Office lighting appraisal, performance, and well-being: a linked mechanisms map

Most would agree that a high-quality lighting installation provides good task visibility and contributes to the attractiveness of the space. In two experiments in a simulated office space, temporary office personnel worked under one of six lighting conditions for a day. Combined results from two statistical approaches show that people who perceived their office lighting as being of higher quality rated the space as more attractive, reported more pleasant mood, and showed greater well-being at the end of the day. Direct-indirect lighting and personal control were favoured. Lighting conditions that improved visibility also improved task performance.Il fait presque l'unanimit\ue9 qu'une installation d'\ue9clairage de qualit\ue9 procure une bonne visibilit\ue9 de la t\ue2che ou de l'ouvrage tout en contribuant \ue0 l'esth\ue9tique de l'espace de travail. Dans le cadre de deux exp\ue9riences se d\ue9roulant dans un local \ue0 bureaux de simulation, des employ\ue9s de bureau temporaires ont travaill\ue9 pendant un (1) jour dans l'une de six (6) conditions d'\ue9clairage diff\ue9rentes. Selon les r\ue9sultats combin\ue9s de deux (2) approches statistiques, les employ\ue9s qui percevaient l'\ue9clairage de leur bureau comme \ue9tant de meilleure qualit\ue9 jugeaient que l'espace en question \ue9tait plus esth\ue9tique, faisaient \ue9tat d'une ambiance plus agr\ue9able et \ue9prouvaient une plus grande sensation de bien-\ueatre \ue0 la fin de leur journ\ue9e de travail. On dit pr\ue9f\ue9rer les appareils \ue0 \ue9clairage direct/indirect, ainsi que les commandes individuelles. Les conditions d'\ue9clairage qui am\ue9lioraient la visibilit\ue9 favorisaient du m\ueame coup l'ex\ue9cution des t\ue2ches.Also published in Eletricidade Moderna, v. 36, no. 410, May 2008, pp. 106, 108, 110, 112, 114.Peer reviewed: YesNRC publication: Ye
