As you are planning your home for natural lighting, why not use the same elements you used for natural lighting for natural ventilation purposes as well.

Each element such as windows, clerestory windows and roof windows can and should be operable. There is minimal cost difference between fixed units and operable ones, so this decision is often an easy one to make.

By doing so, you will be amazed at how effective cross-ventilation can be, how comfortable it is, and how much energy it can save by turing off your air conditioner

Cross Ventilation Tips to Consider:

Here are some tips for cross ventilation:

Cross Ventilation - Chimney Effect:

This is where you tap into the natural physics of rising air. Design cool outdoor air to come in low, through low windows in the space and exit as high as possible.

This can be through use of clerestory windows or roof windows (the operating component of skylights). This will give you natural air-conditioning and you will see significant saving on your electric bill.

The Chimney Effect also allow you get deep penetration of cooling outdoor air into your living spaces and increases the efficiency of they method of ventilation.

Cross Ventilation - Operable Windows:

My first choice is to use the rising hot air to circulate air, as in the chimney effect method mentioned above.

If that is not possible, locate operable windows as far apart from each other in a room or space as possible.

The ideal is at opposite corners of a square room. While this is usually not possible, locate the windows on different walls so the natural air will flow into the space as deeply as possible.

If you only have exterior access on one wall for a room, simply locate the windows as far apart from each other on the wall.

This, of course will give you minimal cross-ventilation and pursuing other options such as a high ventilation source should be investigated.

If you plan on including sliding doors, french doors or single swing doors during the planning phase of your new or remodled home, include them in the planning process for locations complimentary to operable windows.

Also seriously consider doors that will either ventilate or have an insect screen available.

Another option that can be considered are folding doors, such as manufactured by Nanawall, Inc.

Cross Ventilation - Custom Replacement Windows:

Certainly when it comes time to consider replacement windows for your home, check out windows that can contribute to and enhance the cross ventilation of your home.

A few things to look for are:

Windows that vent both high and low to allow for a bit of a chimney effect by themselves. What this means is a multiple or stacked effect window.

Casement windows can allow you to direct wind direction a bit better than awning or double-hung windows.

Awning windows can be cracked open very easily during a rainy day without worry of water infiltration (during a reasonable breeze).

Attic Cross Ventilation

Attic Cross Ventilation:

While not associated with glazing for occupied spaces, cross ventilation for attics is extremely important for your homes health and the health of your family.

If you do not have proper ventilation in your attic, you risk potential, leaking inside walls, mold build-up and dryrot, compromising the structural integrity of your home.
