Abstract: Phase-Change Materials (PCMs) are substances with a high heat of fusion that melt and solidify at a certain temperature range. They are capable of storing and releasing large amounts of energy and have a high capacity of storing heat. PCMs prevent energy loss during material changes from solid to liquid or liquid to solid. They have several advantages such as its self-nucleating properties, and disadvantages such as having low thermal conductivity [4]. There are different types of PCM with a wide range of applications. This paper studies the potential application of PCMs in building energy conservation materials. The analysis shows that the use of BioPCM material as an insulation layer in building can decrease the cooling load by 20% in comparison to a standard one. In addition, this research reviews the program performance to date through conducting a survey to evaluate the HVAC energy consumption efficiency in Residential and Commercial Buildings in Al Khobar City, Saudi Arabia. Forty Buildings were surveyed in October 2014. The survey results showed that fifty perecent of the buildings don’t have insulation and their HVAC systems were more than 10 years old and with lower efficiencies.
