eu.bac System will assure the user a level of performance of their systems, as defined in the relevant EN standards.
The calculation of an expected energy reduction (after improvement) is an estimation based on the efficiency factors from EN 15232 in combination with a weighted calculation model.
The conclusion is that an improvement of 10 points will result in up to a 5% improvement of energy use. The final achievable reduction in the real environment may be different, for instance because of a different user profile, but this calculated value allows at least a rough estimation of the impact of the intended improvements.
The acknowledgement of the audit is the eu.bac System Label that expresses conformity with the EN standards and the eu.bac System Technical Recommendations. It rates the system efficiency and creates trust and transparency to the benefit of building owners and occupants.
The eu.bac System rating will help the building owner and system integrator to assess the energy efficiency of the building automation system that has been installed or is in use and makes it possible to compare it with the requirements specified in the contract.
A building owner, consultant, planer or systems integrator can have a building automation system in a building classified by the eu.bac Audit method.
The classification will help the building owner and system integrator to assess the energy efficiency of the building automation system that has been installed or is in use and makes it possible to compare it with the requirements specified in the contract.
A building owner, who wishes to obtain a eu.bac System Label, contacts an eu.bac authorised auditor. The auditor bears the costs of the building registration when the application is made. The Auditor audits the relevant building and sends the Audit result to eu.bac where ist is verified. After this eu.bac will send the eu.bac System LAbel to the building owner. This can be done for new constructions as well as in already installed systems.
To ensure the correct function of features installed in the BACS and to evaluate the performance of the system, it is required to have a periodic inspection. This normally could be part of an annual maintenance service contract with a service provider that has an affiliation with eu.bac or the original systems integrator
An Auditor is an employee of a Vendor, System Integrator or an Independent Consulting Company. An authorised Auditor is needed to do the eu.bac System Audit.
