Energy and environmental performance of passive Trombe wall
The energy and environmental performance is compared for buildings with and without Trombe walls.The indicator for environmental performance is the total annual primary energy demand that is a sum of primary operating energy for heating during winter and the embodied energy consumed by using the Trombe walls.Two Trombe walls are used at the south side of a “Motzart house located in Lyon,France.The house satisfies the French thermal regulation.The performances of several constructions of Trombe walls are studied.The total primary energy consumption by Trombe walls may be lower when the core material has lower density and lower embodied energy.The heating by electricity yields much higher values of the primary energy consumption than that of the heating by using natural gas.In the case of electricity heating,the optimum thickness of the core layer is around 0.35m,and for natural gas heating this value is around 0.25m.When the building with Trombe walls is used,the annual final energy savings during heating are around 20%of the final energy used for heating of the basic building.For the electricity heating and optimum core thickness,the energy ratio is around 6 and for the natural gas heating around 3.For the electricity heating and the optimum core thickness,the energy return period is around 8 years and for the natural gas heating around 18 years.The overheating of the house is negligible due to installation of Trombe walls.
