Building Heat Transfer
Chapter One
Elementary Steady-State
Heat Transfer
From a thermal point of view a building can be looked upon as a modifier of the climate.
For enjoyment and for many forms of manual and intellectual activity, a dry, draught-free
and quiet space is needed with a much more restricted range of temperature than
may be encountered out of doors. The fabric of the building serves as a filter or buffer
generally and to this passive function is added that of its ability to impose a bias on
ambient temperature through provision of heating or cooling. Much of this book will be
taken up with internal temperature in relation to the fabric and supply of heat but it is
convenient to present some brief and elementary account of the factors that lead to choice
of room temperature, measures of severity of ambient temperature as it affects provision
of comfort conditions, and the exchange of heat by ventilation and conduction between the
internal and external environments: these factors determine the heating or cooling load.
