Rethinking efficiency in buildings

Efficient buildings save the day
It’s time to wake a sleeping giant. The report published by the energy consultancy Ecofys is the first to confirm and quantify the huge, untapped potential for energy savings at EU level, that can be achieved by retrofitting technical building systems.
It’s time to unlock the opportunities hidden behind concrete, glass and steel to create massive savings, more jobs and better places to live.

- 30% of total EU energy consumption is used to heat and cool our buildings
- 70% of an average household’s energy bill is spent on heating and cooling
- 36% of the EU’s carbon emissions comes from buildings
- 240bn Euro is spent by EU citizens on space and water heating per year
- 1 in 10 people in the EU struggle to heat their homes
- 110m citizens live in buildings with hazardous concentrations of pollutants due to inefficient ventilation

- 30% average potential energy savings by optimizing technical building systems
- 2 years average payback period
- 14% of the EU2030 energy efficiency target could be met by optimizing technical building systems
- 156 Mt CO2 emissions could be saved by optimizing technical buildings – the equivalent of the emissions produced by 82 million cars
- 67bn Euro could be saved on energy bills annually in 2030
- 300,000 jobs could be created in Europe by manufacturing and installing energy efficient products and services
Unlocking our buildings’ energy savings potential
The central nervous system of our buildings
There are technologies available that have been proven to make our buildings and the systems within them more efficient, yet they are still missing in most buildings. Optimizing technical building systems not only makes building environments more efficient, it empowers building users to better understand their environment – proactively managing their energy usage and maintaining a healthy, comfortable and productive living environment, adjusted to their liking. The cost for these technologies is low and they can be easily retrofitted in buildings, while the energy and cost saving benefits can be remarkable.
Cutting waste and engineering wellbeing for millions of Europeans
The solutions used will vary for different building types but the core principles of reducing waste, cutting cost and improving the environment for the users remain the same. Explore our case studies.
There has never been a better time to start rethinking efficiency

Achieving the EU’s transition to a low-carbon economy by 2050 requires the full decarbonization of our buildings. So, there is a clear need to accelerate the modernization of existing building stock. To achieve this, we need to ensure that technical building systems are operating at maximum efficiency.
Putting Europe on a fast-track to highly efficient, connected buildings
The implementation of the new Energy Performance of Buildings Directive (EPBD) presents an unmissable opportunity for accelerating the optimization of technical building systems and the most cost-effective pathway towards achieving our targets.
The new EPBD reinforces attention to controls of energy flows by getting control basics right, targeting full and part load in inspection requirements and enabling buildings to get smart and put users in control The time to act is now, and there is a set of key measures to make the transition happen.
