Home Ventilation It is Essential to Comfortable Living

It was this simple when energy was cheap!

The Basic Purpose of Ventilation

Your home needs to exchange the indoor air with outdoor air to reduce indoor pollutants, moisture, and odors. Contaminants such as formaldehyde, volatile organic compounds, and radon can accumulate in poorly-ventilated homes, causing health problems. Excess moisture in a home can generate high humidity levels. High humidity levels can lead to mold growth and structural damage to your home. To ensure adequate-ventilation, a home's living area should turn the air over at a rate of 0.35 air changes per hour or 15 cubic feet per person per minute, whichever is greater.


Natural air movement is the most common method of allowing fresh outdoor air to replace indoor air in a home. It was never really a strategy but a by-product of poorly insulated or air sealed homes. This technique was accepted when energy was cheap but for today’s ever increasing energy bills it is usually not the best Ventilation-strategy. Homes are now built to be properly air sealed for energy efficiency or are being retrofitted by using a home energy audit system designed to cut your energy bill by reducing wasted energy from multiple sources. The Home Energy Audit System will help maximize your Ventilation choice

The audit system will help seal your home by identifying where energy is escaping through air leaks.

The energy saving leaks you will seal up though are actually part of a Natural-Ventilation system. Air leaks are hard on energy-efficiency and make it difficult to regulate moisture which can lead to dangerous mold conditions within the home.

Opening windows and doors will help provide natural-ventilation; however because we now use central heating and cooling systems, most people do not open windows and doors as often as we used to. Tightly sealed and/or built homes may have insufficient natural-ventilation most of the time, while homes with high air infiltration rates may experience high energy costs. Using one of the following ventilation systems can help with your energy efficiency, moisture control and ventilation saving techniques.

If you are going to be building or wish to optimize your air movement capabilities while remaining energy-efficient then one of the following choices should meet your specific needs and budget:

* Spot-Ventilation Provide exhausting of unwanted odors and moisture.

* Exhaust-Ventilation System Force inside air out of a home.

* Supply-Ventilation systems Force outside air into the home.

* Balanced-Ventilation systems Force equal amounts quantities of air into and out of the home.

* Energy Recovery-Ventilation systems Transfer heat from incoming or outgoing air to minimize energy loss. * Energy Ventilation-Controls

Improve air flow quality with energy efficient-ventilation controls.

* Mold Mold elmination can protect your family from serious health issues.

Remember that each of these systems provides a higher level of-Ventilation; however each comes at an additional cost. Choose the one that fits your budget and your overall energy plan. Unless money is not an issue, which if not then choose the highest level of managed air flow and obtain maximum comfort, but do not expect a return on the cost that will pay for the installation and maintenance of these high technology systems.

I recommend you review each of the pages for knowledge, then follow the one that fits your budget, returns the maximum savings, and covers the guidelines you find in the

Home Energy Audits made Simple guide book.
