Khoo Teck Puat Hospital
Location: Yishun, Singapore
While all kinds of spaces inhabited by human beings - from offices to high-rise apartment buildings - can benefit from biophilic design, hospitals, where biophilic design is perhaps most urgently needed, are often as far from nature as it's possible to get in a man-made space. Cost is often cited as a reason - or an excuse - for this. However, there are exceptions, notably the Khoo Teck Puat Hospital, which serves the healthcare needs of more than 700,000 people living and working in the north of Singapore.
Overlooking the scenic Yishun Pond, the Khoo Teck Puat Hospital is designed to be patient-friendly. The 10-bed C-class wards is divided into two sections, each with its own toilet and shower facilities. There is only one drop-off point for the hospital and the distance from it to the emergency department is only 20 metres, while the distance to the specialist clinics is between 20 and 40 metres. There are no protruding sinks or cupboards in the wards so patients are less likely to hurt themselves.
Fins along the building's walls are designed to channel the prevailing north-east winds into the building. Wind tunnel tests conducted at the National University of Singapore found that these fins would enhance the airflow by 20 to 30 per cent. Sunshades over the windows protect patients from the direct glare of sunlight. The shades also re-direct light towards the ceiling to enhance the brightness of the wards and save energy. Large fans in public areas are powered by solar panels on the roof. The air-conditioning system draws supply air from its internal courtyards, where the air is cooler, thus reducing the cooling loads.
