BACKGROUND

Innovation in buildings
The company is committed to quality, environmental respect and sustainability, which is reflected in its own workplace in Madrid. With this intervention, they went beyond, focusing on users' well-being.
Sustainable architecture
Built in 2010, the office was awarded LEED Platinum certification. It has a lot of natural light through glass walls and uses automated solar protection to avoid glare, as well as daylight sensors for energy savings.

OBJECTIVES

Increase employees' well-being
Adapting to the changing human biological needs throughout the day.
Increase productivity
Optimising lighting to promote sleep at night and alertness during the day.
Comply with WELL Building Standard in lighting
Taking into consideration how people are using the space.

Increased Productivity

Implementing dynamic lighting in our offices has created a flexible and efficient lighting environment. Smooth communication with KUMUX was crucial in ensuring that the system was installed and configured optimally, with lighting dynamic settings tailored to the specific needs of each work area. This system offers remarkable flexibility, allowing for adjustments in both the intensity and tone of the light based on environmental conditions or user preferences. The result is a bright and dynamic workspace, designed to enhance well-being and boost productivity.

DESIGN PROCESS

LIGHTING DESIGN

With the help of KUMUX guidelines as a basis for dynamic lighting, Ximena Rubio chose the most suitable XAL luminaires to meet the well-being lighting standards for the space, considering their light spectrum.

Ximena's lighting design served as the foundation for KUMUX optimisation of the lighting settings throughout the day.

Melanopic Illuminance of 250 lux mEDI at eye level
Tunable spectrum through colour temperature (2700K - 6500K)
High CRI > 80
Low-glare UGR < 16 / 19
DALI control

XAL - MITA

MITA is a testimony to elegant design with maximum efficiency and versatile applications. Special reflectors provide the ideal screen-working light – perfect for offices or meeting rooms.

XAL - BETO

With a size of only 42 x 42 mm, it is capable of subjectively connecting or dividing a well-designed interior space. This attractively designed light is perfect for workstations and offers a lighting solution with a homogeneous appearance.

LIGHTING OPTIMISATION

The KUMUX Platform calculates the optimal lighting configurations tailored to the unique characteristics of the project and the lighting design, taking into account the latest science and standards on lighting for well-being.

Building type: Office
Geolocation: Madrid, Spain
Standards: WELL Building Standard
Spectral characteristics of XAL luminaires
Vertical illuminance: 350-500 lux depending on the space

KUMUX science-based optimisation

The KUMUX Platform simulates the circadian impact of these lighting settings applied to the existing lighting design at different times of the day. Thus, it is possible to predict that the resulting dynamic lighting would meet the WELL Building Standard. Additionally, the KUMUX lighting curves incorporate recommendations from the Lighting Research Center to enhance biological responses, particularly in the afternoon and evening.

Static lighting set at 4000 K and 500 lux could only align with the Lighting Research Center guidelines for a restricted duration each day.

KUMUX allowed optimising the design to adhere to the Lighting Research Center guidelines consistently throughout the day.

LIGHTING AUTOMATION

Using the existing DALI wiring for the new lighting system reduced the changes needed in the electrical installation to include the Inventronics controls:

DALI Pro 2 IoT Controller provides advanced logic for the lighting system and integration with the KUMUX service for dynamic lighting.
Presence and Daylight Sensors activate the lighting areas only when presence is detected and also save energy by regulating the brightness of the luminaries according to daylight contribution.
Inputs Coupler allows using existing conventional switches to enable/disable presence detectors and the KUMUX automation of dynamic lighting.
DALI Pro Control App provides users with an interface to control lighting manually when required in any space.

KUMUX simplified automation

The KUMUX Cloud service automates the previously optimised dynamic lighting settings for each space into the Inventronics control system. By updating the Inventronics lighting profiles daily, KUMUX simplifies the controller configuration.

When the presence sensor activates the lights, the automation adjusts the colour temperature of artificial light to align with employees' biological needs throughout the day and year.

MEASUREMENT & ADJUSTMENT

After the lighting control system commissioning and KUMUX activation, the real circadian impact of light was measured at different times of the day to check that the designed lighting complies with the requirements.

WELL Standard

The WELL Building Standard is based on the parameter mEDI (Melanopic Equivalent Daylight Illuminance) measured at eye level in the vertical plane.
