Better energy management in buildings can achieve up to 25% in reductions in electricity consumption in just a few months. This is the conclusion reached by TEDS4BEE, the European project funded by the EC comprising 12 European partners, 5 of them Spanish (Ferrovial Servicios, Indra, Madrid Network, Universidad Politécnica de Madrid and CI3). The project has been deployed the EMMOS (Energy Management and Operational Monitoring System) digital service in 16 European buildings.
This platform is based on software that controls, analyzes and contrasts the energy efficiency of buildings.
Energy efficiency projects play an important role in fulfilling the European development agenda, specifically the 20-20-20 target. According to the EC, while the objectives of reducing CO2 emissions and increasing the use of renewable energy are expected, it will require a greater effort to reduce energy consumption and this is where energy efficiency projects such as TEDS4BEE are key.
Whereas the focus in the previous six months was on improving EMMOS as well as preparing the pilot buildings on an experimental basis, since July 2014, the project has centred on reducing energy consumption and the carbon footprint.
Currently the project is in the data gathering and analysis phase in all of its pilot buildings. Treatment of this information is leading to a series of corrective measures and as a result there have been significant savings in total energy consumption.
For example, at the Emergency Center of Vojvodina in Novi Sad (Serbia), EMMOS has allowed the administrator to carry out various modifications including:
• The regulation and optimization of the heat recovery system
• Appointment of time scheduled for VRV (Variable Refrigerant Volume)
• Automatic change of set points in all air handling units
It has also helped to introduce changes in BMS (Building Manager System) algorithms, the installation of new sensors for better control and the identification of energy gaps, resulting in an important improvement in energy efficiency throughout the building.
These actions have resulted in significant savings. These include the reduction of about 25% in the consumption of sanitary hot water and more efficient management of the fans, achieving savings of 13%.
At this point there are still six months to go. The work will focus on quantifying improvements, thanks to the corrective actions taken, and extrapolate the data obtained in each building to get results for the entire project. All these results, to be announced at the wrap-up conference, will show TEDS4BEE as successful in managing energy efficiency in buildings and EMMOS as a useful cost-effective and environmentally friendly tool.
The TEDS4BEE project, with a budget close to 4 million euros, is part of the Competitiveness and Innovation Program (CIP) that the European Union adopted in 2007 and promotes the use of Information and Communication Technologies (ICT), green technologies and renewable energy sources. The projects developed in this program must integrate the creation of innovative digital services in order to achieve improvements in energy efficiency and reduce emissions in cities (between 15% and 30%), promoting and accelerating the adoption of these services on a large scale.
In line with these guidelines, the project brings together in its consortium institutions covering the entire value chain of energy efficiency in buildings (ICT suppliers, energy service companies and owners of public buildings) and others that are closely related (universities, research centres and business associations).
