Cavemen were not slow in seeing the benefits of thermal mass. They quickly realised
that only a few meters inside a cave, the temperature stabilises and the influence
of the outside ambient temperatures diminishes.
In ancient cultures with hot climates such as Persia, the building fabric and form
was designed to provide comfort against the environment. Buildings featured thick
walls, small recessed windows and arches providing solar shade.
In today’s building stock, thermal mass has been largely ignored as a means to provide
In the last century, coal, gas and electricity offered relatively cheap methods to
provide secondary heating and cooling systems.
With governments now setting targets for buildings to be nearly zero carbon, architects
and engineers are having to re-evaluate design concepts and techniques employed.
