This finding demonstrates that energy labelling was fruitless to deliver a good message in encouraging consumer buying decision. Energy labels have to be understood, trusted and valued as a tool for consumers’ decision making.

Based on an elastic behavior and the Dunkerley formula, a simplified expression is proposed, which takes into account the geometrical and the mechanical characteristics of the structure. Following this development, the period value is a function of the number of floors of the considered structure. It is in good agreement with that obtained by the FEM that uses numerical methods requiring a sophisticated and more complex process.
