Building Energy


The composition of building energy consumption. Energy Consumption refers to the buildings (including residential buildings, public buildings, and services) using the process of energy consumption, including heating, air conditioning, hot water, cooking, lighting, household appliances, elevators, ventilation, etc. can consumption. Among them, the heating, air conditioning, ventilation and other energy consumption, total energy consumption of buildings accounts for about 2 / 3.

 China’s building energy efficiency potential. 2010, China’s housing total construction area will reach 51.9 billion m2, of which 17.1 billion city m2. At present, the total area of energy-saving buildings in China is only about 2.3 m2, in the nearly two billion m2 of completed area, only 5 more than 10 million m2 is to save buildings, only about 3%, meaning that 97% is a high energy construction, if the goal of saving 50% of the calculated energy per square meter, 30kg of standard coal each year, the 97% of the high-energy buildings consume about one year more than 58.5 million t of coal, energy-saving potential.

 The definition of energy-saving construction. High comfort, low energy consumption building looks plain, but the internal structure is very delicate, especially in the wall structure, the glass doors and windows, heating methods such as the use of a large number of new technologies. If the external wall, roof and ground to increase 5? 10cm thick insulation; use the middle filled with inert gas barrier and high thermal insulating glass window frame enclosed high thermal resistance; in the window shade installation of facilities in the summer heat stop the “invasion” ; use of natural ventilation systems to minimize the window opportunity for energy saving room to reach the goal of ensuring light and bright, spacious and comfortable, but also reduce energy consumption, lower operating costs result. Ministry of Construction since 1997, has gradually introduced the three energy-saving design standards for residential buildings, respectively, to cold regions of the subtropical region to regulate residential building design, according to these new standards than the old design of new residential housing saving 50%? 65%.

 Non-energy efficient buildings and construction of difference and the benefits to the consumer. Ontology construction cost of energy-saving than the non energy-efficient buildings despite an increase of 8%? 10%, but its energy consumption than non-50% reduction in energy-saving buildings? 65%, and the benefit of up to 50? 70 years.

 On the transformation of non-energy efficient buildings. Among non-energy-saving construction, 35% of the heat distribution from the wall, so energy saving should be the first from the building envelope (walls, doors, windows, roof) to start, such as external wall, roof insulation layer increases, back doors and windows sealed section, filled with inert gas with double glazing, energy-saving effect is obvious. In addition, energy saving lamp lighting, heating, cooling system temperature control terminal, district heating, district cooling using household metering device, while the development and use of solar energy, geothermal and other new energy sources, is also the transformation of non-important energy-saving construction measure.

 Present new energy-efficient building materials and technology. External wall and roof insulation for thermal insulation board, fly ash aerated concrete blocks used for wall insulation, double glazing, new low-power windows and doors and other materials; solar, geothermal and other new energy sources use and energy utilization; use of computers to refrigeration and air conditioning systems and intelligent control; building indoor temperature and humidity control technology; cold heat metering and charging technology and products.

About Geothermal Heat Pumps

Geothermal heat pumps are a way to produce energy that essentially makes use of the power of the sun. While different from traditional solar power, the use of geothermal heat pumps is incredibly energy efficient and it helps you to save significantly on your electricity bills. When you install geothermal in your home, you can use the heat pump to both cool your house and heat your house in one of the most energy efficient ways possible.

How Do Geothermal Heat Pumps Work?

The key to understanding how geothermal heat pumps work is to understand that the soil below the surface of the earth does not change in temperature nearly as drastically as the air does. Underground below the frost line, the temperature maintains a consistent temperature that is far steadier than the air. In the Southeast, this steady temperature maintained below the frost line is around 65 degrees.

When you install a geothermal heat pump, loops are buried approximately fifty to seventy five feet underground, below the frost level, and are kept at this 65-degree temperature. The liquid in the loop circulates through the underground loop system and is moved to the geothermal heat pump. Geothermal heat pumps are then able to convert the liquid energy into energy that heats and cools your home.

Because most people usually keep their house temperature in a range of about 65-73 degrees depending on season and comfort level, the 65 degree liquid only needs to be heated or cooled a small amount in order to achieve the desired temperature for air in your home. This means that significant energy is saved because your heating system does not need to make large temperature adjustments to heat or cool.

Installing a Geothermal System

When a geothermal system is installed, there are three components you will need. A geothermal system is one required component. There are two types of systems available. Depending on your individual needs and space, the system may be water based or a direct exchange geothermal system. Your second component is the earth loop, which is responsible for transferring the heat from the earth to the pump. The final component is the air handler that distributes the warmed or cooled air to the rest of the home. Because the system is a multi-part system, it is important to have a qualified HVAC contractor with knowledge of geothermal heating and cooling install a system that meet your individual requirements.

While there is an up front cost to purchasing the components of the system, there are often tax credits provided by the government to offset the cost and encourage making this energy-efficient choice. Geothermal systems will also eventually pay for themselves by saving energy and reducing your utility bills.

Finding the Right Contractor

Once you have decided to have a geothermal system installed, it’s important that you find a trustworthy contractor to perform the work. Look for someone who:

. Has been working with geothermal systems for a long period of time.

. Has a proven track record of satisfied customers.

. Offers fair pricing.

Do your research before hiring a contractor and you will be much happier with the end result.

Renewable Energy Sources-Clean & Safe Source


At present everybody relies on non-renewable energy such as fossil fuels and they are becoming more expensive. Though, these resources have helped the world’s economy to develop and industrialized for many years. It also made the lives easier and shifted towards a faster life environment. Now the trend is changing as the prices has gone up. Nobody wants to pay an extra price for the fuel, as we have much more cheap, clean renewable energy sources. The burning of fossil fuels causes real damage to the environment. This includes CO2 emissions, oil spillage, acid rain and explosion at a nuclear plant. Thus, it is the time when we move on to the pollution free and clean energy source. Renewable energy comes from the natural sources like sunlight, wind, rain, tides etc that replenished in the normal course. These several energy sources can be applied for use within the infrastructure. With the increase in the latest and greatest technological advancements, the systems are becoming more efficient. They are environmentally friendly and free of cost. There uses can be as follows. The sun is the most powerful source of energy. The solar energy can be used for heating purpose, lighting and cooling homes and other buildings. They can also be used in generating electricity, heating water, and a variety of industrial processes. The solar energy can be used in an exactly flexible manner. Solar panels used in houses and communities to provide electricity. They are also used in large power stations. They provide heat for industrial processes and for supplementing large thermal power stations by using the solar concentrators in large installations. This is an inexhaustible-renewable energy sources and nonpolluting. The wind energy is one of the renewable source of energy. It captured by wind turbines and used to generate electricity. Windmills help in providing electricity. The three bladed windmills use turbines that connected to generators. They produce electricity, and they installed in the large windmill farms in large areas. Water is another renewable energy source that is continuously recharged by evaporation and precipitation cycle. The heat from the sun causes water in the sources to evaporate and form clouds. Then the water falls back to Earth in the form of rain or snow and fall back into rivers and streams that flow back to the ocean. This flowing water can be used to give power to water wheels that drive mechanical processes. They captured by turbines and generators at dams. Thus, the energy of water flowing can be used to produce electricity. Tides are more easily estimated than wind and solar energy. The energy supply from tides is extremely reliable and plentiful. Tidal power generation has to be tied using large power systems as they are available only when the tides move in or out. The heat inside the earth produces steam and hot water that can be used to generate power and produce electricity or for several other applications like heating home and, generate power for industries. Geothermal energy can be taken from deep underground reservoirs either by drilling or from the one closer to the surface.

New Energy Portal is supporting the development and growth of renewable energy sources in all the concerned fields. They work for the enhancement of the present situation of the world that wants a fundamental change in terms of energy usage. Thus, it stimulates everyone to Go Green and prefer renewable energy.

The Main Forms Of Renewable Energy

Since renewable energy can usually be obtained without performing considerable harm to the environment, men and women have already been establishing numerous ways to work with it effectively. Although the use of green energy is perhaps not a recent trend, financial investment within these technologies has grown in recent years as an answer towards rising costs of fossil gasoline in addition to results of international climate modification. Here are the five major types of renewable power sources:

• Wind power – Strong winds can handle working wind turbines that are found in some areas to create electricity. Normally these can be viewed along shorelines, particularly in areas where the wind is particularly strong. Wind energy sources are on a clean power that can be utilized as long as the wind continues to strike.

• liquid energy – powerful currents of liquid will also be effective at creating energy. Places where you will find big waterfalls are at a benefit since waterfall currents are extremely strong and that can assist provide a percentage of a city’s electric requirements. Liquid energy is split into variations. They’re: ocean power, hydroelectric energy, kinetic energy from damless hydro, and hydroelectric energy from micro-hydro systems.

• Solar energy – solar technology is obtained from sunshine. This technology relies on solar power panels that gather sunlight and turn it into voltage that will be then kept in a battery for future use. A small grouping of solar panel systems is called a photovoltaic variety and many property owners are actually installing their arrays yourself to augment or satisfy their energy needs. Solar energy could also be used to power individual things, eg lights and portable generators.

• Biomass energy – This energy sources are produced by professional production facilities that process wood and farming items. It is a normal item through the synthesis of trees as well as other flowers. While carbon dioxide emissions are produced through biomass, extent is lower than that from burning of fossil fuels. In addition, biomass cuts straight back on need to produce new landfills as a lot of waste tend to be eaten into the biomass procedure.

• Geothermal energy – Geothermal is obtained from deep into the Earth’s crust. Radioactive particles in the Earth are constantly decaying, creating an energy we can take advantage of for the very own usage. Whilst it’s not at all times an easy task to utilize this as a type of power, once a geothermal power station is installed and operating it gives a source of clean, trustworthy energy with just minimal effects into environment.

But not most of these technologies have already been employed to their complete potential however, it is anticipated that financial investment in alternate power sources continues to escalation in the impending years. It’s likely a combination of these technologies that can help lead us to a cleaner power future.

Utilizing Solar Energy Products


Solar energy is one of the renewable forms of energy which is in demand nowadays. Solar energy products have proved to be unique electricity generating resource for its ability to generate energy in clean and consistent way. The solar energy is also useful for a clean environment. The shift from non-renewable sources of energy, such as coal, towards the solar energy will contribute in making environment clean.

Many energy products are in use today. These include residential solar, commercial solar, and wholesale solar products. Most of the solar power companies also develop a customized solar panel depending upon the individual’s requirement. Thus it is very important to discuss your need with the company professionals.

What are Solar panels?

Generally, solar panels are installed on the roof facing the sun. Different solar panels are available for residential solar and commercial solar purposes. However, in both these main source i.e. solar panel remains the same. The photovoltaic cells on the solar system harness the energy. Not only solar panels are in demand, solar water heaters are also capturing the market. In these solar thermal systems energy of sun is used to heat the water which is then used for other household and commercial purpose, like heating the pool water. These heaters capture sunlight to heat water for domestic use or for a radiant heating system.

Solar panels consist of photovoltaic cells which are comprised of silicon along with phosphorus and boron. The solar panels are easy to maintain, as such they do not require much maintenance. Only little precautions will help you to keep them safe. It is important to place solar panels where they are safe from shade and debris. This will prevent you to wipe them often due to leaves and snow. Solar hot water collection arrays don’t need much attention either. Only you need to periodically use a window wash brush, biodegradable soap, and water to clean the tubes. These are easy to maintain.

What are benefits of solar energy products?

The solar energy products are a great source of minimizing the utility bills. With solar panels installed on your terrace, you get an alternate source of energy which is non-billable. If on a sunny day larger amount of energy is harnessed than required, you can easily sell this excess energy to the electrical company, thus generating large profits. Installing solar panels also make you eligible to get tax rebate.

The availability of different solar systems causes confusion in mind of users as of which system will suit their needs. This basically depends upon three factors, viz, your daily need of power, availability of other source of energy, and sun rays in your area. The skilled professionals will provide you with customized solar systems that suit your needs.

Solar energy products are one time investments. They serve you for more than 25 years with minimal maintenance cost. These result not only in saving your utility bills but also increasing value of your property and heavy tax rebate.

Bio Diesel Versus Diesel


Bio diesel is a non-petroleum based diesel fuel that consists of propyl, esters, methyl and ethyl. It is made from the transesterification of fat from vegetables or animals oils, which are either blended or used independently. When blended they are mixed with petro- diesel in original cars. This fuel is usually regulated and as an ester but excludes other types of diesel. It is usually distributed to be sold in retail markets. Diesel is a fuel used in most fuel engines, has 7.09 density which translates to 18% more than petrol which has a density of 6.01. Diesel emits 38.6 MJ/I combustion when burnt.

When it comes to bio diesel, it requires earlier phase of ignition to guarantee maximum efficiency. The use of it helps in the preservation of the environment and there is no legal penalty for switching. The production of this is scalable as compared to the production of diesel, local co-operatives, small scale, business have produced this by the use of local means. This has contributed to home economics of most nations.

Bio- diesel can save the environment in many ways. Unlike diesel it uses waste products obtained from the environment such as farming products, they are viewed as by products of a very important pat of vegetation. It helps in the increase of efficiency since fewer natural resources are used to grow these materials. Bio-diesel uses the latest technology for its production and in particular traps and filters thus helping reduce the effects on climate that are come from emissions. Marginal parcels of land are used in the production of bio diesel in third world countries. Nuts that produce oil are usually grown along roads and rail lines. In tropical regions such as Malaysia, palm oil is grown rapidly to meet demand in first world countries. Putting in mind that the source of bio diesel is the sun, the over reliance of diesel is becoming less and less. This is through the process of photosynthesis.

The reduction of greenhouse emissions is reduced by bio diesel same to pollution and biodegradation. The demand of first generation bio fuels is reduced by bio diesel too. The reliance of first generation fuels such a diesel brings about emissions that harm the atmosphere and environment. Diesel comes from one source while bio diesel can come from several sources such as algae. From algae, it is produced through the transesterification of triglyceride oil with monohydric alcohols. It can be used in any engine without any modification but this is not the case with diesel.

Confirmation from scientist states that the emissions from bio diesel are less harmful than diesel fumes. This fuel is stored in a dark, dry and clean environment. Acceptable storage materials include, steel, aluminum, fluorinated polyethylene, fluorinated polypropylene and teflon, brass, copper, lead, zinc and tin. Bio diesel can be used pure or can be mixed with petrol at any ratio. It is safe to use and is highly recommended as compared to diesel that most people are doing away with.
