Rimliga förslag för energibesparing och konsumtion

Rimliga rekommendationer för minskad energiförbrukning (1):

Rekommendationer för energibesparande rationalisering:

  1. Angående energibesparing och vattenbesparing: luftkonditioneringens temperatur är densamma och rekommenderas 26. Slå inte på lamporna under dagen. Tänk bara på att tända lamporna under grumliga dagar. Var uppmärksam på antalet lampor. Vissa kontorsplatser har otaliga lampor, men de behöver det inte. Det rekommenderas att tända lamporna med jämna mellanrum. De tre ljusrören i en ljuslåda kan styras separat, och alla de första kan grupperas för kontroll, vilket kan spara mycket ström.
