Today, in the great majority of buildings in Morocco, the exterior envelope is not insulated and is therefore not performant from a thermal point of view. This data article describes and analyses a dataset of ratios (cost by square meter that we elaborated for the estimation of the cost of buildings at an early phase of construction. The ratios also allow to take into consideration the generated cost caused by the integration of insulation materials. Based on the primary data that were collected by the economic observatory of the provincial delegation of the Ministry of Urbanism, Habitat, Territory and City Policy, we performed our analysis to come up with our own secondary data which are the ratios of the cost (DH/m2). We focused on four elements of the building envelope namely: the external walls, the windows, the roof, and the floor. The ratios are of a great significance for construction economists and architects allowing them to make cost trade-off between different technical solutions throughout the stages of the building thus, potentially leading to a life cycle cost optimization.
