The modern building designed in 1958 by Oscar Niemeyer is an architectural heritage, limiting interventions on facades. The electric  lighting control and automation system optimizes light integration and reduces energy use, while improving user satisfaction. The building makes good use of daylight, thanks to the laminar shape; most offices are located in east façade to prevent glare and overheating.
 

Four types of LED lighting with high-resolution, luminaire-level controls and automated roller shades were evaluated in a 3700 m2 Living Laboratory in New York City. The innovative systems delivered significant lighting energy savings with enhanced indoor environmental quality and comfort.
 

At this office building in the University of Brasilia daylighting is the main lighting source thanks to the building shape, the internal courtyard, and well-designed solar protections. Daylighting and view out with high quality improve user´s satisfaction in the workplaces. Energy use for lighting is high and it could be exploited using electric lighting controls.
 

In this long-term pilot study at Norconsult AS, a horizontal light pipe (HLP) was used to bring daylight to the back part of the office. HLP brought up to 400 lux of natural light to the desk closest to the back part of the office, increased user appreciation of the space, and saved energy.
 

At Slagelse Psychiatric Hospital, they apply a simple strategy in an attempt to improve the well-being of staff and patients. In patient rooms,
daylight and three downlights with a warm colour appearance provide sufficient light during the day. At night, two downlights reduce light levels and colour temperature to help create a calmer atmosphere.
 

In a representative Amazon building daylight use and solar control elements are examined. Occupants are satisfied with the indoor space, despite some changes done to the original design. Computational simulations suggested good daylighting design overall, with little risk for  lare occurrence, as in the intention of the original design.
 

A low-cost manually controlled system, consisting of two motorised roller blinds and six dimmable and tunable led-based luminaires, was installed in a “Living lab” at the Abazia San Lorenzo ad Septimum to investigate the integration of artificial lighting system with shading systems and to guarantee user satisfaction, while energy savings were achieved by simply training the users.
 

A study of integrated lighting at a research and education centre reveals that a highly energyefficient building could be further improved through relatively simple measures. Such measures include shades that automatically return to a fully open state at the end of a day, a manual on-switch for electric lighting and better light sensor positions.
 

At the Fraunhofer IBP in Stuttgart, large scale micro-optical panels were integrated into glazing units and integrated into the upper part of the façade of a lab room. The evaluation of the performance of the lighting conditions and the energy related parameters were compared to a second identical room, with blinds in the upper part of the façade.

At the Fraunhofer IBP in Stuttgart, large scale light-emitting panels were integrated into glazing units and integrated into the upper part of the façade of a lab room. The evaluation of the performance of the lighting conditions and the energy related parameters were compared to a second identical room, with conventional lighting.
 

Monitored, full-scale, outdoor mockups were used to finetune design and control system details then, in the final building, performance was verified with monitored data prior to occupancy.
 

At the DIAL headquarters, an intelligent building was created with the help of modern technology. The aim was to find solutions that satisfy the needs of people, employees and visitors, without staging technical solutions as an end in themselves. Technology and architecture go hand in hand in a holistic concept. The result is an energy-efficient building with the highest standards of comfort and aesthetics.
 

At IKEA Kaarst daylight was brought into the exhibition area. This, combined with clever integration of electric lighting, has improved the shopping experience for customers and left the mark on a bunch of enthusiastic employees.
 

The Spark, a new office building Lund, Sweden, combines abundant daylight with new LED ceiling panels delivering cooler light in the morning, and warmer dimmed light during the afternoon. The system was appreciated by four office workers. It seemed also to increase their alertness, mostly when access to daylight was limited.
 

A novel, operable shade left a positive impression on office workers by opening up views to the outdoors and increasing daylight and comfort compared to conventional shades. 80% of occupants were satisfied with the dual-zone shades. Cooling and lighting energy consumption were reduced by 20%.
 

Daylight responsive lighting controls, electrical lighting, user responses and the luminous conditions were evaluated in a Green Star and WELL platinum certified office building in Brisbane Australia. Combining smart technologies with POE surveys delivered practical solutions to mitigate issues of glare and improve individual control.
 

In this office building, a lighting retrofit with Human Centric Lighting (HCL) system is provided..The HCL can fully change brightness and colour temperature. Based on ZPLC (Zero Power Line Communications) technology, it takes less than three months to complete the replacement and commissioning, without changing the original power line. After renovation, the luminous environment was greatly improved, while achieving more than 60% energy saving compared to the previous lighting system.

In National Aquatics Center, daylight was brought into the competition area. Combined with highpower LED and intelligent control lighting system, this venue improves the race experience for athletes and meets the requirements for various competition modes in winter and summer.
 

In CABR NZEB office building, the integrated solutions for daylight and electric lighting have improved the luminous environment and achieved
nearly 75% energy-saving rate.

A first study of the dynamic LED lighting installed in a section of the rehabilitation centre allows for comparison with the old fluorescent lighting and suggests that patients and staff experience better sleep under the new system that meets the target values for morning and evening circadian lighting suggested by state-of-the art research.

In the Bartenbach R&D building a high level of daylight integration is realized while maintaining glare and heat protection. In combination with workstation-zoned LED lighting with color temperature and intensity control adapted to the time of day, the occupants experience a lighting environment that provides both visual comfort and biologically activating effects satisfying individual preferences. To exploit the energy effects of integral concepts, the heating and ventilation trades are also controlled in addition to the day light and artificial lighting trades.

A POE assessment was carried out in a Green Star commercial o?ce building in Brisbane Australia. Lighting strategies were evaluated which included observations of user behaviour and surveys. The combination of occupancy sensors, side-lighting and manual blind shades delivered a pragmatic solution for indoor lighting in shared environment, with room to improve energy e?ciency and comfort.

A range of daylight and lighting design strategies has been applied in the IDOM office building. The design is focused on the performance and well being of the workers as well as reduction of the electric lighting. Simultaneously the prevention of solar gains with blinds and a double skin façade has been successfully implemented.
 

Low-emittance windows were replaced with variable-tint, electrochromic windows in forty private offices. 85% of the occupants preferred the electrochromic windows, citing increased view and visual comfort.
 

A series of daylight and electric light strategies were proposed in a care home in Brussels (Belgium) to improve the visual comfort and circadian wellbeing of residents. The strategies were based on 3D simulations evaluating the quality and quantity of luminous exposures over time in several residents’ living spaces.
