_image

Our latest exciting goal is to embed sustainability into the curriculum and the college culture. Our Principal has agreed to establish the MAC Kaitiaki innovation Challenge aiming to raise awareness and empower students to be guardians of our resources by the end of term 1 2014.

We are working on:

  • An audit of the resources used
  • How to communicate our project to students and staff and enthuse them
  • A repository of curriculum resources
  • Best actions to save money to build our seed fund
  • Funding applications

End of term successes

Earth Hour

Friday Period 6 Earth Hour has been awesomely supported, with most lights out before we went around the college to do it. We had talked about Earth Hour in Assembly and showed everyone the 3 minutes clip and we put posters up throughout the school, so it worked well.

The records above are done with a Cent-a-meter http://www.centameter.co.nz/placed in one of the college buildings, and do not reflect the whole school electricity consumption.

Tree planting

We received 19 trees from Te Kakano for last year paper recycling, as part as the Paper4Trees programme and planted them today in the college field, with the help of Andrew Penniket and Don. No photo sorry, our hands were dirty!

Save Energy campaign

Today, we’ve put up 10 posters in the college to remind students and teachers to save energy.

Our energy bill is huge and wasting energy is crazy, because it uses up resources that are in limited supply AND it adds CO2 and other pollutions in the atmosphere, which contribute to climate change.

By just being mindful, we can make a difference!
