Energetický management pro energetické manažery ve školství a sociálních službách

Publikace je určena správcům budov a energetických hospodářství v sociálních službách, školách a dalších budovách v majetku obcí. Stručným a jednoduchým způsobem poskytuje návod, jak sledovat a vyhodnocovat spotřeby energií a návody, jak zamezit zbytečným spotřebám a tedy i zbytečným výdajům na energie, kde a jak hledat provozní úspory.
