This thesis is based upon the architectural competition brief of the Ilulissat Icefjord Centre in Greenland and includes a design proposal for the brief together with the design process. A light analysis tool has also been developed in parallel through this process, and has been used actively in the design process. The main focuses of this thesis is daylight seen from a human perspective and indoor thermal conditions located in an extreme climate. The design proposal reflects the main focus and the analysis of the site.
