Adaptive reuse of Hanasaari power plant B

Adaptive reuse of buildings has generally accompanied the development of human civilization, from the Roman Empire plundering of constructions in conquered territories to the occupation of pagan architecture during the Christian period, from the pursuit of the beauty of antiquity in the Renaissance to the study and discussion about the authenticity and value of architectural heritage in the 19th century by the scholars from various disciplines including art history, archaeology and philosophy.etc. The pioneers have developed the architectural heritage conservation into a complete, sophisticated and precise discipline. Today, when reusing the emerging architectural heritage, technical and social sustainability need to be fully considered as well in addition to the research and preservation of the values. In this thesis, the subject of reuse is the Hanasaari Power Plant B designed by architect Timo Penttilä located in the Kalasatama area on the eastern side of Helsinki. Because of the development of the HELEN Company’s transition to clean energy, the large-scale plant that generates electricity and heat by fuel is about to be shut down in 2024. For the power plant building, the architect used the excellent composition of masses, precise modular design, elegant facade rhythm, and material selection to subvert the image of traditional industrial architecture and make the power plant an icon of Finnish modernist architecture in the 1970s. Therefore, even if the age of the power plant is not sufficient to be a legacy, its architectural value is worth protecting. Meanwhile, Kalasatama area is planning to be a new modern urban area in the future, Hanasaari Power Plant B should act as an anchor to connect the past to display the history and memory of the area. For this industrial buildings group in the city, the thinking of this thesis bases on the protection of the values of the Hanasaari Power Plant B, which reflect in its appearance, the enormous interior space and structure and the industrial atmosphere in the architectural group. Through urban design, the introduction of new functions and the reorganization of space and structure, the isolated area of the city would be integrated into the developing city fabric. Moreover, this industrial heritage would be involved in society and peoples’ life
