Sustainability helps humanity meet their needs without affecting the resources of future generations. Recently, many ideas had come together in the call for sustainable development. The building sector, directly or indirectly, has been causing a considerable portion of the annual environmental deterioration. But now, it can take up its obligation to contribute to sustainable development by finding more environmental methods for construction. Sustainable building could be defined as the building that, in its design, construction, or operation, reduces negative environmental impacts, protects occupant health, and uses wisely natural resources. The design of sustainable buildings should thus begin with the selection and use of eco-friendly materials with better features than traditional building materials. Building and fire resistance materials were traditionally selected through functional, technical, and financial requirements. Nowadays, the selection of construction and fire resistance materials that have minimum environmental burdens is preferable. Changing the properties of materials without affecting their chemical composition can now be easily achieved utilizing nanotechnology. Not only materials, sustainable energy sources also matter. Not-In-Kind (NIK) cooling technology concept was introduced to avoid long-term damage to the environment. The NIK cooling technologies proved its success not only in savings the environment but in saving energy and achieving financial profits as well. The choice of refrigerants and their environmental impacts have encouraged a hugh portion of researchers.
