This study only concerns with the valuation of open spaces; especially green parks and water bodies of different urban residential neighborhoods of Dhaka city in Economic terms. To analyze the impact of open space attributes on real price of residential properties, an empirical analysis is carried out by employing Hedonic Price Method (HPM). Together with a set of structural, location and socio-economic variables use to explain residential property prices; the study focuses on three amenity or environmental variables which include the existence of views of park, the distance from the housing unit to the nearest open space, and the size of that open space. The regression analysis results from the first stage hedonic estimation reveal that homebuyers are willing to pay only for scenic views and living in the closest proximity to open spaces especially green parks. In contrast results for the size of the nearest open space for houses do not show a significant relationship on nearby property values. This estimated valuation of open spaces and their amenity benefits will be useful for decision making in urban design, land use planning and green space preservation.","PeriodicalId":404901,"journal":{"name":"2015 3rd International Conference on Green Energy and Technology (ICGET)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124477388","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}

To keep the system running a lot of fossil fuels need to be burned as a result the volume of greenhouse gases into the air increases. This study introduces a new technology which is emerging as viable alternatives of conventional vapor-compression systems and is known as adsorption cooling system. This system is environment friendly since it uses natural refrigerants and it is driven by low temperature waste heat or solar energy that is why it can solve the existing challenge of global warming and energy crisis.","PeriodicalId":404901,"journal":{"name":"2015 3rd International Conference on Green Energy and Technology (ICGET)","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124242461","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}

Energy is crucial input in the process of economic, social and industrial development. Energy plays a vital role in our daily life. But the conventional source of energy to produce electricity is decreasing day by day significantly. In this regards non-conventional or renewable energy resources such as bio-energy, Solar, Wind, Ocean and Geothermal are taking this challenge. A large proportion of the world's population lives in remote rural areas and far away from grid. The installation and distribution costs are considerably higher for remote areas. Moreover, there is greater transmission line losses and poor supply reliability. There is growing interest in harnessing renewable energy sources since they are available in abundance, pollution free and inexhaustible. Not only that, The combining of technologies means Hybrid technology provides interesting opportunities to overcome certain technical limitations and to mitigate fuel price increases, deliver operating cost reductions, and offer higher service quality than traditional single-source generation systems. A hybrid system is a dynamic system that exhibits both continuous and discrete dynamic behavior a system that can both flow and jump.","PeriodicalId":404901,"journal":{"name":"2015 3rd International Conference on Green Energy and Technology (ICGET)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124474966","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}

Despite a lot of attempts by the Bangladesh Government, due to increasing population & rapid industrial growth, this problem seems to be augmenting day by day. Energy preservation is the result of financial capital increase of the country and also increases the environmental values. Being a developing country, Bangladesh lacks the utilization of renewable energy sources, so almost majority of the power generation techniques are based on Fossil Fuel, Gas and Coal, which is created air and water pollution, also negative impact on global calamity. So, to solve the power crisis, alternative means are needed to be taken account of. If power consumption can be reduced somehow, then with the present generation capacity, it would be possible to generate power in coherence with the demand of the consumers. In this paper, we have discussed about how Solid State Lighting (SSL) like Light Emitting Diode (LED) can reduce the daily power consumption in Bangladesh. SSL offers many benefits such as long life, energy saving, better quality light and so on, only one drawback is initially high cost which is not accountable for long terms use. By utilizing the features of SSL the power consumption in Bangladesh can be reduced significantly. We have represented the features of solid state lighting compared to other means of lighting sources. We have shown LEDs prospective contribution in reducing the power consumption with necessary calculations and statistics.","PeriodicalId":404901,"journal":{"name":"2015 3rd International Conference on Green Energy and Technology (ICGET)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126191790","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 proposed ANN based controller has the ability to estimate wind speed by tracking the maximum power point (MPP) and the optimal rotor speed with very low error compared to the conventional MPPT methods. The algorithm is based on two series neural networks, one for wind speed estimation and the other for tracking maximum power point. The method demonstrates remarkable performance in estimating wind speed under rapidly changing wind conditions. It can also predict MPP accurately avoiding undesired oscillations around maximum power point. The algorithm does not require any mechanical sensor for wind speed measurement. Nonlinear time domain simulations have been carried out to validate the effectiveness of the proposed controllers in terms of wind speed estimation and MPPT under different operating conditions. Simulation results confirm the effectiveness of the MPPT controller in tracking the maximum power point under rapidly changing wind conditions.","PeriodicalId":404901,"journal":{"name":"2015 3rd International Conference on Green Energy and Technology (ICGET)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117058155","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}

Eventually renewable energy is a better choice. There is an increasing trend of using solar cell in the industry as well as to household appliance because solar energy is expected to play a prominent role in future smart grid as a distributed renewable source. For optimal and large scale integration of solar energy several modeling software and computer program is used. In this paper a stand-alone solar system of 2kW with battery backup, being located in Dhaka, Bangladesh is designed by using a MATLAB program named SolarMAT and two popular software PVsyst v5.06 and HOMER. Both PVsyst and HOMER are versatile and renowned software in the field of solar system design and modeling. PVsyt and HOMER have to be purchased, unlike SolarMAT, which is a free tool and it is developed in MATLAB environment which can also accurately design a solar system but not that much like the other two. To check the acceptance of these software, the final result will be compared with the practical data. Another widespread photovoltaic solar system configuration known as grid tie system can also be designed by both of these tools.","PeriodicalId":404901,"journal":{"name":"2015 3rd International Conference on Green Energy and Technology (ICGET)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134106915","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}
