Which European standard is associated with indoor environmental input parameters?

The choice of EN 15251 is correct because this European standard is specifically designed to address indoor environmental input parameters, particularly in the context of providing acceptable indoor conditions for occupants. It outlines the criteria related to thermal comfort, air quality, lighting, and acoustic conditions, thereby helping to create healthier and more productive indoor environments.

This standard plays a vital role in informing design strategies that enhance indoor environmental quality, which is a key consideration in sustainable building practices and is aligned with LEED principles. EN 15251 serves as a guideline for assessing indoor environment quality while considering the comfort levels and preferences of building occupants.

The other standards listed do also pertain to different aspects of building environments but do not specifically target the comprehensive input parameters for indoor environmental quality in the same way that EN 15251 does. For instance, EN 13964 focuses on ceiling systems and their effect on acoustic performance, ASHRAE 55 deals with thermal comfort guidelines, and ISO 7708 relates to air quality measurement methods, each serving their respective fields that do not encompass the broader range of indoor environmental inputs that EN 15251 covers.
