The Council on Tall Buildings and Urban Habitat has produced four Technical Guides to date, since the series launched in late 2012. Each of these guides is the product of a CTBUH Working Group—committees formed specifically to address focused topical subjects in the industry. The intention of each guide is the same—to provide working knowledge to the typical building owner or professional who wants a better understanding of available options for improving tall buildings, and what affects their design. The object of the series is to provide a tool-kit for the creation of better-performing tall buildings, and to spread the understanding of the considerations that need to be made in designing tall. This technical guide offers an extensive overview of the use of vertical vegetation in high-rise buildings, an indepth analysis of green walls, definitions and typology, including standards, policies and incentives. It features comprehensive case studies, along with architectural theories of the public and private benefits of green walls. The book delves into architect-design considerations and limitations, the effects of green walls on energy efficiencies and includes recommendations and future research.
The notion that humanity may be too late to alter climate change could potentially lead to fear and therefore the advocacy of implementing radical strategies and/or hastening the execution of certain measures to the extreme. There is evidence that extensive and intensive implementation of some climate change solutions can significantly alter the environment and ecosystems in unintended ways. For example, the microclimate of a field in the proximity and downstream of a closely packed array of wind turbines can be noticeably altered by the modified lower atmospheric fluxes caused by the turbines, which can then negatively affect crop yields. Additionally, some studies have found that large-scale solar fields can result in the modulation of atmospheric circulation, leading to changes in regional precipitation. The Costs of Climate Change Mitigation Innovations: A Pragmatic Outlook provides a forum for discussion on the long-term consequences of various climate strategies. It promotes our striving toward minimizing the potential negative impact of new interventions by performing objective, holistic analyses. The bottom line is that we do not want today's solutions to become tomorrow’s problems.
Eco-Towers introduces readers to groundbreaking designs, most progressive projects, and innovative ways of thinking about a new generation of green skyscrapers that could provide solutions to crises the world faces today including climate change, depleting resources, deteriorating ecology, population increase, decreasing food supply, urban heat island effect, pollution, deforestation, and more. The book suggests that the eco-tower culminates the cultural and technological evolutions of the 21st century by building and improving on the experiences of earlier designs of skyscrapers and philosophies particularly green, sustainable, and ecological. It argues that the true green skyscraper is the one that engages successfully with its larger urban context by establishing symbiotic relationships with the social, economic, and environmental aspects. Since tall buildings are becoming larger and taller, serving greater number of people, and exerting higher demand on the environment and existing infrastructure, any improvements in their design and construction will significantly enhance urban conditions. The book elucidates how green skyscrapers better serve tenants, mitigate environmental impacts, and improve integration with the city infrastructure. It explains how skyscrapers’ long life cycle offers the greatest justifications for recycling precious resources, and makes it a worthwhile to employ green features in constructing new skyscrapers and retrofitting existing ones. Subsequently, the book explores new designs that are employing cutting-edge green technologies at a grand scale including water-saving technologies, solar panels, helical wind turbines, sunlight-sensing LED lights, rainwater catchment systems, graywater and blackwater recycling systems, seawater-powered air conditioning, and the like. In the future, new building materials and smart technologies will continue to offer innovative design approaches to sustainable tall buildings with new aesthetics, referred to as “eco-iconic” skyscrapers.
This is the proceedings of the Eighth International Conference on Design Computing and Cognition (DCC’18) held at the Polytecnico di Milano in Italy. This volume presents both advances in theory and applications and demonstrates the depth and breadth of design computing and design cognition. Design thinking, the label given to the acts of designing, has become a paradigmatic view that has transcended the discipline of design and is now widely used in business and elsewhere. As a consequence there is an increasing interest in design research. This volume contains papers that represent the state-of-the-art research and developments in design computing and design cognition. This book is of particular interest to researchers, developers and users of advanced computation in design and those who need to gain a better understanding of designing that can be obtained through empirical studies.
Tall buildings are not the only solution for achieving sustainability through increased density in cities but, given the scale of current population shifts, the vertical city is increasingly being seen as the most viable solution for many urban centers. However, the full implications of concentrating more people on smaller plots of land by building vertically - whether for work, residential or leisure functions - needs to be better researched and understood. It is generally accepted that we need to reduce the energy equation � in both operating and embodied terms � of every component and system in the building as an essential element in making it more sustainable. Mechanical HVAC systems (Heating, Ventilation and Air-Conditioning) in tall office buildings typically account for 30-40 percent of overall building energy consumption. The increased efficiency (or possibly even elimination) of these mechanical systems � through the provision of natural ventilation � could thus be argued to be the most important single step we could make in making tall buildings more sustainable. This guide sets out recommendations for every phase of the planning, construction and operation of natural ventilation systems in these buildings, including local climatic factors that need to be taken into account, how to plan for seasonal variations in weather, and the risks in adopting different implementation strategies. All of the recommendations are based on analysis of the research findings from richly-illustrated international case studies. Tried and tested solutions to real-life problems make this an essential guide for anyone working on the design and operation of tall buildings anywhere in the world. This is the first technical guide from the Council on Tall Buildings and Urban Habitat�s Tall Buildings and Sustainability Working Group looking in depth at a key element in the creation of tall buildings with a much-reduced environme
Purpose of the Book In today's world, where sustainability and energy efficiency have become paramount, the significance of retrofitting and renovation has never been more relevant.

By the end of this book, you will be well-prepared to embark on your own renovation journey, whether it involves minor updates or a complete overhaul. Scope of the Book Retrofit and renovation are often used interchangeably, yet they serve different purposes and involve distinct processes. This book clearly distinguishes between the two, while also showing how they can be complementary in creating modern, efficient buildings that respect their historical roots. Retrofit typically involves the addition of new technology or features to an existing building, with a strong focus on improving energy efficiency, safety, and resilience to environmental challenges. Examples include upgrading insulation, installing solar panels, or reinforcing structures against seismic activity. Renovation, on the other hand, focuses more on restoring or improving the physical aspects of a building—such as its structure, interiors, and exteriors—often for aesthetic purposes, modernization, or to repair damage. In this book, we will explore both concepts in depth, providing detailed guidance on a wide range of projects, from small-scale updates to large-scale transformations. The book is divided into several key sections: Foundations of Retrofitting and Renovation: A thorough exploration of the basics, including the differences between retrofitting and renovation, the initial assessments required, and how to plan and design a project that meets your goals. Key Retrofit and Renovation Projects: A hands-on guide to specific projects, including structural enhancements, energy efficiency improvements, electrical and plumbing upgrades, and both interior and exterior renovations. Sustainability and Future-Proofing: As environmental concerns grow, this section focuses on green retrofitting strategies, smart home technologies, and designing for health, wellness, and long-term sustainability.
