Abstract: The compactness of a building depends on its shape, its size and its contact properties.The main objective of this contribution is to investigate the impact of the building' height on energy needs.The assessment criteria will be based on a well-defined lifestyle and occupancy scenario, the indoor comfort temperature and the required energy consumption.The results obtained from the regression models and their relative simplicity allows them to be used as a tool for estimating energy needs, energy savings and investment-return time.The absence of insulation would result in an energy saving of exactly 26.77%, by raising a single house to one-storey building.It will be more substantial savings (more than 40%) by exceeding the fourth floor.In the case of an insulating layer of 10 cm, an energy gain of 21.17% can be saved by varying a single house to one-storey building.The reduction in energy needs exceeds 35% but remains below 38.5% for buildings which are over three storeys high.Generally, the investment-return time is between 49 months and 44 months, and it is inversely proportional to the number of storeys in the dwelling.It is therefore necessary to favor large buildings to rationalize energy consumption.
