Summary Adaptive Thermal Comfort: Foundations and Analysis Humphreys, Nicol and Roaf
Adaptive Thermal Comfort: How to Design Comfortable Buildings Roaf, Nicol and Humphries
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 timely-book is the first in a trilogy from leaders in the field which will provide just that. It explains, in a clear arid comprehensible manner, how we stay comfortable by using our bodies, minds, buildingsand their systems to adapt to indoor and outdoor conditions, which change with the weather and theclimate. The book is in two sections. The first introduces the principles on which the theory of adaptivethermal comfort is based. The second explains how to use field studies to measure thermal comfort inpractice and to analyse the data gathered
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
