Best Practices - Background Info
High energy efficiency building-districts will refer to the whole system developed through:
- New and Innovative generation system integrating RES.
- Advanced electrical and thermal storage systems and thermal energy recovery systems from waste water and ventilation.
- Integration and Interaction of the systems: building to building and building to grid.
- Improved efficiency on building services and networks.
- Reduced energy demand at building level.
District retrofitting synergies represent a good opportunity to archive the true scale needed to optimize carbon emission reductions and achieve short-term payback periods. However there are only a few public district retrofitting projects accomplished as yet, and the selected examples for their significant contribution to the promotion of energy efficiency and/or renewable energy, are usually limited to building scale.
In total, 80 Best Practices or case studies have been gathered and documented in the data format sheet. Each case study has been classified according to building use (i.e healthcare, schools, academic, cultural, office, accommodation, etc) but contain additional information related to building characteristics, technical aspects and financial issues as follows:
All low-energy retrofitting projects face the same financial barriers such as budget limitations. Many decision-makers tend to consider initial costs, rather than operating, maintenance or life-cycle costs, therefore hindering the implementation of medium-long term cost effective solutions like RES or other innovative high performance solutions that yield more ambitious energy reduction targets.
These case-studies have identified some successful examples of financial mechanisms used to fund this type of interventions as well as utilizing innovative technological solutions and achieving successful energy reductions.

This Section gathers various examples of Public Buildings in Europe which have been retrofitted to a high level of energy efficient criteria and can be considered as best practice. The criteria include the following achievements:
- Low renovation cost (about 50% of a new building.)
- A wide improvement in energy use, moving from more than 300 kWh/m² to less than 50 kWh/m² per year.
- Lower CO2 annual emissions.
