CFD simulation and validation of self-cleaning on solar panel surfaces with superhydrophilic coating Tập 1 - Trang 1-15 - 2015
Jin Hu, Nicolas Bodard, Osmann Sari, Saffa Riffat
Solar panel conversion efficiency, typically in the twenty percent range, is reduced by dust, grime, pollen, and other particulates that accumulate on the solar panel. Cleaning dirty panels to maintain peak efficiency, which is especially hard to do for large solar-panel arrays. To develop a transparent, anti-soiling Nano-TiO2 coating to minimize the need for occasional cleaning is the purpose of ...... hiện toàn bộ
Development of Low-cost indigenous filtration system for urban sullage: assessment of reusability Tập 2 Số 1 - Trang 1-8 - 2016
Sikder, Tajuddin, Hossain, Zakir, Pingki, Priangka Bhattacharya, Biswas, Jussi Dayna, Rahman, Mostafizur, Hossain, Shakhaoat, Saito, Takeshi, Kurasaki, Masaaki
Treated sullage water could be the answer to urban water scarcity. In this study, urban sullage water was subjected to various tests to determine a number of physiochemical parameters, heavy metal content and coliform count. Obtained results were compared with the Dhaka Water and Sewerage Authority (DWASA) water samples. The sullage water was then treated using a proposed filtration system with in...... hiện toàn bộ
The need for UN climate change policy reformation Tập 2 Số 1 - Trang 1-13 - 2016
Bannaga, Sharaf Eldin Ibrahim
This paper endeavours to understand the climate change phenomenon and identify measures taken to contain it. It discusses global warming causes and consequences and assesses effectiveness of the United Nations (UN) polices following failure of the Kyoto Protocol to reduce greenhouse gas emissions. In pursuing this course of action, this paper utilizes data collected from East Africa region. Key is...... hiện toàn bộ
Comparison of building modelling assumptions and methods for urban scale heat demand forecasting Tập 3 - Trang 1-13 - 2017
Dirk Monien, Aneta Strzalka, Athanasios Koukofikis, Volker Coors, Ursula Eicker
Building energy evaluation tools available today are only able to effectively analyse individual buildings and usually either they require a high amount of input data or they are too imprecise in energy predictions at a city (district) scale because of too many assumptions made. In this paper, two tools based on 3D models are compared to see whether there is an approach that would probably be able...... hiện toàn bộ
Current progress in adsorption technologies for low-energy buildings Tập 1 - Trang 1-13 - 2015
Yu I. Aristov
More than half of the world’s population currently lives in cities. An essential constituent of future sustainable cities is energy efficient and ecologically sound buildings which ensure high levels of comfort and convenience without reducing the standards of living. At present, a significant part of primary fossil fuels is spent for heating/cooling of buildings, thus, greatly contributing to tot...... hiện toàn bộ
Urban sprawl and growth management – drivers, impacts and responses in selected European and US cities Tập 2 - Trang 1-13 - 2016
Christian Fertner, Gertrud Jørgensen, Thomas Alexander Sick Nielsen, Kjell Svenne Bernhard Nilsson
Urban growth management has become a common term to circumscribe strategies and tools to regulate urban land use in metropolitan areas. It is particularly used to counteract negative impacts of urban sprawl but also to frame future urban development. We discuss recent challenges of urban growth in 6 European and 2 US American city-regions. The paper compares the urban development focusing on a qua...... hiện toàn bộ
Planned energy-efficient retrofitting of a residential building in Italy Tập 1 - Trang 1-19 - 2015
Enzo Zanchini, Claudia Naldi, Stefano Lazzari, Gian Luca Morini
The planned energy-efficient retrofitting of a residential building in Bologna, North-Center Italy is presented. The building is a detached house with an unheated basement, three floors with 2 apartments each, and an unheated attic. The total heated floor area is 281.9 m2. The external wall is made of solid brick masonry and most windows are single glazed; no thermal insulation is present. Space h...... hiện toàn bộ
