Romania: Geothermal Energy for Energy Security in an Elderly Home

In a concerted effort to modernise public administration buildings, Alba Iulia Municipality partnered with the company SC Societatea de Inginerie Sisteme SA to develop an innovative method of harnessing thermal energy from geothermal sources to ensure the energy safety and sustainability of an elderly home.

Alba Iulia is a historic city in the Transylvania region known for its star-shapped fortress which is the largest and best preserved in Romania. The Municipality takes an active approach to increasing the quality of life. This includes efficient measures for improving the management of public property.

This project will improve the thermal and electrical infrastructure by developing a technical solution based on a microgrid approach that produces energy from geothermal sources and ensures energy safety for the Alba Iulia nursing home. The technical solution developed in the project will ensure connectivity between the heat pumps installed as part of the project and the photovoltaic panels which were alreday installed on the building. This will ensure energy security and efficiency in a building that previously consumed a lot of energy. It will also reduce CO2 emission with 50%. Besides all of this, the temperature indoors becomes more comfortable for the elderly residents.

Partnership with a Romanian company 

Alba Iulia Municipality is partnering up with SC Societatea de Inginerie Sisteme SA, one of the most important providers of solutions and services in the domain of process control in the areas of energy and utilities, oil and gas, refineries, petrochemistry, food industry and civil buildings in Romania. 

With financial support from the EEA and Norway Grants through a call under the SMEs Growth Programme in Romania, Societatea de Inginerie Sisteme SA managed to create a microgrid pilot application which will be put in practice for the elderly home in Alba Iulia. 

Societatea de Inginerie Sisteme SA will develop the methodology for the microgrid design. The main goals is to incorporate very important attributes of the microgrid so that it is controllable, interconnectable, reconfigurable and integrated in the main grid.


Microgrid for an elderly home

The building of the Alba Iulia Home for the Elderly has a number of deficiencies and dysfunctions, and those have increased over time. The project will improve the energy efficiency of the main building of the home of elderly and increase indoor comfort by installing geothermal pumps, replacing the thermal distribution system and monitoring the performance obtained through an intelligent Building Energy Management System (BEMS).

The project will contribute to the local development strategy to:

  • Increase the energy security supply in Alba Iulia and decrease CO2 emission by using energy produced from renewable sources
  • Ensuring comfortable, accessible and sustainable life conditions and a clean environment for the community
