Green Architecture

Sustainability
1. Water recycling
  1. Water-Saving appliances (shower heads, ultra-low-flush toilets etc.)
2. Sustainability is the endurance of biological systems and processes (remaining productive indefinitely)
3. Technologies supporting sustainable energy include renewable energy sources e.g. hydropower, solar energy, wind energy, geothermal energy, bioenergy, and technologies designed for improving energy efficiency
Environmental issues
1. Green architecture reduces the amount of green house gas emissions produced by over energy consumption within the home often caused by the use of man-made heating and cooling instead of designing the house passively.
Renewable energy
1. Bioenergy
  1. Wood waste
  2. Landfill gas
  3. Municipal solid waste
    1. Paper / cardboard
    2. Food scraps
    3. Organic matter (leaves, grass clippings, wood etc.)
  4. Bagasse (remaining after sugar is extracted from sugarcane)
2. Solar energy
  1. Solar panels / photovoltaic panels
    1. Installed on rooftops or as stand alone
3. Wind energy
  1. Wind turbines
4. Geothermal energy
  1. Is a clean, energy efficient way of heating / cooling a home
  2. No need for boilers and man-made heaters
5. Reduces Greenhouse Gas Emissions
Global warming and its effects
1. Global warming is the gradual heating of the earth's surface, atmosphere and waters which will have sever consequences on the earth and species of plants and animals if not reduced
2. Ice and glaciers melting worldwide
3. Certain species of animals and plants have moved to different locations where it is cooler (further North)
  1. some species of animals have declined while some have increased such as the Spruce Bark Beetle which has eaten approximately 4 million acres of spruce trees
4. increasingly warm temperatures
5. Increasing rise in sea levels
6. Preciptation in the form of rain and snow, has increased worldwide
7. Caused by human's burning of fossil fuels that pump carbon dioxide, methane and other greenhouse gases into the atmosphere creating a global heating effect
Ecological concepts
1. Residential
  1. Cabin
  2. Tiny house (popular trend)
  3. Transporter
    1. Travellers
    2. Used by construction workers on worksites
  4. Pre-designed homes
    1. Already council approved design
      1. Saves time in overall design and build process
    2. House and land package
  5. Standard (one place for a lifetime)
  6. Pod
  7. Floating
    1. Built into / onto riverbank
      1. Use of dolphins / pylons
    2. House boat
  8. Prefabricated
    1. Only takes a few days to construct
    2. Can be imported, moved and constructed easily
Architectural aesthetics
1. Materials
  1. Used for finishings
    1. Sustainable
    2. Recycled
      1. Plastic bottles recycled into roof tiles
      2. Stone / metal
    3. Eco-friendly
      1. Paints
        Natural paints
        More expensive than standard
        Healthier for humans and life
        Liquid pigments
        Least amount of processing
        Zero-VOC (Volatile organic compounds)
        Some VOCs are toxic and dangerous to humans as they leech into the air at room temperature
      2. Lime wash
  2. Used for construction
    1. Recycled
      1. Timbercrete
      2. Newspaper insulation
      3. Reclaimed materials (brick, wood etc.)
    2. Double glazed / Triple glazed windows
    3. Sustainable
      1. Bamboo
        Variety of different species some of which are not appropriate for construction. Guada bamboo is the most appropriate for construction.
        Guada bamboo stronger than concrete and approximately same tensile strength of steel
        Many fast growing species therefore extremely sustainable due to some species growing approximately 90cm per day. (Quick to replenish)
    4. Eco-friendly
      1. Mud brick
      2. Rammed earth
      3. Cob
      4. Straw bales
        They act as a thick insulative
      5. Screed
        Used for flooring foundation
      6. Gravel
      7. Chalk
      8. Sheep wool insulation
      9. Green roof (can grow native plants etc.)
      10. Cork
Designer's role
1. Designing to clients needs
  1. Suited to different family sizes
  2. Design for disability access
  3. Designing with clients style (working with likes and dislikes)
2. Environment
  1. Working with natural elements onsite / landscape
    1. Shading of trees
  2. Design suited to different climates
    1. Adelaide Hills
3. Disadvantages of designing green architecture
  1. Certain sustainable, eco friendly materials need may not be accessible
  2. The building may not be able to be orientated a certain way in order to create a passive design, due to the landscape or plot layout
  3. Climate may not be permitting of certain materials or design
4. Advantages of designing green architecture
  1. No need for heating and cooling due to effective passive design
  2. Cost effective over lifetime of building compared to standard non-green architecture
  3. Effective indoor air ventilation either created through passive, natural or mechanical design creates a healthy indoor environment for occupants especially those with asthma
  4. Reduces energy consumption
Environmentally friendly
1. The use of materials, products, construction methods and practises that don't effect / create little harm and negative impact on the environment / ecosystems
  1. Non-toxic materials such as natural paints
Green energy
1. Recycling
  1. Composting
2. Water management
  1. Use of grey water
  2. Use of bore water
3. Solar energy
4. Carbon positive
  1. Produces more energy than is needed to run the house
Passive design
1. Orientation
  1. good orientation reduces even eliminates need for auxiliary heating / cooling
    1. Reduced energy bills
    2. Reduced Greenhouse Gas Emissions
    3. Improved comfort
  2. Adelaide Hills
    1. Zone 6 climate
      1. Space zoning
        Private spaces
        Nightly spaces
        Living spaces
        Common spaces / daily spaces
        Within range 15°W–20°E of True North (although 20°W–30°E of True North is acceptable)
        Allows verandah / eaves to shade summer sun out to keep home cool while allowing winter sun in to heat up home
2. Comfort zones
  1. Cross ventilation
  2. Natural heating and cooling using the winter and summer sun and shading of trees and objects
3. Energy efficieny
  1. Ratings
    1. House design must meet at least 5 or 6 stars depending on location and size of house
    2. Rating types may vary depending on country and Government regulations
    3. natHERS
