 • While passive solar techniques can reduce annual heating demand up to 25, specifically using a Trombe wall in building can reduce a building’s energy consumption up to 30% in addition to being environmentally friendly.• Similarly, the energy heating savings of 16.36% can be achieved if a Trombe wall was added to the building envelope.• Glare, ultraviolet degradation, or reduction of night time privacy are not problems with a full-height Trombe wall system.
