SN EN 17037+A1:2022 is a standard published by the European Committee for Standardization (CEN) that focuses on optimizing daylight in buildings. Its applications span across design, construction, and renovation projects to enhance natural light usage and improve interior environments.

Purpose and objectives

The primary aim of SN EN 17037+A1:2022 is to establish guidelines for the effective use of daylight in buildings, thereby enhancing the quality of indoor environments. This standard provides minimum recommendations for daylighting that not only improve occupant comfort but also contribute to energy efficiency. By optimizing natural light, the standard seeks to reduce reliance on artificial lighting, thus lowering energy consumption and supporting sustainable building practices. Overall, the objectives include promoting the psychological and biological benefits of daylight while addressing potential challenges such as glare and summer overheating.

Scope: who must comply

SN EN 17037+A1:2022 applies to a broad range of stakeholders within the construction and building industry, including architects, engineers, building planners, and facility managers. Compliance is essential for projects involving new construction, major renovations, and existing buildings that undergo alterations. Typical industries affected include residential, commercial, and institutional sectors where daylighting plays a critical role in design and occupant well-being. Adhering to these standards ensures that buildings meet not only aesthetic and functional requirements but also regulatory standards for workplace lighting and energy efficiency.

How SN EN 17037+A1:2022 relates to other standards

SN EN 17037+A1:2022 is part of a broader framework of standards that focus on daylighting and energy efficiency in buildings. It is closely related to:

• SN EN 17037:2019: The earlier version of the standard, which laid the groundwork for daylighting guidelines.
• SIA 380/1:2016: This standard addresses energy efficiency in buildings, complementing the daylighting focus of SN EN 17037.
• SIA 180:2014: A standard that outlines indoor climate conditions, which intersects with daylighting strategies for optimal occupant comfort.

Revision history and current status

The SN EN 17037+A1:2022 is the most recent revision of the daylighting standard, officially published by CEN in 2022. This revision includes updates that enhance clarity on compliance requirements and incorporate findings from recent research on daylighting benefits. Changes also reflect advancements in technology and building practices since the previous version, SN EN 17037:2019, ensuring the standard remains relevant and effective in today's building environments.
