Wind Energy In The Built Environment

This book describes the wind resources in the built environment that can be converted into energy by a wind turbine. It especially deals with the integration of a wind turbine and a building in such a way that the building concentrates the available wind energy for the wind turbine. The three different ways to concentrate wind power are examined: wind turbines on the roof or at the sides of a building; wind turbines between two airfoil shaped buildings; wind turbines in ducts through buildings.

Energy security, rising energy prices (oil, gas, electricity), 'peak oil', environmental pollution, nuclear energy, climate change and sustainable living are hot topics across the globe. Meanwhile, abundant and perpetual wind resources offer opportunities, via recent technological developments, to provide part of the solution to address these key issues. The rapid growth of large-scale wind farm installations has now led to the generation of clean electricity for tens of millions of homes around the world. However, despite the potential to reduce the losses and costs associated with transmission and to use local wind acceleration techniques to improve energy yields, the potential for urban wind energy has yet to be realised. Although there is increasing public interest, the uptake of urban wind energy in suitable areas has been slow. This is in part due to a lack of understanding of key issues such as: available wind resources; technology integration; planning processes (include assessment of environmental impacts and public safety due to close proximity to people and property); energy consumption in buildings versus energy production from turbines; economics (including grants, subsidies, maintenance); and the effect of complex urban windscapes on performance. Urban Wind Energy attempts to illuminate these areas, addressing common concerns highlighting pitfalls, offering real world examples and providing a framework to assess viability in energy, environmental and economic terms. It is a comprehensive guide to urban wind energy for architects, engineers, planners, developers, investors, policy-makers, manufacturers and students as well as community organisations and home-owners interested in generating their own clean electricity.

"Twenty-seven architecture students developed strategies to integrate wind turbines in their design projects of a [hypothetical] maritime museum in Erie, PA ... The main objective was to observe how emerging architects approach this design task of turbine integration while creating architectural entities for a meaningful environment. The following text summarizes the design process, categorizes different design approaches, and evaluates the design outcomes concentrating on their level of building integration and efficiency"--P. 3-4.

This book addresses the main challenges faced today in implementing the Nearly Zero Energy Buildings (nZEB) concept. The book starts with a chapter that addresses problems related to the energy demand and renewable energy sources available in the built environment, along with the restrictions and opportunities in developing sustainable, efficient and affordable solutions, also gaining aesthetic and architectural acceptance. Advanced solutions to cover the energy needs by using various renewable-based energy mixes are presented in two chapters. These two chapters discuss the problem of conversion efficiency at the level of components and systems, aiming at giving value to the variable renewable energy sources, in producing thermal and electric energy. The concept is discussed further in a chapter on advanced solutions for water re-use and recycling wastes as second raw materials. The need for new strategies and implementation tools, for education and training is addressed in the final chapter as part of the nZEB concept, towards sustainable communities. The sub-chapters of the book were openly presented during the 4th Edition of the Conference for Sustainable Energy, held 6-8 November, 2014 and organized by the R&D Centre Renewable Energy Systems and Recycling at the Transilvania University of Brasov, Romania. This event was developed under the patronage of the International Federation for the Promotion of Mechanism and Machine Science (IFToMM), through the Technical Committee Sustainable Energy Systems.

This book presents numerical and experimental research in the field of wind energy exploitation in urban environments. It comprises a selection of the best papers from the international colloquium “Research and Innovation on Wind Energy Exploitation in Urban Environment” (TUrbWind), held in Riva del Garda, Italy in June 2017. The book includes contributions from different research fields in urban wind resources, wind energy conversion systems, and urban integration, mainly focusing on the following topics: · concepts for urban and open landscape micro wind turbines, · integration of micro wind turbines in existing structures, · built-environment and high-turbulence sites’ impacts on urban wind turbines, · measuring and modeling wind resource in built environments, · rotor performance and wake features of micro wind turbines. It is a valuable resource for researchers and practitioners interested in the integration of wind energy systems and turbines in urban areas.

This book focuses on solar energy conversion systems that can be implemented in the built environment, at building or at community level. The quest for developing a sustainable built environment asks for specific solutions to provide clean energy based on renewable sources, and solar energy is considered one of the cleanest available energy on Earth. The specific issues raised by the implementation location are discussed, including the climatic profile distorted by the buildings, the available surface on the buildings for implementation, etc. This book also discusses the seasonal and diurnal variability of the solar energy resource in parallel with the variability of the electrical and thermal energy demand in the built environment (particularly focusing on the residential buildings). Solutions are proposed to match these variabilities, including the development of energy mixes with other renewables (e.g. geothermal or biomass, for thermal energy production). Specific solutions, including case studies of systems implemented on buildings all over the world, are presented and analyzed for electrical and for thermal energy production and the main differences in the systems design are outlined. The conversion efficiency (thus the output) and the main causes of energy losses are considered in both cases. The architectural constraints are additionally considered and novel solar energy convertors with different shapes and colors are presented and discussed. The durability of the solar energy conversion systems is analyzed considering the specific issues that occur when these systems are implemented in the built environment; based on practical examples, general conclusions are formulated and specific aspects are discussed in relation to experimental results and literature data. With renewables implemented in the built environment likely to expand in the near future, this book represents welcome and timely material for all professionals and researchers that are aiming to provide efficient and feasible solutions for the sustainable built environment.

The generation of electricity by wind energy has the potential to reduce environmental impacts caused by the use of fossil fuels. Although the use of wind energy to generate electricity is increasing rapidly in the United States, government guidance to help communities and developers evaluate and plan proposed wind-energy projects is lacking. Environmental Impacts of Wind-Energy Projects offers an analysis of the environmental benefits and drawbacks of wind energy, along with an evaluation guide to aid decision-making about projects. It includes a case study of the mid-Atlantic highlands, a mountainous area that spans parts of West Virginia, Virginia, Maryland, and Pennsylvania. This book will inform policy makers at the federal, state, and local levels.

The book presents a state-of-the-art in environmental aerodynamics and the structural design of wind energy support structures, particularly from a modern computational perspective. Examples include real-life applications dealing with pollutant dispersion in the building environment, pedestrian-level winds, comfort levels, relevant legislation and remedial measures. Design methodologies for wind energy structures include reliability assessment and code frameworks.
