COMMUNITY hospital @ yishun SINGAPORE
A PUBLIC PLAZA seamlessly
integrates patient services with the surrounding neighborhood - creating a verdant and flexible space where patients and the community coalesce with each other and the natural environment
THE COMPOSITION of the building tells the story of a community hospital designed for active participation

WATER COLLECTION - concave roof collects, filters and heats rainwater used for irrigation and grey water
Solar collection area on roof - surface temperature averages around 110 during day time
The building has been designed as a por porosity is intended to promote the move and the penetration of light. The wards, stations, and supporting circulation path arranged around a central spine. The in the wards and the circulation spine crea exhaust airshafts. The shafts have been 4 to 6 air changes per hour in each ward smoke dampers are assumed to be locat opening of each shaft for purposes of lif proposed design includes a large roof c spans over the wards and central circula
This roof canopy contains voids in the st between the top and lower surfaces. Th connected to the wards’ vertical exhaus the sun heats the top surface of the roof heat is transferred to the air in the canop heats the air which causes it to become rises up to the roof cavity to an exhaust escapes, inducing a draw through the ve stacks connecting the canopy to the war
Supplemental exhaust fans
Should there be insufficient solar gain o induce buoyancy and achieve the desire exchanges during all weather conditions to augment natural wind and buoyancy f supplementary dedicated extract fans w air flow in the shafts fall below 4 air chan The control of these fans is automatic an volume flow in the shafts.
This fan-assisted ventilation strategy wil number of hours when internal comfort met. This includes periods when it is no meet these conditions due to restricted caused by low external wind speeds (0-7 during periods of heavy rainfall when th need to be closed to avoid water damage

To reduce the impact of driving rain it is slow down the wind speed carrying the r accomplished by adjusting the spacing o in the shutters and screens mounted nex elements and doors. The large canopy a balconies also assist in reducing wind sp impact of the wind driven rain.
Ceiling fans circulate air in spaces to promote cooling by increasing air speed
NATURAL CONVECTION - as roof heats air is drawn from wards reducing risk of contamination
