This is the good practice's implementation level. It can be national, regional or local.
About this good practice
The condominium association Boken in the city of Kristianstad manages 5 residential buildings with 109 apartments. Additionally, there are 11 other facilities. The total area is about 6500 m2. The houses were built in the years 1954-55. The Association Boken is a private association with building containing a number of individually owned apartments. In recent years, the association has implemented measures to energy-efficient the houses.
By 2016, the association decided to go one step further by investing in the production of electricity for its own consumption. There were several residents in the area who wanted the association to invest in solar cells. In spring 2016, the association held an annual meeting. There was raised the issue of installing solar cells on the roof to produce large parts of the association's electricity supply itself. All members were positive about that idea and in October 2016 it became reality. Then 422 panels were installed with a power of 109.7 kW on the five roofs at Näsby. In November 2016, the plant was put into operation and generates electricity for the 109 apartments in the association.
The cells should generate just over 100 MWh/year. This corresponds to one third of the association's electricity consumption of approximately 300 MWh / year.
The electricity from the solar cells is used primarily for consumption in the apartments, laundry rooms and common areas. The association uses most of the produced electricity itself.

Resources needed
The cost of the investment was 198 000 Euro.
The association has received 30% of the cost in the national contribution, about 60 000 Euro.
The payback time was estimated to 14 years!
The annual saving in 2017 was about 8 000 Euro.

Evidence of success
In 2017 the solar cells generated about 150 MWh, that was more than expected! The production in 2018 seems to be even higher.
Potential for learning or transfer
This is the first condominium association in northeast Scania and Blekinge who has installed a solar cell facility. They have an important function to inspire other tenant-owner associations and private owners of multi-family houses! So far, it is unusual with condominium associations that invest in their own electricity generation.
