Lakewood Mall Retrofit with Quadwall

Los Angeles area mall reduces glare and daily energy expenditure with CPI Daylighting’s Quadwall® panels

Bright spots, dark patches and solar heat gain plagued suburban Los Angeles’ Lakewood Center for decades, causing a rise in the mall’s HVAC costs and energy expenditure. In 2010, the then 60-year-old mall began a 4-phase renovation over the next four years that would replace 42,000  square feet of ageing plexiglass skylight with CPI Daylighting’s Quadwall® panels.

The number one advantage of the Quadwall is that there’s an insulating factor between the outside and the inside, which helps the climate control inside the mall because the right temperature can be maintained using less HVAC, since the renovation, we’ve cut the run time of the AC units by four hours per day!

The skylights were installed 25 years ago when the roof was first put on the once open mall, but had leaked and cracked over time, holding a U-value of .73 when replaced. By contrast, the new CPI Daylighting Quadwall panels have a .22 U-value.

An assembly of two independent translucent insulated panels, the Quadwall system provides indefinite building envelope protection with its Removable Skin Technology (RST) that allows the exterior panel to be removed while still maintaining the integrity of the interior panel. Joined by a mechanically interlocking connection, the dry-glazed Quadwall system eliminates the need for vulnerable adhesives, adding durability, as well as even light distribution with the system’s tight-cell technology. Specified for Lakewood Center in 10 mm ice white matte exterior over 8 mm ice white matte interior, the two panel Quadwall system is an integrated, high-performance daylighting system.

With the Removable Skin Technology, we won’t have the same type of replacement challenges, plus the strength of the panel and the way it’s built makes a big difference too. In the long run, because of zero maintenance and CPI Daylighting’s warranty, costs should be very low on the maintenance side of it.

Scalable, the Quadwall system can be configured with additional insulation, UL-rated Class A or B fire rated roof assembly, sound reduction, dynamic shading, additional structural performance or even military forced entry resistance as well.

Today, visitors to the Lakewood Center enjoy an enhanced shopping experience, as high quality light streams through the new CPI Daylighting Quadwall panels.

I definitely see a difference in the way the interior light looks from the old skylight to the new Quadwall. It’s much brighter without any glare. Now, that’s what we were looking to achieve!

Otterbox Gets New Warehouse Skylights

Otterbox’s new home brings natural daylight into the workplace

Otterbox’s new home brings natural daylight into the workplaceSkylight Specialists was contacted by General Contractor Brinkman Construction. They wanted to bring in Daylighting into a 36,000 sqft warehouse. Their goal was to achieve savings to the lighting costs of such a large indoor space. The placement of the 4’ x 8’ translucent skylights bring in a tremendous amount of light. The dramatic scene shown above illustrates the need for very little electrical illumination.

Bringing natural daylighting into the workplace or schools for that matter achieve better attendance, higher productivity and even health into the structure. Daylighting studies have shown that when you bring in the blue spectrum of natural daylight you make your workers and your students better and healthier people.

How Daylighting Impacts Our Productivity

Increase Your (Or Your Employees) Productivity with Proper Lighting and Temperature

Daylighting has many benefits, and while most companies and studies focus on cost reduction, daylighting can have a more subtle, yet equally important benefit for yourself or your company.

People who work in natural daylight work more effectively, work longer, feel healthier and happier by the end of the day.

 

9386-7901Most people notice the difference between daylight and artificial light (think about working another day in the office, or spending the day outside) but typically don’t equate it to natural lighting.

A recent study by Mirjam Münch (and others) compared the two environments and recorded how performance, sleepiness, and hormonal activity. They studied two groups of people, one worked in natural daylight, the other in artificial lighting for 8 hour periods. Their results:

Subjects felt significantly more alert at the beginning of the evening after the DL (daylight) condition, and they became sleepier at the end of the evening after the AL (artificial light) condition. For cognitive performance we found a significant interaction between light conditions, mental load (2- or 3-back task) and the order of light administration.

They also performed better, especially on more difficult tasks, in daylight than artificial light.

One more important finding is that our cortisol levels drop significantly under artificial or poor lighting conditions. Cortisol controls our stress and energy levels, losing it prematurely means you are more tired and stressed throughout the day.

To put it briefly, spending the day in dim or artificial light makes us sleepy, less productive and stressed. This can be powerful knowledge to have in home and office design. Paying attention to your and your employees rhythms and needs can improve your and their productivity and make the place a more enjoyable environment.

Saving Energy With a Good Daylighting System

Properly designed daylighting systems save energy and costs

Artificial lighting requires large amounts of energy and can represent as much as 50% of the electricity consumption of a building. Artificial lighting also generates a large amount of heat. When a good daylighting system is considered in the design phase the HVAC system can be reduced in size and operational cost will be lower.

Replacing artificial lighting systems with an effective daylighting system can reduce a building’s energy costs by as much as 30% to 70%. It is essential that lighting controls be utilized in a good daylighting system.  If the artificial lights are not turned off when the appropriate light levels are met the daylighting system is probably not saving any money on energy.

There are skylight manufacturers that tie the available daylighting into the lighting controls to always insure correct amounts of light and at the same time manage costs to avoid waste.
