EA-SAS Building

EA-SAS Building Digital Twin is analysing and evaluating the building’s energy data in real-time. It includes AI algorithms which allow to minimize energy consumption for heating, hot water preparation, cooling, ventilation. Together with AI control, includes interface for third parties smart energy meter data collection, firefight control, etc.

During the implementation of the system, a detailed inventory of the building’s engineering systems is performed, and a mathematical model is created – the digital twin that fully describes the indoor microclimate and engineering systems.

By connecting to the online graphical user interface every minute, user of EA-SAS Building is able to see the operating modes of the systems and its CO2 savings in real time. CO2 savings can also be displayed on external devices (building monitors, etc.).

EA-SAS Digital Twin is dedicated for:

  • Office buildings
  • Shopping malls
  • Schools
  • Kindergartens
  • Hospitals


  • Demand peak shaving up to 20%
  • Reduce energy production up to 5%
  • Reduce district heating network losses up to 30%
  • Reduce energy production costs up to 5% due to optimum production scheduling
  • CO2 reduction up to 5%


Vilnius city municipality together with Energy Advice joined an Intelligent Energy lab initiative. The purpose of this initiative is to create open platform for generating and implementing smart energy solutions for Vilnius city. For Intelligent Energy lab initiative, Vilnius city municipality building at Konstitucijos av. 3 was selected for increasing energy efficiency with the help of state-of-the-art digitalization methods. Energy Advice used EA-SAS analytical system to read smart metering data and create digital twin model for building in Konstitucijos pr. 3. Digital twin allowed to determine reasonably and wastefully consumed thermal, cooling, electrical energy and water amount for each operation hour. During the project, Dashboard window with reports was created at EA-SAS program that allows to easily track energy consumption indexes and promptly respond for the responsible personnel. During the project it was determined that the potential to reduce energy consumption can reach 30%. Services were provided with great efficiency and quality. 

We recommend cooperation with UAB „Energy Advice“.
