One of the most sought-after features of a home has often been natural light. It increases the size of rooms, the color palette, and the appeal of common areas. But its worth goes way beyond the realm of aesthetics. Homeowners are increasingly looking at daylight as a way to live in a healthier, more green way today.
More and more studies are finding that having access to healthy light can help you sleep better, boost your mood, boost your alertness, and boost general well-being. Increasing daylight inside can reduce reliance on incandescent lighting during the day, reduce energy consumption, and promote a more energy-efficient home at the same time.
The issue is that many of the areas where people rely on the most, such as hallways, bathrooms, laundry rooms, closets, and internal kitchens, frequently receive little to no healthy light. Bringing more sunlight into the home can be particularly hard in Arizona, where homes are often designed to minimize solar heat gain and keep interiors great.
Cylindrical daylighting systems are changing conversation in that regard.
Healthy light benefits both the planet and the people.
Architectural and design professionals have known daylight as one of the best ways to enhance domestic environments for years.
According to the World Green Building Council, having access to healthy daylight increases productivity, increases alertness, and improves well-being. Various studies have shown that normal daytime light exposure promotes better circadian rhythms, better sleep quality, and higher levels of serotonin production, which boosts mood and helps lessen stress.
These similar UV rays can also affect a home’s overall efficiency. Every hour that incandescent lighting is replaced by daylight, households save energy. Increasing the amount of daylight available can help homeowners reduce that demand while creating brighter, more comfortable living spaces, even though lighting typically accounts for roughly 15 % * of home electricity consumption in the United States. The goal for Arizona homeowners isn’t just adding more sunlight. It effectively brings in daylight without causing any additional heat.
Many homeowners today see daylight as a component of making a home that supports both specific wellness and environmental responsibility rather than just as a design feature.
More Than Just a Skylight
Circular daylighting systems offer a unique method for bringing sunlight indoors, despite the popularity of traditional skylights. These systems are designed to capture, transfer, and scattered light in a more controlled manner than they do as a window in the roof.
A modular rooftop dome that captures sunlight all day, including lower-angle light in the morning and evening, is the first step in the process. Advanced visual techniques in some systems help to redirect that light into the tube while reducing the overpowering midday glare.
From there, sunlight enters the home through greatly reflective tubing, which allows for the roof to be flooded with light without compromising the quality of the home. Since the tubing can navigate attic obstacles without making significant structural changes, daylight can enter indoor spaces without the need for artificial lighting throughout the day.
Instead of a severe beam of sunlight, light is dispersed throughout a fixture or diffuser to create soft, yet illumination once it reaches the ceiling. Some systems even provide design options, dimming options, and included nighttime lighting, giving homeowners more control over how daylight appears and how it is used in their space.
The end result is a straightforward, effective way to make dark rooms in homes like hallways, bathrooms, laundry rooms, closets, inside kitchens, and other areas look better.
Amazingly easy installation
Some homeowners assume that a significant remodeling project is required to add more natural light to their home. Traditional skylights frequently involve organizing several trades to coordinate roofing, drywall, painting, and finishing projects, as well as cutting big openings in the roof.
Cylindrical daylighting systems have a unique approach. Installation usually doesn’t require structural changes or substantial interior construction because they only need a small roof opening and are designed to fit between existing rafters. The very indicative tubing can likewise be positioned around attic barriers, allowing light to enter areas that aren’t directly beneath the roof.
Installation of asphalt shingle roofs can be carried out by a qualified installer in about two hours for many homes. Roofs made of slate, metal, and tile may take longer to install because the roofing material, but the procedure is still much less cumbersome than homeowners anticipate.
The end result is a home improvement project that minimizes disruption while maximizing impact. Owners typically get to enjoy brighter interior spaces in a one day without the trouble, expense, or protracted construction schedule that comes with traditional skylight installations.
Designed to produce heat rather than light
One of the biggest concerns for some Arizona homeowners is whether bringing in more natural light even results in more heat.
That is a legitimate concern. Any home improvement that has an impact on thermal performance deserves cautious consideration in a climate where keeping homes cool is a top priority for much of the year.
Modern circular daylighting systems are engineered to maximize obvious daylight while limiting unintended solar heat gain, in contrast to traditional skylights, which operate much like a window in the roof. They use sophisticated optical technology to capture and transfer the visible spectrum of light while reducing many of the thermal energy that causes heat buildup rather than simply allowing sunlight to enter through a large glass opening.
Solatube’s daylighting systems, for instance, use proprietary Spectralight ® Infinity tubing and rooftop optics to effectively diffuse daylight into interior spaces while limiting thermal impact. Additionally, the system prevents faded fabrics, furniture, artwork, and flooring from fading over time by blocking 100 % of UVB and UVC rays, along with 98.5 % of UVA rays.
The end result is beautiful, secure natural light that avoids many of the disadvantages that are typically associated with large skylights for energy-efficient home design. That means having plenty of daylight while maintaining domestic comfort throughout the year for homeowners in Arizona and various hot climates.
Daylighting Has Become An Aspect of Interior Design
Green home products are no longer just supposed to perform properly. Today’s homeowners desire products that enhance both the appearance and function of their living spaces. In consequence, daylighting has evolved from a strictly practical solution to a deliberate design element.
The newest generation of cylindrical daylighting systems reflects that evolution. With the just released Brighten Up® Skylight Series from Solara, homeowners now have more room to customize the natural light to their home’s aesthetic. A modern, minimalist look that practically disappears into the ceiling is achieved with the ThinLineTM Collection, which has a ceiling profile that is up to 70 % thinner than past designs. The ContourTM Collection gives the ceiling fixture more structural depth and dimension, making it a beautiful primary point, for homeowners who want to make more of a design statement.
Additionally, modern systems offer a range of accessories that let homeowners choose how daylight is used throughout their home. It is possible to customize each installation to a room’s unique purpose and visual by including included nighttime lighting, solar-powered daylight dimmers, ventilation kits, and decorative lenses that adjust the warmth or softness of daylight.
The end result is a daylighting solution that improves energy efficiency and gives homeowners more freedom to design stunning and pleasant spaces.
A Brighter Future for Interior Design
Natural light is becoming a more significant part of the conversation as homeowners continue to invest in cleaner, more lasting homes.
Circular daylighting demonstrates that upgrading a home’s performance doesn’t usually require complex technology or extensive renovations. One of the best ways to make the most of one of Arizona’s most vast natural resources, daylight, is to make the most of it, which is a state that is blessed with almost year-round sunshine.
