In buildings, BMS refers to a computer-based system for supervising and controlling various technical equipment. It is capable of managing all solutions used for electrical systems, heating systems, ventilation systems, air conditioning systems, and security. This is known as the implementation of energy efficiency operations.
What is the BAT-TH-116 CEE Fact Sheet for BMS?
The BAT-TH-116 fact sheet is a standardized document that is part of the Energy Savings Certificates, also known as CEEs. This fact sheet encourages the installation of a Building Management System (BMS) in a tertiary sector building.
Here is what the code on this fact sheet signifies:
- BAT refers to the tertiary sector
- TH refers to 'Thermal', encompassing all systems and equipment designed to optimize HVAC (Heating / Ventilation / Air Conditioning) consumption
- 116 refers to the number assigned to the action
In brief, the 'CEE BAT-TH-116' is a fact sheet detailing all terms and eligibility criteria for a 'CEE premium' for the installation of a BMS system covering heating, domestic hot water, lighting, cooling / air conditioning, and auxiliaries.
Calculation and Estimation of Savings with BAT-TH-116
The premium can be calculated using a methodology expressed in cumac kWh.
Calculation Methodology in cumac kWh
The BAT-TH-116 allows for the acquisition of a certain number of cumac kWh.
To determine the exact amount, the following calculation should be performed:
Climatic coefficient x activity correction factor x surface area
The climatic coefficient varies depending on the building's zone. There are three types:
- H1: the coldest zone (Northern and Eastern France).
- H2: the temperate zone (Western and Southern France).
- H3: the warmest zone (only the southernmost part of the country).
As for the activity correction factor, here are the different sectors and their corresponding activity coefficients for heating use only :
- Offices: Fuel 320 and Electricity 190
- Retail: Fuel 340 and Electricity 190
- Education: Fuel 120 and Electricity 73
- Healthcare: Fuel 130 and Electricity 81
- Hospitality / Food Service: Fuel 310 and Electricity 99
- Other: Fuel 120 and Electricity 73
Here are the different sectors and their corresponding activity coefficients for heating and domestic hot water production:
- Offices: Fuel 330 and Electricity 190
- Commercial: Fuel 360 and Electricity 210
- Education: Fuel 140 and Electricity 89
- Healthcare: Fuel 170 and Electricity 130
- Hospitality / Food Service: Fuel 360 and Electricity 150
- Other: Fuel 140 and Electricity 89
Specifically, here is an example calculation and simulation 👇
For example, an office building of 200 square meters, located in Lille, that decides to implement a BMS (Building Management System) connected to an electric heating and hot water production system, will need to apply the following calculation:
1.1 x 190 x 200 = 41,800
This company will therefore be able to generate 41,800 cumac kWh of energy savings.

Technical Details of the CEE BAT-TH-116 Fact Sheet
Eligibility Criteria and Specific Conditions
To benefit from the CEE premium, also known as the energy premium, under the BAT-TH-116 fact sheet, various specific criteria and conditions must be met.
Firstly, the installation of the Building Management System (BMS) must ensure control functions of class A or B for domestic hot water production and heating. Furthermore, these systems and energy efficiency operations must be installed by a qualified professional.
Application Sectors and Practical Examples
The BAT-TH-116 fact sheet only applies to existing tertiary sector buildings.
Let's take the example of installing a new Class A BMS that regulates the heating, air conditioning, refrigeration, and domestic hot water (DHW) of a shopping center. The cost of these energy efficiency operations will amount to 120,000 euros.
The CEE premium with bonus could finance the project up to 91,740 euros. Thus, only 28,260 euros would remain payable by the client.
Financing and Bonuses for BMS Projects via CEEs
The BAT-TH-116 fact sheet enables the financing of BMS projects.
Financial Aid and Incentives
ESCs are state-regulated certificates. This mechanism obliges energy suppliers to incentivize individuals, businesses, and public entities to implement BMS.
Indeed, Energy Savings Certificates set objectives for them to encourage energy consumers to implement a system and energy efficiency measures.
ESCs Application and Acquisition Process
To qualify for the incentive, an application must be compiled and submitted to an energy supplier or partner.
Certain specialized delegated entities offer comprehensive solutions that notably include technical and energy audits.
Impact of BMS on Energy Performance
BMS has a significant impact on a facility's energy performance.
Case Studies and Feedback
BMS contribute to reducing energy consumption. For instance, they are fully capable of controlling lighting systems by turning off lights in unoccupied rooms and adjusting light intensity based on natural light levels.
Companies that have implemented this lighting control have observed a reduction in their consumption, resulting in significant energy savings and extended lifespan for their light bulbs.
Role of BMS in Improving Energy Efficiency
A Building Management System (BMS) helps reduce energy consumption through building automation systems. These systems provide solutions and positively impact the energy consumption of industrial and commercial buildings. This consequently reduces energy waste and enhances occupant comfort.
Compliance with the BACS Decree and Other Regulations
The BAT-TH-116 standard must comply with certain regulations, including the BACS decree.
Implications of the BACS Decree for BMS
The BACS decree aims to pursue the state's objectives for reducing energy consumption in the tertiary sector.
As of January 1, 2025, this decree mandates the installation of a BMS (a building automation and control system) in existing buildings used for tertiary activities and equipped with a heating or air conditioning system with a nominal useful power exceeding 290kW.
As of January 1, 2027, the buildings subject to this regulation will be those with a nominal useful power threshold above 70kW.
This decree also mandates the maintenance and inspection of automation and control systems.
Other Relevant Standards and Regulations
The EN 15232 standard specifies the requirements for energy-efficient Building Management Systems. It thus includes an ordered list of control automation functions.
Furthermore, it includes a guide to best practices for BMS newcomers. Finally, it specifies that demand-based control is essential to achieve the highest energy class, namely Class A.
