Passive Solar House Material
Passive Solar Material – What if someone tells you that you can only use sunlight and some special technology to heat or cool your house? The concept of passive solar homes is becoming increasingly popular doing this.
Passive solar homes are designed to get the heating and cooling needs of the sun, wind, trees, or windows and materials used on the walls and roof of houses and the way they interact with the environment. In short, as the name suggests, you do not need to actively heat houses with this system.
This system intends to eliminate the need for boilers, heaters and cooling systems.
Technology in Passive Sun Heating and Cooling
Passive solar homes use the following to meet your heating or cooling needs:
– thermal storage or reflection of materials used on walls, floors and roofs;
– building sun exposure (which depends on the shape, orientation, and layout)
– natural ventilation (which depends on the window, windbreak, orientation)
– the right form and orientation of the house
– Advanced windows, skylights and ventilation elements
– appropriate colors (from walls and roofs to reflect or absorb light effectively) and special elements
sunroom, wing wall, trombe wall, water wall, roof pool, spread glass material;
– other elements depend on design, architecture and landscape.
Passive Solar Material
In other words, passive solar homes use a set of passive solar heating techniques and passive cooling techniques.
Passive solar techniques are primarily a group of designs to apply when you project a new home.
It is impossible to apply most of them to existing homes: You cannot change the orientation and shape of the house, or the materials used on their walls. However, depending on the stage of your home (built or built), you can choose between them to turn your home into the most effective passive solar home.
Use of active and mechanical techniques
The purpose of passive cooling and solar heating is to get natural cooling and heating which will not collide with the use of “active” techniques such as fans or solar water heaters.
You must use it in some cases.
For example fans are very necessary in a hot humid climate, where you cannot fight moisture through natural ventilation or other passive principles.
Most passive solar designs direct it to warm and cool for cold, temperate and dry climates.
Of course there are some general principles that apply in every climate: the right size overhangs, the principle of thermal and mass storage and reflection, shade through trees, but some principles or sizes are very specific for some climates.
Tree shade cannot be used widely in cold and cold climates.
You must analyze the strategy very carefully, according to the microclimate and certain climatic conditions.
On the other hand, in hot and humid climates you must use certain techniques, which are not used in cold climates:
– home orientation to avoid the direct impact of the sun, not vice versa;
– Extension of the use of porches and shade of nets;
– Intense use of mechanical devices to control humidity, etc.
Each climate determines the final passive solar technique, and your plan must reflect it. Some techniques are universal, but others are specific to several microclimate and climate zones.
Although not the most popular among “green” technologies, passive solar homes will be more common in the future because research on them increases and weakness can eliminate them to the highest possible level.
