Short Description

The renovation was started in 1997. The aim was to achieve an energy saving of 35% and retrofit the building. Preparations and planning took 5 years. The complex renovation was financed by apartment owners and a bank loan.

Key Elements

Certification

An energy audit has been carried out for the building.

Work with Residents

In the first phase of the project (more than two years), the aims and plans were discussed with all 60 apartment owners who had to invest to the project. This helped the homeowners to understand the process of retrofitting and ideas of energy saving.

Funding

The project was financed by homeowners until 2007. From 2007, the project was financed with a bank loan of 1.8 million EEK (€115,000). The Apartment Association received subsidy for renovation of 61000 EEK (€4,000) from Export and Guarantee Fund KredEx.
