20.500.12556/RUL-146417 The necessity for multi-spectral simulations of the indoor non-visual luminous environment - a simplified annual approach Potrebna po večspektralnih simulacijah notranjega ne-vizualnega svetlobnega okolja - poenostavljen letni pristop The difference between the functioning of the human non-visual and photopic systems has elicited the need for complex in situ measurements or time-consuming multi-spectral simulations to accurately predict the non-visual luminous content of the indoor environment. As such methodologies are time-consuming, the aim of the present study was to determine whether such complex methodologies are needed. The issue was studied through simulations of four cardinally oriented identical offices located in Ljubljana, Slovenia. Each was studied using orange, grey and blue walls. Diurnal luminous conditions were studied under clear, hazy and overcast skies on December, March and June 21st. The non-visual content was evaluated using novel metrics, the Autonomy of Circadian Potential and Circadian Autonomy, which assess temporal circadian luminous content. Diurnal results were used to construct climate-based spectral months to evaluate the monthly non-visual potential of the studied offices. Furthermore, simulations addressed the question of whether the requirements of the non-visual system might contradict the visual comfort of indoor environments. The results show that compliance with non-visual requirements for indoor spaces with spectrally neutral surfaces or those in shades of blue could be assessed using photopic methodologies. However, this is not true for spaces characterised by orange and red materials. Potrditev drugačnega delovanja človeškega nevizualnega in fotopskega sistema je povzročila potrebo po zapletenih meritvah ali zapletenih večspektralnih simulacijah za natančno napovedovanje nevizualne svetlobne vsebine notranjega okolja. Ker so takšne metodologije zapletene in terjajo veliko časa, je bil cilj te študije ugotoviti, ali so tako zapletene metodologije sploh potrebne. To smo proučevali skozi študijo simulacij štirih kardinalno orientiranih pisarn. Vsako smo proučevali v različnih barvnih konfiguracijah sten (oranžne, sive ali modre sten). Dnevno svetlobo v prostoru smo simulirali v jasnih, meglenih in oblačnih pogojih 21. decembra, marca in junija. Nevizualna vsebina je bila ocenjena z uporabo novih metrik, avtonomije cirkadianega potenciala in cirkadiane avtonomije, ki ocenjujeta časovno cirkadiano svetlobno vsebino. Dnevni rezultati simulacij so bili uporabljeni za konstruiranje spektralnih mesecev, ki temeljijo na dejansk em podnebju, da bi ocenili mesečni nevizualni potencial proučevanih pisarn. Poleg tega so simulacije obravnavale vprašanje, ali so zahteve nevizualnega sistema morda v nasprotju z vizualnim udobjem notranjih okolij. Rezultati so pokazali, da je skladnost z nevizualnimi zahtevami za notranje prostore s spektralno nevtralnimi površinami ali površinami v modrih odtenkih mogoče oceniti z uporabo fotopskih metodologij. Vendar to ne velja za prostore, za katere so značilni oranžni in rdeči materiali. civil engineering daylighting non-visual daylighting buildings multi-spectral simulations photopic illuminance daylight glare probability gradbeništvo dnevna svetloba ne-vizualna dnevna svetloba stavbe večspektralne simulacije fotopska osvetlitev verjetnost pojava bleščanja true false true Angleški jezik Slovenski jezik Članek v reviji 2023-05-31 13:11:10 2023-05-31 13:11:14 2023-06-15 11:19:26 0000-00-00 00:00:00 2023 0 0 31 str.
