30 REAL ESTATE MARKET Investors Developers Construction Companies Owners

31 REAL ESTATE MARKET If well designed, it is possible to reduce the cost of green buildings. Green Buildings are more attractive on the market: Reduced operation cost Higher productivity Value stability

32 REAL ESTATE MARKET

33 REAL ESTATE MARKET US Market By 2015 more than 40% of non residential buildings will be green Green building market: 2% in 2005, 12% in 2008, 35% in 2010
