An optimised energy use of Technical Building Systems (TBS) could yield significant energy savings and emissions reductions. A new study by Ecofys estimates an additional annual CO2 reduction potential of roughly 60 Megatonnes by 2030 compared to business-as-usual, just by consistent basic optimisation of TBS in existing buildings across the EU.
TBS are the technical equipment for heating, cooling, ventilation, hot water, lighting or for a combination thereof, of a building or building unit. The report has investigated how much an optimisation of the energy use of TBS could contribute to closing the gap between the current rate and depth of energy efficiency improvements and the proposed binding energy efficiency target of 30 % by 2030.
Next to the projected energy savings and emissions reductions, TBS could also offer additional flexibility options. Through advanced Building Automation and Control Systems (BACS), they could become an active, manageable part of the energy system in transition. In the current study, the experts also include policy recommendations on how to unleash the TBS savings potential.
