In order to achieve Indoor Environmental Quality Credit, Quality Views the project team increased the...

The correct answer isA. Energy and Atmosphere Prerequisite, Minimum Energy Performance. This is because:

Increasing the window-to-wall ratio (WWR) would reduce the solar heat gain and the cooling load of the building, which are two of the main factors that affect the energy performance of a building12.

The WWR is defined as the ratio of the area of windows to the area of external walls in a building3.The higher the WWR, the more natural light and ventilation can be achieved, which can improve the indoor environmental quality (IEQ) and reduce the need for artificial lighting and mechanical systems4.

The LEED AP BD+C V4 credit for IEQ requires thatbuildings have a minimum WWR of 15% for south-facing walls and 20% for north-facing walls5.However, this minimum WWR may not be sufficient to achieve optimal IEQ in hot regions, where high solar radiation and humidity levels create high cooling demand6. Therefore, increasing the WWR beyond these minimum values can help achieve better IEQ by reducing both solar heat gain and cooling load.

The other prerequisites are not impacted by increasing the WWR.Building-level energy metering is a prerequisite that requires measuring and reporting energy use at individual building units or zones5.Fundamental refrigerant management is a prerequisite that requires ensuring proper handling, storage, use, recovery, and disposal of refrigerants used in cooling systems5.Fundamental commissioning and verification is a prerequisite that requires ensuring that all commissioning activities are documented and verified according to LEED standards5.
