1. ECO-AUDITS
Students from Primary 5 and 6 participated in Eco-Audits last May.
They calculated the annual usage of water, electricity and gas, and its cost.
WATER CONSUMPTION DATA IN THE YEARS 2009 - 2010 – 2011 May):
Number of students eco-auditors: 25 (5th Primary)
Number of users: 279
Use of water: standard (WC, cleaning, drinking fountain, watering the garden, dinning-room service
cleaning …)
Consumption of water: 92,80 l. x person x day average – It includes building period
Service terminals: 97
Taps: 60 timer taps and faucets
5 monocomanders
1 hand-lever
Stopcocks hidden for students
no roulette tap, no foot-lever
Saving devices: Aerators – None, except in the kitchen bassin
Water stopcock – Hidden for students
Flow reducers - None
Flanges - None
WC: 31, all of them with a pushing button (double button)

2. Saving devices: Toilet tank emptying stop button - None
Water saving bags- None
Double button – All
Water stopcock – Hidden for students
Use of information stickers - None
Water leaks: None (it's a new building, operating since September 2010)
Purposes: reducing the water consumption at 5 l/pn/day
By: Using a flange/ring in timer taps
Using aerators in hand washing monocomander taps to reduce water flow at 4 – 5 l/minute
Information stickers next to all the double buttons
Using water bags inside the toilet tanks
Reusing cleaning water for toilets
Using rain-water for gardening/cleaning
Using xero-gardening concept to optimize our water use.
ENERGY CONSUMPTION DATA IN A YEAR (ADDING OF LAST 12
MONTHS)– audit in 2011 April/May):
Number of students eco-auditors: 24 (6th Primary)
Number of users: 279
Buildings : 1
Floors: 3
Useful surface in m2: 3730,16
Use of energy: standard (lighting, heating, machines and devices)
Consumption of energy: 122.191.901 kWh – It includes building period
Cost amount: 179910 € - Cost x person: 64,1935 €
Energy sources: Power, Natural gas, Renewable (solar thermal and photovoltaic)
Power: 74901 kWh/person Total cost: 12025 € Surface rate- 20,0798 kWh/m2
Gas: 437,695 kWh/person Total cost: 5887 € Surface rate: 32.7377 kWh/m2
Use of energy: standard (central heating and water heating for the dining room & showers)
Solar devices: No data about production was available
Thermal pannels: 6 units, on top of the building - Useful area: 13,62 m2 - Use: heating
Photovoltaic devices: existing, but hidden to students. - Use : power production
The audit helped students and teachers to detect the strong and weak points of our school towards
this issue and draw up proposals of improvement.

3. STRONG POINTS
Building/ classroom
1 Our school is well-equipped, with computers and other digital tools
2 It's a new building
Light and electricity
1 There are fluorescent bulbs which consume less energy
2 It has solar photovoltaic panels
Heating and hot water
1 Pupils and teachers have a high awareness of energy saving
2 It has solar thermal energy.
WEAK POINTS
Building/ classroom
1 The building is not oriented to take advantage of solar energy
2 The building is not well insulated to save energy
3 Difficulties in opening or closing the blinds
4 Difficulties in opening some windows
Light and electricity
1 There's no natural light
2 There are a lot of electrical appliances
3 LED lights are sometimes left on
4 It's possible to reduce some more energy
Heating and hot water
1 It's not possible to regulate the temperature in each room ( There's no a zoned temperature control
for heating)
2 Windows don't allow good ventilation.
It's not possible to insulate the temperature of the classroom.
3 The orientation of the building don't let take adventage of natural light
4 The temperature is too high in some school areas and low in others
SOME PROPOSALS OF IMPROVEMENT
Building/Classroom
1 New buildings are much more energy efficient, we should take adventage of this fact
2 We'll open the blinds in winter and we'll close them in summer
3 We'll open windows in summer and we'll close them in winter

4. Light and electricity
1Lights and Leds should be switch off whenever they are not needed
2 It's necessary to change and adjust the lamps of the gym
3 We have to exploit the natural light resource
Heating and hot water
1 A zone control system is necessary to regulate the temperature of the heating, room-by-room
2 We have to take more advantage of the energy from solar thermal panels
THE PURPOSE OF THIS ACTIVITY IS TO RAISE ENVIROMENTAL AWARDNESS IN
ORDER TO HAVE A GREENER SCHOOL.
