To reduce material consumption needed in production as well as avoiding thousands of tons of contaminations produced by spent materials in the battery industry, recycling was taken into consideration. In this study silica was recycled from spent lead-acid battery separators by the pyrolysis process. silica along with high-density polyethylene (HDPE), can be used as supporting material for fabricating form-stable phase change materials (FSPCM). FSPCMs are of great ability to be used as thermal energy storage (TES) in different parts of a building e. g. wallboards to reduce energy consumption. In this line, an eutectic mixture of lauric acid, palmitic acid and paraffin with the melting point... 

Optimal use of available resources for construction projects depends on proper decision-making on how to spend resources. Optimization of resource consumption should be done taking into account project revenue. In this regard, investors need a suitable mechanism to predict the selling price of the construction project and the resulting profit. Therefore, investors and stakeholders need a suitable model with the help of which they can make decisions such as choosing materials to guarantee the desired profit from the sale. This research will provide a framework for constructing models for estimating the price of residential units by considering some features of the building and some economic... 

This study proposes a probabilistic approach to prioritize a collection of buildings in a region for seismic retrofit based on regional risk analysis. Risk in this context is the exceedance probability of total economic and social losses, which include both direct and indirect consequences resulting from building damage. The prioritization criterion is determined by the benefit-to-cost ratio of retrofit, where the benefit is measured by the reduction of seismic risk achieved through retrofitting. Hence, the buildings are analyzed both in their current state and after retrofit to compute the risk measure, i.e., the mean total loss. Buildings that yield the highest reduction of the risk...
