Indoor Sky is dedicated to developing products that optimize both occupant comfort and energy performance through daylight harvesting for applications in education, healthcare, retail and commercial offices.
Variable environments require variable solutions – the Dayliter Shade is an off-the-shelf, economical solution to the control of daylight and glare while remaining fully configurable.
The heart of the system is a fabric lightshelf, or combination of lightshelves, designed to extend the daylight zone deeper into a building. Fully operable, the Dayliter Shade may be deployed according to the ultimate variable; sunlight. Blocking direct, heat-laden sun while, at the same time, offering near perfect glare-free daylight!
The Dayliter lightshelf is a totally configurable element mounted directly to the main roller shade assembly. The white or light-colored fabric bounces daylight onto the ceiling and deep into the room even when the main shade is closed to block direct sunlight.
Where the clerestory height is too tall for a single lightshelf configuration, a “stacked" array of lightshelves is available.
The lightshelves diffuse the daylight to dramatically reduce glare by lowering luminance ratios, a critical factor when dealing with computer screens. Other light reflecting products that utilize polished surfaces, such as upside-down venetian blinds, create bright patches of light that increase glare.
A variety of fabrics are available for maximum view/visibility, daylight dimming and full black-out applications and in a wide range of standard colors. We recommend 3% transparency for general use, but will supply from blackout to 10% to meet your design and daylighting goals.
Standard Dayliter Shades feature Alkenz fabric from Rollease. Alkenz SunShadow solar screen fabrics provide outward visibility while controlling glare, protecting from UV fading and improving energy efficiency.
Although we use Alkenz as standard, the shades are available with any fabric that you choose. Mermet and Phifer both offer PVC-free fabrics as high quality and environmentally friendly alternatives.
For decades researchers have proven the benefit of daylight and effective daylight management to human development and wellbeing.
From scholastic improvement to better health, students in classrooms employing good daylighting techniques demonstrated superior performance in standardized testing, physical and mental development. Teachers prefer classrooms where they have control of daylight, feeling it significantly improves their overall disposition.
In healthcare daylight is shown to improve healing times and significantly impact patient outcomes. In commercial offices the reduction in glare can lead to greater productivity through reduction in eye strain leading to fewer errors. In retail environments good daylighting is shown to boost sales.
In a study of 3 elementary schools and 2,000 classrooms in the western United States (CA, CO & WA) students with the most daylighting in their classrooms progressed 20% faster in math and 26% faster in reading. Similar studies have shown that good (diffused) daylight can help reduce eyestrain and migraine headaches through control of luminance ratios. It has also been shown to reduce the frequency of tooth cavities. Views to nature and good daylight facilitate a student's cognitive and intellectual development, imagination and creativity.
A University of Florida study demonstrated that the use of lightshelves reduced the use of electric lighting by as much as 46%.
A study in Alberta, Canada, over a two-year period demonstrated that daylighting allowed for the heating, ventilation, and air conditioning (HVAC) system to be downsized significantly, as well as the number of electric lights, reducing energy consumption through reduced lighting loads. It also reduced the noise levels in both the classrooms and library, thus further enhancing the learning environment.
In a study conducted in daylit schools in North Carolina, investments in daylighting could be paid back within three to nine years.
Conventional window shades cost more than you think!
A 1990 study found that the best teachers in the country (winners of State Teachers of the Year awards) emphasized their ability to control classroom temperature as central to the performance of both teachers and students. Teachers believe that thermal comfort effects both teaching quality and student achievement. Unfortunately the control of thermal comfort so often means sacrificing daylight!
In offices, and other facilities where computers are used, glare is a major issue as it reflects on every computer screen making work very difficult. Lightshelves are proven to reduce glare by lowering luminance ratios.
Daylight impacts human health and performance by controlling the body’s circadian system, affecting mood and perception, and by enabling critical chemical reactions in the body. By controlling the body’s circadian system, light impacts outcomes in healthcare settings by reducing depression among patients, decreasing length of stay in hospitals, improving sleep and circadian rhythm, lessening agitation among dementia patients, easing pain, and improving adjustment to night-shift work among staff.
Daylight is a highly cost-effective means of reducing the energy for electrical lighting and cooling. But architectural education often reduces the aspect of daylight to eye-catching effects on facades and scarcely discusses its potential effects – not just on cost, but on health, well-being and energy.
Indoor Sky's Dayliter Shades were recently featured in the Daylighting & Sun Control section of the July/August issue of SNAP Magazine. This unique bi-monthly magazine published by McGraw-Hill Construction is devoted entirely to covering the most cutting-edge, environmentally friendly building products.
The Indoor Sky team recently supported Susquehanna Health and the Muncy Valley Hospital by sponsoring a hole and playing in their annual golf tournament at Wynding Brook Golf Club in Milton, PA. One memeber of the team even won the coveted "Most Creative Hailer of the Beverage Cart" award with his dancing skills. Proceeds from the tournament will go toward the renovation and expansion of the Muncy Valley Hospital Emergency Department.
