Mandatory inspections of technical systems in buildings

Technical systems (e.g. air conditioning, domestic hot water, etc.) installed in commercial and service buildings are subject to mandatory periodic inspections. This requirement is laid down in Article 15 of Decree-Law No. 101-D/2020, which came into force on 1 July 2024. The main objective of these inspections is to assess the operation of these systems and identify specific measures to optimise their operation, in terms of both their functional performance and their energy consumption.

Which technical systems are covered?

This requirement applies to the following types of technical systems: chillers, boilers, heat pumps, rooftop units, VRV units, solar thermal systems and building automation and control systems (BACS). This requirement applies only to systems with a rated power output of over 70 kW.

Frequency:

  • The audit is carried out every four years on all equipment with a power rating between 70 kW and 250 kW. For equipment with a power rating above 250 kW, the audit is carried out every two years.

Scope:

  • The inspections focus on the operating, monitoring and maintenance conditions of the technical systems concerned.

Report:

  • TDGI issues a report setting out all the findings of the audit carried out, as well as recommendations for rectifying any anomalies detected. This report is provided to the client, and a copy is also sent to ADENE in accordance with the legal requirement.

Apart from complying with legal requirements, are there any other benefits?

Yes. During inspections of air-conditioning systems, measurements are taken to assess in detail the actual operating conditions of the technical systems. This makes it possible to identify potential areas for improvement in the energy efficiency and functionality of the equipment, thereby yielding tangible financial benefits and helping to prevent future operational failures.
