Do Whole House Fans Really Work?

Before considering how effective whole house fans are, it is important to clear up some of the confusion that surrounds them. There are 3 main types of ventilation fans used in homes.They are:

           1.    The most common kind of ventilation fan is the exhaust fan that is used to remove odors from bathrooms, kitchens and other parts of a house.
           2.    Attic fans are used to blow warm air out of the attic so that cooler air can be drawn in. Warm air rises to rest on top of cooler air so the attic is where heat collects. By blowing warm air out, the attic is cooled and this, in turn, reduces the temperature in the house itself.

           3.    Whole house fans are also attic mounted but are much larger and more powerful than attic fans. Because of this, the airflow is far greater so air from all parts of the house is sucked up into the attic from where it is blown out. Cooler air is sucked into the home to replace the air that has been removed and this has the effect of significantly cooling the whole house.

The Whole House Fan Advantage

Once the outside temperature has reached a comfortable level, usually in the morning or evening/night, the whole house fan can get to work. Windows need to be opened (at least 1 in each room) and the fan turned on. The warm stale air from indoors is removed and fresh cooler air is brought indoors. Turning on the fan is just a matter of flipping a switch. The main benefits are:

             ·         With a good whole house fan installed, the need for air conditioning is either removed or reduced to a great extent.

                    ·         The coolness is coupled with a flow of fresh air through the home which is healthier and more energizing than the recycled air of air conditioning.
                    ·         Because of the amount of airflow they provide, whole house fans bring down interior temperatures faster than air conditioning does. This is what is known as the reduction in sensible heat – the heat that you feel.

                    ·         There is another type of heat – latent heat. This is the heat that has been absorbed by furniture, furnishings and other items in the house. These continue to radiate heat from a considerable period of time, which works to counter the cooling effect of air conditioning. The airflow from a whole house fan is continually moving through the house and as it flows over items that have retained latent heat, draws that heat out, bringing down the latent heat quickly so that the house stays cool.

Air Conditioning or a Whole House Fan?

A whole house fan can be either a standalone home cooling solution or can be used in conjunction with air conditioning. In both cases, the benefits are that cool fresh healthy air is circulated in the home and also that the electricity savings are significant.Depending on the size, a whole house fan will typically draw about 500 watts of power. An air conditioning unit that can cool a complete house will usually draw about 5,000 watt – 10 times more electricity.

The Benefits of Installing a Whole House Fan

A large number of homeowners think that because they have an efficient air conditioning system installed in their homes, that is all they need. The talk of whole house fans is of those who have cooling problems and need to supplement the air conditioning. That is a fallacy. A whole house fan can work as a standalone unit to cool and ventilate a house but it can also function as a complement to air conditioning, increasing its efficiency, producing faster cooling and lower electricity bills. Here are the facts about whole house fans:

  • A whole house fan is installed in the attic. It draws the hot stale air from the rest of the house to the top of the building and then sends it outside and replaces it with fresh cooler air that is drawn into the home through windows and other ventilation openings.
  • When an air conditioning system starts working, it must first deal with the accumulated heat and stale air in the house before any real cooling can take place. Whole house fans dramatically reduce the time that is required for this and the effects of the air conditioning can be felt much sooner.
  • The reduced load on the air conditioning system means that it does not have to work so hard and so it consumes less power, resulting in lower utility bills.
  • In many cases, the fan is so effective in ventilating and cooling the house that the running of the air conditioning system is significantly reduced or even eliminated altogether.
  •          The stale air that accumulates in the house is unhealthy and often full of germs and pathogens. Whole house fans will quickly expel this stale air and by doing so, make the home a healthier place.
  •         Whole house fans are not just for the summer months. In winter stale air often gets sealed in the house. This air is full of impurities that can be bad for your family’s health. A whole house fan will keep the air indoors clean and fresh, summer or winter.
      Do Not Compromise

     You have one home and it deserves the best. A cheap fan from a company whose antecedents are unknown will never be able to provide your family with the benefits in terms of cooling, ventilation and health benefits that a fan from a world class manufacturer can. In addition, any notional savings will soon be lost as low quality fans consume more power and have a much shorter lifespan, making frequent replacement a common problem. A whole house fan from a reputed manufacturer, installed by an authorized dealer gives you the promise of years of trouble free use and no installation problems.Because of the health and financial benefits they offer, whole house fans are rapidly gaining in popularity as the best way to cool and ventilate a home. Beware of one-size-fits-all fans. To ensure optimum ventilation and power consumption, the fan has to be the right size for the house. Look for a manufacturer that offers a range of fans so that you can get the one that is right for your home.

How to Buy a Daylighting System

With the growing realization of the advantages of installing daylighting systems at home, the number of manufacturers and dealers of this equipment has mushroomed. As in any area where increasing demand results in greater competition, the quality of products available can vary significantly. Knowing how to buy the best daylighting system means you can look forward to many years of trouble free great lighting at the best prices. Here is what to look for when you make your purchase.

 Light Quality

Technology plays a key role in the amount and quality of light that is available. The efficiency of the roof mounted light collectors is what determines how much light is available. The type of reflective material used on the tubes that carry the light indoors is what affects the amount of light that is lost in transportation. The best technology means that the best lighting is available in the home.


Most daylighting systems are relatively simple to install. But issues like water leakage or heating loss can cause all kinds of problems. Buy only products that offer leak proof sealing to ensure water and air tight installation.

Will It Last?

Cheap daylighting systems may appear to be an attractive option, but how long will they last? Besides lower light availability, you could be looking at expensive repairs down the road. Always go with a reputed brand that is known for quality products. It will save you money in the future.

How Adaptable Is It?

A major advantage of daylighting systems is that they can be installed to provide light almost anywhere, even in the most interior part of a home. However, the distance and the type and number of bends in the piping that carries the light can cause serious losses. Use only a system that offers tubing that can take sharp bends and carry light for long distances without loss.


A multi-functions daylighting system makes life easier. Features such as an optional LED lighting system that is integrated into the device to provide light at night reduces the need for having extra light fittings installed for use at night. Dimmers mean that the amount of light that is available can be controlled so that the lighting can match the way the room is being used at any particular time of the day. And ventilation kits can help to keep the air in the room fresh at all times.


You want your home to look its best. Installing a daylighting system where the light fitting sticks out like a sore thumb leaves a scar on the appearance of the house. Look for daylighting systems where the range of fittings is large so that you can install those that go with the look of your home and enhances its beauty.

The Simple Solution

Dealing with all these issues and finding the right solutions can be tough, if not impossible, for the average homeowner. The simplest way to be sure that you are installing the best daylighting system possible for your home is to buy only from a reputed brand. In fact, buying from the brand leader in daylighting systems that is known for setting standards that others try to emulate will ensure that you get the best system that will give you the best light, trouble free performance and great looks.

Sunlight and Feng Shui

Every family wants their home to be a place of joy and peace. Over the centuries various practices have been adopted to improve the ambience and energy in the home. In recent times, the ancient Chinese art of Feng Shui has become increasingly popular. In essence, Feng Shui is the art of arranging a home and the belongings in it in a way that creates positive energy. An increasing number of people claim that following the principles of Feng Shui has made their homes happier and improved their lives while others claim that it is all hokum. Whatever you may believe, the concept of filling a home with positive energy appears to be something that everyone would like to do.

Sunlight’s Positive Energy

Feng Shui is all about maintaining the balance of nature – the Ying and Yang. If the energy that surrounds you is positive, you are energized and if it is negative, you are drained. Light surrounds you throughout your waking day and if it is the right kind of light, you will benefit from the positive energy that you receive from it.The key here is the “right kind of light.” According to Feng Shui, sunlight is a very strong source of positive energy and the body and mind both benefit from exposure to it. This belief is supported by modern medical science which accepts the fact that sunlight is a major nutrient and has great medical value in preventing sickness as well and assisting recovery from it.

Unlike our ancestors, we spend most of our lives indoors. The amount of sunlight we are exposed to is restricted to the amount that comes in through windows and skylights – it is rarely enough to give us the sustenance and positive energy we need. In fact, there are usually parts of a home where electric lighting has to be used even during the day. A renowned researcher in the field of light has coined the term malillimination to describe the harmful situation that occurs when we are exposed to inadequate amounts of sunlight and excess amounts of artificial lighting. The wide acceptance of this theory is proven by the fact that the German government has banned the use of certain types of electric lighting during the daytime.

Learn From the Kids

Forget about Feng Shui for a moment. Look at children out playing in the sun. A large part of the happiness they exude is from the positive energy that sunlight gives them. Keep them indoors under artificial light and you will notice that while they will still have fun, the energy will be less and different and the laughter not so exuberant. Sunlight makes a difference to mood and energy.

Bring the Positive into Your Home

Whether or not you believe in Feng Shui, there is no denying that bringing natural sunlight into the home has numerous benefits. The easiest, most efficient and cost effective way to do this is by installing daylighting systems which carry sunlight into even the most interior parts of the home. Contact the dealer of a reputed manufacturer to find out more about the cost, health and other benefits that daylighting systems offer.

Transform Your Home with Daylight

One of the biggest trends in interior design over the past few years has been the growth of the “Green” concept. Being green does not mean just using sustainable resources to create the interiors of a home or office. It means creating spaces that leave minimal carbon footprint on the environment. To most people, this simply means using better insulation to reduce heating and air conditioning requirements. That is a good thing but there is more – reducing the lighting load of a home or office not only saves electricity, it offers a number of health and productivity benefits. In addition, designing an interior around the idea of maximizing the use of natural daylight can give the space a stylish and elegant look that has a positive impact on those who occupy it.

Productivity and Mood Improvement

A person who is happy is said to be in a sunny mood. There is a reason for that – studies show that sunlight is a natural uplifter of mood. Sunlight indoors creates a positive aura that fills a room with positive energy. In the home that means a happy atmosphere. In the workplace, it creates an environment where people are more efficient and productive.

Better Sleep

By giving the body adequate exposure to sunlight during the day, the natural activity/sleep cycle of the metabolism is strengthened. Besides being more energetic during the day, the quality of sleep at night is improved. This has a positive cascading effect on all aspects of health and fitness.

Reduced Energy Use

By increasing the amount of natural light available indoors, the use of electric lighting is reduced which leads to lower utility bills. Another benefit is that studies show that doing any activity that involves the use of the eyes is better done in daylight as the strain on the eyes is reduced.

More Attractive Interiors

Designers and interior decorators are incorporating daylight as an integral part of the planning. Sunlight gives an aura of openness, making an enclosed space feel more open and airy. Additionally, sunlight brings out colors better. The Color Rendering Index (CRI) rates how lamps render color. The best CRI is for natural daylight because it has the full spectrum of colors.

Maximize the Sunlight

Most buildings, whether residential or commercial, have areas where there is not enough natural light or where the movement of the sun causes the room to darken at certain times during the day. Adding windows or skylights, even if possible, is an extremely costly and complicated job. And the problem may still not be resolved. However, by installing daylighting systems, the light that is outdoors can easily be brought indoors. Sunlight can be brought to even the innermost parts of a home or office where electric lights have to be used during the day. Daylighting systems are an elegant, easy to install and extremely efficient and cost-effective way to use daylight to add to the look of a home or commercial space. The best way to learn about all the benefits that these systems offer is to contact the dealer of a leading manufacturer.

The Effects of Indoor Light Pollution

We all need light. Without it we are unable to function and life, as we know it, would be very different. However, too much light, especially artificial light, can be a huge problem. Everyday people are exposed to large amounts of artificial light even during the day from office lighting, computer monitors, TVs and even domestic lights that are put on during the day. This excessive exposure has a name – Indoor Light Pollution. New research shows that the effects of this on the body maybe much worse than was initially thought.

Research Results

Early research showed that inadequate exposure to natural light could affect cognitive abilities. The human brain, like that of most other mammals, is tuned to a day/night cycle and functions at its best when it is exposed to adequate amounts of natural sunlight. The human body is a very flexible organism and is able to adapt to conditions quickly and continue to function at optimum levels. However, if it is placed in conditions that it is not designed for over a long period of time, the effects of the unnatural environment will begin to show. But now there is more cause for worry than the issue of cognitive ability.

Researchers at the Leiden University Medical Center in the Netherlands studied the health of rats that were exposed to excessive artificial light. Their health, over a period of some months,was compared to another group that was exposed to much less artificial light. The results showed that the rats that had more artificial light exposure had less muscle tone than the other group and also showed signs of the early stages of osteoporosis. The rats exposed to artificial light also became fatter and had indications of weakened immune systems.There were also signs of muscle atrophy and reduced motor performance.

The Way Out

Luckily, it appears that the effects of this indoor light pollution are reversible. When the rats in the study group were returned to normal levels of artificial light exposure, their health returned to the pre-study levels after a few weeks.

The modern city dweller lives an indoor life, often lit by artificial light. Even at home, many houses require electric light to be used during the day because not enough natural light is able to enter. The use of daylighting systems will go a long way in reducing the dependence of artificial light during the day and allow for the human metabolism to function in a more natural light environment.

A Healthy Home

Daylighting systems use light capture devices and special tubing to carry sunlight through walls and ceilings to even the most interior parts of a building. They are easy to install and once in place, have no operating cost. In fact, the availability of natural light indoors means that the use of electric lighting can be reduced which will help to bring down utility bills. Great lighting, better health and economy all in one package is something that no homeowner should ignore. To find out more, contact a daylighting systems dealer.

Children Need Sunlight

Every parent knows that adequate exposure to sunlight is an essential component of a child’s health and growth. The sun is a vital source of Vitamin D which is a critical component of not just building strong bones, but overall good health and physical development. Unfortunately, children in this country are becoming increasingly deprived of sunlight and the effects on their health are increasing at an alarming rate. This is not scaremongering. 

A National Health and Nutrition Examination Survey conducted by the Centers for Disease Control (CDC) found that “50 percent of children aged 1 to 5 years old, and 70 percent of children between the ages of 6 and 11, are deficient or insufficient in vitamin D.” The Hopkins Children’s Center says that “60 percent of children may have sub optimal levels of vitamin D. Prolonged and untreated vitamin D deficiency can affect multiple organs and functions, including bone growth and density, metabolism, heart and immunity, but it rarely causes overt symptoms and often goes unnoticed. 

Vitamin D deficiency in childhood can cause skeletal deformities, brittle bones, frequent fractures and lead to premature osteoporosis in later life. However emerging evidence suggests that vitamin D is involved in far more than bone health. Recent studies have found a link between low vitamin D levels and some cancers, heart disease, suppressed immunity and even premature death.”

The Cause
Today’s children spend too much time indoors. Hours spent in classrooms, at home doing homework, watching TV or on the computer leave little time for spending time outdoors in the sun. While parents do encourage their children to be outdoors, there is often just not enough time. In addition, there are now issues of the health effects of pollution and excessive sun exposure that often cause parents to be unsure about how much time to allow their children to spend time outside and also the reason for the increasing use of sunscreen among kids. Sunscreen may protect against skin cancer and excessive tanning, but it also blocks off Vitamin D.

Sunlight Indoors?

The simplest solution to the problem is to ensure that children are in natural daylight even when they are indoors. Windows may allow for fresh air to enter a house, but the amount of light that enters is limited and affected by the time of day and the season. Installing daylighting systems in a home is a simple and effective way to bring sunlight inside. Roof-mounted natural light collectors capture sunlight and this is carried to every part of the house by using high tech tubing. Even those parts of the house that have access to very light natural light through windows and skylights can now be filled with sunlight. The children, and the adults, in the home will now have access to natural sunlight in a safe form that protects their skin and leaves any pollution outside.

Daylighting – Simple and Economical

Modern state-of-the-art daylighting systems can be installed in just a few hours and are both elegant to look at and long-lasting. Another huge advantage is that once installed they run for free, resulting in major savings on the amount of electricity that is used for lighting during the day.
