Contact Information

Lund is a medium-sized university city with a research-intensive industry. The town dates back a thousand years, but the number of inhabitants has grown, largely during the last century, and a great number of the buildings from the 1960s and 1970s now need retrofitting. Almost 90 % of the heat demand in the city is supplied by district heating, and the hospital and some office buildings are connected to a district cooling network.

The focus of the CITyFiED project are 16 houses in the Linero district spread over 40 400 m2. The retrofitting aims to reach a higher energy standard with maintained affordability for the tenants. Simulations of the energy-efficient measures included in the retrofitting strategy were carried out during the first part of the project. They showed that the original final energy savings targets not only can be accomplished but will be surpassed.

The first round of analysis showed that the total final energy savings in Linero would reach approximately 58 kWh/m²/yr. This value is better than the project’s original target of achieving a reduction of 31 %. Primary energy savings at the site have been established at 19 % of the original primary consumption and greenhouse gas emissions are to be reduced by 26 %. Four indicators for indoor environmental quality in the buildings were analysed – operative temperature, relative humidity, CO2 levels and the Predicted Percentage Dissatisfied (PPD) index to measure ambient climate dissatisfaction. None of the indicators show critical levels in the current buildings and no negative effect has been observed from the calculations of the renovation measures. At the heart of reaching these performance targets are the research, planning and efficiency of the extensive renovation strategy.


The overall gross floor area of 40 400 m² has been refurbished in the Lund demo site affecting 1150 people. The annual final energy saving estimate is 2343 MWh. The total CO2 emission savings estimate amounts to 404 tonnes per year.

Great efforts were invested in improving the living conditions (both indoor and outdoor) in the Linero district in an economically sound way so that the tenants can remain in the area. Frequent meetings with the tenants have been carried out to ensure high acceptance of the measures.


The Swedish partners have established structures for working together to safeguard the systemic approach that characterises the project. These are a steering committee ensuring a high-level awareness of the CITyFiED actions and methodology, a communications group to speak with a united voice and engage with residents, and collaborative working days.

The key measures implemented in Lund are:

Energy efficiency in buildings

  • Retrofitting the building envelope
  • Building services (HVAC and lighting)

Energy systems integration

  • District heating and cooling
    • Smart district heating
Mobility & transport: 
  • Clean fuels and fuelling infrastructure
    • Fast charging points for electric vehicles
  • Building energy management system
    • Monitoring systems for providing best indoor comfort conditions and energy savings
  • ICT as planning support
  • Demand response
    • Numerous full-scale concept solutions to complement structural advantages will include smart grid monitoring initiatives – with visualisation tools and demand responsive meters
