The European project ECOLISH promotes energy efficiency in existing residential buildings with the focus on freehold flats of persons with low income and social housings. The buildings are characterised by high energy use, due to poor thermal insulation and poor energy efficiency of heating installations, poor thermal comfort and indoor air quality. Major barrier is the lack of financial means to invest in improvements. Private organised energy exploitation and energy performance contracting are potential solutions for this problem. Within the project energy exploitation and performance contracting is organised, elaborated and evaluated on four pilot locations:

The ECOLISH consortium is composed by expert organisations in the four pilot locations. Coordinator:

General guidelines and conditions will be given on how to come to energy exploitation companies with residents and concerned parties as shareholder and energy performance contracting including a model contract.

Energy Exploitation and Performance Contracting for Low Income and Social Housing


Objectives Energy saving and CO2 reduction in residential buildings in EU has the highest potential of all sectors and a wide variety of technologies is available. But promotion of energy efficiency faces also a number of barriers. Especially people with low incomes who own their apartments and building societies with social housings have to deal with financial limitations and barriers. ECOLISH aims for an integral technical and financial solution that allows the improvement of this specific building stock.

Description of the work Pilot projects are organised on four locations in Europe (Netherlands, Latvia, Greece and Hungary), each representing a specific situation (building type, ownership and climate). For each location an energy exploitation company with different parties involved (including residents) as shareholders will be formed.

Heerlen in the Netherlands

Pécsvárad in Hungary

The quarter Vrieheide is situated in the north-east of Heerlen. The district has a total area of 15 hectares and contains 1045 houses. Most of the families have a low income and half of them are unemployed. A cluster of 837 single family dwellings, built in 1960, has the biggest problems with energy consumption and indoor environment. 75 percent of the dwellings are owned by residents, the remaining by a private property investment company.

Not only energy performance contracting for apartment houses is taken into account, but also the possibility to include a number of other buildings as municipal office building or cultural centre, residential home for the elderly, school or kindergarten. The different buildings in combination with habitation give an opportunity for the exposure of a local private owned energy exploitation company with participation of all local shareholders.

Ogre in Latvia

Pieria in Greece

An area with ten houses was selected for the project. Altogether the blocks contain 238 apartments with 520 inhabitants. 83 of them are children and the income of the residents is below average. The people own the flats but a municipal agency is still responsible for maintenance services. According to the results of a survey the residents criticise the cost and the condition of the heating, the insulation and condition of the roofs, the situation in the staircases, and - as highest naming - the missing of parking places.

The 26 buildings under examination were erected in two different periods in 1974/1977 and in 1978/1981 in an area of around 8 hectares. 249 apartments are situated in 24 houses and 10 shops in the other 2 houses. The houses are insufficiently insulated and most apartments still have the original wooden window frames. The central heating systems vary in every building and don’t have a joint management for the installations. The residents own their apartments and have a low income.

Expected results A detailed implementation plan for the addressed target groups as municipalities, housing corporations, real estate developers and utilities will be developed. Extended activities around energy exploitation and performance contracting will be promoted. Overall it should induce CO2 reductions of 10,000 tonnes per year in the pilot locations.
