Sustainability Sustainable development Has been defined as the development that meets the needs of the present without compromising the ability of future generations to meet their needs.

Sustainable housing is important in order to ensure a balanced consideration of social, environment and economic needs in the housing development sector. 

  

Successful – a strong partnership between all players in the development is a must.

Should NOT be just government’s agenda, but Supported by all industry players, including: Architects, planners, developers as well as the society.

Sustainable Development means‌ Economic Success for the Future

Calm, Quality Social Developments

Apartment:Aesthetic, Healthy Environment

Achieving

Sustainability through Passive Strategies:

Active Strategies

Lush Greenery at level 1 & 3 • Energy Efficient Air-conditioners • Energy Efficient Lighting • LIFTS – VVVF & Sleep Mode • Motion Sensors For staircase – half-landing, lift lobbies & common areas • Gas heaters • Heat Recovery devices • Monitor the water Usage through Submeters

Efficient façade Design for Effective Shading through • Balconies • Bay Windows • AC Ledges High performance Glazing with “Better SC and UValue” Comfortable Indoor NOISE levels through Deep Balconies Ample Daylight for indoor

Disruption of a Green Apartment 

 





Architecture education should focus on imagination, creativity and teamwork only Teach music, sports and arts Music and arts to help our architects to be more creativity and imaginative Sports to make our architects know what is teamwork The future on a Green Apartment is not about competition of knowledge

 BUT,

wisdom and experience
