Gas Installations Safety and Efficiency:

Essential Elements in Construction Projects

Safety and energy efficiency are crucial components in any construction project. In this context, gas installations play a vital role, being regulated by strict technical standards and regulations that ensure the safety and performance of buildings.

In this article, we will address the key aspects to consider when preparing a gas installation project, highlighting the applicable regulations and providing useful guidance for clients. We emphasize that, as a technical specialty, the gas project must be properly integrated into the architectural project.

Regulations and Legislation for Gas Installations

The regulation of gas installations aims to ensure both the safety of occupants and the structural integrity of buildings. Decree-Law No. 97/2017, dated August 10, establishes the general rules for the design, execution, and maintenance of these installations. This decree defines the responsibilities of the various parties involved, from designers to end-users, making it essential to understand it when developing a project.

Key Points of Decree-Law No. 97/2017:

Classification of buildings: The legislation categorizes buildings based on their use, influencing the specific requirements for gas installations. It is crucial to correctly identify the class of the building to ensure compliance.
Guidelines for design and execution: The decree defines standards for material selection, layout, and installation, promoting safety and energy efficiency.
Inspection and maintenance: Procedures and inspection frequencies are described to ensure the safe operation of installations over time.
Training and certification: Only qualified and certified professionals can execute or inspect gas installations, ensuring compliance with regulations.

Crucial Technical Aspects

The development of a gas installation project requires attention to the following technical factors:

Proper sizing: Correct sizing of components, such as pipes and pressure regulators, is essential to avoid issues such as pressure loss or inadequate pressure.
Effective ventilation: Standards such as NP 1044-1 and NP 1044-2 specify requirements to prevent gas accumulation and ensure adequate ventilation in usage areas.
Equipment placement: Equipment must be installed in easily accessible locations for maintenance, respecting safety requirements and avoiding high-traffic areas.
Certified materials: The use of certified components and materials, in accordance with standards such as NP EN 1057, is mandatory to ensure durability and safety.

Practical Recommendations

If you are planning a construction or renovation project, consider the following practices to ensure a safe and efficient gas installation:

Hire certified professionals: Ensure that the technicians involved have the certifications required by current legislation, such as Decree-Law No. 97/2017.
Anticipate future needs: Plan the project based on both current and future needs, considering potential expansions or changes in gas usage.
Invest in efficient technology: Modern equipment, such as gas water heating systems, offers economically advantageous and energy-efficient options.
Consider sustainability: Opt for solutions that reduce the carbon footprint and promote responsible resource use.

Complementary Legislation for Residential Buildings

In addition to Decree-Law No. 97/2017, other relevant regulations for gas installations in residential buildings include:

Decree-Law No. 11/2023: Allows for the exemption from the gas installation project in buildings that do not use gas appliances, provided it is signed by a qualified technician.
Decree-Law No. 220/2008: Establishes fire safety requirements in buildings, considering the impact of gas installations.
Ordinance No. 386/94: Defines standards for the design, operation, and maintenance of gas distribution networks.
Technical standards (NP): Standards such as NP 1037 and NP EN 12014 provide detailed requirements for ventilation, appliance location, and pipe sizing, ensuring safety and functionality.

Developing gas installation projects is a complex process that requires attention to legal and technical standards. Therefore, hiring qualified professionals and investing in efficient equipment are essential steps to ensure safety, durability, and regulatory compliance.
