Which aspect is NOT a focus of indoor environmental quality in Estidama?

Indoor environmental quality (IEQ) is a critical component of the Estidama sustainability framework, emphasizing the importance of creating healthier and more comfortable indoor environments. The primary focuses of IEQ include aspects like air quality, lighting, and acoustics.

Air quality is fundamental as it relates to the health and comfort of occupants, ensuring that indoor spaces are free from pollutants and provide adequate ventilation. Lighting plays a significant role in promoting well-being, allowing natural light to enhance mood and productivity while also addressing the need for energy-efficient solutions that use artificial lighting wisely. Acoustics are also important, as they affect how sound travels in a space, which can impact comfort and privacy.

Energy efficiency, while vital to overall building sustainability and reducing operational costs, does not fall within the specific category of indoor environmental quality. Instead, it pertains more to the building's performance and resource management. Therefore, when identifying what is NOT a focus area for indoor environmental quality in Estidama, energy efficiency is the correct choice, as it primarily addresses the overarching goals of sustainability rather than the immediate quality of the indoor environment.
