At the beginning of the LEAF project, only one owner in this building was interested in participating in the project. This owner saw involvement in LEAF as a great opportunity to reduce their environmental footprint and save energy. Other owners were then persuaded to join discussions about retrofit given the benefits of installing energy efficiency measures. These included improved comfort and energy ratings, and increased property values.
The following measures were recommended to owners during the project: external insulation of one façade and internal insulation of walls, double glazing, roof insulation, a mechanical ventilation system and a new gas boiler.
Unfortunately, none of the recommended measures were installed within the timeframe of the project. Owners remain interested in retrofit but decision-making proves to be difficult in this building given that the only time they meet is at their general assembly held once a year.
