The House in Miramar by 'e|348 Arquitectura' has a louver-panelled design on the outside upper deck, which opens seamlessly to allow even more light through. When closed, the small slats enable a constant flow of air from the outside, and even some natural rays. This ensures that the cost is lower for air conditioning in the house, as the abode is located in Portugal where the weather is quite hot.
This is a house that really makes the most of its location, instead of fighting the natural elements with more costly manmade functions. By inserting these moveable louver panels, the residences are able to take in the fresh air without even going outside, as well as enjoy a bit of extra heat if it's ever needed.
