@ Michael, 6x less makes perfect sense: if 6/6 is 6x MORE than 1/6, then logically 1/6 is 6x LESS than 6/6, therefore 6x less = 1/6

Did you mean 1/6 the amount of GHG emmisions? 6x less does not make logical sense. 6x 100 # of GHG is 600#. Are you actually consuming GHG to operate this building?

Elithis Tower sets the sustainable example in Dijon 

The Elithis Tower, designed and constructed as the world's most environmentally sound building, has been revealed in Dijon, France. Touted as the first positive energy office structure, the tower creates more power than it uses and produces six times less greenhouse gas emissions than classic commercial buildings. From design to material and user behavior, the Elithis Tower applies the latest sustainable development techniques.

The Elithis Tower was initially a theoretical challenge Thierry Bievre, General Director of the group Elithis Engineering, put forth to his team. Specialized in technical fluid installation and environmental efficiency, Bievre wanted to know whether it was possible to create an environmentally sound building at equal cost to a traditional structure. Supported by the City of Dijon, France, and ADEME Bourgogne, France, Elithis Engineers called upon renowned architect Jean-Marie Charpentier (Arte Charpentier Architects, Paris, France) for close collaboration. Together, the group rose to the challenge to create the 54,000 sq ft, ten storey building which marries aesthetics, urban integration, comfort, energy and environmental performance.

To achieve this combination, a complete environmental ideology was designed. Materials for this project were chosen according to their global environmental impact. The exterior of the building is made of wood and recycled insulation, while aluminum, which strongly impacts the environmental, was used sparingly. Bay windows were selected to bring in natural light. To complement this, a special nomad was designed by the Elithis team to guarantee a comfortable level of light is available without excess artificial illumination. To take advantage of solar energy (warmth and natural light) without the associated inconveniences (excess heat and blinding brightness) a solar shield was designed by the Elithis engineers allowing natural light to enter the building while filtering out excess heat and blinding light. Power is also harnessed from over 330 solar panels on the building's roof. In addition, a triple flow system has been patented by Elithis, which harmonizes energy in the building. Office energy emissions (from computers, photocopiers, lights, people…) are recovered, saved, harnessed and reused within the Elithis Tower.

To match the engineering and architectural commitment to energy efficiency, everyone in the Elithis Tower, from owners, tenants, leaders and academics, to administrators, employees and visitors, is empowered to participate in the environmental efficiency of the project. An increased level of consciousness is encouraged, meaning that people within the building are aware of their responsibility in energy consumption. Individuals will be inspired to make positive choices to minimize energy use (in terms of paper, water, transportation…) and reduce the environmental impact users have on their environment.

Because the Elithis Tower is such an innovative experience, the building is designed to facilitate evaluation and understanding. More than 1,600 sensors have been installed to meticulously examine and analyze energy and emissions. Daily energy consumption will be posted and displayed on a special public sign, in full transparency for building greenhouse gas emissions and environmental impact. The Elithis Tower is the first active environmental laboratory of its kind and scientists, researchers and universities are invited to visit the Elithis Tower and evaluate the information collected in this project.
