investigating the methods for using solar energy in residential and recreational complex design of the quru gol (tabriz).
The location selected in this study is suitable for residential-
Recreational use of sustainable design for the following three reasons: 1.
The Gol pond causes humidity and reduces the dryness of the site of the complex.
Due to the large specific heat capacity and the high heat storage capacity of water, water can cause the temperature to drop and reduce the temperature difference between day and night in this area, the presence of water leads to movement and activity of set. 2.
This place is located outside the metropolitan area, away from the environment, noise pollution and heavy traffic. 3.
Due to the limitations of the city, it can be designed to be low in height and to use maximum sun reception on the roof.
According to the features mentioned, the design of this website is fully in line with the features of sustainable buildings.
One of the most important issues in this complex is the energy supply required for different uses.
These include: electricity for production, energy for space heating, hot water, pool water, laundry and air ventilation.
Today, human beings are faced with problems such as environmental pollution, heavy rain and high-speed decline of fossil fuels, so it is better to use newer environmental energy sources.
Therefore, in this study, different and available ways of using solar power in Iran and Azerbaijan will be investigated.
This has been tested in the world and in developed countries, and many cases have been implemented, and in Iran, some activities have been done in this regard in the past 20 years, used in some residential or industrial projects but not
Residential buildings such as hospitals, schools, hotels and offices are not feasible for any project.
At present, the hotel industry is one of the potential thermal energy demanders. It can combine solar-assisted heating systems, which can not only reduce the dependence on fossil energy, it is also possible to improve such buildings as their tourism by obtaining green labels . 2.
Search method: the learning method is descriptive-
The type of analysis and research is theory-usable.
Methods of data and literature collection include field and library research, websites, articles and literature.
In this way, the appropriate methods and strategies are analyzed and then matched with the ecological conditions of the research site. After the evaluation results come out, the data will be used for the design of this residence. -

Discussion: photovoltaic systems are one of the most promising renewable energy technologies. Photovoltaic (PV)
It is a truly elegant way to generate electricity on site, directly from the sun, without worrying about energy supply or environmental harm. These solid-
The National equipment simply uses sunlight to generate electricity without maintenance, no pollution and no material consumption . 3. 1.
Introduction to solar system: 3. 1. 1.
Active solar system (dynamic:)
Electrical and mechanical systems are used in active solar systems that realize and transmit energy.
Such as photovoltaic system (
Solar thermal collector (
Solar water heaters, etc). 3. 1. 2.
Photovoltaic system: one of the types of systems that generate electricity from solar energy.
In these systems, the energy of sunlight is directly converted into electric energy using solar cells.
The solar cell is a semiconductor made of silicon material, which is the second rich element in the Earth\'s crust.
Sunlight exposure on photovoltaic cells leads to a potential difference between positive and negative electrodes, which is the current flow between them.
The efficiency of solar cells includes the ratio of radiation energy to the generated electrical energy, which can be changed according to the type and design of the battery, which has different methods for improving energy efficiency.
Because the energy of these cells is sunlight, the location of these cells is part of the building and there is a suitable area for direct sunlight . 3. 2.
Passive solar system (Static)
: Unlike active systems, static systems no longer require other interface systems, and structural elements act as receiving components, absorbing and allocating energy.
Sunny windows, tromp walls, greenhouses, solar roof, wind tower, basement, etc. 3. 3.
Component system: in this system, static and dynamic systems can be used at the same time.
That is, in addition to the main part of the building as a static system, the necessary electrical and mechanical components and systems are added to the building. 3. 4.
Choosing the right system and designing the complex method: the system suitable for the residence
The entertainment complex is a hybrid system due to the cold and mountainous climate and a large amount of energy demand.
The best location for the building is in the West-
The East of the sun.
Scilicet, the length of the building erected in this direction and the width of the building erected in the South
Since the North direction of the south wall gains the greatest energy in winter, this wall can be protected by the canopy in summer. West-
The summer east wall is located in the sun and should have a lower level.
It is best to rotate the building to the east until the summer sun shines directly to the West .
After placing the building properly in the site, various types of static systems can be used according to the physical application of the complex.
For example, for heating and cooling of residential rooms, they can be placed in part of the building to make the most of the light in the South.
Also consider the basement of this set of equipment and place some applications, such as the swimming pool in the area, to take advantage of the insulation properties of geothermal energy and the Earth, because the temperature of these spaces must always be balanced, and prevent as well as the basement as insulation material upstairs.
In addition, by creating a cooling and heated green space for different parts of the lobby, restaurant, etc. , you can also provide the required energy.
The cases mentioned on static systems provide only a fraction of the complex energy needs.
Therefore, the active solar system must be used to complete the system.
Therefore, photovoltaic cells are used to generate electricity and provide energy.
Photovoltaic cells can be used in different forms of complexity.
They can be designed to blend into buildings or separate them as a small form
A scale solar farm near the unit.
PV can be integrated into many different components within the building housing :--
Solar cells can be integrated into the front of a building to complement or replace traditional landscape or space glass.
Typically, these devices are vertical, reducing access to available solar energy, but a large area of the building can help compensate for reduced power. --
PV can be incorporated into the awning and saw-
Tooth design on the facade of the building.
These increase access to direct daylight while providing additional architectural benefits such as passive lighting. --
The use of photovoltaic in the roof system can be used for Batten and seam metal roofs and traditional 3-
The use of photovoltaic in the skylight system can not only save the use of photovoltaic, but also achieve exciting design functions.
To design the system in an integrated way, it can be designed to integrate with a roof, wall, or awning, but in a cold climate, because theroof is flat, also due to the fact that the best way to be passive is to combine the design with the roof to get the best form of sunlight and to prevent sunlight from penetrating into the building, it\'s like the roof insulation and.
When static and dynamic solar systems are designed in coordination with each other, the performance is optimal.
Each city and region adjusts the placement direction and method of the solar panel angle and tilt differently, because the solar energy received at different locations is different, and the solar radiation in different parts of the region depends on the latitude, therefore, the inclination of the solar panel, the location of the receiving radiation and the latitude of the assessment, and the area of rainfall, can be considered.
For example, for the big friars with geographical coordinates (18, 46)
Eastern Longitude and (04, 38)
The north latitude and approximate height starting from the Greenway line (1348)to (1561)
Meters above sea level and the average number of solar radiation (3. 8 to 4. 5)
KWhper square meter per day, the favorable direction of the panel can be determined, this direction is located in the south of the big Friars, the appropriate slope of the panel is about equal to the position with a certain degree [+ or -]10 tolerance.
This arrangement provides the best energy exchange of the year to reach 95% of the maximum output power .
The PV system can be operated independently or connected to the network.
Individual systems are not connected to the city power network and cannot use the city power in the cloud or at night, so on sunny days and those days, excess energy must be stored, in order to use on time at night and the time required.
Storing energy in the accumulator, development and maintenance costs are high.
When connected to the system of the network, there is no need to store, because they get energy during the day, consume the required electricity, and sell the rest to the power company, and buy the required energy from the company at night and when needed.
In this system, there is no additional cost to prepare and maintain the storage.
Therefore, the type of connection or isolation can be determined based on conditions and cost calculations. 3. 5.
Investigate the level of efficiency of photovoltaic systems in cold climate and mountainous areas in Azerbaijan: designers should understand the impact of climate and environment on column output.
Cold and sunny weather will increase power production, and will reduce array production on hot and cloudy days; --
Reflect the light to the surface on the array (e. g. , snow)
Will increase the array output; --
An array must be designed for potential snowand wind-
Loading conditions; --
An appropriately sloping array will reduce snow cover relatively quickly; and, --
Array in a dry, dusty environment or in a busy industrial or traffic environment (auto, airline)
Pollution will need to be cleaned to reduce efficiency .
Because solar panels are very useful, direct sunlight is not required.
They even work well when they only receive daylight.
This is a misconception that solar panels perform best in fairly warm and sunny summer months, while they lose efficiency at temperatures above 30 degrees.
Therefore, the cooling temperature is more favorable for the performance of the panel.
The panels are designed to maintain their ability at cold temperatures, so snow, cold temperatures and wind do not damage the panels.
In snowfall and cloudy weather, putting snow on the panel reduces panel efficiency, but as long as the snow on the panel is clean, the sun shines on it, the snow sitting on the ground reflects the sun, it will cause the amount of light reaching the panel to multiply, so the efficiency of the panel becomes very high and the energy will be compensated.
The snow on the panels does not hurt them, the sun can pass through a thin layer of snow on the panels, and because of the hot plates that clean them up, the snow piled up above will melt quickly.
Even in the case of heavy snow and high accumulation on the surface plate, it can be cleaned by hand.
Therefore, in the cold weather, the efficiency of the solar panel is more favorable, because the hot weather reduces the power, in the hot weather, in order to improve the quality of the panel, they must be on the back of the panel
Also for cold areas like Azerbaijan, this must take into account that the total energy received from the panel is relevant for the whole year, and therefore, in the days when the panel receives a lot of energy from the sun, is preserved, and use it on days when less energy is received.
In recent years, special panels have been designed for cold weather as vacuum tube panels that are more expensive than traditional panels, but have a better response to cold areas, better performance, up to about 50%.
There are some new panels with a magnifying glass that can add light and absorb more energy.
To avoid reducing the efficiency of panels in summer and high temperatures, panels are not fully connected to the ceiling, they are adjusted to a few inches from the ceiling until the air flows on the back of the ceiling, causes the page to cool and prevents the roof of the heat transfer panel.
An important issue and requirement in the design of photovoltaic systems is that shadows should not be generated on panels, especially during the day (noon)
The full light should reach the panel at 3 hours noon, because the sun is plentiful during these times, so the panel must avoid creating artificial shadows such As: tall buildings and trees, both the building and the surface cover the panels and the panels created by the horizontal line absorb up to 50-
70% more than vertical lines3. 6.
The historical trend of the hotel industry to green development: tourism is one of the largest and most important known industries in the world. It is developing very rapidly and plays an important role in the economy.
The hotel industry is an important part of the tourism industry. If it is not well managed, it will bring great harm to the society and the environment.
Therefore, in the trend of tourism and hospitality to green development, the expected goals can be achieved in the short term.
In 2007, the trend of hotels towards green buildings accelerated. At this time, the number of green hotels in the United States increased. For example, Bulter hotel in 2008, Wiegler hotel was established in 2008.
Ted Sanders is one of the pioneers in the green direction of hotels that began using green building principles and practices in the hospitality industry in 1989.
The reasons why hotels tend to be green are reasonable, such as social responsibility, national laws and economic interests . 3. 7.
Benefits of using a solar system in a complex: in addition to providing clean energy and no air pollution and preventing adequate consumption of fossil fuels, plans to use solar energy and adapt to the climate will result in welfare customers, it will also reduce the energy cost of the complex, so its owner will reduce the cost of accommodation for the guests.
This is another advantage of investing and applying solar panels for hotels over 10 years, dating back to its owners.
Also do this design for the owners of the complex and the area it is in, advertising has great value, because today the world is more about the topic of clean energy, there are many fans;
Therefore, these types of complexes are very important in tourism.
Conclusion: according to the study conducted in this study, it can consider the use of renewable energy sources such as solar energy in the desired residence
Entertainment complex located in cool and mountain climate is the right way to solve the following problems :--
Dealing with environmental pollution crisis-
Prevent the reduction of fossil fuels. --
