Final answer:
Information about the size and location of structural openings is found in construction drawings. Measurements for creating a to-scale diagram are taken with a tape measure and then scaled down to fit on paper. These details are critical for building design and calculating energy efficiency.
Step-by-step explanation:
The information about the location and size of the window headers, cells, door headers, and heights of various openings above the subfloor is typically included in a set of construction drawings or architectural plans. When planning to open any walls for windows or doors, it is essential to draw a to-scale diagram of your room. To start, you would measure the length and width of your room with a tape measure. After that, you would convert these measurements to a scale that fits on paper, as in the example where 5 centimeters on paper represent 1 meter in reality.
When considering the thermal properties of a structure, as in the house with a square footprint example provided, you calculate the total wall area and then subtract the area taken up by windows to determine the remaining wall area. The heat loss measure is then calculated, taking into account the different thermal properties of materials like windows and walls/floor/ceiling.
In practical application, these details are crucial for effective building design, ensuring structural integrity, and energy efficiency.
