Passive Solar Energy

Energy needs in our rapidly developing world constantly escalate. Especially after the
industrial revolution these needs have been satisfied of fossil fuels. However, energy
generation by fossil fuels bears byproducts causing serious environmental damage.
Inattentively excessive usage of these sources specifically brings about great danger to
nature and our future. Currently the effects of the damage are observed explicitly and
have been disturbing our daily lives; ergo, immediate measures ought to be taken and
regulations of energy generation and consumption to be made. Executing these
regulations is relatively easier for developing and evolving countries such as Turkey with
respect to developed countries.
Environment friendly energy generation techniques need to be sought and examined.
Existing energy needs should be covered with sources which do not harm nature and their
utilization should be improved. Meanwhile in order to achieve proliferation and adoption
of alternative sources by the society certain practices need to be introduced.
The sun is the biggest and cleanest renewable energy source we have. Usage of sun energy
instead of fuel for heating of the buildings is investigated primarily in this study. Taking
advantage of the fact that solar radiation exposure period is long in Turkey due to
geographical properties, passive use of the sun is investigated thoroughly.
Examinations have been done to lay out the results of passive use of the sun in conditions
of Turkey. Buildings from places with similar weather conditions to Turkey and buildings
constructed in Turkey were analyzed with different methods by computer software. As
the output report of the analyses were compared and evaluated, the studies were
concluded.

For millennia, humans relied almost entirely on renewable energy (RE), largely biomass, for their energy needs. Over the past century, fossil fuels (FFs) have not only largely replaced RE, but have enabled a many-fold rise in total energy use. This FF dominance changed the way we think about and accounted for energy use. If (as at present) the world essentially continues to ignore climate change, eventual resource depletion will force conversion to RE and, perhaps, nuclear energy will once again have to provide most of the world's energy use. However, the change is more likely to come about because of the urgent need for climate change mitigation. At present, primary RE electricity accounting is done by calculating the FF energy that would be needed to produce it. But as FFs disappear, this approach makes less sense. Instead, a new approach to energy accounting will be needed, one that allows for the intermittent nature of the two most abundant RE sources, wind and solar power. Surplus intermittent RE might be converted to H2, further complicating energy accounting. An additional complication will be the treatment of energy reductions, especially from passive solar energy, likely to be more important in the coming decades. This paper is a review of the evidence to try to determine the best approach to future energy accounting.

The present society utilizes the electrical energy for their comfort. This electrical energy is majorly obtained by burning the fossil fuels. These fuels are decreasing in a dramatic rate and it is also contributes to the pollution. Throughout the sun's daily and annual cycles, thereby the reducing the dependence of energy consuming mechanical and electrical systems of heating and cooling. Based on the analysis of data collection, Passive solar design for home helps to reduce the consumption of electrical energy by utilizing the solar energy. Passive solar design is a green concept which is aimed to utilize the maximum solar energy in the form of heat to maintain interior thermal comfort by designing windows, walls and floors of the homes to collect the solar heat from the sun in winter and reject it in the summer. This papers presents the critical literature review on benefits due to passive solar energy system in building

Passive solar energy is actually the principle design aspect has been playing a significant role in architecture in the recent years. Commercial buildings because of their large spaces have been high-energy consumption, although by taking benefits of passive solar strategies, energy consumption reduction in these kinds of buildings will result to cost decrease as much as possible. The microclimate also environmental conditions generally both known to get physical and emotional influence on human and, as a result, of main importance in building design improvement.
The purpose of this study is to focus on energy efficiency in Onder Commercial building in Famagusta, Northern Cyprus. This paper provides standards and proper information for better organization in pre-design stages to create energy efficient buildings to make comfort zone inside by the help of applicable passive solar energy strategies in commercial buildings.
Passive solar design is unique and essential concept for designing which can be used in Cyprus commercial buildings. The necessity of designing on the passive solar is that Cyprus has not any kind of energy sources by its own self. As the passive solar energy approaches and climatic characteristics of Famagusta located in the northern hemisphere, the building ought to be orientated due to north-south. The reason for this method is actually south facade creates the best vertical surface to take advantages of passive solar energy. Proper sun shading devices by the aid of plants and trees at the west and east of the building, will improve energy consumption in summer. Furthermore, the correct use of south facade for windows, and minimizing the windows on the west and east facade are some solutions to have comfort inside in cold months. Utilization of double or triple glazing windows is another solution to prevent heat loss of interior spaces in winter. Besides, the cost reduction of energy consumption can be another priority for using of passive methods in commercial building. In addition, optimum ventilation will accomplish by correct usage of small opening in north facade of the commercial buildings. By applying these strategies, customers and employees will enjoy of indoor comfort condition in both hot and cold seasons.
