Climate Conscious Low-Energy Tropical Built Environment is a welcome addition to the knowledge on green and sustainable architecture. Both the authors shared their vast knowledge and experience on low-energy and passive solar design. The approach is on the technology adapted and applied to ‘welcoming the sun’ as well as to ‘rejecting the sun’, with the emphasis on the passive elements design. As the world now is facing the rapid increase of population, the architects need to consider the future path of the built environment. A good knowledge in low-energy built environment in order to sustain the well-being of the earth is essential, before considering on the aspects of mechanical components. This book is written in a clear and engaging style to suit all readers, the architecture and built environment students and professions as well as readers in general. As there are many books on this topic, but none emphasize the context of tropical climate. This is the first book on the low-energy built environment within the context of tropical climate. Abdul Malek Abdul Rahman was interested in indoor thermal comfort while researching his PhD topic on “Design for Natural Ventilation in Low-Cost Housing in Tropical Climate”. With a firm belief that to be thermally comfortable without mechanical aids in tropical climates, one should be under shade and receiving ample air movement concurrently, which is not naturally possible. Therefore, he sets out for further researches, literatures and acute observations on this issue. With university research funds, he investigated in hypothesis and experimented on low-cost cooling technologies, attended and read books and references on related topics. Equipped with reliable cameras, he captured ideas and happenings spontaneously to confirm his conviction. He believes that in order to re-examine the philosophy of energy efficient architectural design, one has to detach oneself from architecture and to understand other related disciplines (mechanical engineering, to be exact) in order to value add and upgrade the architecture towards sustainability. He finds the future is very challenging on this issue as population increase is real and that when left uncheck would affect the comfort of human psyche. Technology now is the solution and research must include latest technology available during the particular time of change. Karam Mustafa Al-Obaidi has interest in architectural design systems specifically in the tropics. He focuses on dynamic environment in relation with surroundings. His research is towards energy and how it influences the architectural form. With university research funds, he implemented experimental investigation to obtain reliable examination of the built environment. The future of architecture in terms of technology is challenging in this tropical region. He finds that understanding energy in both consumption and efficiency is limited due to the climatic constraints. Therefore, he believes that creating a platform to integrate related disciplines could provide solutions regarding the issue of energy efficiency. In his opinion, nature is the main source of inspiration, thus designing models that respond to tropical environment could provide comfort and durability for users and buildings.

The fundamental function of buildings is to provide safe and healthy shelter. For the fortunate they also provide comfort and delight. In the twentieth century comfort became a 'product' produced by machines and run on cheap energy. In a world where fossil fuels are becoming ever scarcer and more expensive, and the climate more extreme, the challenge of designing comfortable buildings today requires a new approach. This timely book is the first in a trilogy from leaders in the field which will provide just that. It explains, in a clear and comprehensible manner, how we stay comfortable by using our bodies, minds, buildings and their systems to adapt to indoor and outdoor conditions which change with the weather and the climate. The book is in two sections. The first introduces the principles on which the theory of adaptive thermal comfort is based. The second explains how to use field studies to measure thermal comfort in practice and to analyze the data gathered. Architects have gradually passed responsibility for building performance to service engineers who are largely trained to see comfort as the ‘product’, designed using simplistic comfort models. The result has contributed to a shift to buildings that use ever more energy. A growing international consensus now calls for low-energy buildings. This means designers must first produce robust, passive structures that provide occupants with many opportunities to make changes to suit their environmental needs. Ventilation using free, natural energy should be preferred and mechanical conditioning only used when the climate demands it. This book outlines the theory of adaptive thermal comfort that is essential to understand and inform such building designs. This book should be required reading for all students, teachers and practitioners of architecture, building engineering and management – for all who have a role in producing, and occupying, twenty-first century adaptive, low-carbon, comfortable buildings.

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. This is the first technical guide from the Council on Tall Buildings and Urban Habitat's Tall Buildings & Sustainability Working Group looking in depth at a key element in the creation of tall buildings with a much-reduced environmental impact, while taking the industry closer to an appreciation of what constitutes a sustainable tall building, and what factors affect the sustainability threshold for tall.
