Healthcare Design - September 2017 - 44

The naturally ventilated design also eliminates mechanical cooling requirements for
70 percent of the building, allowing the hospital
to install smaller cooling towers. The towers use
a specially treated grey water and air handling
unit condensate for their water needs, a process
that enables more cycles of water reuse. "So not
only does the cooling tower use reclaimed water,
it's able to use the water more effectively than
conventional city water," Baum says.

The campus' other conservation strategies include water-efficient
plumbing fixtures and a rainwater capture system to help irrigate the extensive landscaping on-site. The facilities don't need too much rainwater
due to the tremendous rainfall in Singapore (an average of 91 inches per
year), but irrigation ensures that the plantings, particularly on the building, remain green. In addition, sub-meters and leak detection facilitate
monitoring, maintenance, and control of the cooling tower, toilets, and
irrigation system, leading to less water waste.
A LESSON FOR ALL

After two years of operation, the wards' ventilation performance is getting high marks from users. Based on patient and staff surveys, which
were conducted in March 2016 after nine months in use, the average
indoor temperature of 84.5 degrees Fahrenheit was accepted by 93 percent of surveyed users and the average relative humidity of 63.7 percent was considered comfortable by 90 percent. In addition, 80 percent
reported that the lighting levels are "just right" with a good amount of
natural daylight, 90 percent of the patients interviewed agree that the
ward design has helped them recover, and 90 percent of the staff state
that the ward design has helped them become more productive in their
work.
Could it be an example worth following for hospitals around the world?
Jury members for the COTE Top Ten Awards think so, describing the project as an "extraordinary model for hospitals to behave as healing environments, not seen in the United States. The passive strategies demonstrated
here are a model for hospitals around the world."

eco-friendly design
features natural ventilation,
daylighting, photovoltaics,
solar thermal collectors,
rainwater collection, and a
grey water system. BELOW:
Unlike a traditional linear
ward layout, a fan-shaped
design creates the space
next to each bed for
patients to have individual
windows.
