Mae'r siart hwn yn dangos dadansoddiad o bryd mae ysgolion yn defnyddio nwy. Mae diwrnod ysgol ar agor pan fydd yr ysgol ar agor i ddisgyblion a staff. Diwrnod ysgol ar gau yw pan fydd yr ysgol ar gau i ddisgyblion a staff dros nos.
Mae'r rhan fwyaf o ysgolion yn wag am tua 85% o'r flwyddyn; rhwng 5:00pm a 7:30am ar ddiwrnodau ysgol, ar benwythnosau ac yn ystod gwyliau. Ffocws ar leihau'r defnydd o nwy y tu allan i oriau; mae troi systemau gwresogi a dŵr poeth i ffwrdd y tu allan i oriau yn rhoi ffordd gost-effeithiol i ysgolion leihau eu defnydd cyffredinol.
Dylai ysgolion anelu at leihau eu defnydd o nwy y tu allan i oriau o dan 35% o'u defnydd blynyddol.
