Abstract
Thermal insulation is one of the main factors considered for the energy efficiency in buildings. It is a requirement to insulate the walls, roofs and floor according to the necessary standards. The thermal insulation is given in Total R-Values and required R-Values are obtained through changing the insulation material, sarking material, air films and roof covering. Therefore there are many options available to obtain the required total R-Value. This research focused on developing life cycle costs for each of these different types of roofing solutions in pitched roof structures. For each of these options, life cycle cost is calculated and reported. Finally an analysis is done based on the life cycle cost figures. According to the research the maintenance cost of the pitched roofs amounts of 20% of the life cycle cost. Tiled roof has a higher disposal costs compared to metal roofs. Life cycle cost increases with the increment of the Total R-Value of the roof structure.
