The Himalayas-Karakoram-Hindukush system hosts water sources and feed the river system of Pakistan. This fluvial system provides for the water needs of the northern communities and nurtures the agrarian system further down south. According to the current climate change scenario and vulnerability of Pakistan to climate change it is projected that the country would be among water scarce nations by 2050 if suitable mitigation measures are not set in place for combating and adapting to climate change. Built environment contributes to 35% of resource extraction and usage, 40% of global energy use, consumes 12% of world’s drinkable water and produce 40% of the global Co2 emissions. Buildings are therefore a major driver of rising temperatures across the globe and can hence play an important role in reduction of Co2 emissions and energy consumption through efficient design and construction strategy. Led by Zahra Hussain, this research draws upon the extensive architectural pattern language mapping, sustainable buildings guidelines and mountain vernacular architecture and passive solar strategies for developing guidelines for architecture development in Pakistani Mountain Areas.
