Which of the following elevation drawing strategies will best achieve the goal of maximizing natural lighting while considering the site and climate constraints?
Use small, high windows all around the building for consistent lighting.
Install windows only on the east and west sides to avoid direct sunlight exposure
Place most of the windows on the north side of the building to take advantage of the views.
Place larger windows on the south-facing side and smaller windows on the north side to maximize sunlight during the winter.
You have been given an elevation drawing of a residential building with a steep roof pitch, large windows on the south-facing facade, and a flat roof section for a solar panel installation. How would you adjust the design to improve both aesthetics and energy efficiency?
Lower the roof pitch to make the roof appear less steep and add more windows to the north side.
Maintain the steep roof pitch, but add shading elements such as overhangs to control solar gain while keeping the large south-facing windows.
Flatten the roof entirely to optimize space for solar panels, but remove the south-facing windows to reduce heat loss.
Increase the number of windows on all facades to balance lighting, and remove the solar panels in favor of better insulation.

The dimension can be chosen arbitrarily as long as it is greater than the minimum required by code.
The dimension should be determined by the foundation type, irrespective of the weight distribution of the building.
