This is Part Two of a four-part project in which students design their dream house. In this second part, students will calculate the construction costs of building the house they designed in part one. They will use Microsoft Excel to create a spreadsheet of all construction costs, material costs, appliances, etc. This involves calculating perimeter, area, surface, area, and volume. Additionally students will conduct an energy audit of their hypothetical house, determining an approximate budget of living expenses such as a gas bill, oil bill, etc. This portion of the project is designed to take about 6 weeks.
