Thermal mass can improve building comfort by reducing temperature fluctuations when used appropriately with passive design features. It works best in reducing energy usage for heating and cooling systems. However, thermal mass used incorrectly can increase energy demands and decrease comfort by radiating too much heat back inside.

The Role of Thermal Mass in Sustainable Design
Thermal mass offers building designers the opportunity to improve the comfort of any
building that experiences temperature fluctuations throughout the day, both in summer
and winter. When it is used appropriately in conjunction with other passive design features,
thermal mass can play an important part in sustainable design, particularly in reducing the
energy consumed by active heating and cooling systems. If, however, thermal mass is used
incorrectly it can become an enormous energy and comfort burden to the occupants of the
space, e.g. in winter it can put extra demands on the space heating loads and in summer
prevent the building from cooling sufficiently if too much heat is being radiated back into
the building.
