Heat: Ways the Human Body Gains or Loses Heat to its Environment

This document discusses the ways in which the human body gains or loses heat to its environment. It explains the mechanisms of evaporation, radiation, conduction, and convection. It also explores the main paths of heat loss in an uninsulated brick veneer house in Sydney during winter. Additionally, it calculates the thermal conductance of a cavity wall and discusses the thermally efficiency of cavity brickwork in housing in Australia. Finally, it describes five strategies for passive solar cooling in hot dry climates and how angled louver blades can be designed to manage the entry of direct sunlight into a building in a location like Sydney.
