Provide adequate access to daylight, views and outside air to all occupants.

Close proximity of occupied areas to exterior wall, skylights, light wells, atria and courtyards. Correlation of exterior envelope and interior core wall/ service zone.

Consider massing and space planning strategies that include courtyards, atria and light wells, eliminating occupied areas with no access to daylight.

Lower operational cost due to reduced electrical lighting cost, higher performance, less absenteeism sales.

Improved health, greater access to views, daylight, and outside air, higher productivity, less absenteeism, higher profitability, less electrical lighting cost, and higher market appreciation.

Circumstances permitting, use European standards as a model: Full-time occupied office spaces are within 20’-23’ (6 to 7m ) from an exterior window or direct source of daylight.
For central service core office type: Maximum distance between exterior wall and service core wall not to exceed 26’ (8m).
For off-set service cores that share an exterior wall: Maximum building depth for offices not to exceed 65’-72’ (20-22m).
