In some tenant areas had appeared climatic uncomfortable ambient air conditions. Winfried Haas has been assigned for troubleshooting. He has analysed the operation conditions and the function of the cooling production plants as well as of the major air handling units. He has undertaken some energy modelling of the air conditioning process using state-of-the-art computer simulation tools in order to solve the issues.

Climate change project for germanwide 800 properties
/in Energy savings and CO2-reduction /by Winfried HaasConsulting on awarded energy performance project for 800 properties
Winner of the European Energy Service Award 2012 (EESA)
Consulting on europeanwide largest energy performance project with notable reduction of GHG-emissions and energy consumption.
Advising the Contractor Imtech on the development and implementation of the Lorac-Imtech-Efficiency-Project for 800 properties of Lorac S.a.r.l. (Luxemburg) in Germany. The motivation for the main user of this building, the Deutsche Post AG, were the high savings of CO2 emissions, which constitute a notable contribution to their Go Green Initiative.
The Imtech Contracting GmbH has implemented energy efficiency measures in 800 properties, which are almost used by the Deutschen Post AG. With a volume of more than 400 Million Euro this project is the largest energy efficiency project in Germany and Europe. Tenants, building owners and energy service company are profiting of energy cost saving of more than two Million Euro per year. The reduction of CO2 emissions are 17.000 tons per year.
This project is winner of the “European Energy Service Award 2012” in the category “Best Energy Service Project”. (source: EESI)
