For the Indoor Environmental Quality Credit, Quality Views, the LEED v4 reference guide specifies that all regularly occupied spaces must be considered when calculating the percentage with Quality Views.
Conference rooms are typically designed for regular occupancy and therefore must be included in the calculation. Spaces like copy rooms and break rooms may not be considered regularly occupied, and lobbies, while they may be occupied, are not spaces where people spend extended periods of time during which they would benefit from quality views.

Indoor Environmental Quality Credit for Quality Views emphasizes the importance of providing occupants with a connection to the natural outdoor environment through window views. This credit specifically targets regularly occupied spaces. Among the options listed, conference rooms are typically considered regularly occupied spaces where occupants spend a significant portion of their time and can benefit from quality views.
In contrast, copy rooms and office building lobbies are not typically areas where occupants spend extended periods, and break rooms, while important, are not always prioritized for external views in the same way that spaces designated for focused work or meetings, like conference rooms, are.References:
