A complete hybrid system including a photovoltaic cell, a wind turbine, and battery is modeled to determine the best approach for sizing the system to meet the electrical energy needs of a residential building. In evaluating system performance, the city of Tehran is used as a case study. Matlab...

This paper investigates the breakdown of primary energy use and greenhouse gas (GHG) emissions of two common types of exterior walls in the U.K.: insulated concrete form (ICF) and cavity walls. A comprehensive assessment was conducted to evaluate the environmental performance of each exterior...

Rice forage systems can increase the land use efficiency in paddy fields, improve the self-sufficient feed ratio, and provide environmental benefits for agro-ecosystems. This system often decreased economic benefits compared with those through imported commercial forage feed, particularly in...

Life Cycle Assessment (LCA) has been increasingly used to improve the environmental performance of food systems and simplification of LCA appears to be a vital question, especially for Small- and Medium-sized Enterprises (SMEs). Following a literature review on simplified LCA tools and their...

With rapid development since the 1970s, China is entering a period of social transformation, which not only creates favorable conditions for sustainable development but also presents new challenges. The transitional period in China is a stage in which two types of social transformation coexist,...
