Passive Design for Environmental Comfort Passive design improves comfort by working with natural environmental conditions and forms an important part of our building design approach. Design Feature Purpose Application Building orientation and facade shading Reduce solar heat gain and improve thermal comfort Incorporated in Tropicana Gardens Office Tower (GBI Silver certified) and applied in selected residential developments. Natural ventilation Improve airflow and indoor comfort Applied in common areas across residential and mixed-use developments through building layout and design. Daylight optimisation Support natural lighting and indoor comfort Integrated through façade design, window placement and building layout planning. Landscape and water features Improve microclimate and reduce heat build-up Implemented in Tropicana Aman and Tropicana Metropark townships through parks, lakes and landscaped areas. Thermal insulation and glazing Improve indoor temperature stability Low-emissivity glass and insulation used in selected developments to enhance building performance. Climate-responsive building envelope Reduce heat transfer and improve building performance Building façade design, shading devices and material selection are considered to support environmental comfort in selected developments. For landed residential developments, passive design considerations such as building orientation, roof insulation and ventilation design are also incorporated in selected homes to improve indoor comfort and long-term liveability. These measures support comfortable indoor environments and long-term building performance. Active Environmental Systems & Sustainable Infrastructure Active systems are incorporated during design and development to support efficient building operation and future-ready infrastructure. Feature Purpose Examples LED lighting and smart lighting controls Support efficient lighting design and reduce unnecessary energy use Installed across offices and incorporated into new developments where appropriate. Building Management Systems Enable coordinated monitoring and management of building systems to support efficient operation Used at Tropicana Gardens Office Tower and incorporated in selected commercial developments. Solar photovoltaic readiness Support future renewable energy adoption and flexibility for residents Eco-Series homes at Tropicana Aman offer provision for solar photovoltaic integration and installed at our construction site for temporary access at Tropicana Twinpines. Smart meters Enable monitoring of utility usage where applicable and support efficient resource management Installed in all our new development as part of building system design.
