The BACS Decree: Boosting commercial eco-energy through building automation!

The BACS decree, a genuine tool associated with the Eco-Energie Tertiaire scheme, is designed to help building managers/operators achieve the targets set for 2030, 2040 and 2050.

Key points to remember.

What's the background?

Initially published on July 20, 2020 and revised by decree on April 07, 2023, the BACS (Building Automation and Control Systems) decree aims to accelerate the development of building automation and control systems

For whom?

Owners of heating and/or air-conditioning equipment meeting the criteria for liability

Liability criteria ?

Commercial buildings with a heating and/or air-conditioning system with an output of over 70 kW. The obligation applies to the owner of the system in question (whether building owner or tenant).

For thermodynamic equipment (heat pumps, splits, DRV, etc.): heating or cooling capacity of installations exceeding 70 kW;
For joule-effect systems: the maximum power of all electric batteries is taken into account;
For boilers: the sum of the useful outputs of each boiler is taken into account if they serve the same area;
For other systems: each system is considered individually.

What equipment?

HVAC
Domestic hot water
Fixed lighting
On-site power generation
Any other system combining several of the above

What functions should the automation system perform?

Transfer and recording of energy data by functional area
Assessment of the energy efficiency of connected systems and comparison of consumption with reference values (energy audits and equipment data sheets);
Detection of energy efficiency losses (by calculating heating/cooling coefficients of performance that are too low, sudden increases in consumption, inappropriate load curve changes);
Use of open communication protocols enabling communication between all architecture components (supervision, controllers, PLCs, field devices);
Autonomous management of connected technical systems (continued operation in the event of failure).

For when?

For new buildings:
- From the design phase: Buildings with a system rated at more than 290 kW for which planning permission has been granted after 22/07/2021.
- 01/01/2024: Building featuring a system with an output greater than 70 kW and for which the PC was filed after 09/04/2024
For existing buildings :
- 01/01/2025: Building featuring a system with an output greater than 290 kW;
- 01/01/2027: Building featuring a system with an output greater than 70 kW.

How much?

The operation can be partly financed by energy saving certificates (CEE) by meeting class B or class A criteria(BAT-TH-116). This applies to sites not equipped with a BMS, or equipped with a BMS of class C or lower.

A CEE "boost" is also proposed for the installation or upgrading of a BACS by the end of 2023 (bonus in relation to the announced CEE amount).

What control?

Periodic inspection of the BACS must be commissioned by the owner(s) of the system installed:
- Before 01/01/2025 for systems installed before 08/04/2023
- Within two years of installation for systems installed after 08/04/2023 (this may take place at the same time as installation)
The technical inspection must include :
- A literature review to assess the technical state of BACS installations;
- An evaluation of the control/measurement equipment connected to BACS ;
- Recommendations for regulating the implementation and overall operation of the BACS architecture
