Compliance of technical-construction choices with the EPB study

In the context of contemporary construction, energy sustainability is no longer an option—it’s a requirement.

The EPB study (Energy Performance of Buildings) is a fundamental tool to ensure that every building meets the energy standards imposed by current regulations. But what does this study really entail? And how does it influence technical-construction choices?

The EPB study is a mandatory technical analysis that evaluates the energy performance of a building, both during the design and construction phases. Its purpose is to verify that the property meets minimum requirements for energy efficiency, CO₂ emissions, and indoor comfort, in accordance with European directives and regional regulations.

The EPB study considers a wide range of technical-construction parameters, including:

• Construction materials: Must have adequate thermal properties (transmittance, thermal mass, etc.).

• Thickness and type of insulation: Thermal insulation is crucial to reduce energy loss. The EPB study defines the minimum required thicknesses for walls, roofs, and floors.

• Windows and doors: Evaluated based on thermal transmittance (Uw), airtightness, and orientation. The glass transmittance (Ug) is also included in the calculation.

• Ventilation: Controlled air exchange must be ensured. This can be achieved through fully mechanical ventilation (System D) or a combination of mechanical and natural ventilation (System C).

• Systems and installations: Includes heating, cooling, domestic hot water production, lighting, and, if present, photovoltaic or solar thermal systems.

Every design choice directly impacts the EPB score and, therefore, the building’s compliance.

The architect plays a key role in ensuring EPB compliance:

• Project coordination: Must integrate EPB requirements from the earliest design stages, collaborating with engineers and energy consultants.

• Informed choices: Every material, construction detail, and system solution must be carefully selected, balancing aesthetics, functionality, and energy performance.

• Documentation and communication: The architect is responsible for correctly transmitting data to the EPB consultant and adapting the project to any regulatory changes.

  
  

The EPB study is not just a regulatory obligation—it’s an opportunity to design buildings that are more efficient, comfortable, and sustainable.

Compliance with EPB through technical-construction choices is the result of an integrated process, where every decision matters.

And in this process, the architect is the conductor who orchestrates technique, regulations, and design vision.
