Final answer:
Clancy likely chose materials such as tile, concrete, and brick for their ability to store heat from the sun, a key feature in passive solar home design that aids in natural heating and reduces energy use.
Step-by-step explanation:
Clancy MOST LIKELY included materials such as tile, concrete, and brick in the blueprints for a home that will use passive solar home design because they will help store heat energy from the sun. These materials are known for their thermal mass properties, which means they have the ability to absorb, store, and later release heat. This characteristic is incredibly beneficial in passive solar home design, as it contributes to natural heating, reducing the need for conventional heating systems. Additionally, strategically positioned south-facing windows can admit sunlight during the winter, while overhangs can shade these windows during summer to prevent overheating. Pairing these design elements with materials like concrete, which serves as an excellent thermal protector, results in homes that are not only environmentally friendly but also cost-effective in terms of energy consumption.
