The design of the Tampines GreenJade features a distinctive take on public housing through the introduction of Cool Flats Typology. through modular design and the utilization of standardised Pre-finished prefabricated Volumetric Construction (PPVC) modules. The project takes on special considerations, as a precinct inspired by its surrounding of nature, and aims to harness passive cooling strategies as part of the strive towards greater sustainability.

The objective for the precinct design is to harness the essence of being close to greenery and water; and to create a liveable environment with distinctive features. The strive and considerations for sustainability is a holistic one, as summarized through the design of a Cool Precinct with Cool Design for Cool Living in Cool Spaces.
Cool Design: In Tampines GreenJade, through modular design and the utilization of standardised PPVC modules across different unit types, variegated stacking of different unit types is enabled – allowing a distinct block form with void openings. The outcome of ambitious modular design is the breakthrough in standardized modules which can be used across different unit types, thereby allowing further replication and efficiency in construction.
Considerations are holistic and the void openings created, other than providing a distinct architectural expression, would also allow improved wind flow and ventilation through the precinct and even residential units; all while working within the premise of PPVC design and construction.
Cool Living: In theme with sustainability outcomes, the spaces within the precinct are designed with passive cooling strategies in mind. Unit design aims to enhance thermal comfort with service areas at East/West facing façade for heat avoidance, and void openings created at building facades allow for increased ventilation and potential further cooling. Units in the precinct feature balconies and mid-height top-hung windows (“monsoon windows”) for further enhancement to good natural ventilation.
CFD wind flow analysis was carried out during the design of the precinct to ensure effective natural ventilation using the design strategy. The void openings also function as urban gateways, where the residential blocks are connected via link bridges to the roof garden atop the MSCP.
Cool Spaces: Through considerate site planning and design, the precinct strives to create a sustainable environment for Health and Wellness of the residents. On the ground, the layout of the Community Spine and block clusters encourage social interactions in a lush and green setting. In mid-level, void openings are designed as Urban Gateways connecting all blocks to mid-level roof gardens, where designs feature Biophilic strategies and nature-inspired elements and water features.
Community spaces created adjacent to greenery aims for greater social inclusivity. Residents are able to access their block clusters via sheltered connections, with an open sided community lawn and with Community Living Rooms in heart of each block cluster – which provides an intimate setting for incidental meetings, and spaces as affordances toward the growth of a close-knit community.
