As we saw in the last post, in temperate latitudes, the amount of solar energy reaching the earth varies greatly through the year. Ultimately, this is why we have seasons. While we want to maximise solar heating in winter, during the summer months we may need to limit the amount of solar energy entering the building, in order to avoid overheating. A classic way to do this is with roof overhangs. As you can see… Leer más »Controlar la energía solar en el edificio

The sun is the source of all life on earth. We can also use it to keep our buildings comfortable, provided we understand how, and when, solar energy reaches our site. The apparent motion of the sun across the sky depends on latitude. At the equator, the sun passes nearly overhead, and follows a steady east-west path, regardless of the time of year. Whereas at the poles, the sun travels round and round the sky… Leer más »Captando energía solar en edificios

How can we build in a more environmentally friendly way, while at the same time making buildings cheaper to run? One way is by using the sun and wind to heat, cool, light, and ventilate them, thus avoiding the use of fossil fuels. This can be done by applying a set of techniques—known as passive solar design, or bioclimatic design—many of which have been used in traditional buildings for centuries. Like, for example, this house… Leer más »Introducción a los edificios solares pasivos
