MEP Engineering designers talk. Environment and Facility Idea Note Vol. 08

Electrical work expands from lighting to data utilization and security

FUKAYA-HANAZONO Premium Outlets®

MEP Engineering designers talk. Environment and Equipment Idea Note TOP

Outlet malls are constantly evolving and require a wide range of electrical equipment. This time, we will introduce "electrical equipment that is not just for shopping but also contributes to the design of the experience of visiting."

Designing a new lively space with light

Unlike conventional outlet malls, the street at FUKAYA-HANAZONO Premium Outlets® has a more open feel due to pillar-less eaves. In order to preserve the spacious impression, the lighting plan focuses light on areas where people gather, such as around store entrances and benches.

The street has a sense of openness, with the eaves supported by the building without pillars and the roof sloped downwards, a design never seen in conventional outlet malls.

On the street side of the building, linear lighting is installed under the eaves (①). The fixtures are designed with a milky white cover to reduce glare and ensure the necessary light at your feet, while pillar lighting (②) that illuminates the pillars between the stores as "stage lighting" and downlights placed high up at the store entrances (③) create a lively impression. For ②, medium-angle spotlights that match the brightness inside the stores create a sense of brightness on the wall, and in front of the store entrance (③), wide-angle downlights create a pool of light that draws people in.

In the center of the street, we created a calm space by placing light at low positions such as indirect lighting on the benches and fixture lighting. By shifting the "center of gravity of the light" from the store side, we were able to create a sharper open space and create a comfortable, seamless space with depth.

Creating a "face" for your facility through lighting planning

The building, which is the first thing you see from the national highway, was used as a sign, and the exterior walls were illuminated with lighting.
The exterior wall, covered with white mesh panels, is illuminated from the inside at night, creating photogenic patterns in various colors that give visitors completely different impressions when they arrive and when they leave. We have created an art wall that will become a new landmark for the area.

The floral pattern is based on the concept of the "flower garden" the facility is located in. Some of the mesh panels were created at 1/1 scale and illuminated to examine how the pattern would look.

In the large roofed plaza, which is also a symbol of the facility, lighting fixtures are installed on the pillars of the large roof. In order to avoid uneven lighting on the illuminated surface and shadows from the pillars from limited positions, the appropriate installation direction and swivel angle were verified in advance using 3D simulations. Different effects can be created depending on the season using full-color LED lighting fixtures. It is an ingenious design that can be enjoyed no matter how many times you visit.

Smooth dimming is achieved with DMX control, which is also used for concert productions. A total of 14 programs are operated, including seven seasonal productions and seven event productions.
(Two points on the right) Using 3D simulation, we adjusted the position and angle of the lighting fixtures to avoid casting shadows.

Diverse electrical equipment work to meet the needs of modern facilities

We have utilized IT technology to improve facility operations since the opening.

■ Understanding parking lot usage

We planned to analyze data on parking lot usage and images from surveillance cameras near the entrances and exits to understand how busy the facility is, appropriately allocate vehicle guides and facility guides, and use the license plates of visiting vehicles for marketing purposes.

(Right) An image analysis camera installed at the entrance to the parking lot.

■ Using various camera equipment and image analysis, we obtain data that will lead to the future

In addition to the image analysis cameras at the parking lot entrance, the surveillance cameras at each entrance will be linked to image analysis software to detect people entering and leaving, making it possible to analyze visitors. We hope that the analysis data will not only help us understand the frequency of use of each entrance, but will also be useful in designing common areas such as restrooms.

■ Security equipment to ensure safety and security at facilities

Security is also important in facilities with a large area and many entrances. If we could determine the number of people remaining on the premises just before closing time based on the difference in the number of people entering and exiting, we could expect to improve the efficiency of management and patrols. We set up security areas using image analysis software and introduced a system that sounds an alarm if it detects human figures outside of business hours, and we were able to reduce the labor required for patrols and strengthen crime prevention using the equipment's technology.

The images from security cameras are linked with image analysis software, allowing the same system to count people during the day and detect intrusions at night.

What should we keep in mind now when designing buildings that will be used for 50 or 100 years, in the future when technologies that are unimaginable today will likely be commonplace? I think the real test of an electrical MEP Engineering 's skill lies in whether the equipment will reach the end of its lifespan without any accidents, and whether people will think, "This was designed with this in mind," when it's time for renewal or expansion in a few decades' time.
