This course introduces the basics of sustainability to interior design students. Environmental issues have become crucially important not only for the current but also for future generations. Inasmuch as interior design is mainly concerned with the occupation of space and the welfare of its users, students need to have a reasonable level of knowledge about sustainability and its desirable impacts on current and future human habitation. This course primarily explains the fundamentals of sustainability as regards its philosophy, theory, and set of principles to guide students from the first level of design through the construction and postconstruction phases. The course will demonstrate, through teacher-led case studies and student reports and projects, how guiding principles for sustainable interior design can result in better solutions for the current times and evolve into relevant future practices. Overall, this course will provide students with the knowledge and skills to design interior spaces that are visually and functionally appealing and sustainable
