The use of proportion in design for energy and resource efficiency in buildings varies depending on the design goals and context of the building. However, some common ways in which proportion is used are:
1. Building envelope: The proportions of a building's exterior envelope can significantly impact its energy efficiency. For instance, using larger and strategically placed windows can provide natural light and reduce the need for artificial lighting, while too many or poorly placed windows can increase heating and cooling loads.
2. Glazing-to-wall ratio: The ratio of glazing to wall area also affects a building's energy performance. A higher ratio may allow more natural light and views, but can increase unwanted heat gain or loss. Proper proportions can be achieved by designing shading elements or using high-efficiency glazing systems.
3. Room proportions: The size and shape of rooms can also affect energy performance. Longer, narrow spaces can be more difficult to ventilate and heat/cool, while rooms with excessive volume can require more energy to maintain comfortable temperature levels.
4. Material usage: The proportion of energy-efficient materials used in building construction can also play a key role. For example, insulation materials can significantly reduce heat loss/gain, and the proper proportion of insulation material can reduce the energy input for heating/cooling.
Overall, the successful integration of proportion into the design process results in buildings that are resource-efficient, aesthetically pleasing and cost-effective to operate over their lifespan.
