In buildings many factors need to be treated in combination in order to reduce their energy consumption (building envelope, energy systems, control systems, meteorological conditions, user behaviour, etc.). Energy managers do not always have the necessary tools for obtaining and analysing data in an integrated way in order to reduce or contain the energy consumption in their buildings optimally. The decision-making process when it comes to carrying out the necessary actions for improvement is a key factor for success

SIE, Energy Information System

The application to manage all your bills and consumptions from your suppliers to save time and resources.

More than 250 institutions managing their contracts with SIE


Simulation Supported Real Time Energy Management in Building Blocks

Use power when the wind is blowing
This is also known as Demand – Response (DR), when consumers adjust their use of electricity to match what is available at the time.

SIM4BLOCKS is creating systems that encourage consumers to match their energy demand with supply rather than matching supply with demand.

What SIE makes for you

Some success stories

A sport center in Lleida

SMARTSPACES 2012-2014, Saving energy using ICT



The energy optimisation service in “Barris Nord” achieved savings of 30% in Gas and 10% in Electricity, around 631 MWh and 64.000 €, avoiding 104 tCO2 emissions, without affecting users comfort.

The city of Manresa

2006 – 2016, TEN YEARS OF SIE managing all city facilities



The municipality manages with SIE more than 150 buildings, nearly 200 electrical panels of street lighting and 300 hydrants, by keeping the expense in despite of the continuous growth of the city.

The SIM4BLOCKS project

DEMAND RESPONSE or Use power when the wind is blowing



The Spanish pilot in Sant Cugat del Valles consists of 6 blocks of adjacent buildings composed of apartments, offices and commercial premises which together offer a great unit to study …


In order to achieve a real and continued saving we apply a basic methodology that consists of 4 points, which are technologically supported by our own ICT developments. These 4 points are:

Data collection Data collection involves continual energy monitoring of the installations, an energy audit of buildings and collection of feedback from the users. User feedback covers both evaluation of the level of comfort and suggestions for operational improvements. Data analysis and Improvement proposals Once collected, the data is analysed through the BeeData Analytics, then programming adjustments are made to improve the use of the facilities, the remote management and the control systems. Monitoring and management of proposals Once the improvements have been made we analyse the results and develop tools for visualization of the results and of the effects of subsequent actions. User Feedback Continuous training and communication actions involving building users are proposed. These actions include use of tools such as a website and mobile applications.
