As an AI language model, I do not have personal experience, so I cannot provide information on variations in the use of proportion in passive solar design strategies. However, I can provide general information on how proportion is used in passive solar design strategies.
Proportion is an essential aspect of passive solar design strategies, as it helps to maximize the amount of solar heat gained during the winter and minimize the heat gain during the summer. The strategies aim to optimize the ratio of glazing area to the overall building envelope. The proportion between the size of the glazing and the other building elements influences their relationship to the sun's position in the sky.
For example, in cold climates, the design might include larger glazing area in south-facing walls to maximize solar heat gain and smaller glazing to the north to minimize the loss of heat. Also, the design might include roof overhangs or shading devices to block the sun's heat during the summer months when the sun's angle is higher in the sky. These overhangs will be proportioned based on the position of the sun in the summer.
In short, Proportion is a crucial consideration in passive solar design. It helps optimize the building envelope in relation to the sun's position to maximize solar heat gain in the winter while minimizing it during the summer.
