  مدل‌های کسب و کار، ساختارهای اساسی نحوه ایجاد، عرضه و توسعه و نفوذ شرکت‌ها، به عنوان موتور اقتصاد هر کشور هستند. آنها سرعت رشد اقتصادی و میزان مصرف منابع را تعیین می‌کنند. مدل‌های کسب و کار علاوه بر تعداد و نوع مشاغل موجود، کیفیت و قیمت در بازار، کیفیت جوامع و زندگی را نیز تعیین می‌کنند. (Lindsay Clinton, Ryan Whisnant، 2018)تحقیقات نشان می‌دهد که شیوه‌های جستجو بخش مهمی از فرایند نوآوری است. از تئوری دانش مبتنی بر نوآوری و تکنیک‌های آماری پیشرفته (کوپولا با استنتاج بیزی)، نشان می دهد که شرکت‌های در حال تأسیس بطور عمده در هنگام معرفی مدل‌های جدید کسب و کار، هنگام نوآوری محصولات و فرآیندها به چندین منبع خارجی با جستجوی عمیق وگسترده متکی هستند. این جستجوی عمیق وگسترده خارجی برای نوآوری مدل‌های کسب و کار (BMI) مهم است زیرا در هنگام معرفی مدل‌های جدید تجاری که بیشتر به جای دانش فنی یا ضمنی در تجارت تکیه دارند، این مدل به دنبال کشف دانش در زمینه فعالیت شرکت‌هاست.

  Background and purpose: As the world's population grows and energy resources are limited, all countries face energy problems. The crises that threaten countries and communities are the lack of non-renewable sources of energy (fossil fuels), as well as the increase of environmental pollution caused by excessive consumption of fossil fuels which shows the necessities and importance of using renewable energy resources. The close link between the economic and environmental issues has raised new approaches to the field of international environmental law, one of the most prominent of which is the green economy, and since one of the main goals of the green economy is reducing greenhouse gas emissions, the use of renewable energy sources is a quick way to achieve a green economy. In this regard, the main objective of this study is to review the comparative effect of renewable energy on green economy in two groups of selected countries that produce and consume renewable energy with high and middle income. Methodology: This study is an applied research and inferential research method. The method and tool for collecting information and statistical resources are written documents, electronic information and taking notes. Findings: The results of model estimation in the selected countries with Fixed Effects Method during the period of 2005-2016 showed that the use of renewable energy has a negative and significant effect on carbon dioxide emissions as an indicator of the green economy in the selected countries. Also, the effect of renewable energy on the green economy in the group of selected middle income countries is higher than that of high-income countries. Other results showed that economic growth and openness had a positive and significant impact, human capital, ICT and rule of law had a negative and significant impact on carbon dioxide emissions as an indicator of green economy in the group of selected countries. Discussion and Conclusion: Renewable energies are clean, abundant and reliable and if properly developed, can play a significant role in achieving sustainable development goals as sustainable sources of energy. The main reason for the emphasis on the use of renewable energies, in addition to helping to solve environmental problems and preventing the loss of fossil fuels, is the conservation of natural resources for future generations, which undoubtedly renewable energy, given their simplicity of technology, plays a significant role in the green economy and sustainable economic development.

  Bachground and Objective: Following the oil crisis in the seventies and the rising cost of fossil fuels, the use of renewable energies flourished. Applying of new and renewable energies, especially solar energy, the divine eternal source due to its easy availability and, in recent years more attention has been scientists and students of the energy. A variety of methods exist for the use of clean energy and eternal God, but heating water using solar water heaters, as perhaps is the easiest and most economical method. Method: In this study, environmental and economic feasibility of using solar water heater systems in residential buildings, 6 units (households with 4 or 5 persons) using real data in the environment of Retscreen software has been studied. Findings and Conclusion: Results of this research show that the replacement of gas water heaters with the solar water heaters, the annual savings in natural gas consumption to supply hot water for the entire households is consuming 5,820 cubic meters. And the rate of annual economic savings equals 6402000 rials will be replace the electric water heaters the solar water heaters, electrical energy savings of 22,995 kWh annually and annual economic savings of 120,244,000 Iranian Rials.

  Residential buildings consume a major part of energy, soil and natural materials and play a large role in environmental pollution. Energy consumption in Iran is increasing by 270% in the last 20 years. One of the basic solutions to reduce use of fossil fuels, soil and natural materials is the implementation of green buildings. Green buildings reduce the use of natural sand and soil and are generally replaced by micro-produced waste from various industries and mines. Unfortunately, unlike many countries in world, Iran does not have a native green standard and most investors do not have information about benefits of this type of building. In this research, using opinions of experts in the first stage to identify the advantages and obstacles of the implementation of green buildings and in the second stage, using 6 green standards of the world, a total of 68 items in 5 seasons of site, water, energy, materials and the quality of the indoor environment. It has been identified for the native green standard in Iran. The results of 103 questionnaires indicate that the lack of knowledge about green buildings is the biggest obstacle and the high potential of renewable energy production is introduced as the biggest necessity for the implementation of green buildings. Also, among the total number of green standard items, the optimal performance of energy consumption and the use of renewable energies have been identified as the most influential parameters. Finally, based on artificial intelligence, the total green standard score has been calculated. Manuscript profile
