Adaptive Thermal Comfort: Principles and Practice
Abstract
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.

“At the same time, research has shown that people accept much broader thermal conditions than anticipated by above standards [1,3,14,47], andtheir perception of thermal conditions is much more dynamic [48–51].”

“While these seven variables are able to explain part of the variance seen e.g. in Figure 1 by Nicol et al. [1], which is based on operative temperature only, there remains a high variance even when all six variables are considered.”

In the citing paper
“The data presented uncovers the diversity of thermal perception: on the one hand, people are feeling comfortable (4 on y-axis) between 20°C and 28°C. On the other hand, in the range between 22°C and 28°C votes between ‘much too warm’ (7 on y-axis) and ‘much too cool’ (1 on y-axis) can be found for any given temperature.”

“Not surprisingly, the regression of comfort votes against operative temperature explains only 16% of the observed variance in the data.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
