Solar energy most often associated with electricity production, while at the other side, the heating is also one form of solar energy use. Heating is not too difficult, in this case the efficiency is the key to maintaining your system from damage.
Utilization of solar energy in architecture can be done in two ways: passive and active. Utilization of passive do when solar power does not need to converted first into electricity. Deep utilization of the passive is also included on space heating (using the greenhouse gases) for the region with temperature of the air low, and water heating. Also, techniques to prevent heating the air in the room on the building in the area, including Tropical into the use of the passive type, where component of sunlight, which consists of: light and heat, only used on components’ light ‘it – the need for natural lighting in buildings.
Passive design strategies will be very different between the buildings that are on climate Tropical and climate Sub Tropical / cold. At the Tropical climate, direct radiation from the sun tend to be avoided by building in order to heat gain in the building to be low, so the increase of air temperature in the building can be prevented. While in Sub-Tropical climate, the design strategy is a passive step of the Tropical climate strategy in the acquisition of heat sun tend to be maximized (except in the summer), solar radiation through that fall directly on the building so that temperature increase occurs in the building, considering the air temperature around is low.
In utilizing the solar actively using the photovoltaic, should also simultaneously architect implement the strategy of passive design. Without the application of passive design strategies, energy use in buildings very likely remain high when visual and thermal comfort must be achieved. In situations such as this, the electric power comes from solar power conversion by solar cells does not become too much meaning. With dimensional solar cell panel which needs large electricity for the achievement of thermal comfort and visual on the building difficult to fulfill. Still electrical energy required for engine cooling air with a large capacity, because the air temperature in a high building, also required electricity for lights in the torch-lighting building a dark room when the strategy passive design that lead to the energy savings are not applied. Role of solar power to replace electricity necessary to achieve the building comfort (thermal and visual) finally failed because the building was not designed in such a form so that comfort achieved without the many electric energy consumption. Electricity generated by the photovoltaic possibility will not be large enough to cool down and illuminate the building. In other words passive design considerations for the use of energy in buildings in this case can not be ignored.
In the passive design, objectives of architecture work that would be achieved – that is comfortable and aesthetic, are generally made integral. Each step in the preparation of the components to form the jacket, simultaneous will result in the achievement of buildings comfort and aesthetic. Be not so with the case where the design of active solar cell panels can be arranged separate components with the preparation of building casing. In other words, the achievement of building aesthetic in active design done in a more flexible and separate with the strategy of comfort achievement, although in fact the architects are required to thought to integrate a comprehensive comfort needs with aesthetics – between needs using a solar cell panel with place them on the integrated shroud of the building so that the panels at once can be a building aesthetic element.

Executive Summary about Solar Collector by Armand Hadife
Solar energy is accessible in plentiful places around the world. This high temperature produced can be exploited for heating air or water in houses and buildings
Using solar energy is a natural and affordable approach for spaces or water heating. When using solar power for heating purposes you employ a device that will allow capturing the heat of the sun. This device is called a solar collector. A basic solar collector can be made with no difficulties.
The next step is to find a system to help circulate water or air inside the solar collector. In general, devices like fans and pumps are used to push air or water thru the solar collector and from the storage tank to the house.
For the novice, making a solar collector can be a difficult and demanding project. This is why solar collectors are broadly offered online and in solar products shops.
How to Build a Solar Collector
Executive Summary about Solar Collector by Mick Jeys
Building a solar collector is the best way to save money on electricity bills, and can be used to generate electricity or to heat water. The two most popular uses for solar collectors are to heat water and generate electricity.
Solar Collector To Generate Electricity
Typically known as a solar cell or panel, they are typically made from titanium dioxide, and create electricity through the photovoltaic effect. It is now very simple to build your own generator at home quite cheaply by substituting titanium dioxide with cuprous oxide.
Solar Collector To Heat Water
The most common example of this type can be seen in common solar hot water systems, where the hot water tank is actually up on the roof with the solar collector. Trials are being held in Germany to use solar heated water from the summertime to heat homes in the winter.

Executive Summary about Solar House by Ernest Jarquio
Environmentalists rejoice! What is this new technology that will help save the earth? Why, solar house plans of course.
What Are Solar House Plans?
Well, the new phase in home planning is the plan for a sun-powered home.
Environmentally-Friendly Materials
The designer begins by drawing out the floor plan, planing to use recycled materials, eco-friendly building supplies and Energy-Star electrical outlets. For instance, the concrete slab flooring stores solar heat during the sunny days, then releases it at night, keeping the house warm.
Insulation
The designer uses only eco-friendly items for these tasks, such as recycled wood and green material for the insulation. After all this is planned, they continue onward to Energy-Star appliances and other electronic devices.
Solar Panels
The other panels installed are the thermal water heaters, which provide hot water constantly for the entire home. This hot water is often more reliable than a traditional hot water heater, supplying plenty of heat for the laundry, kitchen and bath.
How to Plan Your House for the Sun
Executive Summary about Solar House by Naomi Kendell
Every house will gain heat throughout the day as the sun shines through its windows.
And during the night as the temperature drops, this same house will lose heat to the outside through its walls, windows and roof.
1. Orientation.
By facing your house to the south (in the northern hemisphere) you will gain the rays of the winter sun. Afternoon sun comes from the west, so rooms like the dining room and living room can be placed on this orientation. The southwest corner of the house will be the sunniest – winter and afternoon sun.
On the northern side of your house, place service rooms.
2. Window Sizing
Out of all the materials your house is made of, windows lose the most heat. There is a balance here, because windows allow sunlight into your house. However even triple glazed glass allows more heat to escape than a well insulated wall.
The first is where your windows face. If you have most of your windows on the northern side, these windows will not get much sun during winter. They will be losing heat, but not gaining solar energy.
There is an optimal ratio of windows:wall for every climate. For instance in temperate climates, a window to wall ration could be: 30% window area to 70% wall area. The other ratio is in windows and orientation.
3. Materials
For instance, highly insulated walls will keep the heat inside your house. When analyzing your heat loss through your windows, you can gain some leeway through insulation. This air forms and insulating layer, slowing down heat loss.
Another way to use materials in your solar house plan is to take advantage of heat storage. It is radiating heat. The floor is insulated underneath to prevent heat loss. A well designed thermal heat sink will stay warm all night long.
4. Shading
Shading is an important part of the solar house plan. This is important not only for heat gains, but for preventing heat gains. In temperate climates as well, shading can be used to keep summer sun out and let winter sun in.
Using our orientation principle: your house is facing south. During the winter the sun angles low and reaches far into the house. This same shading will allow winter sun into your house.
Your latitude effects the angle of the winter sun. In conclusion – solar house plans are a great way to design houses that are warm and comfortable to live in, and save you money off your heating and air conditioning bill.
Using Orientation, Window Placement, Materials and Shading, you can design a house that responds to its environment and creates its own micro-climate of comfort.
