Slide8Innovative actions in Växjö 31 500 m2 dwellings (376
pcs), built 1973, 141-171 kWh/m2
,a Retrofit
Energy target: 75 kWh/m2/a (national building code 90 kWh/m2,a, heating, domestic hot water and building electricity for new buildings)New energy efficient windows New mechanical ventilation with high-efficient heat recovery Extra isolation of
attic joists
Improved

water
?
Two extra stories on top of existing buildings (solid wood frame
and almost passive house standard)Smart kitchen solutions (minimise use
of electricity, water and wrappings)Info-campaignes for tenants to affect ”energy”-behaviour and to minimise waste from food and wrappings (organic waste is used for central biogas plant)
Slide9Innovative actions in Växjö Electricity
distribution grid
Local
production with building integrated photovoltaic installations New efficient network components? (quality of electricity etc)ICT solutions for optimal use of renewable energy production (possible differentiated price?)Electrical vehicles and
electrical bikes will be available for rent.
Used

with demandCharge station for electrical
vehicles and bikes
Slide10Innovative actions in Växjö District
heating and
cooling energy
supplyEnergy produced from waste heat coming from central CHP-process based on bioenergy, a crematorium , local industriesLocal district heating system temperatures adjusted to lowest possible level (NODA) in order to provide best possible prerequisits for production
of electricity in central CHP plant and minimisation of heat
losses
.
