Building sector is one of the largest primary energy consuming sectors and contributes substantial atmospheric
emissions. With growth and improvement in technology, the energy consumption and comfort levels have increased exponentially.
Minimizing energy consumption in all energy consuming sectors have become progressively imperative
worldwide because of the many important issues, such as; increase in energy demand, energy security, rising energy cost
and the need to reduce the environmental damage of energy consumption. In building sector there are various opportunities
available to have a better indoor thermal comfort conditions and to reduce energy consumption by using advance materials.
The use of advance and innovative materials (e.g. Phase change materials (PCMs), thermochromic materials, radiant
and thermal barrier materials) instead of conventional materials is advantageous in achieving better indoor thermal
comfort and saving energy, therefore it is imperative to pay attention to the selection of building materials. Different materials
are used in different components of buildings; hence it requires improvement in all materials to have better indoor
conditions. In this paper, a review of the latest patents and literature on advance building materials has been discussed.
The study reveals that the use of advance materials is promising in energy saving and better indoor thermal comfort as
compared to the conventional building materials.
