Belgrade

The pilot site Belgrade (Serbia) includes three buildings in the municipality of Palilula, City of Belgrade. The three high rise towers have a total surface of about 9,300m² building area with 184 dwellings. Built in the 1960’s, the buildings are typical representatives of that period of Serbian housing with poor thermal insulation and high energy consumption.

 

The dwellings in Tower A equipped with the BECA services range in size from 48 m² to 57 m². The average level of education of tenants is medium; a lower number has a university degree or elementary education. The tenants’ internet access rate is rather low (30%). They mostly perceive the “economic savings” as the benefit of BECA. Together with the project partners University of Belgrade – Faculty of Mechanical Engineering (MEB), JKP Beogradske elektrane (BEOELEK) and Belit, the project aims at energy savings over 15%. The services offered in the pilot site are based on monitoring data for electricity, water and energy consumption.

Resource Usage Awareness Service (RUAS)

Service Description

Tenants will have access to an internet portal that gathers information on their water, energy (for heating) and electricity consumptions. Heating energy consumption measurements will take place through heat cost allocators. It has been agreed on data provision to the server and data exchange protocols (web service / XML). An agreement is about to be reached with the water and electricity provider for making these measurements available using their own metering equipment and for a data exchange with the server.

Resource Management Service (RMS)

Service Description

The fuelling of the boiler facilities will be changed from coal to solid biomass and the control of boiler operation will be improved. Tenants can control room temperatures. Information of the tenants’ consumption are available, as well as a “cost calculator”. The service will be implemented as a web-based information system.
