How the Right Windows Improve Home Ventilation

Today’s homeowners rely on mechanical ventilation created by HVAC (heating, ventilation and air conditioning) systems to regulate indoor airflow, often neglecting natural ventilation through the windows. In today’s post, the roofing contractors at Kroll Construction explain the importance of natural ventilation, as well as its benefits.

How Natural Ventilation Works

Natural ventilation uses airflow created by natural means, which includes wind that’s coming from the outdoors, pressure differences between indoor and outdoors spaces, and air movement created by differences in temperature. Depending on differences in indoor and outdoor conditions, opening a window can create natural ventilation from one or more of the said means.

The Right Windows Can Improve Home Ventilation

Certain window styles are more effective than others when it comes to providing ventilation. The key principle to remember is there has to be two openings in the room, roughly the same size: one window vents stale indoor air, then another pulls fresh air in. This type of passive ventilation is similar to the ridge and soffit ventilation on sloped roofing systems. In rooms that can only fit one window, styles such as sliding and double-hung windows can be opened in such a way that they accommodate two openings.

Advantages of Natural Ventilation

Natural ventilation provides the following benefits:

Reduced Energy Costs — Switching to natural ventilation during fair weather can help reduce your indoor heating and cooling requirements, resulting in energy savings. Quality insect screens can help keep the air free from pollen and other particulates.

Less Strain on Your HVAC System — Using natural ventilation in some of your rooms helps reduce the workload on your HVAC system, which can help reduce strain and prolong its service life.

Improved Indoor Air Quality — Natural ventilation helps flush out indoor air pollutants, including volatile organic compounds (VOCs) that come from various household materials like plastic and paint. A constant supply of fresh air from natural ventilation can help maintain a healthy indoor environment.
