Vernacular solutions for small houses in Ha Tinh City towards sustainable and adaptation to climate change

Geographically located on the central coastal plain of Vietnam, with low, flat topography, Ha Tinh City has an urban architecture which interwoven closely with very characteristic rural areas. In 2017-2021, we conducted a research project on building a system of green architecture criteria and proposed architectural design solutions for sustainable small-scale housing in Ha Tinh City in the context of climate change. The research project has conducted surveys, interviews and measurements of climate data at 195 representative houses in 4 typical urban areas of the city. Based on very detailed survey results, combined with the traditional vernacular experience gained from local experts and residents, we have gradually analyzed and assessed the effects of climate change on houses and human activities, from which to build a set of criteria to guide people to build or renovate their homes in the direction of green vernacular architecture which is more sustainable and better adapt to climate change in Ha Tinh.
