BCA Greenmark Launched in 2005

Maximising the potential cost effective energy savings with sustainable designs

Its national target is to achieve “greening” 80% of our buildings by 2030

*BCA: Building and Construction Authority

Evaluating Current Measures

BCA Greenmark scheme assesses buildings for:1. Energy efficiency

2. Water efficiency

3. Environmental protection

4. Indoor environmental quality

5. Other green features and innovations

Evaluating Current Measures

Exploring New Measures

Cons - Creates hazards such as:

1. Radioactive waste2. Usage to create nuclear weapons3. Threat of criticality accidents, loss-of-

coolant accidents, nuclear fuel response to reactor accidents, nuclear meltdown

Fukushima Daiichi nuclear disaster

Exploring New Measures

Geological repositories Radioactive waste must be contained &

isolated

Current waste disposal methods: Storage above ground in pools of water Recycling & reprocessing spent fuel

Exploring New Measures

Geological repositories Underground engineered facilities

Reduces risk of released radioactive waste

Exploring New Measures

Underground/ Underwater Nuclear plants Underground Ammo facility (opened in 2008)

Jurong Underground Caverns (set to open in 2015)

Advances in technology brings about nuclear safety

Exploring New Measures

Individual efforts

Solar Panels

Roof Sunlight

Rain Gutter System

Green Concrete

Exploring New Measures

The Haus@Serangoon Gardens

Individual efforts

Conserve use of electricity

Cut back on meat (one-fifth of global emissions come from livestock)

Use energy-efficient appliances
