  1. 1. Energy
  2. 2. Lighting <ul><li>Lights use electricity. In Scoil Mhuire we try to </li></ul><ul><li>ensure that this energy is not used in a wasteful </li></ul><ul><li>manner. </li></ul><ul><li>All lights in our school operate on a sensor system </li></ul><ul><li>and switch off if no movement is detected . </li></ul><ul><li>The lights adjust to outside daylight . </li></ul><ul><li>All lights in toilets have motion timed sensors. </li></ul><ul><li>The perimeter security lights are 8W and are </li></ul><ul><li>controlled by a photocell. </li></ul><ul><li>We encourage that lights are switched off when </li></ul><ul><li>leaving the room and if they are not necessary </li></ul><ul><li>when in the room. </li></ul><ul><li>A member of the Energy Squad in each classroom </li></ul><ul><li>is responsible for switching off classroom lights </li></ul><ul><li>when they are not necessary. </li></ul><ul><li>Signs with our NRG Moose are placed on the light </li></ul><ul><li>switches in shared areas to remind us to switch </li></ul><ul><li>them off when finished. </li></ul><ul><li>Our Code is “C.B.S., hear our shout. Don’t </li></ul><ul><li>forget the lights go out!” </li></ul>Light sensor on a classroom ceiling
  3. 3. Electrical Appliances <ul><li>Electrical appliances use electricity even </li></ul><ul><li>when in stand-by. We try to prevent this power </li></ul><ul><li>being wasted. This saves our school money and </li></ul><ul><li>helps the environment. </li></ul><ul><li>Each class has an Energy Squad member who </li></ul><ul><li>is responsible for ensuring electrical appliances </li></ul><ul><li>are switched off when they are not in use and at </li></ul><ul><li>the end of the day. </li></ul><ul><li>We have a “Switch it off. Plug it out” policy to </li></ul><ul><li>eliminate the “red-eye”. </li></ul><ul><li>During the day, we switch off the computer </li></ul><ul><li>monitors when the computers are not in use. </li></ul><ul><li>Our photocopier has an energy saver mode. </li></ul><ul><li>We record our meter readings and try to beat our </li></ul><ul><li>previous results. </li></ul><ul><li>Our Code is “You switch it off. You plug it out. </li></ul><ul><li>That’s what it’s all about.” </li></ul>Our meter gives us separate day and night readings
  4. 4. Heating <ul><li>Originally our school heating used oil. Oil is a </li></ul><ul><li>non-renewable source of energy. We now have </li></ul><ul><li>a biomass system. This system uses wood </li></ul><ul><li>pellets, a renewable source of energy. </li></ul><ul><li>The G.P. area, used by the public at night, has </li></ul><ul><li>its own programme which can be set </li></ul><ul><li>automatically. This means that just the area in </li></ul><ul><li>use, and not the whole school, is heated. </li></ul><ul><li>All classrooms and corridors have pre-set </li></ul><ul><li>thermostats. The heating controls adapt </li></ul><ul><li>automatically to outside temperatures. </li></ul><ul><li>All outer doors have slow closing hinges. Some </li></ul><ul><li>have p.v.c. porches. We keep outer doors shut </li></ul><ul><li>to prevent heat loss. </li></ul><ul><li>Our old windows have been replaced by double- </li></ul><ul><li>glazing and fit tightly. We do not put classroom </li></ul><ul><li>furniture in front of radiators as this would block </li></ul><ul><li>the heat. </li></ul><ul><li>If we are leaving our classroom to go to lunch or </li></ul><ul><li>the gym, we close the classroom door. If </li></ul><ul><li>windows are left open to ventilate the classroom, </li></ul><ul><li>radiators are switched off. </li></ul><ul><li>All windows and doors are closed at home-time </li></ul><ul><li>and the blinds drawn during cold weather. </li></ul><ul><li>Our Code is “Keep the school sweet. Save our </li></ul><ul><li>heat.” NRG Moose reminds us to shut doors in </li></ul><ul><li>shared areas. </li></ul>Our biomass boiler Wood pellets for the biomass heating system
  5. 5. W.E.E.E. <ul><li>The Green Schools Committee took part in </li></ul><ul><li>an initiative organised by W.E.E.E. </li></ul><ul><li>A representative came to our school for a </li></ul><ul><li>day and gave a workshop to all classes in </li></ul><ul><li>the school. </li></ul><ul><li>After the talk, we had a W.E.E.E. </li></ul><ul><li>Recycling Day and collected two bins full </li></ul><ul><li>of electrical appliances. We had hoped to </li></ul><ul><li>fill just one! </li></ul><ul><li>We received a reconditioned P.C. as a </li></ul><ul><li>reward for our efforts. </li></ul>Filling the bins with unwanted electrical appliances
  6. 6. S.E.I. <ul><li>We are a designated flagship project for </li></ul><ul><li>biomass heating systems. </li></ul><ul><li>We have been given a plaque by S.E.I. </li></ul><ul><li>for this. </li></ul><ul><li>The plaque is on the wall beside the front </li></ul><ul><li>door. </li></ul><ul><li>Go to </li></ul><ul><li>to read more about our biomass heating </li></ul><ul><li>system. </li></ul>Plaque from SEI
  7. 7. Energy Rating <ul><li>Our school underwent an energy efficiency </li></ul><ul><li>assessment. </li></ul><ul><li>We received an energy rating of B3. </li></ul><ul><li>This was a fantastic result as our school is </li></ul><ul><li>over 50 years old. </li></ul>
  8. 8. Low Energy Day <ul><li>Low Energy Day is held every year in our school. The </li></ul><ul><li>aim is to make us more aware that we take instant </li></ul><ul><li>energy for granted and to help us realise the amount </li></ul><ul><li>of energy used by our school on a daily basis. </li></ul><ul><li>On Low Energy Day, we switch off lights (and hope </li></ul><ul><li>for a bright day). </li></ul><ul><li>We switch off all electrical appliances (except those </li></ul><ul><li>used by the office). </li></ul><ul><li>Some teachers bring flasks of tea!! No kettles </li></ul><ul><li>allowed…. </li></ul><ul><li>The photocopier gets a well-deserved break. </li></ul><ul><li>It’s back to the past. No interactive whiteboard or </li></ul><ul><li>computers for the day! School as it was in our </li></ul><ul><li>parents’ time. </li></ul><ul><li>At rest, we use the same amount of energy as a 20W </li></ul><ul><li>lightbulb! Imagine what we use when we’re active. </li></ul>Some of the reminder signs for Low Energy Day
  9. 9. NRG Moose <ul><li>Meet our NRG Moose. </li></ul><ul><li>During Green Week, the Green Schools </li></ul><ul><li>Committee organised some competitions. </li></ul><ul><li>One was to design an energy mascot for </li></ul><ul><li>our school. </li></ul><ul><li>We had lots of creative and imaginative </li></ul><ul><li>entries. This is the winning entry and was </li></ul><ul><li>designed by a sixth class student. </li></ul><ul><li>You’ll find NRG Moose on signs around </li></ul><ul><li>our school. </li></ul><ul><li>He reminds us to shut doors, to switch off </li></ul><ul><li>lights and to plug out appliances. </li></ul>Our mascot, NRG Moose
