Integrating photovoltaic systems into the urban landscape is fundamental to the wide scale acceptance of the technology. It is also one of the major factors currently limiting its popularity, coupled with high costs, and the lack of adequate storage methods. Contributing to the lack of architectural integration are shortcomings in design tools and an overall lack of forward thinking proposals suggesting how society can begin implementing solar power on a large scale. Research conducted by the International Energy Agency 'Task 41: Solar Energy and Architecture' has identified the need for more developed toolsets to help designers quantify solar exposure and shading coefficients during the conceptual design phase. Although software to calculate incident surface radiation is available, it is largely detached from the traditional design process and workflow. What is required to improve the architectural integration of photovoltaic systems is a new design methodology. A method that must be both inherently flexible and quantifiable, so that designers can validate and modify designs quickly and efficiently. In a process where innovative digital tools combined with the intuition of the designer expand the creative possibilities of intelligent solar architecture. The aim of the project is to develop a new design methodology by combining parametric and environmental analysis tools, providing quantitative performance indicators in order to assist architects at the early design stage. Using case studies, the project will demonstrate how this methodology is applicable to a wide array of project typologies within an urban context. In addition to demonstrating the applicability of the system, the case studies would also illustrate the potential for photvoltaic installations to alter the landscape of the city and facilitate a fresh dialogue between public space and renewable energy generation.

The main objective of this research is analysed and compared the performance of two solar power plants to identify the possible operational problems in the tropical region. The grid connected PV power plants considered in the present study, Ten Merina and Senergy, were installed in the region of Thies (Senegal). Solar power plants have the same installed capacity 29.491 MWp. A period of one operation year of the solar power plants is considered, starting from January 2018 to December 2018. The performance parameters developed by the International Energy Agency (IEA) are used to analyse the performances of solar power plants. The results show that the plane of array irradiance at the sites is identical with an annual average of 6.2 kWh/m2/d. The annual average performance ratio and final yield of solar power plants are respectively 74.3 %; 4.61 kWh/kWp to Ten Merina and 75.9 %; 4.66 kWh/kWp to Senergy. These results are compared to other solar power plants installed in different locations around the world.

This paper aims to analyze the photovoltaic electricity energy expansion and recent data about the behavior of the CO2 emissions in Brazil and other selected countries. Data were collected from different bases as International Energy Agency (Agência Internacional de Energia), Ministry of Energy and Mines (Ministério de Minas e Energia), Research Electric Company as well as other papers in the field. Kaya Identity was applied as basis in order to evaluate the CO2 emissions. As a result, it could be seen a clear domain of Germany and Italy in the photovoltaic generation sector, with high investments in the development and dissemination of that technology. Brazil presented an energetic matrix of low carbon but with a tendency to increase emissions per capita throughout the years. The effect of decoupling between the greenhouse gas emissions and the large-scale economic development was checked. It was realized that that phenomenon tends to intensify it since renewable energy technologies get higher levels of use.

New Ideas

The rapid changes and crises in the field of energy during the 1970s and 1980s have forced us to examine the use of energy more critically and to look for new ideas. Seasonal aquifer thermal energy storage (T < 100°C) on a large scale is one of the grey areas which have not yet been extensively explored. However, projects are currently underway in a dozen countries. In Finland there have been three demonstration projects from 1974 to 1987. International co-operation under the auspices of the International Energy Agency, Annex VI, ‘Environmental and Chemical Aspects of Thermal Energy Storage in Aquifers and Research and Development of Water Treatment Methods' started in 1987. The research being undertaken in 8 countries includes several elements fundamental to hydrochemistry and biochemistry.

Space Case

The use of the moving image in public space extends the techniques of cinema — namely superimposition, montage, and apparatus/dispositif — threatening, on one end of the spectrum, to dehistoricise and distract, and promising to provide new narrative and associative possibilities on the other. These techniques also serve as helpful tools for analysis and practice drawn from cinema studies that can be applied to examples of the moving image in public space. Case studies and creative works are presented in order to examine and illustrate the ways that public projections extend the effect of superimposition through the rehistoricisation of space, expand the diegetic boundaries of the moving image through spatial montage, and enact new possibilities for the cinematic apparatus and dispositif through scale and interaction in order to reframe and democratise historical narratives and scripts of urban behaviour.

<p>As human society nears the middle of the second decade of the 21st century, the cultivation of fossil fuels for energy shows little sign of large scale abatement. The need for large scale, worldwide transitions to more renewable energy is increasingly being emphasised by organisations such as the International Energy Agency. Some countries are leading the way and innovating in energy sources that are much more efficient, create industry, and bring many system benefits- like solar photovoltaic systems (PV).  Despite having insolation similar to, or greater than, many of those countries seeing vast uptake of solar PV, New Zealand is falling behind. New Zealand has policies in place that emphasise new renewable energy technology uptake and innovation; however these are not occurring with solar PV on a large scale. These contradictions underpin the examination in this thesis of the solar PV innovation system.   Using a Technological Innovation System (TIS) framework, this thesis examines the innovation system for solar PV in New Zealand. It identifies the achieved functionality in eight areas (Entrepreneurship, Knowledge Development, Networks, Guidance, Market, Legitimacy, and International Influences), and assesses the overall system’s functioning to identify system weaknesses.  To build a more complete picture of the innovation system, this thesis also examines the political environment that influences the sustainable transition to more solar PV. The key stakeholders, political influences, priorities, preferences, and political dialogue are assessed using a quantitative questionnaire. The results of this political analysis contribute to a robust conclusion on the state and functioning of the solar PV TIS in New Zealand.</p>

Near Future

In this article, the future in photovoltaic energy productivity (PVE) is evaluated using climate variables simulated aerosol clearness index and solar irradiance, it is a model for the performance of photovoltaic systems. The analysis indicates that the aerosol emission reductions in the near future result in an increase in global warming with a significant response of the solar surface radiation and associated PVE productivity. Changes in radiation surface and productivity of solar PVE are related to overall reduction in aerosol effects on the circulation and large scale associated with cloud coverage pattern, rather than local atmospheric effects on optical properties. PVE evaluation is then discussed in the context of the current situation and the PV market highlighting the effects on productivity induced by industrial and public policies, while technological development are comparable to the effects related to the weather. The results presented encourage the improvement and further use of climate models in the assessment of future availability for renewable energy.

Foundation Stone

ABSTRACT:The infrastructures of devotion and religious worship in Ireland changed dramatically during the course of the nineteenth century. This article examines the foundation stone ceremonies that marked the beginning of several large-scale building Roman Catholic church building projects between 1850 and 1900, and in particular considers the extent to which these highly visible and ceremonial events prefigured the more permanent occupation of public space by the new buildings. These foundation stone ceremonies were complex events that reflected contemporary political issues such as land rights as much as they engaged with the spiritual concerns of the Roman Catholic congregations in Ireland during this period.
