Delft, The Netherlands
Delft, with 100,000 inhabitants in the province of South Holland between Rotterdam and The Hague wants to become a CO2 neutral city. In relation to that ambition, the City council adopted the Update Climate plan 2008-2012 with the objective to emit 15% less CO2 by 2012, raise the share of renewable energy to 5% of the total Delft energy consumption in comparison to 1990 and use 15% less energy.
The CONCERTO approach
A new public private partnership (PPP) district heating company was established in Delft, producing, distributing and supplying an equivalent of nearly 20,000 homes with heat and hot water. It is one of the major projects within the DELFT climate plan. It ensures a CO2 reduction of at least 18,500 tonnes.
In the Buitenhof area in Delft, a new energy efficient sports hall of 2,923 m² is built as well as 88 student premises. The building is connected to the district heating and possesses individual meters. The new sports hall is about 78% more energy efficient than the old one. The energy use is 11% less than national regulations in the sports facilities and 23% less for the student premises.
300 new eco-building dwellings, with a high percentage of social housing, are constructed in the new housing area of Harnaschpolder. They show high energy-performance and are connected to low temperature sourced district heating. The aim is to reach an average of the energy demand for space heating of 18-20%. 70% of the heat demand is supplied by Renewable Energy Sources.
A refurbishment and upgrading programme is taking place in high-rise buildings in the Poptahof district of Delft. Around 800 dwellings will be renewed. 84 apartments and 10 studios have been refurbished to new standards. 58 new energy efficient dwellings and a vertical PV system have been constructed. The total number of dwellings within Poptahof increases from 300 to 1,300. The dwellings are mixed by about 40% low-rent social housing, 20% private owned social housing and 40% private owned housing.
Use of Renewable Energy Sources
• Photovoltaics
• Geothermal energy
• Hydroelectric power stations
Low Carbon Technologies
• Mechanical ventilation with heat recovery
• District Heating
• Insulation
• Gasfired heat pump
Highlights
Daily energy use of the tenants is available through specific individual metering both for heating and electricity. The monitoring and eva-luation is done by EREA, the local energy agency. Feedback for the tenants is being developed.
