  2. The Problem: Fossil Fuel Emissions • Non-Renewable Resources: coal, gas, oil • Combustion of fossil fuels in urban buildings is responsible for approximately half of the global carbon dioxide emissions each year (Beascochea and Filippin, 2005) • Buildings are responsible for about 37% of energy consumed in the United States and consumed 68% of the electricity produced (LEED-NC Reference Guide) • Fossil fuel emissions add carbon dioxide to the atmosphere which increases greenhouse effect and global warming Image taken from: https://ctools.umich.edu/access/content/group/db7fe7ed-e073-46a4-80bc-358b887d9cc9/Lecture%20Powerpoints/George%20Kling/Climate_models_lecture.pdf

  3. Hypothesis • Our case study will examine how we can reduce fossil fuel consumption in the construction and maintenance of a building. • By following the guidelines of sustainable architecture, we will minimize the amount of fossil fuels consumed in the construction and maintenance of a building. • Sustainable architecture attempts to decrease energy use and create buildings that generate their own energy

  4. Sustainable Architecture • Used interchangeably with the term ‘green building’ • Aspects of sustainable architecture (Gissen, 2002): • Energy: redesign mechanical systems to use less energy; use renewable sources (wind, water, solar power) • Light: shading • Air: ventilation • Greenery: use plants to treat water • Water • Waste • Construction : use recycled, local, and renewable materials • Renewable materials: resources that can be replenished at the same rate they are being used Image taken from www.mcgill.ca

  5. Our Building Project Building a visitor’s center in the Nichols Arboretum in order to determine the decrease in CO2 emissions as a result of using sustainable building practices Image taken from: http://www.enfo.ie/leaflets/Sustainable%20Building.htm Sustainable designreduces need for fossil fuels Compare the materials used and energy sources in a green building and a conventional building

  6. Location and Orientation • The orientation of the building within the Arboretum is essential in order to maximize the use of natural energy sources such as the river and the sun: • be built on a hill with the largest side facing south • more windows will be placed on the side of the building with southern exposure, allowing the radiation to enter the building in the winter • deciduous trees on the southern side of the building will shield the visitor’s center from sun in the summertime • ventilation: large vents under the roof of the visitor’s center (Gissen, 2002) • two stories so that it can have a slim shapemaximize ventilation caused by breezes naturally flowing through its windows (Battle, 2002) (Kim, 2005)

  7. Energy Use • Conceptual model of green energy and fossil fuel energy: • Energy used for heating, cooling, and lighting • Green energy: solar and wind • Fossil fuel energy: oil, coal, natural gas • Differences in energy use between conventional and green building • conventional building: uses only .1% green energy (United States Energy, 1998) • green building: uses 75% green energy (LEED-NC Reference Guide)

  8. Types and Amount of Energy Used Conventional building utilizes only .07% solar energy and .04% wind energy (United States Energy, 1998) Green building uses 45% wind energy and 30% solar energy (LEED-NC Reference Guide)

  9. Materials • Conceptual model of types of materials and the resulting pollution during building construction: • Compare local, non-local, renewable, and non-renewable resources • Best source: local and renewableleast fossil fuel emissions and environmental impact

  10. Renewable and Recycled Materials • No standards for recycled or renewable materials in conventional buildings • Use mainly recycled material in green building; 25-80% recycled materials (Hunt, 2002) • Wood is considered to be the most renewable resources: • only 6% used in conventional building (Keoleian, 2000) • According to LEED (leadership in energy and environmental design), at least 50% wood must be used in green building (LEED-NC Reference Guide)

  11. Local versus Non-Local • Local resources: materials that are produced or recovered within 500 miles of a project site • LEED standards require a building to utilize 50% of materials that are extracted or recovered locally and 20% that are manufactured locally (LEED-NC Reference Guide) • By using mostly local materials for construction, the impacts on the environment due to fossil fuel emissions are decreased

  12. Results/Conclusion • our proposed visitor’s center will use energy and materials efficiently • conventional building: • .1% renewable energy (United States Energy, 1998) • non-renewable and non-local materials • sustainable building: • 75% renewable energy (LEED-NC Reference Guide) • recycled and renewable materials • 70% local materials (LEED-NC Reference Guide) • conclusion: the visitor’s center built according to sustainable guidelines will have reduced fossil fuel emissions and have a decreased impact on the environment
