YIT SIGNED A SIGNIFICANT SERVICE AGREEMENT ON THE PRODUCTION OF COOLING         
ENERGY WITH OUTOKUMPU                                                           

YIT Industrial Services will realise an energy-saving project at Outokumpu's    
steel mill in Tornio, Finland; the scale of the project is extremely large in   
the country. In the project, YIT will replace the Tornio cold rolling mill's    
existing system of 50 separate cooling compressors with a new cooling system    
based on absorption technology. The energy efficiency project will result in    
annual savings of 11 GWh of electricity. The reduction in CO2 emissions is 6,700
tonnes.                                                                         

In absorption technology, district heat produced from process lost heat is      
utilised in producing cooling energy. YIT's and Outokumpu's project is the first
industrial application based on this technology in Finland. Previously, YIT has 
realised projects for the recovery of process waste heat at the Tornio mill, and
the operating energy of these processes can be used in the new project.         

"The recovery of process waste heat generated in industry makes is possible to  
produce affordable cooling energy. These opportunities are plentiful in the     
Finnish industry. State energy subsidies are significant in terms of the        
profitability of the investment," Seppo Hyppönen, unit manager at YIT, reports. 

The agreement between YIT and Outokumpu represents a new kind of a service      
concept for industry, in which the agreement also includes future operation and 
maintenance of the plant in addition to ESCO service. YIT will build the new    
cooling centre with pipelines and distribution equipment and take care of the   
plant's operation and maintenance for seven years.                              

"This project is truly significant in terms of saving energy. The availability  
of a central cooling system is high, and it is also a very cost-efficient       
solution," Hannu Hautala, SVP of Tornio Works says.                             

The new cooling system will be commissioned at the Tornio mill towards the end  
of 2011.                                                                        

YIT is the leading provider of industrial energy efficiency projects in Finland.
