The energy performance of buildings and energy-saving measures have been widely investigated in recent years. However, little attention has been paid to buildings located in rural areas. The aim of this study is to assess the energy performance of two-story residential buildings located in the mountainous village of Palangan in Iran and to evaluate the impact of multiple parameters, namely building orientation, window-to-wall ratio (WWR), glazing type, shading devices, and insulation, on its energy performance. To attain a nearly zero energy building design in rural areas, the building is equipped with photovoltaic modules. The proposed building design is then economically evaluated to ensure its viability. The findings indicate that an energy saving of 29% can be achieved compared to conventional buildings, and over 22 MWh of electricity can be produced on an annual basis. The payback period is assessed at 21.7 years. However, energy subsidies are projected to be eliminated in the near future, which in turn may reduce the payback period.

The relevance of the research topic is that energy-saving is the key element of modern energy development in the country. In Kazakhstan, energy-saving, and improving the energy efficiency of agriculture is currently a priority task that will solve energy, environmental and economic problems. Without a solution to these problems, the country's development will inevitably hold back. The head of state in the field of energy conservation has set a goal to reduce the energy intensity of the gross domestic product by at least 25% by 2020, and annual energy-savings of 3.5% after 2020. Industry in rural areas consumes more than 70 % of all electricity. As part of the comprehensive plan, their energy audit was conducted 50/50 (50 % of the financing is the enterprises' funds, the remaining 50 % is the state budget). As a result of the energy audit, systematic measures were developed to reduce the energy intensity of the industry, including the electric power industry. Large unproductive losses of energy resources are in the private sector, in this connection, since 2019, the energy audit of JSC "Kazakhstan center for modernization and development of housing and communal services (housing and communal services)" is conducted on budget funds in the private sector. Energy conservation is one of the most important and strategic tasks of the country. Rapidly developing production requires additional energy costs. This is confirmed by the annual increase in energy tariffs. In turn, resources are not unlimited, and their irrational consumption will inevitably lead to not only economic but also to an environmental crisis.


Green environment is not only planting of trees . It need not always be to create or invent something new for having a green surroundings and neighborhood. It can also be to measure to be taken to save our neighborhood from pollution. Many of us do not know the impact of using halogen lamps, neon lamps and other high voltage generating lighting system on our environment. These bulbs not only generate more heat in the surroundings where they are used but also consume high electricity. These lights when discarded will produce gases which are more harmful for the environment. They pollute the air by producing argon gas which will cause health issues like cancer, skin diseases. In the present day of nuclear families people are using more electricity and burn more lamps to have lighting in their homes. To give more clarity they are using artificial lighting to make their homes bright. This problem never arouse in the earlier period as the homes constructed were naturally built in such a way more air circulation was there and more ventilation. Homes in earlier days had backyards and more open space for good air circulation and natural lighting. But in the present few decades the culture of cluster homes apartments, multiplex complexes have become more common as people from rural areas are shifting towards urban cities. To accommodate these migrated families it has become a must to go for multiplex complexes and apartments. This is generating more pollution in the environment. In earlier days we never heard the terms of global warming, pollution control measures, Go green concepts. All these concepts have evolved in the last few decades. One of the reason is during increase in number of apartments, nuclear families. In places where one joint family was using a single lamp to complete their day to day activities are now replaced by 2 or 3 families using one light each in each house. So instead of one light we are using 3 or 4 lamps and generating more heat and pollution in our environment. The present study is an attempt to find out the alternative solution of using LED/LCD, iCaTS lamps on the energy saving and cost saving and environment friendly electric usage system

On the May 12, a huge earthquake occurred in Sichuan Province, and causing tremendous damage. There are 5,401,900 housing collapsed and 5,932,500 severely damaged, and the large number of them should be reconstructed urgently. In the planning and redevelopment of housing for rural residents amounted to 3,500,000 units only in Sichuan. The surveying of post-disaster reconstruction by writer indicating, the buildings of residential in Earthquake-stricken villages and towns are constructed in lower standard than those in city. Single-layer and two-story stand-alone home is the main type of the rural traditional housing. The existing housing in rural areas did not take energy-saving into account, and the vast majority of them cannot meet the minimum level of energy-saving. There will be a good opportunity to promote the energy-saving technique in post-disaster reconstruction in rural areas. Based on the command of building energy-saving design, and combined with climate and geographical characteristics in Wenchuan quake-stricken, the outer blinds system proposed in the energy-saving design of the rural residential post-disaster reconstruction. The outer blinds system is one of traditional architecture techniques. The adjustable sun visor can all be found in the Ming and Qing Imperial Palace and the receiving chamber. But at present, the outer blinds system can be little taken into account in the buildings by local architects and designers. The paper based on energy-saving effect, shade materials, and the service life and initial investment; explored the applicability of outer blinds system in rural areas post-disaster housing construction, and put forward solutions and technology roadmap. The results showed that the shade outside technique has such characteristics like low cost, effective and simple. There are strong applicability in the rural residential post-disaster reconstruction. The paper also analyzed the shade outside technical problems in order to provide some references in post-disaster reconstruction.

Over 17% of the world’s population lack access to electricity, the majority being in rural areas of sub-Saharan Africa and South Asia. Microgrid technologies are a promising solution towards rural and remote area electrification; however, ever-increasing electricity demand remains a big challenge leading to pronounced power outages. Demand-side management is an indispensable tool towards addressing the challenges. This paper employs a mathematical model based on incentives and time-of-use rates to simulate daily power usage pattern of residential customers using data collected from an isolated village Ngurdoto solar microgrid, Arusha, Tanzania. Customer responsiveness on the increase in price was evaluated based on the concept of price elasticity of demand. Using two demand response strategies, namely, load shifting (LS) and scheduled load reduction (SLR), the results reveal that LS can achieve up to 4.87% energy-saving, 19.23% cost-saving, and about 31% and 19% peak reduction and power factor improvement, respectively. SLR method resulted in about 19% energy-saving, 49% cost-saving, and 24% power factor improvement. Thus, the results presented in this study may lead to a more efficient and stable system than the current state in developing countries’ utility.
