Abstract:

The intention is to develop a better understanding of what message in the form of atmosphere are people receiving from the light solutions of open public spaces and what characteristics contribute to build this perception. The method consists of two main stages. For the first stage a methodology to critically observe lighting solutions is developed. The methodology is based on the combination of past studies from Anders Liljefors and Carolina Hiller. The second stage comprehends an analysis of the lighting solutions of three case studies in Stockholm province area. Using a questionnaire, general public is asked to observe the lighting in specific areas of each case study to do a further categorization into atmospheres.

The premise is that by understanding the characteristics, that contribute to the perception of specific atmospheres, the lighting designer can conceive a project efficiently: by strengthening the relation between the project’s intention and the final user’s perception.

Sustainable Lighting Strategies for Nytorps Gärde, A Case Study

Abstract:

This paper focuses on exterior lighting strategies for Nytorps Gärde, a suburban green area in Stockholm, serving as a case study. The research methodology includes a comprehensive literature review, a survey, quantitative measurements, and expert interviews. The study highlights the importance of creating sustainable urban spaces and addresses the inherent challenge of balancing the needs of both people and the ecosystem. A site specific design intervention is proposed for the space, presenting a lighting solution for a footpath that simultaneously minimises feelings of threat whilst simultaneously having a minimal light pollution footprint Furthermore, the discussion emphasises the significance of implementing lighting controls and explores the influence of light quality and topography on perceived safety. The primary objective of this thesis is to provide strategic guidance for lighting design in the proposed development, with a particular emphasis on incorporating the perspectives of women and girls in shaping the nocturnal environment.
