renewable heating
• biomass
• biogas
• solar thermal
• heat pumps
• district heating
Smart District Heating
Energy networksHeating and Cooling
� Innovative and cost effective biomass, solar thermal and geothermal
applications
� Innovative hybrid heating and cooling systems from biomass, solar thermal,
ambient thermal and geothermal with advanced distributed heat storage
technologies.

technologies.
� Highly efficient co- or tri-generation and district heating and cooling systems.
Electricity
� Smart grids, allowing renewable generation, electric vehicles charging,
storage, demand response and grid balancing.
� Smart metering and energy management systems.
� Smart appliances (ICT, domestic appliances), lighting (in particular solid state
lighting for street and indoor), equipment (e.g. motor systems, water systems)
� To foster local RES electricity production (especially PV and wind applications).

Smart District Heating
Why is this possible?
� Interaction with liberal electricity market
� Benefits from combining technologies
� Very cheap and high performing solar systems
“The Contribution of Renewable Heating and Cooling technologies
to the “Smart Cities initiatives” - Workshop February 9th , Brussels
� Very cheap and high performing solar systems
� Improved storage technology (simple/cheap)
� LARGE SYSTEMS ���� small storage losses

Smart District Heating
Many possibilities ���� Flexibility
Winter:
� High electricity price ���� run CHP, earn money ���� make cheap
heat
� Low/medium electricity price ���� run heat pump ���� make
relatively cheap heat
Interaction with liberal electricity market
“The Contribution of Renewable Heating and Cooling technologies
to the “Smart Cities initiatives” - Workshop February 9th , Brussels
relatively cheap heat
Summer:
� Low electricity price ���� run solar only ���� make free heat
� Very low electricity price ���� run heat pump ���� make free/cheap
heat
Smart District Heating
Solar:
� Produce free heat
CHP:
� Produce valuable
electricity ���� earn money
� Fast capacity regulation
(prod.) ���� earn money
Benefits from combining technologies
“The Contribution of Renewable Heating and Cooling technologies
to the “Smart Cities initiatives” - Workshop February 9th , Brussels
Heat pump:
� Produce cheap heat
� Fast capacity regulation
(load) ���� earn money
� Reduce storage volume
(prod.) ���� earn money
Storage:
� Gives flexibility
� Makes combinations
possible
Smart District Heating
Collector parameters
� The collector applied in the bases cases has
the efficiency parameters:
� n0: 0.815 (AR glass)
� a1: 2.43 (Teflon convection barrier)
� a2: 0.012
� Very cheap and high performing solar
systems
� Improved storage technology
(simple/cheap)
“The Contribution of Renewable Heating and Cooling technologies
to the “Smart Cities initiatives” - Workshop February 9th , Brussels
� a2: 0.012
� The collectors are place with:
� slope: 30 ° (low angle is optimum due
to shadows from row in front)
� azimuth: 0 ° (South)
� Row distance: 4.5 m (collector front to
collector front)
� Collector field installed ≈ 200 €/m²
Smart District Heating
Store parameters
� Water pit with liner (un-insulated to earth)
� The top of the store is assumed insulated with “LECA”; average insulation thickness
0.5 m
� Price: 20 €/m3
Improved storage technology (simple/cheap)

Status
� Project under approval by the local
authorities – end of public hearing 8/3 2011
� If approved – construction can start
