The lighting industry has not only approached circularity within production of luminaires but also in contemporary time introduced a model of service that uses circular principles, lighting as a service (LaaS). Lighting as a service offers clients a leasing contract of luminaires including maintenance, upgrades and repairs. The concept is yet new and not very established to suit all fields. This thesis is focused on visual aesthetics and functional factors of lighting as a service in relation to clothing retail spaces. Lighting design has an important role for clothing stores' representation of products and customer’s experience which makes a complex relation between retail lighting design aims and lighting as a service to cohere. Methods used in this thesis includes site-visits to evaluate retail lighting qualities of various stores in Stockholm city, two case studies of earlier documented lighting as a service project that’s evaluated through two separate SWOT-analyzes. This to investigate principles of lighting as a service, visual aesthetics and functional factors and the possibility to practice the service in clothing retail spaces. The result is presented in written form and a 3d model made in the software program DIAlux evo.
