2011 S 展演空間導論 – 永續性

CONSUMPTION GROWTH – Taking the House Market Since 1950 in the US for Example

• The average new house ( 新建獨立住宅 ) has increased by 1,247 sq. ft (116 m2) while the average household ( 家庭 ) has shrunk by 1 person.

• 1 in 5 new homes is larger than 3,000 sq. ft (279 m2)(84 坪 ).

• 88% of American commuters ( 通勤族 ) drive to work and 76% of those drivers commute alone. (250 million registered cars in the US.)

• 1 in 2 homes has 2.5 baths or more.

• People who live in cities use half as much energy as suburbanites.


OUR MISSION• The global building sector

needs to cut energy consumption in buildings ( 減少能源使用 ) 60 % BY 2050 to help meet global climate change targets.

• Means to achieve the goal- 節流 Passively ( 被動 ):

Conserve ( 節省 ) energy use and improve efficiency ( 效能 )

- 開源 Actively ( 主動 ): On-site, distributed renewable energy generation

GREEN BUILDING (綠建築 ) /SUSTAINABILITY BUILDING (永續建築 ) • Practitioners (從業者 ) of green building often seek to achieve no

t only ecological but AESTHETIC HARMONY between a structure and its surrounding (natural or built) environment.

• The appearance and style of sustainable homes and buildings CAN BE NEARLY INDISTINGUISHABLE (無法辨認的 ) from their less sustainable counter-parts (對照 ).

AIA/COTE 10 Measures of Sustainable Design

- Sustainable Design Intent & Innovation

- Regional/Community Design & Connectivity

- Land Use & Site Ecology

- Bioclimatic Design

- Light & Air

- Water Cycle

- Energy Flows & Energy Future

- Materials, Building Envelope, & Construction

- Long Life, Loose Fit

- Collective Wisdom & Feedback Loops


MORE OR LESS TECHNOLOGYHigh-Tech Approach ( Rogers, Foster, Hopkins, Grimshaw)

– Emerged in the 70’s.

– A technical driven approach but was however an architectural style

– Emphasizing structure and advance technology

– Efficient construction process ( 有效率的構築過程 : 模組化 ).


Low-tech Approach– Recycling of materials and components

– Traditional construction, insulation, and natural means of heating and ventilation.

– More to poverty-stricken areas.

– Use more local labors that provide job oppertunities.

– Might involve the use of human wastes to generate energy and nutrient for the soil.

GREEN BUILDING

• INCREASING THE EFFICIENCY with which buildings and their sites use and harvest

– energy,

– water,

– materials.

• REDUCING BUILDING IMPACTS on human health and the environment, through the complete building life cycle

– siting,

– design,

– construction,

– Operation and maintenance

– removal .


LEED 2009 • 100 possible

base points for 5 categories

• 6 points for Innovation in Design

• 4 points for Regional Priority.

US RATING SYSTEMS


TAIWAN RATING SYSTEMS

• EEWH (Ecology, energy conservation, waste reduction and health) • 100 possible base points • Comprises 9 indicators that fall into 4 categories

– Water soil content (infiltration and retention)– Energy savings (for the building envelope, lighting and HVAC)– CO2 emissions reduction– Construction waste reduction– Water conservation– Garbage and sewage improvements– Biodiversity– Indoor environmental quality.


SUSTAINED ECOLOGY SYSTEM

Biodiversity ( 生態多樣性 )

- The degree of variation of life forms within a given ecosystem.

- Greater biodiversity implies greater health of the ecosystem.

Urban planting should encourage

- Biodiversity

- Native species ( 原生 )

- Continuation of green spaces
