According to the study by Jiang and Zou, which morphological indicators were analyzed for their correlation with building energy consumption?

The study analyzed twelve morphological indicators; the named ones include building floor area ratio, building density, average height of individual buildings, and weighted average height of building area. Other indicators that appear in the reported analyses include unit area, average building perimeter, standard deviation of building height, average distance between buildings, average shortest distance of buildings, and area.

According to the abstract, Jiang and Zou examined twelve morphological indicators for correlation with heating, cooling, and total building energy consumption, naming building floor area ratio, building density, average height of individual buildings, and weighted average height of building area. The paper's later correlation and ridge regression results also refer to additional indicators such as unit area, average building perimeter, standard deviation of building height, average distance between buildings, average shortest distance of buildings, and area. The provided text does not list all twelve indicators at once, so the full set is not fully enumerated in the excerpt.
