Silkworm cocoons are a biological structure and a natural compound that develop over time and responds well to the environmental conditions for silkworms. Understanding the relationships of cocoon structure inspires the creation of composite structures such as low-weight, high-strength nonwoven bio composites. By means of a descriptive-analytical method and logical reasoning, in this study, in addition to introducing the cocoon structure, we try to offer materials as a non-woven bio composite, using sericin cocoon and natural fibers which for various reasons such as being light, non-polluted, abundant, and low-cost can be a suitable alternative to artificial fibers. These materials are recyclable and suitable in terms of stability and energy consumption; therefore, they can be used as thermal and moisture insulation. This function is simulated and analyzed for the hot and dry climate of Kashan city in the outer shell of the building using the Hani Bee energy analysis plugin in the Grasshopper environment. The results show that the proposed non-woven bio composite can help improve, by up to 12.7%, the thermal performance of the building and decrease the movement of heat between the inner and outer space compared to the same building without thermal insulation in its outer shell.

Water crisis and providing water is one most essential problems that humans are facing. There are several ways for water extraction, depending on population and resources. In this simulation, water is extracted by a cooling tower from humid air. Humid air enters the buried pipes with fans. Then the air reaches the cooling tower. Because of the difference in temperature between air and pipes, air temperature decreases. After this process, there is an amount of residual water, extracted from humid air. The extracted water can be used as drinkable water or for agricultural purposes. In this project, we simulate airflow by Ansys Fluent. Then by using air condition relations, combined with the numerical solution, the amount of extracted water can be calculated. In addition, in the first half of the day, because the temperature difference between airflow and pipes’ wall is more than at the end of the day, the amount of extracted water is different throughout the day. We can obtain that in the second half of the day, the airflow temperature is more than the tower’s temperature, so the air is cooling the tower and preparing the system for the next day.

The output power of renewable resources fluctuates because of their random nature, which can negatively affect the grid. This problem can be resolved by installing battery energy storage systems (BESS). On the other hand, with the increasing development of electric vehicles (EVs), the scheduling of their presence in the distribution networks has become very important; because, any unplanned presence of EVs in the smart parking lots (SPLs) and their simultaneous charging may affect the performance of the grid, negatively. An optimum scheduling for charge/discharge actions of EVs can resolve this problem, and reduce the need for high cost BESSs. In this paper, the problem of maximizing the operator profit is formulated as a mixed integer linear programming (MILP) problem considering the constraints on the requested charge level of the EVs and the permissible exchanged power. Then, the problem is optimally solved, in which a scheduling scheme is proposed for charge/discharge actions of the EVs in the SPLs in order to control the power fluctuations. Simulation results on the data of a typical parking lot in Tehran demonstrate that the proposed scheduling can reduce the number of required BESSs significantly, which decreases the high expenses of the BESS purchase and installation.

Nowadays, due to the increasing demand for energy and the problems of non-renewable energies, renewable energies are growing. In a country like Iran with a radiation potential higher than the global average, utilizing solar energy is a priority among other renewable energy sources. In areas affected by the dust phenomenon, one of the main challenges is the performance reduction of photovoltaic solar panels due to dust accumulation. By conducting a comprehensive review of related studies, the present study categorized the properties of dust and how they affect the performance of photovoltaic solar panels. Also, the dust origins in Iran and the frequency of dust phenomena in the country were studied. It was shown that the different physical properties and chemical composition lead to different effects on the performance of photovoltaic solar panels. Therefore, the effect of physical properties (color, temperature, dust accumulation rate, adhesion, concentration, moisture content, specific gravity, and plastic index) and chemical composition (size, charge, shape, material, and distribution of particles) of dust on the performance of photovoltaic solar panels were studied and classified. The present study can be used as a general reference for additional research in this field according to the dominant dust type in the target region.

The performance of a water-ammonia air-cooled absorption chiller cycle is evaluated using a low-temperature source of solar thermal energy in accordance with Tehran's climatic conditions in different working conditions. Energy and exergy analysis of an absorption chiller with computer code written in EES software is performed. Exergy analysis showed that 71% of the exergy loss in the system is related to the generator and 24% is related to the absorber. The results showed that with increasing the generator temperature to a certain temperature, the coefficient of performance increased. The generator temperature of 70 degrees at low absorber temperatures performs better than other generator temperatures. As the generator temperature rises to about 70 ℃ , the exergy efficiency increases, and then the exergy efficiency decreases with increasing temperature. As the temperature of the generator decreases, the circulation ratio increases, and at temperatures below 70 degrees, this increase is seen as exponential and so undesirable that it makes it practically impossible to use the cycle at temperatures below 70 degrees. With the other negative effects seen at temperatures above 80 ℃ to reduce the exergy efficiency, the generator temperature between 70 and 80 ℃ seems appropriate for the proposed absorption cooling system.

Nowadays, the production of alternative fuels to fossil fuels is one of the most noticeable issues in dealing with environmental pollution. With the same approach, biodiesel is using to replace fossil diesel fuel. In general, this article examines four generations of biofuel production from different sources and economic comparisons of their production. In this review study of the previous reports, firstly, according to the approach of localizing alternative fuels, we discuss the introduction of microalgae's types, their reproduction process and environmental applications, production of biogas, bioethanol, and biodiesel. Afterward, in particular, the optimal method of producing biodiesel from microalgae is investigated, and eventually, a comparison has been made between biodiesel produced from microalgae and fossil diesel fuel and the ASTM standard of biodiesel. The results of numerous studies have demonstrated that due to the rapid growth of microalgae, high efficiency, and the low cost of their cultivation and production, it is possible to produce about 5000 to 15000 gallons of biodiesel from each hectare of microalgae cultivation; which makes the production of biodiesel from algae allocate a significant position compared to other sources of biodiesel production.

After the era of the Industrial Revolution and the emergence of the modern age, many environmental hazards have been appeared. All of intellectual developments led humans to interact more with nature and the environment. The emergence of eco-technical, sustainable and green approaches were as a result of these changes and tried to establish more communication between the artificial environment and the natural environment. Among these, the field of architecture and construction has great importance due to the extent of the impact on the environment. In this regard, and in the field of architecture, many efforts were made in different countries of the world, such as the United States, the United Kingdom, etc. Therefore sustainable Assessment systems were designed and used to better control the construction process. In Japan, the CASBEE system is designed for this purpose. This article tries to study the structural features of CASBEE system as one of the most advanced systems for Assessing sustainable buildings with a descriptive-analytical approach with emphasis on studies. The CASBEE Assessment System technically and accurately calculates the environmental assessment of a building and its effects on its surroundings. While it has paid less attention to the social and economic aspects of sustainable development.

Biodiesel is one of the proposed sources to replace fossil fuels. This renewable biofuel is compatible with current infrastructure and internal combustion engine systems. Potential measurement is necessary before manufacturing and industrial projects, and this is even more critical for biodiesel-related projects due to raw material issues. In this research, the potential measurement for the cultivation of oilseeds for biodiesel production in Tehran province has been done with the help of GIS software. The results of this potential measurement show that parts of the western and central regions of Tehran province are suitable for cultivating oilseeds for use in biodiesel production. However, about 90% of the areas of Tehran province are unsuitable for cultivating oilseeds, and its most significant limiting factor is soil texture. More than 50% of the surfaces of Tehran province have an unsuitable soil texture for growing oilseeds. In order to identify the optimal areas for planting oilseeds, the average cost variable of (Cave) per liter of biodiesel is introduced. The results show that the cost of production, transportation, distribution, and supply of raw materials in these areas is cost-effective when the average variable cost is less than 92 thousand rials per liter of biodiesel produced.
