Örebro

In Örebro (Sweden) several buildings in different areas of the city are pilot sites of the BECA project:

  • Varberga – 180 dwellings
  • Pålsbodagatan 13 & 15 – 24 dwellings
  • Drottninggatan 33-37 – 48 dwellings
  • Örnsköldsgatan 147-151 – 45 dwellings
  • Björkallén 26-68 and Rosta strand 35-57 – 33 dwellings
  • Restalundsvägen – 101 dwellings.

 

The BECA pilot site service includes a Resource Usage Awareness Service (RUAS) to tenants on cold and hot water as well as a Resource Management Service (RMS) of indoor temperature to optimise the heating system. Within the project, the existing systems of the houses will be improved by raising the awareness for consumption through access to and visualization of consumption information. The tenants will have access to their consumption data both through their invoices and via a web service. All measurement data will be collected in a database, allowing a third party supplier to add new services such as visualization of consumption data via mobile phone.

The project partner ÖrebroBostäder expects a reduction of hot water use by at least 22 % on average and approximately 7 % on cold water. With better control of the temperature ÖrebroBostäder expects that the energy for heating will be reduced by 4 to 6 %.

Resource Usage Awareness Service (RUAS)

Service Description

During the project the hot and cold water consumption is a free service and included in the rent. Every month the tenants get their invoice where they are able to see their consumption costs for water. If they want more information or if they would like to check the consumption in detail, they are able to use a web portal. Tenants will have access to the web application through the internet where they can follow their consumption of water and inside temperature. The consumption is indirectly measured with units measuring temperatures and the total consumption in the house distributed across dwellings according to temperature. The service shall work as a motivation to save water.

Resource Management Service (RMS)

Service Description

Heating costs are included in the rent. It is adjusted in the long-term according to changes in consumption and price of resources. The maximum inside temperature in all dwellings will be set at a maximum of 21 degrees to avoid tenants overheating their flats. The frequency of temperature measurements is set to 15 minutes. The expectation is that this will allow for savings of 4 to 6 %.
