Green Building Certification

The best light for people and the environment

Technological and societal change as well as perceptible environmental changes explain growing awareness of the importance of environmental protection and using resources in a sustainable manner. This applies equally to companies and individuals. It is especially evident in the field in which we operate. In future it will become increasingly vital to recruit, retain and motivate employees by offering them a working environment that is environmentally sustainable and promotes health. This will result in a corporate culture and identity that can be expressed as a spatial experience, contributes to motivation and improves both performance and a sense of well-being.

LifeCycle Tower ONE
Dornbirn, Austria
Owner: Cree GmbH, Rhomberg Bau, Bregenz (AT)
Architect: Hermann Kaufmann ZT GmbH, Schwarzach (AT)
Electrical consultants: Ingenieurbüro Brugger, Thüringen (AT)
Electrical installations: EGD Dornbirn (AT)
The LifeCycle Tower ONE (LCT ONE) in Dornbirn is the world’s first high-rise building with unencapsulated wood-hybrid construction. Officially opened in November 2012, the building impressively demonstrates the future of urban construction, in which innovative technologies, the latest scientific discoveries and a resource-conserving construction method were implemented masterfully. The absolute novelty of the seven-story building, which was built by Cree GmbH as the owner and a subsidiary of the Rhomberg Group, as well as the architecture studio Hermann Kaufmann: the structural elements are made of wood and are not covered with panels. This means that the unclad wood structure of the wood can be experienced inside the LCT ONE, which not only saves resources, but is also part of the fire prevention concept.

Constructed in a modular design, the modules of the LCT ONE were pre-fabricated in the factory and then installed at the construction site, which cuts the construction time by 50% compared with conventional building methods, as well as eliminating sources of errors and ensuring a high level of quality and a reliable cost calculation. In addition, resources are used optimally throughout the entire life cycle of the building to increase energy efficiency and significantly improve the CO2 balance. The LCT ONE sets new standards with respect to sustainability and quality and requires maximum performance on the part of everyone involved.

Zumtobel developed an innovative lighting solution for the LCT ONE for maximum light convenience, reduced energy costs and increased efficiency. Besides ultra-modern office lighting, the light control system LUXMATE LITENET was used throughout the building, combining such complex functions as daylight-based lighting management, control of blinds, presence monitoring, integration of emergency light and pre-defined room profiles in a central and user-friendly unit. Optimal utilisation of daylight, in combination with a total of 112 presence sensors, saves up to 75% of the energy needed for lighting.

“More convenience with less energy” is the motto of the architect Dietmar Eberle for the new six-story building “2226” in the Austrian state of Vorarlberg. The name of the building “2226” refers to the temperature spectrum between 22 and 26 degrees Celsius, which is perceived as pleasant by most people around the world. Thanks to an ingenious system consisting of traditional and modern construction methods, this temperature is maintained constantly in the building – without the use of heating or air conditioning. Instead, Dietmar Eberle relies on the optimal utilisation of daylight, high ceilings and large room depths, effective air circulation and solid walls.

With the aid of innovative software it is also possible to take into account the weather conditions and the number of people present in the building. For this revolutionary architecture project Zumtobel developed a suitable lighting concept that fulfils the architect’s high standards of efficiency, design and multi-functionality.

With an area of nearly 2,500 square metres the office building houses Eberle’s architecture studio “be baumschlager eberle”, as well as other offices, a cafeteria and two famous galleries. The light solution is optimally adapted to the different lighting requirements. The decorative LINARIA luminaire provides for general lighting and ideal light conditions for orientation of the residents and visitors throughout the building. Optimal illumination of the office workplaces is ensured by functional and aesthetic standing luminaires. LED spots of the PANOS INFINITY series deliver very high-quality light for homogeneous general illumination of the traffic areas on the office floor.

Environmental certificate: LEED® Platinum

The new headquarters of the Lauterach-based i+R Group (formerly i+R Schertler-Alge) with its long-standing tradition is considered a showcase project for sustainable building. In October 2013, it ob-tained LEED Platinum and is now the first corporate building in Germany, Austria and Switzerland featuring this certification - and the only one so far. The highest level of LEED green building certification was awarded in the category “New Construction & Major Renovations”. Zumtobel made an essential contribution to implementing the clients' ambitious targets by providing an integrated lighting solution which scored not only in terms of efficiency, but also on account of its flexibility and user comfort.

Intelligent use of daylight in the entire building
The use of daylight plays a vital role in the entire building. Although one aim is to increase efficiency, the main goal is to create perfect working conditions for the staff, explains i+R Managing Director Reinhard Schertler: “For our new i+R headquarters, our top priority was to provide our staff with the best possible ambience. An innovative artificial lighting concept that maximises the use of daylight and thus has a positive impact on our employees' well-being was therefore of utmost importance to us.” A daylight-based control system ensures a perfect combination of daylight and artificial lighting and creates optimum lighting conditions for the staff. Changes in lighting intensity are detected by sensors in the rooms and are automatically balanced. The resulting slow increase or decrease of the lighting level is hardly perceivable to the human eye. Despite the high degree of automation, the lighting solution leaves plenty of room for individual preferences, for all staff members can adjust lighting intensity levels, incident sunlight and temperature according to their personal needs.
Using this energy-saving lighting solution largely based on LED and further supported by presence detectors, the i+R Group was able to cut lighting-related energy consumption by up to 70 percent. In collaboration with the lighting designers of the Bartenbach Lighting Laboratory, Zumtobel managed to develop a lighting solution that provides a high degree of flexibility based on cutting-edge technology. Thus, it meets not only the specific needs of the i+R Group and complies with the high standards placed on LEED Platinum certified buildings, but is also sufficiently compatible and adjustable to fulfil the highest requirements in terms of sustainability and comfort in the long term.

Transparency thanks to environmental product declarations (EPD)
Zumtobel is the first company in the lighting industry to introduce environmental product declarations in compliance with the international ISO 14025 and EN 15804 standards. These so-called EPDs doc-ument the environmental impact of a product throughout its life cycle, for instance in terms of CO2 balance, recycling percentage, material composition or recyclability. In particular when it comes to building certification standards such as LEED, EPDs ensure the necessary transparency and are an essential component of the certification process.
In addition, Zumtobel supports its partners and customers during the building certification process by providing in-house experts for green building. Thanks to their comprehensive know-how, they are able to give valuable advice regarding the development of a sustainable lighting solution, in particular with respect to the different certification processes.

Zumtobel's lighting solution in Vodafone's Ivrea (Italy) branch passed its trials with flying colours. The world's second-largest telecommunications provider is now able to depend on Zumtobel’s quality and experience at its new company headquarters in Milan.

Intelligent use of daylight and efficient lighting contribute to building certification processes
The Vodafone Village consists of three linked buildings covering an area of over 67,000 m², which now boast an all-embracing lighting solution. This solution stands out thanks to its energy efficiency and minimal maintenance costs; it also meets high standards in terms of aesthetics, lighting quality and safety.
Vodafone's headquarters obtained certification according to LEED standards (LEED® 2009 ID+C: Commercial Interiors) and qualified for Silver (52/110 possible points). The building complex is at present the largest LEED-certified building in Italy.
In the “Energy and Atmosphere” category, automated lighting control makes an essential contribution to saving energy (approx. -25%). At the same time, systems for reducing energy consumption inside the building allow for further energy savings of up to 70%.

In order to enhance the staff members' sense of well-being, measures involving the “indoor climate” category have been planned and implemented as well: inside the complex, strategies to ensure high air quality have been applied, such as the installation of CO2 sensors for the densely occupied areas and an increase in the level of air exchange. Finally, the use of construction materials with low emissions of VOC (Volatile Organic Compounds) helps to create an extremely comfortable and healthy atmosphere in these working environments.

Environmental certificate: Climate House
“Everything for the Mountains” is the slogan of Salewa, one of the European market leaders in technical alpine clothing. Even the location of the new corporate headquarters reflects this position: the building designed by Milan-based architects' studios Cino Zucchi Architetti and Park Associati is located in Bolzano at the foot of the “pale mountains”, as the Dolomites are often called because of the colour of their rocks.

Everything under one roof
This extraordinarily shaped building accommodates a variety of functions under one roof:

  • Office and administrative premises for approximately 160 staff members
  • Storage facilities for logistics
  • Largest climbing gym in Italy for up to 250 climbers
  • Fitness room for staff members
  • Day nursery
  • Public assembly room

The individual takes centre stage
The design focused on the individual – above all the staff members. The South Tyrolean model company wants to set an example of an active lifestyle – this is especially important for a mountaineering expert. The building also boasts an integral energy and lighting concept that was certified according to the acclaimed South Tyrolean “Climate House” concept; some parts of the building even achieved the highest level of certification – Gold. As to building materials, care was taken to reduce transport routes, and hence the building's carbon footprint, as much as possible. 90 percent of the suppliers are located in the immediate vicinity. The solar panels on the building produce more energy than it needs. In addition, technologies for heat recovery, heating and cooling the building with additional controllable surface temperature adjustment resulted in potential reductions of 330tonnes of CO2 per year. This amazing value is achieved also thanks to a two-layer glass façade mounted in front of the load-bearing concrete elements for the ceiling and the pillars, which serves as back-ventilated thermal protection with sunscreen glazing on a steel structure.

SPAR has set an example with its new shop concept. In 2010, the first two climate-protection supermarkets in Austria opened almost at the same time (in Murau and Vienna).
For these supermarkets, Zumtobel developed a uniform lighting concept based on LED luminaires only. In combination with other innovative structural measures, the branches will save 50% of energy and up to 80 t of CO2.

Around 35 SPAR and EUROSPAR stores in Austria alone have already been upgraded in line with this new concept in a consistent effort to pursue sustainability as a design objective.

The role of lighting
Alongside heating and cooling systems, lighting accounts for a significant proportion of energy consumption.
LEDs are characterised by their long service life. Good thermal management reduces maintenance effort and hence costs. In the case of emergency luminaires, the client benefits from their low installed load.
25% of the energy required for lighting was saved by using LEDs. This result is confirmed by ongoing assessments carried out by SPAR.

The climate-protection supermarkets in Murau and Vienna were gold certified by the Austrian Association for Sustainable Real Estate Management (ÖGNI).

Interview with Gerald Geiger
Head of “Construction / Energy / Technology” at SPAR Austria
In 2009, the first SPAR climate protection supermarket was opened in Graz, followed by the second-generation supermarkets in Murau and Vienna one year later. As of today, as many as 35 (SPAR and EUROSPAR) branches throughout Austria have been implemented using the new shop concept. As the lighting system is one of the major power eaters besides cooling and heating, Spar relies on both a sustainable LED-only lighting solution and innovative structural measures.

After two or three years of operation, the first results are now available regarding the energy-saving potential realised. Gerald Geiger (Head of the Central Construction/Energy/Technology Division) sums up how things have developed.

Spar opted for an LED-only lighting solution. What were the reasons for this decision, and what experience have you gained so far?

It turned out very soon that the lighting system is the second largest power eater at our sites, right after the heating & cooling systems. So obviously this is where we wanted to start. Our experience so far nothing but confirms our decision. We have been able to reduce lighting-related energy consumption by 25 percent while at the same time improving the lighting quality.

Your target is to reduce energy consumption by at least one third for each new or refurbished Spar supermarket by using new technologies. Spar's climate protection branches consume only half of the energy used by a conventional supermarket, thus saving up to 80 tonnes of CO2 per year.
What are the results with respect to these ambitious targets after the first two years of operation?

After more than one year of operation of our SPAR climate protection supermarkets in Murau (Styria) and Vienna (on Engerthstrasse), it is now clear that these two sites use 58 percent less energy than before the complete redesign, which is an incredible result. Of course we monitor these results, putting them in proportion to conventional SPAR supermarkets of similar size as well.

How are these savings measured; is there a specific monitoring system for the various areas?

330 systems are currently being monitored; this number increases continuously. A variety of key figures are determined here (power consumption per m² of retail space, hours of operation of the lighting system, gas and water consumption, standby losses and the like). We make every effort, including this monitoring, to ensure that our supermarkets' energy efficiency is continuously improved. Moreover, the monitoring system allows us to check new technologies in detail for their actual savings potential.

You deliberately set an example in terms of climate protection. Among other things, the supermarkets in Murau and Vienna were awarded Gold certification by the Austrian Association for Sustainable Real-Estate Management (ÖGNI).
How do customers, suppliers and staff members respond to the topic of sustainability?

Climate protection and sustainability have by now been firmly established in our society. We are getting highly positive feedback to our efforts in this respect, both from our customers and our suppliers and staff members.
