Performs yearly simulations of a building life cycle, in order to provide mechanical, energy and architectural engineers or architects with environmental indicators (e.g., global warming, acidification and eutrophication potentials, exhaust of natural resources etc.). The Ecoinvent database is used for material fabrication and other processes (energy, water, waste, transport). novaEQUER is linked to the energy simulation tool COMFIE. Replacement of components at the end of their life is automatically accounted for.
