New report confirms that Building Automation & Control Systems are absolutely indispensable for the cost-effective decarbonisation of the EU building stock
Specific requirements in the new Energy Performance of Buildings Directive (EPBD) concerning Building Automation and Control Systems (BACS) will ensure that the European Union reduces building energy consumption significantly further and faster than if the Directive was implemented without BACS.
This is the clear message from a study carried out by Waide Strategic Efficiency on behalf of eu.bac, the voice of European manufacturers in the home/building automation sector.
The study demonstrates that the European Commission was correct to add policy measures into the EPBD that target better monitoring and control of building energy systems. It also indicates that every effort must now be made to ensure that these measures are fully implemented.
Why was a recast EPBD necessary?
The recast Energy Performance in Buildings Directive issued in 2018 aims to further improve the energy efficiency of buildings. Its predecessor (the 2010 version) only included rather indirect or ambiguous encouragement to improve building energy performance through better control of technical building systems (space heating, space cooling, sanitary hot water, ventilation and lighting). The revised Directive addresses this deficiency by adding a number of policy measures that target better monitoring and control of building energy systems.
What’s in the study?
This new study by Waide Strategic Efficiency presents a detailed analysis of the expected impacts from the new BACS measures.
It shows that appropriate implementation of the BACS related policy measures will save 14% of total building primary energy consumption by 2050, compared to implementation of the recast EPBD without the BACS measures.
The study also shows that the value of energy savings from the BACS measures exceeds the value of investments by a factor of 9, providing a win-win scenario all round.
The predicted savings also show a noticeably accelerated rate of overall energy savings over that period before the full scale of reductions in building stock consumption from fabric measures come into play.
Results of the study should provide renewed vigour to all those involved or interested in the implementation of the recast EPBD, proving that the new focus on building automation and controls is not window dressing but an overdue acknowledgment of their fundamental importance to the energy efficiency of buildings. Appropriate action by Member States should now follow, with BACS measures contributing significantly to cost-effective decarbonisation of the EU building stock.

And that’s not all!
eu.bac also recently published its guidelines for the transposition of the new Energy Performance of Buildings Directive (EPBD) in Member States.
The new Directive must be transposed into national legislation by 10 March 2020 by Member States and will deliver several key new elements, including:
- Roll-out, by 2025, of BACS functionalities in large non-residential buildings to ensure optimized energy consumption and indoor comfort in real-time, year after year.
- Incentives to BACS functionalities as the most cost-effective approach for maintaining performance of heating and air-conditioning systems in residential buildings.
- Roll-out of individual room temperature control functionality, putting people in control of their energy bills and indoor comfort, and delivering annual energy savings.
- Increased focus on performance improvements under typical, dynamically varying building operating conditions.
These elements have the potential to achieve huge energy and CO2 savings, while empowering users to enhance their comfort and health.
However, to achieve this potential, it is essential that all policymakers know how to smoothly transpose and implement the new requirements – that may look challenging at a first glance.
The aim of the eu.bac guidelines is therefore to provide technical guidance to all the stakeholders involved in the transposition process, in order to turn words into concrete actions.
