Why system sizing determines system performance

Inappropriate sizing can compromise the effectiveness of a fire safety system, result in noncompliance, or lead to significant additional costs.

Studies and technical design make it possible to:

  • adapt the systems to the site’s actual level of risk
  • ensure compliance with regulations and standards
  • ensure expected performance during an incident
  • avoid unnecessary oversizing
  • anticipate operational and maintenance constraints

This phase directly affects the reliability and longevity of the installations.

DEF: a rigorous and contextualized approach

DEF relies on engineering approaches grounded in a thorough understanding of the site, its uses, and the associated risks.

Our role is to:

  • analyse technical and regulatory data
  • translate the requirements into design parameters
  • ensure the overall consistency of the systems
  • validate technical decisions before implementing them

A methodical approach focused on reliability and operations.

What the studies and technical sizing entail

The design and technical specifications are tailored to each project.
Nevertheless, they are based on a common structure that ensures accuracy, compliance, and performance.

Risk and assumption analysis

Consideration of risk scenarios, site uses, and site constraints

Definition of technical parameters

Identification of the characteristics necessary for the proper functioning of the systems.

Calculations and verifications

Performance of the calculations necessary for the design of the systems.

Regulatory and standardisation integration

Compliance with applicable regulatory requirements and standards.

System consistency

Verification of compatibility and interaction between different devices.

Validation of technical decisions

Ensuring that the selected options are finalised before they are implemented.

technique analyse

Studies tailored to all types of projects

DEF conducts studies and technical design work for:

  • new construction or renovations
  • industrial, commercial, and logistics sites
  • public access and high-rise buildings
  • simple or complex projects
  • single-site or multi-site environments

Each study is conducted with the project’s specific constraints in mind.
