Presentation Transcript

Materials
Materials

  • Using more sustainable materials, less materials and materials in the right constructions

  • Materials have their own impacts associated with them

    • Environmental impacts

      • Extraction/production

    • Visual/thermal/acoustic impacts as well

    • Also create the physical space that occupants experience


Materials1
Materials

  • Embodied energy/carbon can be a measure used

    • Measures environmental impact based on extraction, processing, manufacturing, and distribution

  • Over the life of a building this may not be the most important consideration

    • Thermal/structural/acoustic properties

  • Lifecycle of the material

    • Recyclable, biodegradable, made from recycled material or rapidly renewable materials


Energy systems
Energy Systems

  • Produce, use, convert, and store energy for the building

    • Efficient and effective

  • Systems for thermal and visual comfort ALL use energy is some form

  • Energy production and use is the primary driver of greenhouse gas emissions and global warming

    • Also one of the biggest costs throughout the life of the building


Energy
Energy

  • Energy efficient

    • Right technologies for your building

    • Right design strategies for your building

    • Can be measured by kilowatt hours per year, per unit area (energy use intensity or EUI)

  • Get the most out of the system or technology you use


Design
Design

  • Energy system design should be looked at as the whole system

  • Depending on needs/location

    • On site photovoltaic

    • Wind

    • Grid electricity

    • Natural gas

  • Architect defines energy “demand” and the engineer defines how to supply


H2O

  • Inside the building

    • Drinking

    • Cleaning

    • Sanitation

  • Outside

    • Landscaping

    • Wastewater

    • runoff


H2O

  • Fundamental to survival and human health

  • Also in keep systems in balance

  • Measured in both quantity and quality

    • Flowrate of fixtures and capacity of tanks can measure quantity

    • Quality can be measured in a # of ways, different qualities for different uses

    • pH indicators, dissolved or suspended solids and turbidity


H2O

  • Use the right kind of water for the right uses

  • Reuse as much as possible

  • Economize use

    • High efficiency fixtures

  • Capturing rainwater

  • Plumbing systems that separate potable water, grey water and blackwater

  • Purify water on site with living machines or advanced septic systems
