THERMAL ACCOUNT 3.0: An Excellent Opportunity for Energy Efficiency Improvements Through BACS Systems

 

The Conto Termico 3.0, or the new Thermal Account Incentive Scheme, supports small-scale interventions aimed at improving energy efficiency and producing thermal energy from renewable sources. It has an annual budget of €900 million, of which €400 million is allocated to Public Administrations.

Main Changes Compared to Thermal Account 2.0:

  • Extension of the range of Public Administrations eligible to access the incentive scheme;
  • Expansion of the technologies eligible for incentives;
  • Increase of the incentive rate up to 100% of eligible expenses for projects carried out on buildings owned and used by municipalities with a population of up to 15,000 inhabitants;

 

 Eligible Beneficiaries (Article 5, Title II)

P.A.: Public Administration
ETS: Third Sector Organizations (Non-Profit Entities)

 

Building Automation Intervention (Article. 5 Title II - Letter f)


The eligible intervention consists of the installation of automatic management and control technologies (Building Automation - BA) for the thermal and electrical systems of existing buildings

The system must comply with the design criteria and functional performance requirements of Class B as defined by the UNI EN ISO 52120-1 standard.

Among the categories of Building Automation (BA) devices related to BACS (Building Automation and Control Systems) and TBM (Technical Building Management) systems are those used to control the following services:

  • Heating and Cooling
  • Ventilation and Air Conditioning
  • Domestic Hot Water (DHW) Production
  • Lighting
  • Integrated Control of Different Applications
  • Diagnostics and Energy Consumption Monitoring.

 

BACS factors

One of the key strengths of BACS systems is the statistical calculation methodology provided and validated by EN ISO 52120-1, which allows an ex-ante estimation of achievable energy savings.

This methodology has been developed at the European level and is referenced by the standard.

Based on the data shown in the table, it can be seen that upgrading a school building from Class D to Class B is expected to result in energy savings of 27>#/strong###, while savings can reach 47>#/strong### in the case of tertiary buildings used as offices.

Eligible Costs and Maximum Limits for Building Automation (BA) Systems:

Supply and installation of the Building Automation and Control System (BACS) aimed at controlling the services included in the building’s energy performance calculation;

- Upgrading of the electrical system and of the winter and summer heating, ventilation and air conditioning (HVAC) systems;

- Professional services related to the implementation of the interventions.


  • Incentive rate:                          40% (*)
  • Maximum eligible cost:             60 €/m²
  • Maximum incentive amount:    100.000 €

(*)  The incentive percentage varies for interventions carried out in the tertiary sector and by Public Administrations.
 


  Specific maximum eligible costs for Public Administration and the Tertiary sector

For Public Administrations, the incentivized percentage of eligible costs is 100% for interventions carried out on:

  • Buildings owned by Municipalities with a population of up to 15,000 inhabitants, used either by the Municipalities themselves or by third parties (provided they are not classified as businesses), for carrying out public and social activities and services of collective interest assigned to the local authority;
  • Public buildings used for school purposes, as well as buildings belonging to hospital facilities and other public healthcare structures, including residential, care, assistance, or long-term care facilities of the National Health Service.



Perry Electric has been designing and manufacturing Class B Building Automation systems in accordance with the UNI EN ISO 52120-1 standard for many years.

A know-how built on thousands of connected apartments, dozens of energy-efficient tertiary and public buildings, and more than 5,000 remotely managed heating plants.

Perry Building Automation systems can be installed in any type of HVAC system, regardless of the heat emitter technology used (radiators, fan coils, radiant systems, etc.).

Communication between the actuators and the field controllers is carried out via radio frequency, providing a high degree of installation flexibility and minimizing wiring requirements.

Each controller is connected to the BACS panel installed in the heating plant room, which manages the entire HVAC system—including boilers, heat pumps, hybrid systems, energy meters, and other equipment—in the most efficient way possible.

The objective is to achieve the desired level of comfort while minimizing energy consumption and overall energy demand.


Through the cloud server, the remote monitoring controllers enable the collection and analysis of operating statuses, energy consumption data, potential malfunctions, and alarm conditions, allowing for efficient and effective remote supervision of the entire infrastructure.
