Innovative 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 and monitored building air tightness
Heat recovery from waste 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)
Innovative 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 as electrical storage to better match supply with demand
 Charge station for electrical vehicles and bikes
Innovative actions in Växjö
District heating and cooling energy supply
 Energy produced from waste heat coming from central CHP-process based on
bioenergy, a crematorium , local industries
 Local 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.
 Local production of heat/cooling/electrical energy from new innovative device
(Entrance-ORC).
 Heat driven appliances (dishwasher, wash mashine)
 Smart Meters (use of electricity, heat, hot and cold water and info)
