5.2 Prepare an energy retrofitting plan for the whole building stock
Urban planning as a way of reducing energy use
The problem at handA city is made up of a multitude of buildings, not just those belonging to the local authority whose management has to be exemplary. Blocks of flats, detached and semi-detached houses account for around two thirds, with the last third consisting of tertiary buildings: public or private office buildings, hotels and restaurants, shops, leisure centres, hospitals and health centres, secondary schools and universities. A city’s building stock accounts for around 50% of its energy use.
These buildings are extremely diverse. Some are very old, even historic, whilst others are more recent and their thermal quality may vary from 1 to 10.They may be occupied by owner-occupiers, landlords or tenants. The spectrum of possible management and decision-making systems is extremely vast and the solvency of owners is variable, as is their sensitivity to energy costs.
And using the very generic term of “buildings” just adds to the confusion.
ProposalPrepare an energy retrofitting plan for the whole building stock of a territory covering the entire “building” sector so as to have an overview of the stock’s condition and the diversity of its energy features.
The plan should specify the energy, economic, social and financial challenges that have to be met in order to reach a “factor 4” trajectory by 2050. This means defining the level of stakeholders involved so as to integrate their decision-making processes and propose adequate energy retrofitting instruments.
