  7. Abstract:
  8. Shortage of energy sources in the new decade along with the increasing level of greenhouse gas emissions urges researchers in the field of energy to explore for the new source of energy as well as seeking for methods for usage of available energy resources more efficiently. Therefore, development of building with low level of energy usage may significantly reduce the need for grid energy. This can be met with new construction materials to reduce the energy consumption, using renewable energies sources such as solar and wind as well as design and development of materials with capability to store energy. The use of materials which can store energy and release it when needed has been considered as an efficient approach aiming to reach for building with zero energy level. The present work investigates the use of phase-change materials (PCMs) in building in order to reduce the energy demands. A mathematical modeling based on the enthalpy formulation of the latent heat energy storage materials has been developed. The effect of conductivity and thickness of a typical PCM on temperature distribution and phase changed fraction is investigated. The performance and functionality of the proposed system, has been illustrated by considering a typical residential building located in Tehran. It is concluded that using PCM materials may potentially reduce the energy level in the residential building
