Insulation Tips

When your whole home is insulated, it maintains its temperature much more effectively and efficiently, saving you money while keeping you comfortable.  It helps to keep the external heat away during summers and vice versa during the winters. Home insulation are basically of two different types; reflective insulation material and bulk insulation material.

Choice of insulating material depends on considerations such as –  Cost of insulating material, Area to be covered for insulation, Standard of insulation to be required,  Cost of energy consumed for heating and cooling, Reasonable fire proof, Non-absorbent of moisture, Not liable to undergo deformation, Resistant to attack of small insects.

Important Things To Know About Green Energy

Green energy refers to the use of power that is not only more efficient than fossil fuel but that is friendly to the environment as well. Green energy is generally defined as energy sources that dont pollute and are renewable. There are several categories of green energy. They are anaerobic digestion, wind power, geothermal power, hydropower on a small scale, biomass power, solar power and wave power. Waste incineration can even be a source of green energy. Nuclear power plants claim that they produce green energy as well, though this source is fraught with controversy, as we all know. While nuclear energy may be sustainable, may be considered renewable and does not pollute the atmosphere while it is producing energy, its waste does pollute the biosphere as it is released.

The transport, mining and phases before and after production of nuclear energy does produce and release carbon dioxide and similar destructive greenhouse gases. When we read of green energy, therefore, we rarely see nuclear power included. Those who support nuclear energy say that nuclear waste is not, in fact, released into our earths biosphere during its normal production cycle. They stress as well that the carbon dioxide that nuclear energy production releases is comparable, in terms of each kilowatt hour of electricity, to such sources of green energy as wind power. As an example of the green energy production the average wind turbine, such as the one in Reading England, can produce enough energy daily to be the only energy source for 1000 households.

 

Many countries now offer household and commercial consumers to opt for total use of green energy. They do this one of two ways. Consumers can buy their electricity from a company that only uses renewable green energy technology, or they can buy from their general supplies such as the local utility company who then buys from green energy resources only as much of a supply as consumers pay for. The latter is generally a more cost – efficient way of supplying a home or office with green energy, as the supplier can reap the economic benefits of a mass purchase. Green energy generally costs more per kilowatt hour than standard fossil fuel energy.

Consumers can also purchase green energy certificates, which are alternately referred to as green tags or green certificates. These are available in both Europe and the United States, and are the most convenient method for the average consumer to support green energy. More than 35 million European households and one million American households now buy these green energy certificates. While green energy is a great step in the direction of keeping our environment healthy and our air as pollutant free as possible, it must be noted that no matter what the energy, it will negatively impact the environment to some extent. Every energy source, green or otherwise, requires energy. The production of this energy will create pollution during its manufacture. Green energys impact is minimal, however.

Note on Energy Efficient Homes

Energy has become, in recent years a central topic in many circles. Be it business, industries, offices and even homes the issue nowadays is all about energy efficiency. Homes in particular have garnered interest as areas where energy efficiency can be easily implemented with many benefits. The design, electrical appliances and sources of energy in a home are some of the aspects that are considered and controlled in the construction of power efficient homes. So what do we mean by energy efficiency? In science the term energy efficiency has more complex meanings and definitions which involve power input and output. For the purpose of this article we will use the simple, layman’s definition.

What if you replace your normal windows with special glass windows that do not allow a lot of heat to pass through them? Now during winter less heat escapes from the house through the windows to the outside and in summer less heat comes into the house. The air conditioner is will be rarely on since the house is already comfortable. In this case you have used less energy with the same results. It is important to note that power efficiency is not the same as energy conservation. Reducing the amount of time you spend using your desktop computer is power conservation. Replacing that desktop with the less energy consuming laptop is energy efficiency. The following are some of the areas in which energy efficiency is applied.

Appliances-Modern day appliances use less energy as compared to older appliances. In most energy efficient homes you will find new models of refrigerators, freezers, dishwashers and other electrical equipment. Also making some changes like getting a clothes line instead of using the dryer saves a lot of power.

Design-The building size, shape, color, location and general design plays a big role in energy efficiency. Getting insulated walls, foundations and basement slabs reduces heat loss during cold weather and maintains a cool temperature in the house in summer. The color also matters. Dark colored houses will tend to absorb a lot of heat than light colored one. So if you live in a cold area it is advisable to use a dark color on your house to save on the energy used in air conditioning. Planting trees around your home also helps to control indoors temperature.

Lighting-One of the major energy saving techniques when it comes to lighting is replacement of the traditional incandescent bulbs with the newer energy saving fluorescent light bulbs. Sky lights are also used to save on the energy used in lighting. There is a lot more advanced technology used in construction and design of homes in an attempt to save energy like Optimum Value Engineering, Structural Insulated Panels (SIPs), Insulating Concrete Forms (ICF), Air/Vapor Retarders, Solar Water Heating, Solar Electricity and many more. Energy efficient homes are the center of interest in the energy sector today and with time they will become a necessity rather than a luxury.

Introduction To Home Insulation

Attic insulation is one of the home improvement processes which are done to keep the temperature moderate inside the house. The insulation is done most probably in extreme hot and cold climatic conditions. The purpose of insulation is the same but the types and style of insulation employed is entirely different. Insulation is also done for secondary reasons like pest resistant, noise barrier, energy saver, reduction of utility bills, etc… The below paragraphs shows the type of insulation based on the seasons. The insulation is done either in the hot climatic region or cold climatic region. Insulation in hot climatic areas: In a hot climatic condition, the hot air enters and accumulates into the house through wall, attic, etc… and lets the cool air to pass out. This happens despite using the electronic cooling equipment which in turn increases the usage and shows rapid increase in the utility bill. Insulating the house will prevent the let-out of cool air. As the radiation level is more in hot temperatures, the insulation also serves as the radiation barrier. The types of insulation used in a hot climate are listed below.

Blown-in attic insulation: As the name suggests, the insulation is implemented by blowing the insulation in the wall or roof in high pressure with the special equipments. Blown-in insulation is done in all types of insulation materials like fiberglass, cellulose and rock wool. There are three main type of blown in insulation used, they are loose fill, wall cavity spray and stabilized type. Blown-in cellulose insulation is the eco-friendly process of insulation, as the material is made from the recycled paper. They are cheaper and can easily fill into the small air spaces and this insulation is implemented in the walls, attic floors and small and tiny places.

Rolled-in insulation: Unlike blown-in, this is the flat piece like insulation materials available in layers. The small layer of materials is taken and the space is filled. This comes under the blanket category. The insulation material used in this type is the fiberglass and rock wool. They carry negative effect in filling the small spaces. This type is very expensive and can be handled easily even by the less experienced workers. Rolled-in insulation doesn’t require the special type of equipment for the installation. They can be implemented in walls and flat floors and ceiling which are devoid of gaps and wires.
