Green building has attracted widespread attention in recent years. Increasing building projects in Iran has had significant environmental impacts and green building implementation is an appropriate approach to reduce the environmental risks. Green building projects facing with risks unwittingly which, reduce their efficiency. Therefore, identifying and ranking the risks can play a significant role in the success of green building projects. Due to the few studies in this area in Iran, this study aims to provides a new comprehensive framework of all the criteria and risks of green building projects. For this purpose, the first step aims to identify and screen the risks from the viewpoint of experts in green building projects and introducing the risk assessment criteria. After that, the next step is to apply the SWARA method to obtain the weight of the criteria. Finally, Ranking of the risks of green building projects has been done using the COPRAS method. This is the first attempt to solve a green building project using a hybrid of SWARA and COPRAS through a case study (Amol). The results show that risks of: the low quality of materials and equipment, the stakeholder resistance to approve the green ideas and lack of realistic goals are very important. The proposed framework can help stakeholders of green building projects in developing countries to manage project risks more efficiently.

Value engineering is one of the tools to create and improvement value while reduces unnecessary costs and keeps the original function, leads to increased efficiency. Today this technique used to reduce the cost in industries that are facing high costs such as the electricity industry. The evidence and expert’s opinion implying that many factors causing costs in the industry is related to the supply chain the low efficiency in the supply chain, resulting in increased costs. So to increase performance and reduce costs, the research was conducted aimed to identify and prioritize solutions reduce costs in the supply chain for cables and accessories combined cycle power plant Sirjan (Gol Gohar), who has a major role in the country's electricity supply. The final solutions for cost reduction after holding several meetings with experts of the project value engineering team were identified. Then these solutions were evaluated with criteria extracted of the research literature and opinions of experts of the project value engineering team were moderated and finalized. The final criteria and each of the sub-criteria were weighted by SWARA. Then final weight was calculated for each of the sub-criteria. In order to prioritize final solutions we used ARAS-G. After prioritizing solutions, solution the twelfth (reducing the time of order up to purchase and deliver through the reform procedures purchase), as the best solution was identified to reduce costs and thus increase performance supply chain target
