Woodlands Hospital integrates nature, daylight, artwork and wayfinding features to create a visually engaging environment that supports healing, comfort and well-being

Measured Daylight & Illuminance

Spot illuminance measurements were taken across 20 indoor, outdoor, shaded and window-adjacent locations during a single-morning site visit on 28 Aug 2026. Average illuminance across the 20 measurement records ranged from 49.7 lx at the Learning Space Lobby to 15,797 lx in direct outdoor sunlight.

Qualitative Visual Observations

Qualitatively, glare was more noticeable in areas exposed to direct sunlight and at window-adjacent locations with strong daylight penetration, while shaded and deeper internal spaces generally experienced less apparent glare. These observations were based on the visual walkthrough rather than occupant surveys or instrument-based glare assessment. No direct glare metric, such as Daylight Glare Probability (DGP), was measured on site.

Design context: daylight and shading

The project’s Green Mark information describes a design approach that places offices and clinics along the building perimeter to bring daylight into work spaces. It also says window position and orientation, selected glazing, and facade shading were intended to admit daylight while limiting heat gain. These are documented design strategies, not results of our site measurements.

Location review

The 20 measurement values come from the workbook. The floor plans are the supplied Woodlands Hospital maps. Tower B TIM Café points appear on the campus view; the Level 1 and Level 5 plans focus on the Medical Centre. Marker positions are group-reviewed approximations, not surveyed coordinates. The campus overview has south at the top; the Level 1 and Level 5 plans retain north at the top.

Overall evaluation

Overall, illuminance varied considerably across the surveyed locations. Window-adjacent and perimeter spaces generally recorded higher values, while some deeper internal spaces recorded much lower levels. The shading comparison also showed a large difference between direct sunlight and shaded outdoor conditions. Because all measurements were collected during a single morning visit and sequentially rather than simultaneously, the results should be interpreted as a snapshot of observed conditions rather than a complete annual daylight assessment.
