Environmental Adaptations for Achieving Sustainable Regeneration: A Conceptual Design Analysis on Built Heritage Fujian Tulous.

Environmental adaptation is essential for maintaining a building's indoor environmental quality and performance. This paper is focused on heritage regeneration research of the sustainable paradigm of Fujian Tulous in China. These earthen dwellings were built hundreds of years ago and were proven to be conventional green buildings today. However, few researchers have clarified or specified regenerative approaches for Tulous in response to realistic demands and sustainable concerns. Our study surveyed 10 non-world-heritage Tulou cases in Nanjing County, Fujian Province, China. Environmental adaptation in the Tulou archetype was analysed through an intensive review and field investigation to explain how they interacted with local climatic conditions. This article analysed the green effects of building components on five passive design strategies—thermal comfort, solar shading, natural lighting, ventilation, and waterproofing—and then proposed conceptual design strategies based on three aspects: reshaping building envelopes, reorganising spatial layouts, and using innovative construction materials and techniques. The conclusions indicated that, to realise the sustainable generation goals of non-world-heritage Tulous, environmental, socioeconomic, and cultural issues have to be considered, among which environmental adaptation should be a primary approach.
