Abstract
The paper attempts to present a project of a low energy house which uses renewable energy to cover the heating and domestic hot water needs. The heat demand of the house for the winter and domestic hot water needs are calculated. The global coefficient of thermal insulation and energy consumption for heating and domestic hot water are computed, too. The calculation methods are those recommended by the current Romanian regulations. The obtained values are very small and the house can be seen as a low energy building.
