The Building Automation and Control Systems (BACS) French decree published on 21 July 2020 is planning the fitting of automation and control systems in tertiary buildings by January, 1st, 2025. This will ensure the fulfilment of the energy efficiency requirements defined by the tertiary decree.
This BACS decree, therefore, confirms France’s ambition to make its building stock carbon neutral.
The objectives for reducing energy consumption are identical to those pursued by the tertiary decree, i.e:
- 40% by 2030
- 50% by 2040
- 60% by 2050
Going further with efficiency
More than simply complying with the regulations, the adoption of automation and control systems would allow the centralisation of technical management of buildings, ensuring that all this equipment operates in the most efficient and economical way possible.
In this decree, building automation and control systems mainly concern the management of the main energy-consuming equipment.
However, the use of a water flow analysis system in the buildings should be considered in this context. The installation of this type of device is part of the technical management of the building and allows for significant water savings.
A quick and easy solution
Shayp, an expert in the analysis of water flows in buildings, is thus the perfect tool to implement the decree. By offering services for collecting and analysing water consumption data, the latter is instrumentalized and transformed into an action plan to assist in maintenance decisions.
It is its solution combining a sensor and software that has enabled Shayp to reduce water bills by an average of 22%, thus preserving over 900 million litres of water since its creation. The sensor, a Shayp-designed, Belgian-made POLY4 box, connects directly and non-invasively to the water meter to collect the consumption data with high accuracy. This data is then analysed and reported to the user in a comprehensible and practical way. For that, there is a platform that can be accessed both on mobile or computer (and integrated with any other energy platform). This gives the user a real-time view of the water consumption of the entire building stock and alerts him to any leaks.
In short: what is the BACS decree?
-Who is concerned?
This decree involves both owners and tenants, as it targets all tertiary buildings equipped with technical equipment exceeding a nominal power of 290 kW. Technical equipment means:
- heating, cooling and ventilation of premises
- domestic hot water production,
- integrated lighting,
- building automation and control,
- on-site power generation for a building or building unit,
- or any technical equipment combining several of these systems.
An exemption may be granted to owners who present a study demonstrating that the installation of such a system, or its connection with a technical system, is not feasible with a payback period of fewer than six years.
What are the objectives to achieve?
- To achieve the objectives set by the tertiary decree
- To go beyond the tertiary decree thanks to better management of your consumption
- At the same time, reduce your maintenance costs by detecting operating anomalies
- Increase the added value of the use of the buildings
-What is the protocol to follow and the actions to take?
Regulate the technical systems of your buildings by equipping them with automation and control systems. The measure will be generalised to all tertiary buildings on 1 January 2015.
