Solar Pads installation on the roof of buildings.

Chile is regarded one of the most promising countries for the development and implementation of renewable energy (RES) technologies, mainly due to the country’s geographical position and diversity, which offers an abundance of renewable energy sources (RES). Wave energy and energy of wind. Hydropower energy, Biomass, geothermal Energy, solar energy, wave and wind energy have significant potential for future use. Chile has one of the largest sources of solar energy in the world, according to the International Renewable Energy Agency (IRENA). According to the International Renewable Energy Agency, the Atacama Desert in northern Chile has nearly 356 days a year with clear skies, high solar radiation and low humidity, making it a great place to generate solar power. Thus, incorporating solar energy into the country’s electricity grid could be an important opportunity to contribute to the country’s energy strategy diversification (Johson S. K., 2018).

To improve and to consume the energy the ministry of chile has established a solar pad in the chile. In chile the ministry that works for energy has decided to implant the solar system on the public building roofs to improve the energy consumption for this they had establish a system which is known as a system of public solar, Roofs (Molly, 2020). According to this system the solar pads are implanted on the roof of building the main purpose of this system is that citizens use energy that comes from sun and consume the electric energy that is usually wasted by many people. Installation of solar panels will undoubtedly improve the energy efficiency of your home. The ability to generate electricity from the sun directly, which hits your roof every day, can significantly reduce your dependence on other forms of electricity production, and in some cases even save you from dependence on other forms of electricity. There are even more benefits: solar panels have been proven to keep your roof cool by providing shade during the day, and also to keep you warm at night by helping to keep you warm. Using solar panels, the researchers were able to reduce the heat amount that reaches the ceiling by 38%, making the roof of the building 60 minutes cooler and more comfortable than parts of the roof exposed to direct sunlight. (Cambero, June 2021)

The main goal of PTSP is to facilitate the maturation of the market for solar PV systems for its own use, contributing to the development of new technologies. The budget for this three-year project will be US $ 13 million and it is designed for three years. The surface that collects energy, which is usually a solar system, solar energy is generated by converting the captured energy into heat or electricity, which is known as conversion efficiency. Solar energy can be converted to solar energy in a variety of ways, the most common of which are the following: In addition to the surface that collects energy, which is usually a system of solar panels, solar energy is generated by converting the captured energy. Energy into heat or electricity, known as conversion efficiency

The specific goals of the PTSP are listed below:

1. Government demand for photovoltaic systems to be installed in public buildings, thus stimulating the photovoltaic market.
2. Provide free public access to information on the costs and conditions of photovoltaic projects for own use in Chile, as well as information on how to participate.
3. In accordance with the Distributed Generation Law, evaluate the current norms and procedures for self-consumption photovoltaic systems.
4. Help reduce the cost of electricity in public buildings by saving energy

An open tender has already been announced for the installation of photovoltaic systems in three buildings in Kalama, marking the start of the PTSP implementation. Units with power from 5 to 40 kW are available in chile. Other tendering procedures are currently underway for the following buildings: TELETON institute Santiago (70 kW), GAM (100 kW).

Figure 2 represents the Solar system in public sector Teleton insistent.

Copiapo (92) four projects and seven projects that are parallel, I and II (total 170 kW) (185 kW). In the 2015 edition of the program, the project was launched with the aim of creating the most beautiful products.

Once the new building is completed, it’s time to install solar panels to power it. If desired, the panels can be integrated into the roof structure. Some solar panels can even serve as a real roof in some cases … BIPV, or the construction of integrated solar panels, is the term used to describe this method of installation.

Chile has become the region’s most important solar energy market in recent decades (Nataila, 2019)It is currently building a photovoltaic (PV) solar power plants with a total capacity of 400 megawatts (MW), more than any other country in the region. By comparison, 400 MW is about half the capacity of a typical nuclear power plant. Instead of receiving government subsidies, Chile is building large solar power plants and experimenting with innovative business models. In addition, the country is building a series of solar thermal projects that could pave the way for greater adoption of solar thermal energy in Latin America in the coming years. (Fishburn, 2016)

Figure No 3 shows energy consumption Efficieneny at Chile buildings.

It is believed that high retail electricity tariffs will be an important economic incentive for increased use of solar energy in homes. Rising interest rates creates more economic incentives for consumers to use PV. The main purpose of solar pads on the building is that less the electricity consumption. Retail electricity prices are influenced by many factors such as production costs, transmission and distribution system ancillary cost service, service and margins of profit among others. In addition, the government may impose surcharges and additional taxes in addition to those already levied. (Gustavo Cáceres 1, 31 December 2014 )Given the wide variation in retail electricity tariffs from country to country, the expected return on investment in solar energy varies accordingly. It is closely observed by the solar pad system in the chile that this solar system is effective to save the electricity that is going to day by day expensive and it also gives the roofs of chile buildings a cooling effect that makes the environment cooler than other buildings that has no solar system. It is a source to make the buildings less use air conditioner, air conditioners are a sources of getting health diseases.

Establishment of Double window panel:

Construction of buildings in industries, economic development and financial companies in Chile in 2008 amounted to about 4.73 million square meters. Santiago accounted for 53.2% of the total, Valparaiso – 6.6%. Office buildings in Chile do not have to meet mandatory thermal performance requirements, and most of their design models are imported from industrialized countries, even if some architecture and design strategies, such as double skin, are not suitable in Chile. Santiago’s climate is continental, with high temperatures and solar radiation in the spring and summer months, especially in the mountains. The city is presently between Andes and Coast Cordillera, making it an ideal destination for tourists. (Wallender, 2-29-2021) The maximum average temperature is 29.7 degrees Celsius, and the minimum average temperature is 13 degrees Celsius in the month of warmest is (January).

Figure 4 Shows the Solar radiation at chile mainly Sataigo

Researchers at the Los Alamos National Laboratory are working to create dual solar windows that generate electricity more efficiently and provide sunshade and insulation to the environment. All of this is made possible by a new window architecture that uses two different layers of inexpensive QDs, tuned to absorb different parts of the solar spectrum at different times (Johson, 2019). This approach improves existing PV technology by incorporating highly efficient solar collectors into existing solar panels or as translucent windows in building architectural designs. Insulating glass units that generate double panel window electricity more efficiently while providing brushes and insulation for added benefits. This is all done through a command line window architecture that uses two different layers of cheap tuned quantum dots to absorb different parts of the solar spectrum at different times. These double-glazed windows and more sophisticated fluorescent, solar hubs are a major step forward in reducing the cost of solar energy, as these features can be made from inexpensive and easy-to-process materials such as quantum dots. The one benefit is that it is possible to process high-energy and low-energy photons separately using a technique known as “solar spectral splitting”. Higher energy photons can produce more powerful solar cells and increase the total amount of energy produced (Crook, 2019). In addition, the dots used in the anterior layer have little or no absorption, so this approach also improves photocurrent.

Figure 5 shows the double panel glass window structure.

Insulated glass units usually consist of two glass plates separated by spacers containing trapped gases such as argon and krypton. They are considered a kind of window that saves energy (Doodle, 2017).

Gaskets help maintain the strength of glass windows under external pressures such as wind and rain. The seal prevents gas from leaking between the two layers of glass and ensures that the windows provide an impressive level of insulation to the house.

In Chile all the public buildings use the double glass window because it they are efficient in saving energy and it has many other advantages that cannot be ignored.

As a house with simple windows in the cold season, has probably the problems associated with winter condensation. It happens when water collects in the windows due to the temperature difference between the inside and outside of the house. Single-panel windows, unlike two-panel windows, allow cold to enter your home. When a cold enters a house, all the water vapor in the house turns into water, which freezes due to the low temperatures that enter through the windows. (Nataila, 2019) Double glazing solves this problem by separating the warm inner glazing from the outer glazing.

In addition to being a more effective insulation than replaceable, single-layer glass windows, each insulation glass unit keeps it cold in winter and warm in summer. As it can be imagined, the reinforced insulation is provided by an additional layer of glass. But more importantly, the gas or air trapped between the two layers performs most of the insulating function and slows the heat transfer in both directions of the window. This is especially important when installing thermal windows. So by keeping in view these points and benefits of the double glass window the public sector buildings have implanted this panel in order to save the energy that is electricity as it is seen that many citizens use a heater that has a direct link with gas and sometimes with electricity (Johson, 2019). In order to save the consumption of energy chile use mostly in their building double solar panel windows.

Establishment of green walls.

Rooftop greening is a scaffolding of vertically grown plants using hydroponics mounted on a self-supporting or wall-mounted structure. Also known as a vertical garden. The various names of living green walls include vertical gardens, green walls, living walls, and eco-walls, to name just a few (Bahrami, September 2014).

Figure no 6 shows the living green walls

Green walls are just as good for the environment as plants are. Plants help purify the air. They help reduce noise pollution because they have the ability to reduce noise. By breathing pollutants and exchanging them for clean, fresh, clear oxygen, the amount of carbon monoxide in the air can be reduced, pollutants can be filtered out and improved air quality (Welch, 2019). There is no doubt that green buildings have many environmental, social and economic benefits. The most important advantage of green building is the reduction of energy consumption. Green roofs and green walls are two examples of green building components that are synonymous with green buildings. Both of these green components have similar properties in that they are based on the concept of land cover that is common in the construction industry. Vegetation, known as the photosynthetic environment, is a well-known natural environment. Vegetation is a well-known natural environment involved in the process of photosynthesis, which releases molecular oxygen and removes carbon dioxide from the atmosphere. Many studies have shown that these two environmental factors are effective in reducing energy consumption in buildings. Therefore, the purpose of this study is to investigate and compare the annual energy savings achieved by installing green roofs and green walls in residential areas in Chile and other cities.

Studies show that green walls in chile, not rooftop greens, provide significant annual energy savings. Studies show that green walls that can provide annual power savings for residential buildings of chile a with RM166 are superior to green roofs that can provide annual power savings for RM139 alone.

The studies represent that many traditional dark roof surfaces absorb more than 70% of their solar energy, resulting in a maximum roof temperature of 65-88 degrees Celsius (Yeang, 2006). Rooftop greening helps reduce heat absorption and disrupt the uniformity of these traditional roofs. Rooftop greening is becoming increasingly popular with businesses, house buildings and many cities as an economic way to raise environmental awareness while addressing traditional roof-related challenges. It is recently seen that many really great projects that make extensive use of the insulation and air purification properties of green walls. In the heart of Concepcion, Chile, there is a modern office building surrounded by Bo Bo Hills, which has been in the spotlight these days. Designed by Enrique Braun Arquitectos, the building uses a lot of local materials and is surrounded by a lush façade studded with bougainvillea, jasmine and plumbago auriculata. Construction is scheduled to be completed in 2018. Vegetation is now beginning to grow on the façade of the building and is expected to cover the entire building within two years.

The government of chile conducted a survey on the impact of rooftop greening of the energy consumption of buildings (Rabah Djedjiga, May 2015). There is some scientific evidence to support the idea that the thermal insulation of the added material helps reduce heat penetration in summer and heat dissipation in winter. In summer, the cooling effect of evaporation plants and evaporation of water retained from the soil can be even more beneficial than in winter.

Figure 7 shows the Green walls in chile

Rooftop greening is essential as a natural cooling system and helps reduce the water footprint in electricity and heat production (E. Schettini, 2018). The thermal benefits of summer rooftop greening include reducing the effects of the heat island by lowering the roof temperature and mitigating roof temperature fluctuations during the hottest hours of the day. As a result, the total amount of energy consumed during the day is reduced. Beneficial aspects. In winter, rooftop greening provides insulation and urban aesthetics. Leak management as a low-impact development (LID) technology is becoming more and more common.

In chile A rooftop greening system with a dew and fog collection system consists of the following components:

• A transparent two-layer mesh covered with a hydrophobic material (ZnO, BaSO4, or TiO2).
• Photovoltaic solar panels, dew collector plates (which can generate electricity during the day and water at night).
• Water pipe;
• Medium for growing microorganisms. And • Microbial medium.

Figure 8 shows the development of greenroof on the building top in chile

In chile Buildings and factories gets benefit from the new multifunctional rooftop greening system when used in the following ways:

• It can improve the thermal efficiency of buildings and factories
• It can reduce the water consumption of traditional rooftop greening and at the same time increase the efficiency of reducing noise, water and air pollution.
• In addition to other uses of non-drinking water in buildings and factories, it can provide water for rooftop greening irrigation(Gustavo Cáceres 1, 31 December 2014 ).

The main goals of traditional rooftop greening systems are stormwater management, thermal impact (mitigated by water problems during the dry period), and landscape. Fognet, on the other hand, can protect plants from direct sunlight by improving the thermal performance of new multifunctional rooftop greens, improving storm runoff management, reducing noise and air pollution, and creating areas.

• During the dry period, traditional rooftop irrigation relies on urban water supply (urban water supply system).(Placeholder12) On the contrary, the various calculations for rooftop greening. In contrast, versatile rooftop greening calculations has shown that the use of fog-collecting grids and dew-collecting solar panels that can collect fog / dew / precipitation can reduce the pressure on urban water resources Increase.

There is difference in green walls and green roof, walls as both of them are being used in chile buildings because they help to conserve the energy. Rooftop greening is defined as a traditional flat roof or sloping roof modified by some or all of the following layers or elements: structural support, moisture proofing, insulation, waterproofing, roof drainage layers, root protection. , Synthetic medium-sized plants and drought-tolerant, tolerant plants These rooftop greening layers have been modified or improved to meet the specific requirements of the designer or building owner. Rooftop greening is usually categorized as extended or intense, depending on its size.

A major application of the benefits of rooftop greening to building walls is often referred to as green walls or vertical gardens. In most municipalities, the amount of space available for walls is important, and in many high-density areas, the potential for green walls is even greater than the amount of space available for roofs. Urban development creates an endless source of wall space that is not currently used in downtown urban canyons and other urban canyons. (Gustavo Cáceres 1, 31 December 2014 )

LEED Lights for energy consumption improvement:

As a result of recent events, environmental issues have been ranked first in the list of people of greatest concern. In response, new environmental monitoring and labeling measures have been introduced and new solutions have been developed to limit emissions to the environment. (OCAD, 2014) The situation is exacerbated by the constant demand for energy and the growing demand for natural resources in both developing and developed countries.

Buildings consume 45% and 42% of total US energy consumption, respectively, while the corresponding share of OECD countries is 31%. Due to the high energy consumption of buildings, plans and regulations need to be developed to reduce the energy consumption of these structures. For this reason, many national and international green building certification systems have been developed and are now in widespread use. The Chile Environmental Impact Assessment Act (CREEAM) is the first such certification system in the world and has since been adopted by governments around the world. (Scolfield, 2019)

The Leadership System for Energy and Green Design (LEED) in Chile, developed LEED by the US Green Building Council (USGBC) in 1998, is the most widely used, but there are other systems as well. Others include the Green Standard for Energy and Green Design (G-SEED, South Korea), the Green Star Program (Australia), and the Comprehensive Built Environmental Performance Assessment System (CASBE) (CASBEE, Japan). In addition, buildings such as Passivhaus and Energy Star have some voluntary energy efficiency standards (Jennifer M. Boyd, 2016)

Today, LEED has become the famous certification building system in the world and is used in countries around the world, including Chile. LEED is defined by the US Green Building Council as follows: “LEED (Leadership in Energy and Environmental Design) is the most widely used green building rating system in the world. LEED certification is available for almost all types of construction projects. ” From new indoor construction, operation and maintenance Provides a framework that design teams can use to design green, green, healthy, efficient, and economical buildings. LEED certification is achieved in terms of environmental sustainability. It is a globally recognized symbol. ” As a result of obtaining a certificate, construction projects are associated with additional costs. One of the motivations for researching the actual performance of LEED certified buildings is to gain knowledge of the energy performance of these structures in exchange for a certificate and money for research. (Alejandra Schueftan, 2013)

When it comes to energy savings, LEED has helped improve Chile’s green building certification system.It strives to minimize the negative impact on the environment while maximizing energy efficiency. Furthermore, in addition to many studies demonstrating the benefits of LEED,researchers emphasize that LEED has not led to significant reductions in building energy consumption and will not be able to meet the energy efficiency goals set in the near future.

Therefore, the purpose of this study is to critically examine the scientific literature related to the LEED system, and LEED certification really means energy efficiency, contributes to the reduction of greenhouse gas (GHG) emissions, and contributes to the building environment. Is to decide if you want to benefit from the overall impact (IEA, 2019).

“The United company of Efficiency, a global efficiency, energy initiative, is helping Chile phase out inefficient lamps in the domestic retail market. According to a UN environmental assessment, the country is on lighting Save more than 20% of the electricity used. Save and accumulate $ 480 million annually in 2030. The phasing out of inefficient lighting technology is one of the most cost-effective and time-efficient ways to reduce global carbon emissions and air pollution. Countries and consumers migrating from incandescent light bulbs to LED lighting, one of the most energy-efficient and fast-growing lighting technologies available today, can expect to save at least 75% on energy bills increase (Roshan Mehdizadeh, 2018).

After establishing a partnership with Chile in 2015, United for Efficiency has been working with the country to cut emissions while saving billions of dollars in recoverable energy costs. By switching to more energy efficient LED lighting, United for Efficiency expects to reduce national lighting consumption by 20 percent by 2030 and save $ 480 million per year from 2020 to 2030, according to the organization. The total amount of money saved is estimated to be approximately $ 4.5 billion. (Pino, 2016)

Figure 9 shows the LEEB lights in the chile house building.

However, in addition to creating significant economic savings, switching to LED lighting will help Chile meet its emissions and climate reduction goals. According to the National Contribution (NDC), carbon dioxide emissions by 2030 will be reduced by 30% compared to 2007 levels 1880g. Given the projected economic and population growth trends, electricity consumption is estimated to increase by 6-7 percent annually by 2020. Energy sector reforms and advances can combine emission reductions with economic growth when governments are taking steps to implement national development programs (OEAD, 2018).

According to the Chilean government, the country’s projected energy consumption will be reduced by 20% by 2025 to meet future electricity demand while reducing its reliance on imported energy. By 2020, a quarter of these savings could be realized as part of the overall goal of the UK’s efficiency projects.

In chile a campaign, a colorful website has been created with discount coupons with LEDs, energy efficiency tips and savings calculators. Another component of the program is the “LED Truck,” which travels around the city and sells LED bulbs that are 60% cheaper than traditional retailers. Trucks also have a typical consumer-oriented educational component. Given that Chilean families continue to increase their energy consumption, it is an important target to reach.

Windows for the energy consume improvement

To maximize the benefits of passive solar energy, it is important to understand the general inclination of the sun between winter and summer. Figure 6 shows a typical solar altitude in Santiago (33 degrees in winter and 79 degrees in summer) (partenership, 2018). The house was designed with a 50 cm cornice and a 30 cm overhang on the north window of the north window. These methods protect most of the north wall from direct sunlight in the summer, but ensure that direct sunlight reaches all north-facing windows in the winter. Radiation is not equally strong on the eastern and western façade, and is considered a cornice on the northern façade because it exists only in the early morning and late night when the average temperature is 13 ° C. The south façade is not exposed to direct sunlight during the day (Wang, 2015). Instead, it receives only diffused and reflected sunlight and has less impact on energy consumption than direct sunlight. The gain of photovoltaic in the north-facing windows was 972 kWh / year, while the transmission loss at the same location was 698 kWh / year. This is the importance of window manufacturing for the ventilation purpose in order to less consume the heat (Sargato, 2017).

For the first time in Chile, general city planning and building ordinances establish the thermal standards required for the thermal performance of new home construction. The temperature control of the new home was done in two stages, followed by a transition period. The first stage, completed in 2000, specified the technical properties of the roof complex. In the second step of the process, the 2007 standard was set for the proportions of exterior walls, ventilated floors, and glass surfaces. There is no mention of developing standards of the potential risk of overheating or in the light of changing weather conditions (Zohu, March 2011).

The heating and cooling energy of the structure can be lost by up to 30% through standard windows that can be considered “heat holes”. Poor window quality can have a significant impact on room temperature, especially if there is insufficient or no insulation around the window frame. In winter, the whole area becomes fluid as if the windows were open, which is very annoying. This is why high quality and reliable windows are essential to your entire home or apartment home. In addition, the window type you choose can have a significant impact on your utility bills, and switching to high-performance windows will significantly reduce your monthly heating and cooling costs (Jose G. Cedeno Laurent, 2017).

The term “passive house” or “passive house” refers to the strict energy efficiency standards of buildings developed by the Chile company Passivhaus. Recognized in more than 100 countries, this international standard is often seen as the culmination of truly energy-efficient and sustainable design and most of the chile house are designed like this way. As a result of the voluntary requirements for energy efficiency of passive houses, low energy homes are being built that use less energy to heat and cool indoor spaces (Xinzhen Wang, 2015).

Low-emissivity glass, also known as low-emissivity glass, is used in energy-efficient windows to block sunlight (actually up to 90%), trap heat inside when it’s cold and outside when it’s hot. Reduce energy consumption and these glasses are used in windows of chile houses. In addition, there are several glass options such as color, gas filler, reflective coating and more. Again, these are all used to save on heating and cooling costs (Zaldívar, 2017) (Gustavo Cáceres 1, 31 December 2014 ).

The use of numerous glass plates and gas is two latest innovations in the field of windows introduced. Double and triple glazing increase the amount of UV is blocked. Triple-glazed windows, block up to 97% of UV rays, prevent discoloration of valuables such as fabrics and floors at home and work, and make you comfortable all year round. Another great solution for energy efficient windows is to use krypton gas to fill the gap between glazing units. This further limits heat transfer and improves completely.

The windows in chile are not equipped with glass, suitable covers or spacers. It can act as a heat hole in the house. It is estimated that one-third of the money spent on heating and air conditioning is literally thrown out of the window. With many new energy efficient window technologies introduced each year in chile. Citizens can be confident that they will start saving money as soon as possible, and as a result your home will be more energy efficient.

Figure shows the window and planting outside the chile buildings.

Plants around buildings help to conserve the energy:

Trained experts have found that strategically placed trees can be as successful as other energy-efficient home upgrades, such as waterproof windows and door insulation and installation. .. Wood helps save on heating and cooling costs (James, 2015).

Trees store shade in the warmer months and protect the wind in the colder months to store energy in chile. This reduces the amount of fossil fuel used to generate energy for heating and cooling.

Placing shaded trees around your house can reduce cooling costs by up to 30%. To achieve this effect, you need to plant at least three large trees around the house.

Plan to plant deciduous trees that shed leaves during the winter. These trees provide shade and insulation during the warmer months of the year and allow the sun to penetrate during the colder months of the year by shedding leaves in the fall.According to chile environmental ministry research (Moser, 2011).

The fact that trees actively cool the surrounding air and trap the radiant heat of the sun means that everything in its shade gets colder than anything else in direct sunlight.

The cold winter breeze can be redirected away from the structures surrounding the branches and leaves, especially the evergreens where the branches reach the ground.

Place these trees on the south and west sides of the building to enhance their visual impact.

Shading hard surfaces such as alleys, terraces and sidewalks to reduce the amount of heat absorbed by the landscape (Michael Kuhns, 2018).

Use evergreen plants that hold the leaves and needles all year round in a carefully thought out pattern.

Therefore, it is seen that in the most buildings of chile citizens has planted trees around their home and gardens. Even they use green walls where they planted living green plants because plants are the main source of oxygen and it keeps the environmental friendly for breath and cooling purposes (Alejandra Schueftan, 2013). As trees are machined for cooling the air in the plant world, thanks to the vast shade created by the canopy and the vast amount of leaves that release the water vapor that cools the surrounding air. Water vapor is released by grass, shrubs, and other vegetation that helps cool the air by generating heat.

The Chile’s energy depends on foreign sources, improving energy efficiency has become an important element of the country’s national strategy to meet its growing energy demand. Chile has implemented a number of initiatives to reduce energy efficiency. Chile has developed a national energy efficiency policy aimed at reducing energy consumption by large consumers. Energy efficiency legislation needs to take into account large producers such as mining companies, shopping malls and pulp mills when developing national energy efficiency strategies. Encourage the establishment and implementation of energy management systems in the industrial and mining sectors, the promotion of cogeneration, the incorporation of efficient technology and technical assistance into projects, and the adoption of energy efficiency measures, to name just a few. Create the project “Signs of Energy Efficiency”. The seal is issued and which category it belongs to is determined by the company’s energy management system, the number and type of development projects undertaken, and the rate of reduction in energy consumption (Crook, 2019). It calls on companies looking to save energy and improve efficiency to receive incentives to improve their competitiveness and further reduce greenhouse gas emissions.

The MEPS label must be affixed to the demand side to ensure that the product meets the Minimum Energy Efficiency Standard (MEPS). Assume that this does not adversely affect user satisfaction and product performance, limits product energy consumption, and does not include product energy labels in consumer decision making. Encourage residents to replace inefficient appliances with energy-efficient appliances through efficient housing and street lighting schemes. Guide residents through the transition of better technology and electricity.

Air Conditioners Replacement:

The rapidly increasing number of refrigerators and air conditioners around the world contributes to global warming, absorbs energy and emits greenhouse gases. Tested green freezing technology helps solve problems and also creates business growth opportunity. Customers are not listening to special offers on the products shouted through loudspeakers when shopping in some of Chile’s largest supermarkets, but they care about their food and the planet while shopping. Hydroxyfluorocarbons (HFCs) are emitted to the atmosphere through refrigeration and air conditioning systems in Chile, as in many other parts of the world. They are a class of potent greenhouse gases with significant global warming potential – the most abundant HFCs are 1,430 times more harmful to the climate than carbon dioxide per unit mass – and they are also highly toxic to humans (secretariat, 2019). At the start of 2000 To make matters the energy required for cooling consumes 17% of the world’s electricity, creating a double destructive threat to the environment. This problem is expected to get worse in the future in chile . From 3.6 billion refrigeration units in 2010 to 9.5 billion in 2050, air conditioners are designed to dominate the market. Achieving this growth will require total power capacity in the United States, the European Union, and Japan. Number of air conditioners sold in 2018 have increased significantly, but most of them have been on average 2-3 times less efficient.

For this reason, it is important to combine the phased decommissioning and decommissioning of HFC with energy efficiency programs. In fact, doing both together can avoid long-term global warming up to 1 degree Celsius. Considering the potential benefits and risks of efficient cooling, the Climate and Clean Air Coalition of Chile (CCAC) has developed an efficient cooling initiative. The project aims to raise government awareness of energy efficient technologies, mobilize resources to improve energy efficiency in developing countries, and test refrigerants and alternative technologies (N.Mistry, August 2020).

A new demonstration of eco-friendly refrigeration technology at the jumbo supermarket in Valdivia, southern Chile, was supported by the Ozone Department of the Ministry of the Environment of Chile, with financial support from CCAC and support from the United Nations Development Program. The demonstration was supported by CCAC and the United Nations Development Program in 2017. The system known as CO2 transfer, freezing not only avoids the use of HFC, but also uses 20% less energy.

Pierre Zechetto, CEO of technology provider Portan, said: “You can make wise financial decisions, get a high return on investment, and get truly eco-friendly technology.” In my opinion, hype is rare. It comes from the facts-it’s like having a cheap car that runs out of gas and doesn’t pollute the environment-you do it every day, I can’t find it.

Energy consumption for space cooling increases faster than any other energy service in the building. Electricity in the world (IEA, 2018). Real estate. China is the world leader in the registration of housing units in the domestic market.

Combining increased frequency of high temperature events with improved living standards will increase the number of people who buy and use air conditioners to maintain air conditioning. Power consumption is increasing rapidly in temperature-controlled countries, especially during the summer months. In the central countries of the world, there are many days when the average temperature is very high, and as a result, the need for indoor cooling is increasing. Electricity demand depends on the type of appliances people want to use and their level of use. Depending on how much citizens buy the device and how much citizens use it, your household makes two decisions that are influenced by common unobservable determinants.

The ministry of energy in chile has recommended new Ac inverter that is being used as a air conditioner because it has following advantages.

The more energy efficient an air conditioning system is, the more sophisticated it provides. Carrier-manufactured air conditioners are equipped with variable-speed compressors that can operate at only 25% capacity while maintaining optimal comfort at home.

You spend less money on your electricity bill. The more energy efficient an air conditioner is, the more energy costs can be saved over the useful life of the system. According to the Chile Department of Energy, installing a new high-efficiency air conditioner could reduce the amount of energy used to cool a home by 20-50%.

Eco-friendly Refrigerants-Air conditioners manufactured after 2010 no longer use environmentally harmful refrigerants. In addition, it is equipped with R410a, which is less harmful to the environment (secretariat, 2019).

Some of the new areas of the Chilean Energy Efficiency Agency (AChEE) may also fall into this category, such as a special funding program for public building renovations (known as the Public Building Energy Efficiency Program or PEEEP). There is sex. While these initiatives are commendable, it should be noted that some US countries and jurisdictions do not cover the full range of energy efficiency services provided to energy end users.
