Twenty first century standards for thermal comfort : fostering low carbon building design and operation [PDF]

open access: yes, 2010
Nearly 50% of energy consumed in the developed world is consumed in buildings. Despite regulation intent, many new buildings are energy profligate. Thermal comfort standards are partly responsible for this increase in consumption. In this volume, Roaf et
