When it comes to climate control for a home, the primary focus is on the heating and cooling systems. These are what keep the occupants of the house comfortable whatever the climate is outside. But that is not all there is to it. The cost of the energy consumed is important as is the way the house contributes to climate change which is no longer “the other guy’s problem.” While the goal of fighting climate change is far too important to ignore, no one should advocate living in a home that is too hot or too cold because of the need to conserve energy. But that goal can be achieved without compromising on indoor comfort.

Attic Ventilation

An attic is, in most homes, a rarely used space filled with things no longer needed but which, for several reasons, cannot be thrown away. Because it’s rarely accessed, it’s dusty and often damp, moldy, and full of cobwebs. Ignoring the attic because no one goes there is normal. Why bother about ventilation for a space that is not used? But the attic plays an important role in indoor climate control and with proper ventilation, it can make a palpable difference in your energy bills, and the health of the occupants and help to protect the structure itself.

A well-ventilated attic will:

• Dissipate the heat that builds up there during the summer months. Hot air rises and this heat collects in the attic space. It will then radiate down to the rest of the house, increasing the air conditioning load and causing the system to use more energy. Keeping the attic well-ventilated will reduce the energy consumption.
• Attics are prone to moisture buildup in all seasons, but especially in winter.  This dampness can result in mold formation, and wood rot and even affect the integrity of the structure. Proper attic ventilation will keep the moisture under control.
• The attic is a part of the house and the stale air that collects there will impact the air quality in the rest of the building. Poor air quality can have serious health implications for those who are exposed to it. The effect may not normally be apparent immediately and the health problems can develop unnoticed. But when the ailments do arise, they could be serious.

Choosing the Right Attic Fan for Energy Efficiency

The best way to ventilate an attic is with the use of attic fans. These fans blow out the stale, warm, dusty, and polluted air out of the attic. It is then replaced by fresh clean air that will keep the space well ventilated. The fresh air is cooler than the air that has been expelled so there is no heat collection in the attic to add to the air conditioning load. The fresh air will also improve the air quality throughout the whole house. And when used in the right way, in winter the fan will blow out moisture without making the interior colder so no additional heat generation is required.

The sustainable way to get this result is to install a solar-powered attic fan that will not add to the utility bills. The 30% federal tax credit makes the cost of buying the fan very attractive.

Solatube is the world leader in solar-powered fan technology and manufacturing. The company has a wide range of solar attic fans to suit all types of houses. There are various accessories to add even more value to this already essential and cost-effective addition to the home. In the San Francisco Bay Area, Sunlight Concepts is the Solatube Premier Dealer. Going to the company website will give you all the information you need about the attic fans, the tax rebate, installation, and more.
