eu.bac publishes BACS reference case booklet

Today eu.bac is publishing a collection of building automation and control system (BACS) retrofit reference cases. This booklet showcases a variety of projects across Europe, which demonstrate the cost-effectiveness and added value of concrete BACS retrofits.  

Under the current BACS requirements according to the Energy Performance of Buildings Directive (EPBD) building automation and control functionalities have to be present in all large non-residential buildings by 2025. As demonstrated by the Waide study this could lead to savings corresponding to 14% of the total building energy consumption, with 64 Mt CO2 annual savings and €36 billion energy bill savings. To help understand the saving potential in different use cases, this booklet brings together projects from various sectors like education, hospitality, recreation and residential. BACS can reduce energy consumption by up to 52 % in offices and lecture halls, 26% in educational institutions and hospitals, 41% in hotels and restaurants, 49% in wholesale and retail buildings and 27% in residential. Moreover, these technologies are a capital-light investment on average at  € 28,7 per m2 with payback times of around 3 years. In addition to the energy savings, BACS provide building users with comfort, and healthier environments and make the building futureproof.

This booklet helps decision-makers understand the added value of implementing ambitious BACS requirements for the whole building stock. Meanwhile the eu.bac Guidelines on the transposition of the EPBD together with the EPBD BACS compliance verification checklist provide technical advice to all stakeholders involved in the transposition process.
