In the world, 55% of the population lives in cities and is expected to increase to 68% by 2050. Cities are identified by their stunning skyscrapers which turn out to consume 75% of total power consumption. It is most important to emphasize energy efficiency and nonpolluting building materials used for construction. These days buildings have different types of designs to satisfy the specific requirements of its purpose and people who live and work in them. As time goes, with growing technology, the building constructions need to be designed and function with real-time natural environments with land, water and solar energy  [ 1 ] . Thus sustainable practices and materials for building design and function are necessary for a sustainable future. According to the world green building council, a building in its architecture, construction or function, eliminates negative impacts and generates positive impacts on our environment is referred as a green building. Green buildings are mostly d...

A group of researchers and their team (Zhao et al .) from various Universities ( Tsinghua University, China, Southeast University, China, Columbia University, New York, Imperial College London, and The Ohio State University, USA) have surveyed a review on biomass-based chemical loops, its good, bad, and future aspects. Zhao et al ., have discussed the biomass, which is considered to be one of a promising renewable energy resource owing to its high moisture content, low energy density, and complex ash components. Biomass is a major energy source, it is considered to be a carbon-neutral renewable and abundant energy resource. The use of carbon in biomass for energy production, which was obtained from atmospheric CO 2 , is considered to be a carbon-neutral fuel. When this biomass is combined with carbon capture technology, then the overall energy conversion progress will be in negative in terms of net CO 2 emission, which is to be termed as BECCS (bioenergy with carbon capture and stora...
