WHAT YOU NEED TO REMEMBER
The BACS decree published in July 2020 completes the tertiary decree. While the latter imposes the achievement of objectives without giving the means to achieve them, the BACS decree imposes the implementation of a system to control energy in tertiary buildings.
Indeed, energy management is one of the most important levers for reducing energy consumption and thus achieving the objectives set by the tertiary decree.
As a reminder, the tertiary sector decree requires all players in the tertiary sector, owners and tenants of buildings of 1,000 m² or more, to reduce their energy consumption by 40% by 2030 as a first step.
The Building Automation and Control Systems decree, known as the “BACS decree”, requires the installation of an automation and control system in buildings, with the aim of monitoring energy consumption and regulating building activities accordingly.
This is a mandatory way of doing so,and it provides a concrete response to the requirements of the tertiary sector decree.
The BACS decree concerns all non-residential tertiary buildings, which have a heating or air conditioning system, whether or not combined with a ventilation system, with a nominal power > 290Kw.
This regulation concerns both new and existing buildings.
An exemption is possible for the latter, by justifying that the installation of the regulation system is not feasible with a return on investment of less than 6 years.
Energy consumption for heating, cooling and ventilation traditionally accounts for 50% of the consumption of a tertiary building.
The objectives of the BACS decree are to
If implemented across the continent, the annual impact in energy savings could reach 20.3% of the total energy consumption of buildings in the European tertiary sector, according to recommendations published by the European Building Automation Control Association (EU.BAC).
To implement a building automation and control system of at least class C according to EN-ISO 52120-1/2022.
To implement a room-by-room control system.
To have a dedicated maintenance contract, carried out by a certified technician.
To record monthly data for five years.
Mandatory for new buildings.
Application for heating or air-conditioning systems, whether or not combined with a ventilation system, with an effective rated output of more than 290 kW.
Application for heating or air-conditioning systems, whether or not combined with a ventilation system, with an effective rated output of more than 70 kW.
