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 m 2 ) while the average household ( 家庭 ) has shrunk by 1 person. 1 in 5 new homes is larger than 3,000 sq. ft (279 m 2 )(84 坪 ).

  1. 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.

  2. 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 The Shanghai Tower Teatro Del Agua, Spain – A solar desalination plant

  3. Model of Sustainability (Campbell) Social / Moral / Atheistic Equity Conflict over property Conflict over development Sustainable Development Financial / Market Technical / Design Economy Ecology Energy Conflict over resources Environment

  4. GREEN BUILDING(綠建築) /SUSTAINABILITY BUILDING (永續建築) Practitioners (從業者)of green building often seek to achieve not 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).

  5. Ten of the World’s Most Beautiful Green Buildings Cellophane House EDITT Tower Cathedral of Christ the Light Le Project Triangle Lifepods

  6. AIA/COTE Top Ten Green Projects Every year the AIA (美國建築學會)Committee on the Environment (COTE) invites electronic submission of built projects and award 10 projects designed by AIA members.

  7. AIA/COTE Top Ten Green Projects • 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

  8. More or less technology High-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).

  9. More or less technology 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.

  10. Respect of Tradition – Local Wisdom and Knowledge Renzo Piano Tjibaou Cultural Center, New Caledonia (新喀里多尼亞) 南台平洋澳洲布里斯班東北角 (1998)

  11. 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 .

  12. US RATING SYSTEMS • LEED 2009 • 100 possible base points for 5 categories • 6 points for Innovation in Design • 4 points for Regional Priority.

  13. 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.

  14. 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

  15. Life-Cycle Cost Operating Costs Investment Costs Replacement Cost Replacement Cost First Cost Residual Value Study Period Long or short LIFESPAN – from Planning to Demolition

  16. Long or short LIFESPAN – from Planning to Demolition 0 50 0 50100 B A A

  17. Embedded Energy The energy consumed by all of the processes associated with the production (構築) of a building. - Extract(採掘/提煉) - Manufacture (製造/加工) - Transport (運輸) - Install (安裝) 空間尺寸與材料用量的控制 減少裝修材 使用再生建材或廢棄物
