In summer the breezes, blowing from the sea during the day, can easily cross the building thanks to its orientation and to the inner cavities

STRATEGIES TO REDUCE THE HEAT ISLAND EFFECT

STRATEGIES TO REDUCE THE COOLING DEMAND In summer, shops’ temperature is cooled down through thermal mass of concrete structure and the shading coming from the ramps.

COMPACT SHAPE to reduce heat loss

In a cold environment the minor surface area to volume ratio reduces heat loss
