Optimizing general indoor lighting of educational institutions and conforming to the appropriate standard

Radom je analizirano trenutno stanje rasvjete u objektu obrazovne ustanove. Dane su smjernice za optimizaciju i poboljšanje u skladu s odgovarajućom normom (HRN EN 12464-1) za rasvijetljenost unutarnjih radnih prostora. Analizirana je potrošnja električne energije postojeće rasvjete i ukazano je na ekonomsku isplativost potrebne investicije za objekt te energetsku učinkovitost projektirane rasvjete u odnosu na postojeću. Korištenjem Relux programa za modeliranje rasvjete odabrane su nove LED svjetiljke i provedeni potrebni izračuni. Posebna pozornost pri davanju prijedloga za poboljšanja bila je usmjerena na geografsku orijentaciju prostora te je rasvjeta optimizirana u skladu s prirodnim svjetlom.The paper analyzes the current state of lighting of the educational facility. In accordance with the appropriate standard (HRN EN 12464-1) for indoor lighting, the guidelines for optimization and improvement are provided. The paper analyzes electricity consumption of the existing lighting and indicates the economic profitability of the required investment in the facility and the energy efficiency of the designed lighting in relation to the existing one. Using the Relux lighting modeling program, new LED lightings were selected and the necessary calculations were performed. Special attention in giving suggestion for improvements was focused on the geographical orientation of the space and the lighting was optimized in accordance with the natural light
