The MG consists of a photovoltaic system (PVS) and a lead-acid battery bank (BB). The optimisation utilised a twenty-four hour forecast of building energy consumption and the corresponding electrical prices from the NPG. A piecemeal decision algorithm (PDA) and a particle swarm optimisation (PSO) algorithm were used to generate a charge/discharge rates schedule for the BB. The building energy consumption model was developed using empirical data and employee work schedules. Electricity prices were predicted using a real time pricing (RTP) model based on data from the single electricity market operator (SEM-O)[1]. The PVS and BB were modelled based on specifications from manufacturers, and weather data from the Cork Institute of Technology (CIT). The simulation results demonstrate that the building operating costs can be reduced by up to 23 % per day for a single charge/discharge rates schedule, or by up to 30 % per day for a multiple charge/discharge rates schedule.","PeriodicalId":259036,"journal":{"name":"2015 World Congress on Sustainable Technologies (WCST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129354673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the South African green building market has not reached enough maturity and gained strong support from the industry stakeholders yet. Major barriers to green building development are particularly related to the gap of available data about the financial implications of green buildings in the local market, which creates uncertainty for the investments in building \"green\". This study aims to provide a contribution towards overcoming these barriers, by investigating the property developers' perception on green building and its cost implications in the South African province of KwaZulu-Natal, and by providing a preliminary cost-benefit assessment of an accredited green building in Durban. Findings demonstrated that developers have started to recognize the financial benefits of green buildings and perceived that in the near future they will become the norm. The preliminary cost-benefit analysis showed short payback period and profitability for the investment in green measures. The results of this study may constitute a first step into a more comprehensive understanding of the economic implications of green building in a young green building market such as the South African one, encouraging its development and growth.","PeriodicalId":259036,"journal":{"name":"2015 World Congress on Sustainable Technologies (WCST)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121220209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ever more stringent environmental regulations also contribute to pressurize the iron and steel industry to strengthen further its research activities fostering an optimal management and exploitation of resources. Thus important research efforts are spent in order to find the best way to recover wastes and wastewater also involving the implementation of retrofit actions and major plant modifications allowing also the reduction of primary raw material consumption and of waste disposal. In order to achieve such ambitious objective, which implies both environmental benefits and cost savings, process integration is a powerful tool. The assessment of the viability of process integration solution necessarily include a final experimental stage to be performed at plant level, which can be expensive or unsafe. To this aim process simulation can be a useful alternative to accomplish preliminary feasibility studies allowing a deep analysis of all the aspect of a particular technology or retrofit actions, which also allows testing conditions that are very difficult to replicate within practical experiments. Different levels of detail can be achieved and a comprehensive analysis can be carried out. The present paper provides an overview of the simulation techniques exploited during the project entitled \"Efficient Use of Resources in Steel Plants through Process Integration\" to the aim of optimizing the use of resources in an Italian integrated steelmaking plant. In particular, different case studies are proposed and the obtained meaningful and practical results are presented and discussed.","PeriodicalId":259036,"journal":{"name":"2015 World Congress on Sustainable Technologies (WCST)","volume":"217 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115923239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The blast furnace gas washing process, in steelworks, is a major water consumer and a significant contributor to water pollution. Environmental emissions and energy efficiency legislation have become increasingly stringent, and have made it essential to manage water and reduce emissions. Thus any reduction in blowdown flowrate from the process would significantly improve the quality of the discharged water. This in turn could unlock the potential for water reuse opportunities. This second part of the paper discusses the field trial results and the resulting simulation of different regeneration-reuse scenarios within the research undertaken at a Tata Steel blast furnace plant (UK) in collaboration with Process Integration Limited (UK). The research results have led to the identification of a range of benefits in terms of water conservation, material efficiency, energy efficiency, environmental compliance, and treatment costs.","PeriodicalId":259036,"journal":{"name":"2015 World Congress on Sustainable Technologies (WCST)","volume":"52-54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116772872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
