What is the function of a Trombe wall?

• A. To cool ambient air in a space
• B. To heat water for a hydronic system
• C. To absorb heat from the sun and warm the air
• D. To support structural integrity

Answer: (C)

The function of a Trombe wall is primarily to absorb heat from sunlight and subsequently warm the air within a space. This passive solar design element typically consists of a thick, south-facing wall made of materials with high thermal mass, such as concrete or masonry. When sunlight hits the wall, it is absorbed and stored, which then radiates heat into the interior during the evening or cooler periods, helping maintain a comfortable temperature without the need for active heating systems. This method of heating is particularly energy-efficient, as it utilizes natural sunlight to provide warmth, reducing reliance on conventional heating systems that may consume electricity or fuel. The design effectively captures solar energy and converts it into usable heat, thereby contributing to energy conservation and sustainability objectives in building practices.
