passive solar design
Passive solar design can improve the energy efficiency of the building in three areas: heating, cooling and lighting. Lighting
A good use of lighting within buildings reduces or eliminates the use of artificial light during the day, which saves considerable energy and, consequently, less environmental damage , if well designed, daylighting can create conditions life more pleasant and healthy.
Currently there are several mechanisms to capture and redirect natural light inside buildings, and to reduce excessive levels of clarity around the windows and provide a more homogeneous distribution of natural light.
Some of these mechanisms, patios, reflective shelves, skylights and tall windows, can have significant results in a project.
addition to other devices that can provide shade, and materials that control the intensity and properties of natural light and heat flows through the windows.

The shelf solar
The windows are a lot of energy from the sun. Most of this is lost in one area, and direct sunlight is the main cause harmful discomfort glare on desks and computer monitors. In fact, a well-oriented single window can light up 20 to 100 times the unit area. This light can be a nuisance if concentrated in one place, but very helpful if distributed to all parts of the room equally. Shelves are
solar visible light bounce to the ceiling, reflecting and deepening this light inside a room.
lighting of office space and breakout rooms, provide a natural sheen to the construction and reducing the need for daytime running lights.
In other words, you can reduce energy consumption by turning off lights and perimeter of a building using natural light to illuminate the space, however, without the use of natural light solar shelves not much illuminating. Solar Shelves allow penetration of up to 2.5 times the distance between the floor and the top of the window and the most advanced up to 4 times that distance.
solar Shelves should be light and installed horizontally. The upper surface can be painted with gloss, matte or textured and combined bottom the decor of the room. The type of paint is important. A glossy paint will reflect light into the sky at the same angle with the shelf that reaches the light creating a direct and highly annoying. For a more diffuse light using a matte or textured paint as this allows light to reflect at different angles throughout the room.
Advantages:
• Improving the quality of sunlight
• Conserve energy by allowing perimeter lights are off.
• Improved environmental quality and increases productivity.
The shelves are best positioned on the north side buildings (southern hemisphere) to maximize sunlight.
is important to design the shelves according to where they will be used, as these can also be used in combination with other elements to help maximize the use of sunlight such as external shelves, blinds, etc. In addition, the shelves are not very useful in cities with lots of cloudy days and not get too much sunlight.
