Health Benefits of VELUX Skylights

There are many considerations to be made when incorporating skylights into your home’s design. There are some as simple as where to locate the skylight to maximize the most natural light during the day, and some as complex as to which u-factor and solar heat gain coefficient ratings would be the most energy efficient in the climate you live. But have you ever considered the impact a skylight would have on your health and well-being?

The importance of daylight to many living organisms is paramount. Daylight is responsible for regulating many biological systems that allow us to function properly. It impacts our production of Vitamin D (which is important for calcium absorption), regulation of our circadian biological clocks, and even its impact on gene expression.

According to the U.S. Environmental Protection Agency, most Americans spend approximately 90% of their time indoors! Being indoors for such a lengthy period of time exposes our bodies to a higher concentration of pollutants; about 2 to 5 times more than if we were standing right outside of our home or office. In fact:

In addition to pollutant sources, the rate at which air exchanges with the outdoors is an important factor in determining indoor air pollutant concentrations. The air exchange rate is affected by the design, construction, and operating parameters of buildings and is ultimately a function of these three factors:

  • Infiltration – air that flows into structures through openings, joints, and cracks in walls, floors, and ceilings and around windows and doors
  • Natural ventilation – air that flows through opened windows and doors
  • Mechanical ventilation – air that is forced indoors or vented outdoors by ventilation devices, such as fans or air handling systems

Outdoor climate and weather conditions combined with occupant behavior can also affect indoor air quality. Weather conditions influence whether building occupants keep windows open or closed and whether they operate air conditioners, humidifiers, or heaters, all of which can impact indoor air quality. Weather also has a large effect on infiltration. Certain climatic conditions can increase the potential for indoor moisture and mold growth if not controlled by adequate ventilation or air conditioning.

A simple and effective solution is to incorporate ventilating skylights into your home’s design. The skylight will allow more natural light to penetrate your home or office, which will provide your body with more daylight to help maintain biological functions. The ventilating option will help to decrease the indoor air pollutants, which can cause allergies, asthma and other respiratory diseases, all the while providing your home with energy efficient air conditioning, or fresh air.

Skylights For Less carries the perfect option for your home and budget. If you reside in a consistently warmer climate where venting your home would be a regular necessity and you’re on a budget, you may prefer the manual venting skylight. If you live in a cooler climate where venting the home may be periodic and seasonal, the electric venting skylight may provide you ventilation with ease. The most sustainable option would be the solar venting skylight which can be programmed to open and close at predetermined times. It also houses a sensor that will close the skylight automatically when it rains, which will be one less thing for you to remember. The solar venting skylight and installation is also eligible for up to a 30% tax credit along with solar powered blinds!
