Design Lessons from History

Oil heartlands of Abu Dhabi, Dubai, Doha and Iran’s coast will experience higher temperatures and humidity than ever before on Earth if the world fails to cut carbon emissions, according to a recent study. While air-conditioned homes and offices provide respite from the heat, architects are looking to history to find how civilizations battled the hostile conditions.

Historically, the inhabitants of the Gulf were either farmers living near oases in agricultural villages, Bedouins living in tents in the desert, or urban dwellers living in cities. Given the global trend toward urbanisation, it makes sense to take a closer look at how the latter group coped with the heat. Traditional buildings in the gulf’s cities and villages are designed to maximise shading, reduce thermal gain of the sun radiation, regulate building temperature and enhance air circulation. These effects are achieved through a clever combination of building materials, placement and design.

Natural materials such as limestone and mud – in some cases mixed with local desert plants – provide a construction material with the capacity to regulate building temperatures. The material itself is capable of absorbing moisture in humid conditions, which can later evaporate during hot and sunny days to provide a slight cooling effect. And the sandy texture and colour of the buildings reduces both the absorption and emission of radiating heat.

Traditional buildings are placed adjacent to one another, with narrow roads and alleyways in between. This means that the ratio of the area exposed to the sun relative to the building’s total volume is minimised, which in turn limits heat increases during the day time.

Many traditional structures feature an internal courtyard, often containing trees and a water well. The courtyard is typically surrounded by rooms or walls on all sides, maximising the area in shadow throughout the day and creating a space for socialising in the evenings. When the sun bears down at midday, the courtyard works as a chimney for the hot air to rise and be replaced by cooler air from the surroundings rooms – this promotes air circulation and creates a cooling effect.
