Solar Orientation and Exposure

What is Solar Orientation?

Solar orientation is a very important factor that is required for sustainability in the determination of alignments such as building and other same type of alignments. This will ensure suitable placements that will enhance sustainability in the use of energy in heating, cooling and also in lighting (Pizzutti et. al 45). Lets take for example, in terms of building the position of the building will either affect the sustainability and he use of the solar power which therefore needs better and reliable positioning so that all these shortcomings can be dealt with promptly (Larice 80).

What is Solar Exposure?

For solar exposure, this contemplates on the angle of the sun during different seasons of the year. This will be through the angle of elevation from the sum to the buildings and the effect that they cause such as green house emissions effect (McKenzie 33). The sun is at a different angle during different seasons such as during the summer sun is at high angles that during the winter and other yearly season (Hunt 342). Therefore in the sustainability side during infrastructure it will help in building houses in a manner that they will ensure that there is sustainability of heating and cooling during different seasons (Thompson 67)). Under this one can get different perspectives about the sun such as the Passive day lighting where a house for example, will be built in a manner that the house will be receiving natural lighting so that there can be effective circulation of energy and reducing the overall energy consumption to ensure sustainability(Cazayoux 234). Passive solar street orientation gives the plans on how to give structure that will respect the solar alignment leading to sustainable solar usage skills and alignment of each building giving a significance saving for sustainability.

Active solar building orientation it is very important to ensure that the houses are built in a manner that they will ensure adequate and effective collection of voltages by the devices that are used through their configuration to the sun rays (California Energy commission 134). Therefore in order to ensure there is the correct sustainability of the solar there must be enhanced ways through which photovoltaic's instruments will get the overall opportunity to get the correct measure of the sun so that it can give effective production of voltage leading to adequate power supply within (Bodart 42).

Tables and Graphs

This can be very evidential by the look from the following tables and graphs. This is featuring a solar water heater for providing hot water system in the house for heat sustainability within the ecosystem (McGee 89). This is determined by the number if inhabitants situated in a particular household.

No of people in the household Area of solar collectors Volume of solar storage tank Indicative initial investment
2-3 4-6 m2 200-350 liters 3809-5,079
4-5 8-10 m2 350-600 liters 5,079-7,618
6-7 10-12 m2 600-1,000 liters 7,618-8,888

Graphs showing the solar energy consumption for heating, cooling and the total solar orientation including the different of facade opening in consideration to colorless glass

All the data is in consideration to colorless glass where the first graph is for the energy consumption for heating annual relative solar orientation while the second is for the annual consumption for cooling energy in relation to solar orientation (Guy 12). The third is the grand consumption of energy in relation to solar orientation.


For sustainability of the solar energy, adequate measures need to be employed so that the heat energy from the sun can be used to subsidize various uses of the other forms of energy leading to the lowering in the cost of energy use and ensuring that there is sustainability of the energy. The photovoltaic's require enough show room in places where there are no shades so that they can receive full intensity of the solar energy for storage of adequate voltages that can sustain and subsidize other types of energies.
