This Master’s Thesis studies a dark-time landscape and lighting solutions in landscape and cityscape. Nowadays cities are more complex 24-hours systems. Life around the clock emphasizes an importance of designs to create safe and pleasant appearance of public spaces also in dark-time. The aim of this Thesis is to find the principles of modern lighting and develop the process between lighting design and landscape design. In this Thesis the four lighting perspectives are 24-hour city, user-centered lighting, light as visual factor in space and sustainability and resilience. The theory is based on landscape architecture. Spaces can be created by lighting as well as lighting infra at day and at dark time is part of the urban environment. Furthermore, rapidly developing technology enables resilience solutions and still follows the increasing need of new lighting solutions to be more user-centered. The survey among professionals was made to find out the current situation between landscape design and lighting design projects. The lighting criteria concept (LCC) was created from the current situation of lighting design. Dark-time landscape was analyzed in different scales. Lynch method of spatial analyzes was used in bigger scale to analyze areas’ landmarks, nodes and districts during the dark-time. In closer scale layers of lights analyze were used to find to the space and place feeling and to create more pleasant dark-time landscape. Two ongoing build environment projects, Jätkäsaari and Tripla in Helsinki were used as case areas. After Lynch method of spatial analyzes different kind of urban environments were taken to closer analyzing. These conceptual areas are a park, a hybrid space and a post-industrial site. In these conceptual urban enviroments were used as an example to create lighting as a service. The results emphasize the importance of dark-time experience of an urban landscape and a collaboration for achieving a new lighting solutions.
