ENVIRONMENTAL AUDIT OF OUR SCHOOL LORENZO DA PONTE

• ELECTRIC ENERGY• HEATING• TRANSPORT • PAPER• WATER• WASTE

• Comenius project “Let’s know, let’s love, let’s protect our environment”

We split into four different groups:

1. Transports2. Heating3. Electricity 4. Paper consumption

We have prepared a questionnaire and

chosen six classes, the sample classes .

THESE ARE OUR SAMPLE

CLASSES110 students

•THE QUESTIONNAIRE:• 1. Which means of transport do you use to come to school?• and with what means of transport do you return? • outward: □by car □ by bus □ walking □by bike• come back : □by car □by bus □walking □by bike

• 2. How far is your home from school?

• 3. If you come by car, are there any students who• come with you? and the return?

Series1

• Students at School: 374• Using car: 47% (175 students)

• Using bus: 24% ( 90 students)

• Average distance covered: 7 km (return)

For a total of :

371000 km in a school year (200 days)

Summary

If you come by car, are there any students who come with you?

31% of the students share the car with a mate

How far is your home from school? Of the 52 children who come to school by car 70% live at

a distance equal to or less than 2 km from the school

< 2 km > 2 kmdistance from school distance from school

THE HEATING We interviewed Luigi, our caretaker and we found out that the fuel with which we heat

the school is methane

We requested data to the Municipality of Vittorio Veneto to know what was our methane consumption

Alberto, Andrea, Eros, Federico e Yaro

1 How many would be willing to lowerof a degree the temperature?

2 How many people believe in class it is too hot?

3 How many students report that they keep the windows flapped for many hours?

• Our school consumes 28.750 cubic meters of methane per year.

CONSUMPTION OF PAPER IN OUR SCHOOL

1898 Kg of paper In a whole year we consumed :

OF WHICH:

PAPER A4

1300 Kg per year

PAPER A3

140 kg per year

A ream weighs 2 Kg A ream weighs 4 Kg

FOOLSCAP

320 Kg

PAPER FOR THE HYGIENE

238 kg

A ream weighs 2 Kg A roll weighs 1,2 kg A roll weighs 60 g

Interviewing Mrs. Loretta we verified that in one day about two reams of paper are used, equivalent to 1000 sheets, without considering the secretariat and the presidency.

ELECTRICITY’S CONSUMPTIONS

1- In 2014 our school consumed 53537 kwh (date reported by Vittorio Veneto’s town hall)

We checked and we found that in every class there are 8 neon tubes ( each neon has 58 watt)

if in a classroom the light was turned on for 5 hours, it would consume : in 1 day = 2,32 kwh ( 58 watt x 8 neon tubes x 5 : 1000= 2 ,32 kwh) 1 month = 58 kwh ( 2,32kwh x 25 = 58 kwh)

1 classroom in a year = 464 kwh

5- In our school there are 380 neon tubes for a consumption of 110 kwh in a day (in five hours but the school closes at 18:00)

IN A SCHOOL YEAR: 110 x 200 =22000 Kwh

How can we reduce the CO2 emissions?

We can reduce the emission of CO2 with simple behaviours

The 122 students, who live at less than 2 km from the school, could come to school

walking or by bike

Car pooling is the best choice

You will save 237 gr CO2/per kilometer for each person

We found out that in our institute we only use non-recycled paper, for which production there is a bigger emission of CO2 than for the recycled paper.

Decreasing the heater’s temperature of 1 ° Celsius our consumption would

decrease of 7%,which is above 2012 cubic meters of

methane in a school year

We saw that in the aisles the lights are always on, therefore we have to find a

solution to save energy .

We can do a lot to reduce the emission of co2.

1)If we switched off half the lights that are in corridors we would save 4060 KWh per year.

2)If we switched off the light in the classrooms during the break we would save 23,2 KWh for each classroom.

Our results

TOTAL: 166 725 kg CO2

Putting in practice 3^ A hints

TOTAL: 119 049 kg CO2

CO2 saved

47 675 kg CO2

Everybody can!!!!!!

THE END
