Rainbow 2Ta Physics

• This is a compilation of the presentations my
  pupils made during a 2 week period. They examined
  in which areas the school could make changes
  which will have a positive influence on the
  enviroment.
• They made the presentations in dutch, the only
  thing I did was translating and combing them .

How expensive is an energy saving TL tube?

• How expensive is an energy saving TL tube? 8,90
  tot 9,20
• Whats the power of an energy saving TL tube? 10
  tot 26 Watt
• To replace all light bulbs with energy saving
  lighting the cost will be 10768,90 9576,40

How much do we save yearly with a energy
efficient lights?

• An energy efficient light wil save aprox.
  26107627976 Watt (efficient)
• 36107638736 Watt (normal)
• 38736 2797610760 Watt saving.
• Saves 10760 553800100053.8200 10760
  kWh0,50 5380,00 per year.

5
Summary

• We calculated that the school could save up to
  5400,00 a year, switching to the use of energy
  saving TL-tubes. The cost to replace all the
  lights with energy efficient TL-tubes, is about
  9600,00.
• We hope Mister Booij (our principal) will find
  some use for this information.

Light at school.

• Daniëlle, Kimberley, Joy, Simone.

7
What we have done?

• We checked every where in school to see if all
  light use was really necessary
• See what we could do to help people understand
  how to use energy more efficient
• And try to let people switch off the lights when
  they leave a classroom for more than 5 minutes.

8
How did we solve those problems?

• Investigate if there is enough light in a
  classroom or office when all lights are off or
  that half of the amount of lights will suffice.
• We could investigate if the switches in the rooms
  could be replaced by dual switches, so half of
  the lamps can be switched on. Energy efficient
  light are another option.

9
What is the use of all of this?

• Switching lights of when leaving, Replacing
  lights with the energy saving variant, or if
  possible using only half of the amount of lights
  or even none of them, is good for the enviroment
  and saves you money.

10
Why did we do this eventually!

• This presentation we made for the Rainbow
  project.
• And for Physics and Technical skills!

11
Saving on other lighting

• We will investigate how we can save energy on
  other (non-classrom) lighting in school

12
Our ideas

• More often switch of lights
• Energy saving bulbs
• Remove unnecessary lights
• Remove or dont use cosy lighting
• Try to use more natural light from outside
• PL - bulbs

13
PL-energy saving bulbs

• Those are energy saving bulbs, very usefull for
  saving energy

This is no energy saver (ordanary bulb)
PL bulb
14
Energy saving bulbs 2

• Those bulbs are more expensive than the old ones
  and thats the reason many people still use the
  ordinary bulbs, but they are misinformed. (energy
  saving bulbs earn themselves back in about a
  year)
• Its also proven that saverbulbs endure 5 times
  longer then the old bulbs when you keep both
  permanently switched on.

15
Reflection

• Use more reflecting materials to get more light

16
Energy use with the other lighting

• If we keep the lighting as it is, we use,
  somewhere in an office, for example a lightbulb
  of 60W , but we could also replace it with a
  PL-bulb of 12 W

• Cost
• The cost of a saver bulb is about 3,50. The bulb
  earns itself back within a year.

What did we do?

• We received the assignment to measure how much
  energy computers at school use. On Thursday the
  17th of January 2008 during our physics class we
  started the energy measurement at 14.05 on the
  computer in classroom 2.11 connected to an
  energymeter for 24 uur. On the 18th at 14.05 we
  red the used energy on the meter. Results follow.
  

20
Results
Time 24 hours
Consumption 3530 kWh
Costs 1.50
Above you see time, consumption and cost. The
highest measured poweruse was 205 W. At average
the computer used 147W. This is a meter like
the one we used. Energy-meter ?

tips

• Its redicilous and a sin to keep the computer
  turned on, while not using it. It saves a lot of
  money to switch it off, when youre not using it.
  Next to that, its not only good for your wallet,
  but also for the enviroment.

22
Last remark

• We hope this test shows everybody, who has seen
  this presentation, the urge to switch of your
  computer when youre not using it!!!!!!

Rainbow Project2007-2008

• Water

24
Watercost Zuid-Holland

• A family of 4 uses about 198,- per year on water
• On watertaxes you pay around 25,-
• Fixed charges are on average 52,-
• And 6 VAT counts up to 16,-
• This gives a total of 295,-

25
Ways to save on water use

• Taps with compression springs
• A watersaving shower
• A rainwater barrell in the garden. You can use
  this for watering the garden and cleaning the car
• No unnecessary long use of the shower
• Close the tap while cleaning your teeth

• Be more economical with your use of water, so we
  can use clean drinking water longer

Heating

• In and around Veurs Lyceum

Overview

• Gas consumption Veurs Lyceum
• Temperature Veurs lyceum
• Gasconsumption in a family home
• Difference in gas consumption at school and at
  home
• Result poll

31
Gasconsumption Veurs Lyceum

• Yearly gasconsumption over the last years
• 2000/2001 36735 m3
• 2001/2002 37180 m3
• 2002/2003 38541 m3
• 2003/2004 33135 m3
• 2005/2006 35660 m3

32
Temperature in Veurs Lyceum

• The average temperature in Veurs Lyceum is
• 20 C
• 68 F

33
Gas consumption in a family home

• In a badly insulated house the consumption of gas
  is about 2050 m3 for central heating, but you can
  reduce it to 700 m3 by insulating your house
  savinf 950,- yearly.

34
Difference in gasconsumption at school and at
home

• In a badly insulated house gas consumptioon is
  2050 m3 per year, at school it was in 2005/2006
  35660 m3 so a difference of 33610 m3.

35
24 hour measuring of the tempurature in classroom
2.11, the rise at the end was caused by someone
who took the thermosensor in his hand.
36
Poll

• We asked the teachers to fill in a poll. The
  questions were1 do you often turn the heating
  on?
• 2 do you ever look if the heating is on?
• 3 do you use the heating if necessary?
• 4 do you check the heating before opening the
  windows?
• 5 do you close the heating after a schoolday?

37
Poll result

• Mr Versleijen had the next answers
• 1 To be honest, its always on in winter
• 2 see question 1
• 3 see question 1
• 4 Yes I close the heater
• 5 no thats regulated by a computer
