Design Philosphy

Perspective as a design activity

Our approach to lighting design is not to propose uniform lighting designs that emphasize brightness using illuminance distribution maps on floors and desks or simple 3D illuminance verification.

We visualize the effects of indoor and outdoor light leakage, interior color, finish, lighting effects, and color temperature,

and use light-related technology and knowledge to consider the effects on people's physiology and psychology, as well as the growth of plants and crops,

and engage in comprehensive lighting design and planning.

In particular, we proceed with design and planning activities with visualization and backing, such as checking fixture efficiency and verifying appropriate illuminance taking into account the daylight rate due to daylight.

- Four design perspectives -

[ Comfort ]

Lighting design that takes into consideration the balance of illuminance between each part and wiring

In general illuminance design, lighting design is done for each part as a whole. Because of this, at the boundaries between each part, excessive illuminance occurs, so the lighting verification design is prepared in a way that suppresses unnecessary brightness while taking into account the function and wiring of each part. By doing so, the lighting environment design considers the right brightness and brightness balance in the right place, and the number of excessive fixtures is suppressed.

[ Reliability ]

Not only lighting designs that utilize knowledge, experience, and skills, but also lighting design proposals that are based on objective facts and evidence such as knowledge documents.

We recommend lighting design proposals that are backed up not only by technical techniques such as architectural lighting, but also by lighting materials such as lighting-related technology, knowledge, and data. In order to meet not only brightness but also lighting needs, we will make proposals based on verification through backing and simulations.

[ Visualization ]

Illuminance and brightness simulation considering lighting effects and visibility

By calculating the effective range rather than the illuminance range of the entire room, the number of fixtures can be reduced, leading to energy savings. In addition, the wattage is reduced, which also reduces the glare of LED fixtures. Taking into consideration the light distribution characteristics of LED fixtures, which are particularly directional, we check the light distribution balance of the entire three-dimensional space and verify and confirm effective fixture placement.

[ Optimality ]

Selecting the most suitable lighting equipment considering performance and cost throughout the lighting industry

We select lighting equipment and light materials using unique lighting fixtures, centering on lighting manufacturers with strong strengths for each business type and purpose. Taking cost into consideration, we are working to create a lighting environment that creates an impressive spatial presentation.

We promote our design and engineering activities through these four perspectives.

Added value created by lighting design

We believe that the added value created through lighting design does not simply brighten a space, but enhances the value of architecture and greenery by providing physical, psychological and sensory benefits to users. The added value provided is not limited to physical convenience, but is wide-ranging and includes aesthetic, psychological, economic and environmental elements. We believe that the synergistic effect of these values will dramatically increase the appeal and utility value of spaces, buildings and greenery brought about by the lighting effects.

①: Reduction of excessive lighting equipment and visual added value

In visual environments, the emphasis is on "maximizing visual effects with the minimum amount of light necessary." Excessive lighting, in particular, can cause glare and unpleasant reflections, increasing visual stress. In addition, it is possible to control the visual environment using indirect lighting and task lighting, and to reduce excessive and unnecessary lighting equipment.

②: Added value to a well-being living environment through lighting effects

Lighting design brings social, environmental, economic and health benefits while incorporating greenery into natural and urban environments. It also brings a lot of value to crop cultivation in terms of production efficiency. The effect of lighting goes beyond simply improving the scenery, and has a wide range of effects on our living environment.

③: Improving asset value through lighting design

Lighting design is one of the elements that greatly impacts the asset value of buildings and spaces. Specifically, it impacts "enhancing the appeal of the space," "improving functionality," "energy savings and cost reduction," "impacting health and well-being," "improving brand image," and "strengthening competitiveness in the real estate market." Lighting design is not just decoration; it increases the asset value of a property by improving the appeal, functionality, energy savings, health, and competitiveness of the space, bringing many benefits to owners and users.

Three types of visualization through lighting verification

In our lighting environment design, we do not use illuminance values based on the luminous flux method, which takes into account the interior reflectance, but rather use a point-by-point method, which is a calculation method that calculates illuminance values at regular intervals.

Through 3D lighting analysis, we visualize the calculated values of the visual environment, including direct artificial and natural light, and reflected light from the interior, and the transmittance of glass, etc., and proceed with the design process while reaching a common understanding.

①: Illuminance and brightness simulation through visualization, including lighting

effects

Through indoor and outdoor lighting environments such as natural light during the day and artificial light at night, light leaking from indoors and outdoors, reflected light from the interior, and transmitted light, we will proceed with a common understanding of the analysis and visualization of illuminance and brightness (sense of brightness) through 3D lighting analysis.

②: Visual environment design that emphasizes visual sensitivity, in addition to natural

lighting as an energy-saving method

We are not only calculating daylight on horizontal surfaces for the purpose of energy conservation, but also creating a lighting environment that takes into account the visual safety and health environment by using daylight, taking into account the closed-off psychological effect caused by the influence of the relative luminosity factor on people staying indoors due to the influence of daylighting.

③: Illuminance design that takes into account the reflective efficiency of the interior,

including color and details

Even as we transition to LED lighting, future lighting methods will require the reduction of glare from lighting fixtures and the effective use of diffused light to ensure illuminance throughout the room. In addition, the reflective efficiency differs depending on the paint color and finish. On top of that, we are proceeding with a lighting environment design that takes into account the colors and details of the interior, both in terms of safety and health, as well as psychological effects, by visualizing illuminance and brightness verification.
