Siemens cooperates with Marriott to reduce its CO2 emissions

23 January 2014

Siemens cooperates with Marriott International, the leading hotel chain, for the energy and environmental upgrade of its buildings globally. The first results of this cooperation are very positive. With its innovative Energy Efficiency Program (EEP), Siemens is the ideal partner to help Marriott achieve its environmental goals, including the energy efficiency enhancement of its hotels in Europe, the reduction of CO2 emissions by 10% on an annual base as well as the reduction of water and electricity consumption by 20% by 2020.

With its Energy Efficiency Program, Siemens provides its clients with transparency over their buildings. As part of this process, Siemens collects usage data, analyzes it, and develops proposals for building optimization. The measures can range from fine-tuning existing building management sys-tems to planning and implementing a comprehensive overhaul of the various building disciplines.

The first project selected by Marriott for energy modernization was the Paris Charles de Gaulle Airport Marriott Hotel, and located in Roissy. Siemens completed the upgrade of the ventilation systems after only one-month projects. At the same time, it implemented the visualization and remote monitoring programs. As a result, the energy costs and CO2 emissions fell by 15 percent during the first six months of operation. In addition, electricity and gas consumption at the Marriott hotel in Roissy were reduced by 6 and 17 percent respectively, compared to the second half of 2012.

As a global company with offices in more than 160 countries, Siemens is the ideal partner for the implementation of Marriott’s international program, in Europe and ultimately in all locations worldwide.  For the moment, the first phase of the Marriott Energy Efficiency Program is underway, with energy modernization being implemented in 20 European hotels. The savings that will be reached should be between 10% and 15%, and the investments needed are expected to be paid back in three years.

With almost 3,900 hotels in 72 countries, Marriott is one of the world's leading hotel chains. Its 18 brands include Ritz-Carlton, Renaissance Hotels and Courtyard by Marriott. In Europe, the company has almost 290 hotels. Since 2007 Marriott has been committed to protecting and preserving the environment through sustainable operations.
