IDEAS TO PROTECT AND TAKE ADVANTAGE OF SOLAR RADIATION IN YOUR HOUSING
Does solar radiation affect your home a lot? Do you want to minimize its effect on your house with passive actions?
Summer is coming and it's time to update the creams on your dressing table and take out the sunscreen so that your skin does not suffer.
What if we think about our homes? Don't you think that our buildings also suffer from solar radiation?
In this post We are going to give you some ideas to protect the most sensitive parts of your home, with passive systems that do not involve energy expenditure and that also take advantage of the synergies of the environment.
WHAT ARE SUN PROTECTIONS
Solar radiation is the passive source that warms buildings in winter, advantage that in summer becomes a disadvantage, so sunscreens are vital to make the most of thermal gains in winter and minimize them in summer.
We differentiate between two basic types of protections, the fixed ones, and the mobiles
The fixed protections are cheaper plus do not need maintenance, they must stand horizontal, but they will only protect us if we install them in South orientation, to cover ourselves from the midday sun. This is because the sunlight in this orientation is very low in winter, allowing us to receive energy charge; while in summer it is much higher, providing shade to glazed surfaces.
Mobile protections, how graduated blinds, among other, they have one shorter service life and higher maintenance cost, But they are ideal for orientations this and west. This is because the difference in height of the sun is practically the same in summer and winter, which implies that protections should appear and disappear depending on the time of year.
Another factor to consider: SOLAR REFLECTIVITY
What color am I going to paint the facade of my house? What material should I choose for the cover?
The choice of finishing materials for facades and roofs are very important details to consider, since they have a great relationship with the capture of solar energy, regardless of its aesthetic appearance. These decisions will determine how our building will suffer energetically with each one of them..
The Light colors reflect radiation, while the dark colors concentrate it. So we have pictures of whitewashed Mediterranean villages and towns dark of the north they use the blackboard and the dark stone. In the same way the roughness of the materials is another factor of affects to a high degree, since very rough materials scatter radiation, Meanwhile in the smooth ones the reflectividad can get to be null.
