Some of the big goals I would like to consider for my design are: energy efficiency, water conservation and transgenerational structure. To achieve these goals I have some target goals for my design.

Goal 1: Site EUI reduction

Ideally, every year the building should generate as much energy as it uses.

  • Measure:  The site energy usage intensity is measured in kBtu/ft²/yr
  • Targets:
    • minimally acceptable value: Achieve 80% EUI reduction compared to similar buildings in the area or 20% of 84.3 kBtu/ft²/yr = 16.86 kBtu/ft²/yr, whichever is less.
    • desired / target value: 0 kBtu/ft²/yr
  • Strategies:

      • Some of the strategies I would like to focus on to achieve this goal are:

    1. Solar Design by maximize the use of daylight by optimizing the orientation of the building and placement of windows based on location, natural ventilations, photovoltaic panels, etc.
    2. Install appliances with high energy efficiency ratings, remove usage of natural gas/fossil fuels for heating, etc.
    3. Advanced building envelop using reflective or cool roof material to help with cooling, highly efficient insulation material
    4. Energy monitoring/Management using advanced energy usage monitoring systems to track real time energy usage/generation.

      5. Goal 2: Water conservation

      To have net zero annual water usage

    5. Measure: Water usage would be measured in gallon per day per person.
    6. Targets:
      • minimally acceptable value: Achieve 80% water usage reduction compared to similar buildings in the area or 20% of 80 gpd per day = 16 gpd per day, whichever is less.
      • desired / target value: net zero annual water usage
    7. Strategies:

        8. Some of the strategies I would like to focus on to achieve this goal are:

      1. Use of reclaimed water where possible
      2. Rain water harvesting
      3. Water condensation system
      4. In built water treatment system
      5. Use native water draught plants for landscaping
      6. Water monitoring system that reads water meter in real time to adjust water usage.

      Goal 3: Use of sustainable and durable materials

      There are 2 possible measuring systems

    8. Measure: LEED rating system, percentage of material recycled/reused or that can be recycled/reused in future.
    9. Targets:
      • minimally acceptable value: For LEED: Gold, 60 points. 30% materials have been recycled and 60% materials can be recycled.
      • desired / target value: For LEED: Platinum, 100 points. 50% materials have been recycled and 75% materials can be recycled.
    10. Strategies:

        11. Some of the strategies I would like to focus on to achieve this goal are:

      1. Stringent Material Selection: Minimal usage of concrete, use recycled material (metal, glass, wood) wherever possible
      2. Local based material to remove environmental impact of large scale transportation
      3. Design to achieve durability based on local environmental conditions.
      4. Modular construction that is flexible and can be adjusted according to requirements.

      Goal 4: Reduced Carbon Footprint

    11. Measure:  Carbon Dioxide equivalent (CO2e), CO2e=Emissions of Gas×GWP (Gllobal Warming Potential)
    12. Targets:
      • minimally acceptable value: 15% less CO2e compared to similar buildings in the area
      • desired / target value: 30% less CO2e compared to similar buildings in the area
    13. Strategies:

        14. Some of the strategies I would like to focus on to achieve this goal are:

      1. Use local based material to reduce carbon footprint by transportation
      2. Maximize recycled material and environmental friendly material usage
      3. Minimize wastage of material by having efficient design
      4. natural lighting & ventilation to reduce carbon emission from energy usage
      5. Use high carbon consuming plants for landscaping to offset carbon footprint

      Goal 5: Cost effective building

      Achieve the above goals without too extravagant increase in the cost of the building design and construction

    14. Measure: USD/sqft of construction
    15. Targets:
      • minimally acceptable value: Building should cost no more than 50% higher than average cost of similar buildings in the area.
      • desired / target value: Building should cost no more than 25% higher than average cost of similar buildings in the area.
    16. Strategies:

        17. Some of the strategies I would like to focus on to achieve this goal are:

      1. Understand and compare the cost of different materials that can give similar results.
      2. Innovation by simplicity, have simple yet innovative design that can be understood and build by contractors with high productivity
      3. Understand tradeoff between local sourced materials and use of prefab/ foreign sourced materials to justify the need of transportation costs.
      4. Make a low rise buildings to decrease structural requirements
      5. Make modular design that decrease customization requirements
      6. Understand the tradeoff between upfront costs and lifetime costs
