The SkyVault Series is a groundbreaking line of tubular daylighting devices designed specifically for large volume spaces with high, open ceilings like airports, convention centers, lobbies, warehouses, manufacturing facilities, and retail centers. The core of the new SkyVault Series is the Solatube M74 DS Daylighting System. It captures natural light at the roof level, and transfers it indoors using Spectralight Infinity Tubing, the world’s most reflective material. The base unit provides a 29 in. (74 cm) opening to the sky, allowing more light to enter an area for higher daytime illuminance and / or greater spacing between units with fewer roof penetrations. The SkyVault Series gives building designers a Solatube daylighting solution that delivers maximum output while minimizing impact on the building envelope and significantly reducing installation costs. 

 


Architectural and environmental integration

The use of daylighting for commercial projects can create challenges as well as benefits. In large spaces especially, shifting light patterns and solar heat gain / heat loss can significantly impact utility costs and personnel productivity. That’s why we continually strive to develop trailblazing commercial daylighting systems that deliver predictable light output, offer design flexibility, and provide peace of mind while allowing you to meet your architectural and environmental objectives. Read on to learn more. 

 

Superior transmissibility

Along with delivering the highest quality daylight possible, Solatube Daylighting Systems produce minimal color / spectral shift of light. Known as high Color Temperature Maintenance (CTM), this characteristic ensures consistent color temperature throughput and stable color rendition across the visible light spectrum over the course of the year. Our systems also boast unrivaled Light Transfer Efficiency (LTE). This means they deliver maximum light throughput for greater output and enhanced long-run daylight delivery with minimal seasonal variation. In short, Solatube Daylighting Systems offer the pinnacle of light output, color consistency and quality of light delivery.

Design flexibility

In commercial projects, one daylighting solution does not work for all buildings. Under-standing this, we designed the SkyVault Series to be modular. The core Solatube M74 DS unit readily accepts innovative daylight collection technologies (to be offered in the near future) that can be added to enhance natural light collection and output and / or extend functionality for nighttime use. 

Labor-saving installation

To design a truly superior high output product, we were compelled to find ways to minimize labor and waste. The SkyVault Series features roof and diffuser modules that are pre-assembled to speed installation. Labor is further reduced with a revolutionary Tab-Lock Connection System with Tube Belts that is screwless and eliminates unsightly, labor-intensive seam tape.

We’ve even reduced distribution costs by transporting the SkyVault Series on pallets with its components nested. This results in minimal packaging, allowing you to address USGBC LEED construction waste management requirements. Through design innovations and smarter shipping methods, the Solatube M74 DS reduces labor and waste to save time and money. 

Occupant productivity

When sunlight is allowed to enter a building through Solatube Daylighting Systems, the people occupying it tend to be happier, healthier and more productive. We believe everyone deserves to experience the benefits that bright, beautiful natural lighting has to offer. The sustainable lighting design of our commercial daylighting products enhances occupants’ functionality so they can work and live at the highest levels. 

Focused Delivery

When traveling at shallow angles, daylight tends to get lost in the ceiling region rather than reaching the critical task areas below. The SkyVault Series Amplifier delivers focused light over greater distances by reorienting daylight to strike the Prismatic Diffuser at the most effective angle. As a result, occupants receive an abundance of focused light at the visual task plane with reduced light loss at the ceiling level.

Optical controllability

The SkyVault Series selectively redirects, reflects and delivers the visible spectrum of daylight to large interior spaces. At the same time, it filters out infrared wavelengths to reduce daytime cooling loads. It also prevents harmful ultraviolet light from entering the building, which can damage and fade interiors. The design also reduces glare and minimizes shifting patterns of light for a consistent light distribution pattern.

Year-round temperature control

Maintaining a comfortable interior temperature is a huge challenge with daylighting. The SkyVault Series controls temperature with a pre-assembled insulated (R6) and sealed curb cap that minimizes heat gain / heat loss through the roof opening. Add the dual dome option and improve thermal efficiency even more. Put this all together with Solatube International’s legendary visible light transmission, and you’ve got a daylighting solution that’s second to none.

Affordable sustainability 

Solatube products are engineered to reduce environmental impact while providing energy-efficient lighting that nurtures building occupants. By utilizing sustainable natural daylight, our systems eliminate the need for electric lights during the day as well as the utility needed to generate that power. This minimizes a building’s carbon footprint by reducing environmental CO2 emissions.

From a financial perspective, Solatube Daylighting Systems make sense because they are cost-effective and reduce maintenance costs associated with electrical fixtures. In fact, they often have lower installation costs than other fenestration products. The end result is high-performance, eco-friendly commercial lighting at a price that fits your budget. 

Effortless attainability

Getting a SkyVault Series Daylighting System is effortless because we have experienced distributors all around the globe who have undergone extensive factory training. You can find a Solatube daylighting expert in your area using the locator tool at the top or bottom of this page.

Engineered reliability

We engineer our SkyVault Series tubular daylighting devices for reliability with sealed, pre-assembled dome and diffuser assemblies, self-cleaning domes and UV / IR filtering. The result is a commercial daylighting solution that withstands inclement weather, requires little to no maintenance, and delivers bright, high output daylight to occupants for years to come, giving you ultimate peace of mind.
