Energy Efficient Cities Initiative (EECI)
In 2000, the Armenian capital’s water utility, the Yerevan Water and Sewerage Enterprise (YWSE), entered into a five-year, performance-based management contract with private operator Acea Spa Utility (Acea). Over the contract period (2000-2005), the duration of water supply was increased from 6 to 18 hours per day, collection rates improved from 20 to 80 percent, and electricity consumption was reduced by 30 percent.
Between 2000 and 2008, the City of Campinas, in the Brazilian State of Sao Paolo, developed a successful energy management program, increasing tap water connections by 22 percent without additional energy requirements. These new connections, provided through its water and sanitation utility SANASA, primarily serve the urban poor living in peri-urban slums, or favelas. They enabled uninterrupted tap water service to reach 98 percent of the population of the city by 2008, compared to 88 percent in 2000.
By mandating low-energy building standards in sales contracts of city-owned land, the City of Münster (Germany) caused a market transformation that led to 80 percent of all new buildings constructed in 2010, even those not built on city-owned land, to follow the city’s energy efficiency requirements.
