Pilot projects in Odessa

Approach

To achieve the overall goal of the ARCEE project, i.e. to increase the know-how of key stakeholders in the partner countries on energy efficient housing refurbishment and new construction, one central activity in the project is the practical preparation and if possible also implementation of energy efficiency measures in multi-family residential buildings. This is done in the frame of pilot projects which are realised in each of the partner countries.

The pilot project activities focus on the identification of suitable buildings (one or two per country), the visit of the buildings and the analysis of their current structural conditions and energy efficiency as well as the development of recommendations and refurbishment concepts. These activities are implemented by the German project partners Auraplan and IWO in close cooperation with the national partners and the administrations of the pilot project buildings. The involvement of the residents of the buildings is regarded as crucial aspect in this context.

The pilot projects in Odessa, Ukraine and St. Petersburg, Russia focus on providing consultancy for existing buildings which are in need of refurbishment. The project partners suggest a comprehensive refurbishment approach, but also analyse and present refurbishment variants. In Minsk, Belarus the construction process of a new multi-storey residential building is accompanied and recommendations regarding the energy performance, execution of construction works and liability aspects are given.

To learn more about the pilot projects in each country please visit the country subsections. Furthermore, you can find information on the project’s approach with regard to the pilot projects. 

Multi-apartment building in Marselskaya street

The building in Marselskaya street, 10 in Odessa was selected as one of two suitable pilot projects in the Ukraine. It was built in 1967 with prefabricated panels and represents the so called “hruschovka” building type. The building consists of 96 flats on 5 storeys and in 6 sections. The apartments are all owned by private persons who are organized in a homeowner association for the maintenance and management of their building. The homeowner association itself is member of the Odessa Housing Union Associations. Being interested in the elaboration of replicable refurbishment concepts for the main building types in Odessa, the Odessa Housing Union Associations support the ARCEE pilot activities.

In cooperation with all stakeholders, the project partner Auraplan has analysed the current state of the building with regard to the structural condition and energy efficiency. The main problems encountered are uncomfortable cold temperatures in winter times, increased temperatures in summer times and the lacking possibilities to regulate the heating system. Also, the roof needs to undergo repair. In order to get an overview on the saving potential of walls, windows, roof and floor, Auraplan calculated the energy demand of the building.

Based on these calculated data, different refurbishment variants have been developed. The project team recommends a complex refurbishment, starting with improving the building shell, tackling all building elements and improving the outdated technical equipment (one pipe system, so far without regulation) as well as the ventilation concept to avoid the mould problem. As additional aspect, solar collectors for hot water supply in summer time have been developed.

As a next step, local companies have elaborated a rough cost calculation. Based on these figures, two financing models (with different types of credits) were presented to the inhabitants by the local partners in the frame of a common meeting of inhabitants. During the common meeting, the inhabitants decided due to their economic situation to stop the activities and not to apply for a credit.

Multi-apartment building in Sakharova street

The building in Sakharova street is the second pilot project selected in Odessa. It is a typical panel series residential building which was constructed in 1984. The building consists of 288 residential apartments on 12 storeys. The ownership structure in the building is completely based on individual flat ownership.

In the frame of the ARCEE project, the project partner Auraplan assessed the energy efficiency of the building. This showed that the building is characterized by a poor energy performance standard with large heat losses and a poor internal infrastructure. The current heat demand of the building is 190 kWh/ m²a.

Based on the energy efficiency assessment, Auraplan suggested a modernisation of the building shell to improve the energy efficiency of the building. Several variants for improvement of the building shell’s thermal characteristics have been simulated. The developed recommendations contain five options for an energy efficient refurbishment, each with a different level of effectiveness of the refurbishment measures.

A simulation for a complete refurbishment variant, including all building elements showed a heat demand value of 43 kWh/m² a. According to the calculation, the building heat demand was reduced by about 130 kWh/m² a from the current heat demand.

Recently City Council of Odessa showed a lot of interest to pilot projects in Odessa conducted in the frame of ARCEE. A mayor of Odessa, Genady Truhanov is strongly interested in the pilot building on Saharova 42 Street, and committed to finance 50% of the costs required for refurbishment measures. Since there are no pilot buildings that underwent full refurbishment, the mayor of Odessa is very interested to implement such a project in Odessa in order to have the first energy efficiently modernized building in the country. Right now Auraplan in cooperation with the local planner is developing a refurbishment concept according to Ukrainian legislation and corresponding cost estimations. The refurbishment variants are planned to be presented to the residences in winter, and based on that the decision on renovation will be taken.

Training seminar in Odessa

Training seminar for house managers and representatives of homeowner associations addressing the question “How to engage flat owners in refurbishment of multi-apartment buildings” was organised in Ukraine (Odessa) in June 2014. The goal of the seminar was to support house managers and homeowner associations in the communication at different steps of a refurbishment. The one-day event included the following topics:

  • Preparation phase: evaluation of energy performance of the building to assess the need for improvement
  • Communication with flat owners on possible options (legal, technical, financial) and measures (insulation, change of windows, etc.) to increase energy performance of the building
  • Reaching a common agreement on refurbishment measures of the house by flat owners
  • Steps and measures of the refurbishment for improving the energy performance of the house.

Training seminar in Odessa (27.06.2014)

Experience in building refurbishment in Jelgava city, Latvia

ARCEE project's partner Mama-86-Odesa is organizing a seminar about increasing awareness on methods and means for improving energy efficiency in multi-storey apartment buildings. It will be held on 27-28 February in Odessa. The target group of the seminar is house management companies, municipalities and other organizations that are planning and implementing energy efficient measures. The chairman Juris Vidzis and technical director Olegs Kukuts from Jelgava Real Estate management Ltd. (Latvia) have been invited to take part in this event and present good examples on multi-apartment building refurbishment of Jelgava city.
