Energy efficiency regulations encourage lightweight building constructions and super-insulation, which are not suited to temperate climates where the aspects of comfort and summer cooling consumption are dominant compared to winter consumption. The aim of the paper is to compare the annual behaviour of different constructive technologies in a temperate climate through an analytical study of three buildings soon to be constructed in Ancona (central Italy).

Abstract

Energy efficiency regulations encourage lightweight building constructions and super-insulation, which are not suited to temperate climates where the aspects of comfort and summer cooling consumption are dominant compared to winter consumption. The aim of the paper is to compare the annual behaviour of different constructive technologies in a temperate climate through an analytical study of three buildings soon to be constructed in Ancona (central Italy). These buildings are equal in dimension and distribution and they differ in the adoption of three constructive technologies (widely used in the Italian current practice), characterized by a different configuration of inertial mass-thermal insulation. The three buildings have been compared according to different points of view: energy performance, comfort, environmental sustainability. The energy performance has been studied through analytical models in semi-stationary and dynamic conditions; the comfort has been analyzed through the Fanger’s PMV model for the winter season and through the adaptive comfort model for the summer season; energy and environmental sustainability have been addressed through the life cycle assessment (LCA) of the materials and the cost-benefit analysis. In Mediterranean climates the masonry represents a good solution with lower consumption during the summer, minimum exploitation of environmental resources and affordability.
