The Future Build

Lighting Solution for Siemens HQ in Masdar City: A Case Study

Siemens new headquarters building for the Middle East region in Masdar City and the first LEED Platinum certified office building in Abu Dhabi has been designed to optimize its natural environment and carbon efficiency. This allows it to offer a truly sustainable and commercially viable solution aligned with Masdar’s vision for the low carbon city. 

The Siemens Building sets the standard in sustainable engineering, providing a 20,000 sqm Grade A office space. Through its parametric façade design, the building maximises efficiency by building more with less. The façade structure - effectively a box within a box - reduces solar glare and heat gain, at the same time allowing natural light to penetrate the office and communal space. Efficient and flexible 4,500 sqm office floor plates allow occupiers the ability to configure a bespoke space to suit their needs.

Siemens Building - Masdar City

The building is designed to achieve a 46% energy usage reduction compared to ASHRAE 90.1-2007 baseline through various passive and active design features.

Designed by Architects Sheppard Robson, the building is one of the most energy-efficient buildings in the region. Based on energy modeling and simulations, the building's annual energy consumption is 109.5 kWh/sqm which is much lower than Abu Dhabi commercial building business as usual consumption which is 333 kWh/sqm. 

One of the energy efficiency interventions that contributed to the building's high-energy performance is the selection of energy efficient lamps throughout the building. Light-emitting diode 9LED) and florescent lamps are mainly used, achieving an average lighting power density of about 7 W/sqm.

The architecture of the building allows plenty of natural daylight in the offices. The adjustment between natural daylight and artificial light is controlled through daylight and motion sensors. The sensors regulate the light levels throughout the entire building by only adding as much artificial light as actually required. Light switches can only be found in areas without windows to ensure that no energy is wasted. 

Zumtobel Lighting

Zumtobel’s contribution towards the energy performance is over 1200 energy efficient luminaires around the meeting rooms and general areas. Flexible work stations for casual one-on-one meetings are located all around the common areas. The lighting solution illuminating these areas had to be as flexible as the setup itself. SLOT LIGHT II proved as a perfect fit providing the high efficiency and excellent lighting quality. By producing perfect lighting conditions without annoying reflections on screens such as laptops or iPads, SLOT LIGHT II can be arranged freely anywhere in the room regardless of the position of the workstation. The calm pure light lines bring uniformity to the space and act as a seamless design feature.

In a building where mainly daylight is used, why not integrate a luminaire that produces light similar to daylight? MELLOW LIGHT V provides a gentle, glare-free light distribution without any distracting harsh shadows and still offers a well-balanced illumination of work plane, walls and ceilings for a bright, open room atmosphere. The homogeneous illumination with no visible light source makes the luminaire perfect for meeting rooms and social areas such as small cafeterias.

Designed by Sottsass Associati PANOS is particularly restrained, combining light and space to form a minimalist entity. The flexibility of PANOS offers maximum design freedom while illuminating an office. The luminaire supports general illumination around the corridors and offices of the Siemens building.

“With innovative concepts like the Green Building Initiative and the energy efficiency program, Siemens Real Estate optimizes resource allocation while making buildings more energy efficient at the same time. This applies not only for our construction projects but as well for our own offices worldwide. Our Middle East Headquarters are based in Masdar City Abu Dhabi, which is considered one of the most sustainable places on earth. In order to achieve our LEED Platinum certification the building was designed to use 45% less energy than typical buildings. The lighting solution made a significant contribution towards the energy efficiency of the building. The eco+ label and environmental product declaration of the Zumtobel products helped us identifying the right criteria related to energy efficiency, environmental relevance and application quality”, as noted by Harald Waitl, Head of Real Estate for Siemens Middle East.
